• In some games, a processor with a higher clock speed, or with the technical name IPC (Instructions per clock), performs better than other processors with more cores and a lower core frequency.
• The i7-8700K has a higher turbo clock. Turbo Boost is a processor feature that will run at a processor clock speed faster than its base clock speed if certain conditions are present. This will allow older software that runs on fewer cores to run better on newer hardware. Since games are also software, they are also applicable.

Ryzen 5 2600

• Ryzen 5 2600 has higher level 2 cache. Data/instructions that need to be processed can be loaded from fast L2 and the CPU doesn’t have to wait for very slow DDR 9 RAM0012
• Ryzen 5 2600 has higher L3 cache. This is useful when you have significant multi-processor workloads, many computational processes at the same time. Rather on a server rather than a personal computer for interactive workloads.
• Ryzen 5 2600 The Ryzen 5 2600 is more energy efficient and generates less heat.
• Ryzen 5 2600 The Ryzen 5 2600 has a smaller process size. The faster a transistor can turn on and off, the faster it can work. And transistors that turn on and off with less power are more efficient, reducing the operating power or «dynamic power» required by the processor.

Ryzen 5 3600 Review — Testing the New People’s Processor

Review Ryzen 5 3600 — Testing the New People’s Processor

The AMD Ryzen 5 3600 is the successor to the Ryzen 5 2600, one of the people’s favorite processors for its perfect combination of price and performance. The Ryzen 5 3600 is AMD’s new 6-core, 12-thread processor for $200. It operates at frequencies from 3.6 GHz to 4.2 GHz, features a 32 MB L3 cache and 65 W power consumption. The boxed version includes a Wraith Stealth cooler, and the price is similar to that of the Ryzen 5 2600 at launch. We will compare this processor with Intel Core i5-9600K, which costs $255 without a cooler included.

The new Ryzen processor was tested using an MSI X570 Creation motherboard, DDR4-3200 CL14 RAM, and a stock cooler. The 8th and 9th generation Intel Core processors were tested on a Gigabyte Z390 Aorus Ultra motherboard using the same RAM modules but cooled using a Corsair h215i RGB Platinum AIO coolant. In all cases, the MSI Trio GeForce RTX 2080 Ti graphics card was used.

Test Ryzen 5 3600

Overclocking

Conclusion

Cinebench R20

Let’s start with the Cinebench R20 multi-core test, where the Ryzen 5 3600’s results are immediately amazing. In multi-core mode, it matches the Ryzen 7 1800X with just over 3600 points. The Ryzen 5 3600 is 4% faster than the 8700K, nearly 20% faster than the 2600X, and 28% faster than the Ryzen 5 2600.

Compared to the R5 1600, the new R5 3600 is 45% faster. In 2 years, AMD has increased the performance of a $200 processor by almost 50%.

Single-core performance is also impressive, here the Ryzen 5 3600 was only 4% slower than the 3700X and matched the Intel Core i5-9600K processor ahead of the Intel Core 8700K.

WinRar

The WinRAR R5 3600 looks very good, falling short of the Intel Core 8700K by only 4%. But it’s 45% faster than the Core i7-7700K and Ryzen 7 2700X.

7-Zip

When tested with 7-Zip in compression mode, the Ryzen 5 3600 outperforms the R7 2700X. Excellent compression speed, outperforming the Core 8700K by 14%. In unpacked mode, it remains from 8-core Ryzen processors, but even so, the Ryzen 5 3600 is 16% faster than the 8700K.

Adobe Premiere Pro CC 2019

For content creators, the Ryzen 5 3600 is a godsend, it did 4K video work 4% faster than the 8700K. Although the difference doesn’t seem like much, the 8700K is a $360 processor, while the Ryzen 5 3600 is $200.

V-Ray Benchmark

The new processor is 17% faster than the Ryzen 5 2600 and a whopping 32% faster than the Ryzen 5 1600 in V-Ray. The R5 3600 trails the Core i7 8700K in the latest V-Ray Benchmark by 6%.

Corona 1.3 Benchmark

The AMD Ryzen 5 2600 was 5 seconds behind the 8700K in the Corona test, but considering the price difference, that’s a great performance for the R5 3600. in the Blender test, outperforming the Intel Core i7-8700K and easily beating the previous generation Ryzen and i5-9600K, which fell to the bottom of the table.

Power Consumption

Power consumption taken from testing in Blender. The Ryzen 5 3600 used the same amount of power as the quad-core Core i7-7700K and slightly more than the i5-9600K. But at 8W difference, the Ryzen 5 3600 was almost 40% faster in Blender than the Core i5-9600K. In terms of energy efficiency, this is an impressive result.

Assassin’s Creed: Odyssey

In Assassin’s Creed: Odyssey, the Ryzen 5 3600 processor is 1% behind the Core i7-8700K, but a couple of frames ahead in the minimum FPS. 3rd generation Ryzen processors are a little behind at 1440p. Specifically, the R5 3600 is 6% slower than the i7-8700K at 1440p.

Battlefield V

The results for Battlefield V compared to the i7-8700K are a little disappointing, though the Ryzen 5 3600 shouldn’t compete. Compared to the i5-9600K, it delivers 23% more in minimum FPS and delivers the same average FPS.

At 1440p, the i5-9600K outperforms the R5 3600 by 5 frames in average FPS, but lags behind by 18% in minimum FPS, allowing for a smoother AMD-powered gaming experience.

Shadow of the Tomb Raider

In Shadow of the Tomb Raider AMD Ryzen 5 3600 processor matches Intel Core i5-9600K, which is a good result considering the 9600K costs more. Results at 1440p were pretty much the same, with the i5-9600K taking the lead by a few frames. The minimum R5 3600 is much larger than any of the previous generations of Ryzen processors.

The Division 2

Moving on to The Division 2. At 1080p, the R5 3600 outperformed the i5-9600K and took a significant step forward not only from the 2600X, but also from the 2700X. Interestingly, this time at 1440p, the Ryzen 5 3600 was able to beat the i5-9600K. The R5 3600 proved to be much faster here than the R7 2700X and i7-8700K.

Far Cry New Dawn

As expected from Ryzen, performance in Far Cry New Dawn was not great compared to competing Intel processors, but overall gameplay was smooth. At 1440p, the Ryzen 5 3600 lagged far behind the i5-9600K, especially when looking at minimum FPS.

World War Z

World War Z performance was also poor compared to Intel processors, but at over 100 FPS it probably doesn’t matter much. The Ryzen processors in World War Z hit a ceiling of 135 fps, which is very strange considering that Intel processors go up to 150 FPS.

Rage 2

The Ryzen 5 3600 performed well in Rage 2, averaging 160 FPS, not much slower than the i5-9600K.

Hitman 2

When tested in Hitman 2, we see that the Ryzen 5 3600 is 7% slower than the i5-9600K on average FPS. Similar results at 1440p, although here the Ryzen 5 3600 matches the minimum FPS of the i5-9600K.

Total War: Three Kingdoms

In the new Total War: Three Kingdoms, the Ryzen 5 3600 processor produces a higher minimum FPS than 9600K but lower average FPS. At 1440p, the RTX 2080 Ti compares.

Overclocking

Like the 3700X and 3900X, you won’t get much overclocking with the Ryzen R5 3600. The best thing you can do with liquid cooling is overclocking to 4.2 GHz. You’d better enable the PBO + AutoOC feature in the Ryzen Master software. This will increase the multi-core score of Cinebench R20 by only 4%.

PBO + AutoOC improved single-core score by 1.6%, which is clearly not worth the effort and additional power consumption.

Cost per frame

To estimate the cost per frame, add the cost of the cooler to Intel processors. With these adjustments, the Core i5-9600K ships at a total cost of $295, which translates into a cost per frame of $2.18, putting it on par with the Ryzen 7 2700X. The

Ryzen 5 3600 is priced at $1.53 per frame and delivers the same level of performance but costs almost $100 less. This makes the Ryzen 5 3600 better than the 2600X at its current $19 price.5. Considering the efficiency gains and superior performance boost, the Ryzen 5 3600 is totally worth buying.

Conclusion

As expected, the Ryzen 5 3600 is a very good value processor for the money. It will even work on a base motherboard with a B350 chipset, as long as it gets the required BIOS update. For new builds, you can use the B450 chipset and have a powerful platform for just $300. That’s exactly what you’ll pay for the i5-9600K with cooler.

In the future, you could install a Ryzen 7 3700X, a Ryzen 9 3900X, or maybe even a 16-core 3950X there. Those who bought two years ago, say a Ryzen 5 1600 with a B350 motherboard, can now install a Ryzen 5 3600 there with up to 35% gain in games, and up to 45% gain in applications.

For those who are building a new PC from scratch, the Ryzen 5 3600 looks like the best option. It beat the Intel Core i5-9600K in every application test. Plus, you get 12 threads, not just 6. The Intel Core i5 was slightly faster in a few games we tested, but in general the Ryzen 5 3600 was much more powerful. 9

Part 1>> Part 2 >> Part 3

One of the most popular processors of the outgoing decade was the Intel Core i7- 2600K. The design was revolutionary, as it offered a significant jump in performance and efficiency from a single-core processor, and the processor itself was also highly overclockable. The next few generations of Intel processors didn’t look as exciting, and often didn’t give users a reason to upgrade, so the phrase «I’ll stay with my 2600K» became ubiquitous on the forums and resounds even today. In this review, we dusted off the box of old processors and ran the veteran through a set of 2019 benchmarks.years, both factory and overclocked, to make sure it’s still a champion.

Core i7 Family Photo

Why 2600K was defining generation

Sit in a chair, lean back in your chair, and imagine yourself in 2010. That was the year you looked at your aging Core 2 Duo or Athlon II system and realized it was time for an upgrade. You are already familiar with the Nehalem architecture, and you know that the Core i7-920 accelerates well and beats competitors. It was a good time, but suddenly Intel changed the balance of the industry and created a truly revolutionary product. Echoes of nostalgia for which are still heard.

Core i7-2600K: the fastest Sandy Bridge (up to 2700K)

This new product was the Sandy Bridge. AnandTech released an exclusive review and the results were almost unbelievable, for many reasons. According to our tests at the time, the processor was simply incomparably superior to anything we had seen before, especially considering the thermal monsters of the Pentium 4 that had been released a few years earlier. The core upgrade based on Intel’s 32nm process was the biggest turning point in x86 performance, and we haven’t seen a similar breakthrough since. It will take AMD another 8 years to get their moment of glory with the Ryzen series. Intel, on the other hand, managed to take advantage of the success of its best product, and take the place of the champion.

In this basic design, Intel did not skimp on innovation. One of the key elements was the micro-op cache. This meant that newly decoded instructions that were needed again are taken already decoded, instead of wasting energy on re-decoding. With Intel with Sandy Bridge, and much later with AMD with Ryzen, enabling micro-op cache has been a miracle for single-threaded performance. Intel also began to improve concurrent multithreading (called HyperThreading for several generations), gradually working on dynamic distribution of computational threads.

The quad-core design of the top processor at launch, the Core i7-2600K, became the mainstay of products in the next five generations of Intel architecture, including Ivy Bridge, Haswell, Broadwell, Skylake, and Kaby Lake. Since Sandy Bridge, although Intel has moved to a smaller process and taken advantage of lower power consumption, the corporation has not been able to recreate this exceptional jump in net instruction throughput. Later, the growth for the year was 1-7%, mainly due to an increase in operational buffers, execution ports and command support.

Because Intel couldn’t replicate the Sandy Bridge breakthrough, and the microarchitecture of the cores was the key to x86 performance, users who bought the Core i7-2600K (I bought two) stayed with it for a long time. Largely due to the expectation of another big jump in performance. And their frustration grows over the years: why invest in a 4.7GHz quad-core Kaby Lake Core i7-7700K when your quad-core Sandy Bridge Core i7-2600K is still overclocked to 5.0GHz?
(Intel’s responses are usually about power consumption and new features like running GPUs and storage over PCIe 3.0. But some users weren’t satisfied with those explanations.)

That’s why the Core i7-2600K defined the generation. It remained in place, initially to Intel’s delight, and then to its disappointment when users were unwilling to upgrade. Now, in 2019, we understand that Intel has already gone beyond four cores in its mainstream processors, and if the cost of DDR4 is tough for the user, he can either move to a new Intel system or choose the AMD path. But here’s the question, how does the Core i7-2600K handle 2019 workloads and games?of the year; or more specifically, how does an overclocked Core i7-2600K do?

Spot the difference: Sandy Bridge, Kaby Lake, Coffee Lake

In truth, the Core i7-2600K was not the fastest mainstream Sandy Bridge processor. A few months later, Intel brought the slightly more «high-frequency» 2700K to market. It performed much the same and overclocked similarly to the 2600K, but it cost a bit more. By this time, the users who saw the performance jump and upgraded were already on the 2600K and stayed with it. 9The 0003

Core i7-2600K was a 32nm quad-core processor with HyperThreading technology, with a base frequency of 3.4GHz, a turbo frequency of 3.8GHz, and a nominal TDP of 95W. At that time, Intel’s TDP was not yet out of touch with reality: in our testing for this article, we saw a peak power consumption of 88 watts on a non-overclocked CPU. The processor shipped with integrated Intel HD 3000 graphics and supported DDR3-1333 memory by default. Intel set a price of $317 at the chip’s launch.

For this article, I used a second i7-2600K that I bought when they first came out. It was tested both at stock frequency and overclocked to 4.7 GHz on all cores. This is an average overclock — the best of these chips run at 5. 0 GHz — 5.1 GHz in everyday mode. In fact, I remember well my first Core i7-2600K running at 5.1 GHz on all cores, and even 5.3 GHz (also on all cores) when during an overclocking competition in the middle of winter, at room around 2C, I used a powerful liquid cooler and 720mm radiators. Unfortunately, over time, I damaged this chip, and now it does not boot even at the nominal frequency and voltage. Thus, we have to use my second chip, which was not as good, but still able to give an idea of ​​the performance of the overclocked processor. When overclocking, we also used overclocked memory, DDR3-2400 C11.
It’s worth noting that we’ve moved from Windows 7 to Windows 10 since the launch of the Core i7-2600K. The Core i7-2600K doesn’t support AVX2 instructions, and wasn’t built for Windows 10, so it’ll be especially interesting to see how that translates into results.

Core i7-7700K: Intel’s latest quad-core HyperThreading Core i7 processor

Intel’s fastest and newest (and last?) quad-core HyperThreading processor was the Core i7-7700K, a member of the Kaby Lake family . This processor is built on Intel’s improved 14nm process, running at a base frequency of 4.2GHz and a turbo frequency of 4.5GHz. Its TDP with a power rating of 91 watt in our testing showed a power consumption of 95 watts. It comes with Intel Gen9 HD 630 graphics and supports standard DDR4-2400 memory. Intel released the chip with a list price of $339.
Simultaneously with the 7700K, Intel also released its first overclockable dual-core hyperthreaded processor, the Core i3-7350K. In this review, we overclocked such a Core i3 and compared it to the Core i7-2600K at factory settings, trying to answer the question of whether Intel managed to achieve dual-core processor performance similar to their old quad-core flagship. In the end, while the i3 had the upper hand in single-threaded performance and memory handling, the lack of a couple of cores in the account made most tasks too much work for the Core i3.

Core i7-9700K: Intel’s latest pinnacle of Core i7 (now with 8 cores)

Our latest processor to test is the Core i7-9700K. This generation is no longer the flagship of Coffee Lake (now the i9-9900K), but has eight cores without hyperthreading. Comparing it to the 9900K, which has twice as many cores and threads, makes no sense, especially when the i9 is priced at $488. In contrast, the Core i7-9700K retails for «only» $374, with a base frequency of 3.6 GHz and a turbo frequency of 4.9GHz. Its TDP is specified by Intel at 95W, but on a consumer motherboard, the chip consumes ~125W at full load. DDR4-2666 memory is supported as standard.

The Core i7-2600K is forced to work with DDR3, supports PCIe 2.0 rather than PCIe 3.0, and is not designed to work with NVMe drives (which are not included in this test). It will be interesting to see how close the overclocked veteran is to the Core i7-7700K, and what kind of gains we see when moving to something like the Core i7-9700K.

Sandy Bridge: Core architecture

In 2019, we are talking about 100-200mm2 ICs with up to eight high-performance cores and built on the latest Intel or AMD GlobalFoundries/TSMC process technology. But the 32nm Sandy Bridge was a different beast. The manufacturing process was still flat, with no FinFET transistors. The new CPU has implemented the second generation of High-K and achieved 0.7x scaling compared to the previous, larger 45nm process. The Core i7-2600K was the largest quad-core chip, and housed 1.16 billion transistors at 216mm2. By comparison, the latest 14nm Coffee Lake processor packs eight cores and over 2 billion transistors in a ~170mm2 footprint.

The secret to the huge performance leap lies in the microarchitecture of the processor. Sandy Bridge promised (and delivered) significant performance at the same clock speed over the previous generation of Westmere processors, and also set the baseline for Intel’s chips for the next decade. Many key innovations first hit retail with the introduction of Sandy Bridge, and then iterated and improved over many iterations, gradually reaching the high performance we enjoy today.

In this review, I have relied heavily on Anandtech’s initial 2010 microarchitecture report on the 2600K. Of course, with some additions based on the modern look at this processor.

Brief overview: out-of-order CPU core

For those new to processor design, here’s a quick overview of how out-of-order processors work. In short, the kernel is divided into external and internal interfaces (front end and back end), and data first enters the external interface.

In the frontend, we have prefetchers and branch predictors that will predict and fetch instructions from main memory. The idea is that if you can predict what data and instructions will be needed in the near future (before they are needed), you can save time by placing this data close to the kernel. The instructions are then put into a decoder, which converts the bytecode instruction into a series of «micro-ops» that the kernel can then process.

There are different types of decoders for simple and complex instructions — simple x86 instructions are easily mapped to a single micro-op, while more complex instructions can be decoded to more operations. The ideal situation is to have the lowest possible decoding ratio, although sometimes instructions can be split into more micro-ops if these operations can be executed in parallel (instruction-level parallelism or ILP).

If the kernel has a micro-op cache, aka uOp cache, then the results of each decoded instruction are stored in it. Before an instruction is decoded, the kernel checks to see if that particular instruction has been recently decoded, and if successful, uses the result from the cache instead of re-decoding, which consumes power.

Micro-ops are now placed in an allocation queue. A modern kernel can determine if instructions are part of a simple loop, or if uOps (micro-ops) can be combined to speed up the whole process. The uOps are then fed into the re-order buffer, which forms the «back end» of the kernel.

In the backend, starting from the re-order buffer, uOps can be rearranged depending on where the data needed by each micro-op is located. This buffer can rename and allocate micro-ops depending on where they should go (integer operations or FPs) and, depending on the kernel, it can also act as a mechanism for removing completed instructions. After re-ordering, the uOps buffers are fed into the scheduler in the right order to make sure the data is ready and maximize the uOp throughput.

Scheduler sends uOps to execution ports (to perform calculations) as needed. Some kernels have a single scheduler for all ports, however in some cases it is split into a scheduler for integer/vector operations. Most out-of-order kernels have 4 to 10 ports (some more), and these ports do the necessary calculations to get the instruction to «pass» through the kernel. Execution ports can take the form of a load module (load from cache), a store module (store in cache), an integer math module, a floating point math module, as well as vector math operations, special division modules, and some others for special operations. . After the execution port has completed, the data can be stored in a cache for reuse, placed in main memory; at this time, the instruction is sent to the delete queue, and finally deleted.

This brief overview does not cover some of the mechanisms that modern kernels use to facilitate data caching and retrieval, such as transaction buffers, stream buffers, tagging, etc. Some mechanisms are iteratively improved with each generation, but usually when we talk about «instructions per clock» as a measure of performance, we aim to «pass» as many instructions as possible through the core (through the frontend and backend). This figure depends on the speed of decoding at the front end of the processor, instruction prefetching, buffer re-order, and the maximum use of execution ports along with the removal of the maximum number of executed instructions per clock cycle.

With that said, we hope that the reader will be able to better understand the Anandtech test results obtained during the launch of Sandy Bridge.

Sandy Bridge frontend

The Sandy Bridge CPU architecture looks evolutionary at a glance, but it is revolutionary in terms of the number of transistors that have changed since Nehalem/Westmere. The most important change for Sandy Bridge (and all microarchitectures after it) is the micro-op cache (uOp cache).

Sandy Bridge introduced a micro-op cache that caches instructions after they are decoded. There is no complex algorithm here, the decoded instructions are simply stored. When the Sandy Bridge prefetcher receives a new instruction, it first looks for the instruction in the micro-op cache, and if it is found, then the rest of the pipeline works with the cache, and the frontend is disabled. The decoding hardware is a very complex part of the x86 pipeline, and turning it off saves a significant amount of power.

This is a direct-mapped cache, and can store approximately 1.5 KB of micro-ops, which is effectively equivalent to a 6 KB instruction cache. The micro-op cache is included in the L1 instruction cache, and its Hit Rate reaches 80% for most applications. The micro-op cache has a slightly higher and more stable throughput than the instruction cache. The actual L1 instruction and data caches have not changed, they are still 32 KB each (64 KB L1 in total).

All instructions coming from the decoder can be cached by this mechanism, and, as I said, there are some special algorithms in it — simply, all instructions are cached. Long-unused data is deleted when space runs out. The micro-op cache may seem similar to the trace cache in the Pentium 4, but with one significant difference: it does not cache traces. It is simply an instruction cache that stores micro-ops instead of macro-ops (x86 instructions).

Along with the new micro-op cache, Intel also introduced a completely redesigned branch prediction module. The new BPU is roughly the same as its predecessor, but much more accurate. The increase in accuracy is the result of three major innovations.

The standard branch predictor is a 2-bit branch predictor. Each branch is marked in the table as accepted / not accepted with the corresponding reliability (strong / weak). Intel found that almost all of the branches predicted by this bimodal predictor have «high» confidence. Therefore, in Sandy Bridge, the bimodal branch predictor uses one confidence bit for multiple branches, rather than one confidence bit for each branch. As a result, you will have the same number of bits in the branch history table as before, representing many more branches, resulting in more accurate predictions in the future.

Sandy Bridge: near core

With the rise of multi-core processors, managing the flow of data between cores and memory has become an important topic. We have seen many different ways of moving data around the CPU, such as crossbar (cross), ring (ring), mesh (grid) topologies, and, more recently, completely separate I / O chips. The battle of the next decade (2020+), as mentioned earlier by AnandTech, will be the battle of inter-core connections, and it is already underway.
The peculiarity of Sandy Bridge is precisely that it was the first consumer CPU from Intel that used a ring bus connecting all cores, memory, last-level cache and integrated graphics. It’s still the same design we see in today’s Coffee Lake processors.

Ring bar

In Nehalem/Westmery Bridge, a GPU and a video transcoding engine are added to the chip that share the L3 cache. And instead of running more wires to L3, Intel introduced the ring bus.

Architecturally, this is the same ring bus used in Nehalem EX and Westmere EX. Each core, each L3 cache (LLC), integrated GPU, media engine, and system agent (funny name for a northbridge) are attached to the ring bus. The bus consists of four independent rings: a data bus, a query bus, an acknowledgment bus, and a status monitoring bus. Each call to any of the rings can transfer 32 bytes of data per cycle. As the number of cores and cache size increase, your cache bandwidth increases accordingly.

Each core ends up with the same amount of L3 cache bandwidth as high-end Westmere processors — 96 GB/s. The total throughput of Sandy Bridge is 4 times higher than the quad-core Westmere, because it is simply multiplied by the number of cores, and is 384 GB / s.

This means that L3 latency has been significantly reduced from about 36 clocks in Westmere to 26 — 31 clocks in Sandy Bridge (with some variable cache latency that depends on which core is accessing which cache chunk). Also, unlike Westmere, the L3 cache now runs at the core clock speed — the un-Core concept still exists, but Intel calls the non-core part the «system agent», and no longer includes the L3 cache in it. (The term «un-Core» is still used today to describe interconnects.)

With L3 cache running at core speed, you get the benefits of a much faster cache. The downside is that L3 overclocks along with the CPU cores when turbo or idle modes are enabled. If the GPU needs L3 when the core frequency is down, the L3 cache will not perform as fast as if it were independent. Or the system will have to overclock the core and consume additional power.

The L3 cache is divided into fragments, each of which is associated with a separate core. Because Sandy Bridge has a fully accessible L3 cache, each core can address the entire cache. Each fragment has its own bus access controller, and a complete cache pipeline. Westmere had one cache pipeline and a queue to which all cores sent requests, but in Sandy Bridge they are distributed across cache segments. The use of a ring bus means that adding new access points to the bus has ceased to critically affect the size of the matrix. Even though each user on the ring gets their own controller, the data always takes the shortest path. Bus control is distributed throughout the ring, and as a result, each module «knows» whether there was a free slot on the bus one cycle ago.

System agent

For some reason, Intel stopped using the term un-core in SB, and in Sandy Bridge called this part «system agent». (Again, nowadays un-core is back in vogue for interconnects, I/O, and memory controllers). The system agent is a traditional Northbridge. You have 16 PCIe 2.0 lanes available, which can be divided into two x8 lanes. There’s a redesigned dual-channel DDR3 memory controller that finally delivers memory latency around Lynnfield levels (Clarkdale moved the memory controller from the CPU to the GPU).

The system agent also has a DMI interface, a video output unit, and a PCU (power control unit). The SA clock speed is lower than the rest of the core and has a separate power circuit.

Sandy Bridge Graphics

Another significant improvement in Sandy Bridge’s performance over Westmere is graphics processing. While CPU cores show a 10-30% performance improvement, Sandy Bridge’s graphics performance is simply twice that of pre-Westmere (Clarkdale/Arrandale) Intel products. Despite the jump from 45nm to 32nm, graphics processing speed improves thanks to a significant increase in IPC.

The Sandy Bridge GPU uses the same 32nm transistors as the CPU cores. The GPU is in its own little world in terms of power and frequency. The GPU can be turned off or on regardless of the processor. Graphics turbo is available for both desktop and mobile processors.

The GPU is treated as an equal citizen in the world of Sandy Bridge, and gets full access to the L3 cache. The graphics driver controls what goes into the L3 cache, and you can even limit the amount of cache that is available to the GPU. Storing graphics data in cache is particularly important because it reduces main memory accesses, which are costly in terms of both performance and power consumption. But rebuilding the GPU to use the cache is not an easy task.

SNB graphics (internal name Gen 6) make extensive use of fixed-function hardware. The idea is this: everything that can be described using a fixed function, which must be implemented by a hardwired fixed function. The advantage is performance, power, and reduced die size, albeit at the expense of flexibility.

Shader firmware consists of shaders/cores/execution units, which Intel calls EU. Each EU can receive instructions from multiple threads. The internal ISA is mapped one-to-one with most of the DirectX 10 API instructions, which means a CISC-like architecture. Moving from a one-to-one API to instruction mapping increases IPC by effectively increasing the width of the EU.

There are other improvements in the EU. The transcendental math is handled by the hardware in the EU and its performance has been greatly improved. Intel then reported that the sine and cosine operations are now several orders of magnitude faster than pre-Westmere graphics.
In previous Intel graphics architectures, the register reallocated on the fly. If a thread needs fewer registers, the remaining registers can be allocated to another thread. While this was a great approach to save die area, it proved to be a performance limiter. Often streams could not be processed because there were no registers available to use. Intel increased the number of registers per thread, first from 64 to 80, and then to 120 for Sandy Bridge. Downtime scenarios due to lack of registers have been significantly reduced.

In sum, all these improvements have doubled the instruction throughput in the EU.

There were two versions of the Sandy Bridge GPU at launch, one with 6 EU and one with 12 EU. All mobile processors (at launch) use 12 EU, while desktop SKUs can use 6 or 12 depending on the model. Sandy Bridge was a step in the right direction for Intel, as integrated graphics began to become mandatory for consumer products, and Intel gradually began to increase the percentage of chip area devoted to GPUs. Contemporary (2019d.) similar level desktop processors have 24 EU (Gen 9.5), while future 10nm processors will have ~64 EU (Gen11).

Sandy Bridge Media Engine

Next to the Sandy Bridge GPU is the media processor. Media processing in SNB consists of two main components: video decoding and video encoding.

The hardware accelerated decoding engine has been improved compared to the current generation: now the entire video pipeline was decoded using fixed function modules. This contrasts with Intel’s pre-SNB design, which uses an EU array for some video decoding steps. As a result, Intel claims that the power consumption of the SNB processor is halved when playing HD video.

The video encoding engine was a brand new addition to Sandy Bridge. Intel took ~3 minutes of original 1080p 30 Mbps video and transcoded it to iPhone 640 x 360 video format. The whole process took 14 seconds and finished at approximately 400 frames per second.

The principle of fixed function encoding/decoding is now common in any graphics hardware for desktops and even smartphones. At that time, Sandy Bridge used 3mm2 matrices for this basic encoding/decoding structure.

New Aggressive Turbo

Lynnfield was the first Intel processor to actively promote the idea of ​​dynamically increasing the clock speed of active processor cores while disabling idle cores. The idea is that if you have a TDP of 95W for a quad-core processor, but three of those four cores are idle, then you can increase the clock speed of one active core until you hit the turbo limit.

All current generation processors assume that the processor reaches its turbo power limit immediately after turbo is enabled. In reality, however, the processor does not heat up instantly — there is a period of time when the processor does not dissipate its full power consumption and heats up.

Sandy Bridge takes advantage of this feature by allowing the PCU to overclock active cores above TDP for short periods of time (up to 25 seconds). The PCU monitors the available thermal budget during idle time and spends it when the CPU load increases. The longer the processor is left idle, the greater the margin by which TDP can be exceeded. As a result, when a workload occurs, the CPU turns on the turbo at an over TDP, and downclocks again when the CPU heats up, eventually stalling at its TDP. Although the SNB may go beyond its TDP, the PCU will not allow the chip to exceed its reliability limits.

Both CPU and GPU Turbo can work in tandem. Workloads that rely heavily on GPUs running on SNB may cause CPU cores to drop and GPUs to clock up. Also, CPU-bound tasks can lower the GPU frequency and increase the CPU frequency. Sandy Bridge as a whole turned out to be a much more flexible mechanism than anything that was created before it.

Second generation AMD Ryzen: finally official presentation

Leaks on AMD’s new CPUs, the updated Ryzen line, have been circulating on the Web for quite a long time — in fact, these are not even «streams», but full-flowing information flows. It seems that Ryzen 2nd Gen was almost known even before the official announcement — but nevertheless, it was very interesting to get first-hand information, so we took the opportunity and attended AMD’s presentation, which the company held on April 12 in Munich.

We help

You could already learn most of the information provided from our news “AMD announces 2nd generation Ryzen processors”, published immediately after the presentation, however, the company asked to hold some of the information until April 19th. Well, the “H” hour has finally arrived, and we can tell in more detail what happened a week ago at the Steigenberger Hotel in Munich.

So, Ryzen 2nd Gen is not Ryzen 2, we are still waiting for its release (maybe next year?), It is an updated and improved «first» Ryzen, built on the Zen + architecture. But — in order. Jim Anderson, senior vice president and general manager of AMD’s Computer and Graphics Division, spoke to reporters first.

He “started from afar” — remembered the release of the first Ryzen in 2017 and how it affected the market (read: made Intel stir), and that in addition to twenty different first-generation Ryzen processors, AMD then also released high-performance Radeon RX Vega GPUs and the EPYC server processor line — according to Jim, the release of three products of this level in one year means that AMD is returning to high-performance «computing». In support of these words, he recalled the first desktop 16-core Ryzen Threadripper processor, as well as Ryzen Mobile, which appeared at the end of the year, in which, quote, “Zen met Vega”, which made it possible to obtain high gaming performance in thin laptops without a discrete graphics card (according to He said the company expects mobile Ryzen solutions from five major laptop manufacturers in the first half of 2018).

And of course, he couldn’t help but spit on Intel, mentioning the «Ryzen effect»: «manufacturer competition is always good for the consumer, look — Intel had 4 cores in desktop systems for 10 years, but after the appearance of the eight-core AMD Ryzen 7 In the 1800s there were suddenly six; For thin laptops, Intel has been offering dual-core processors since 2010, and after the release of the AMD Ryzen 7 2700U, Intel also suddenly had quadcores.

2018, according to Jim, should be even more productive for AMD — Ryzen processors with Vega graphics have already been released for both ultra-thin laptops and desktop systems. In the coming months, mobile Ryzen PRO is expected, again with Vega, in the second half of the year — the second generation of Ryzen PRO for business and Ryzen Threadripper for «ultimate» desktop systems with maximum performance; and, of course, today’s official release of the main character of this presentation — Ryzen 2nd Gen, made according to the 12 nm process technology, the first processor based on the Zen + architecture.

So, the flagship processor in the second generation of Ryzens is the Ryzen 7 2700X: base clock speed of 3.7 GHz (4.3 GHz in Max Boost mode), 20 MB cache, 8 cores and 16 threads, comes with a proprietary cooler Wraith Prism, MSRP $329. The younger version of this processor, without the X index, costs $30 less — it has a slightly lower frequency (3.2 GHz / 4.1 GHz), the same number of cores and threads, the same amount of cache memory, and a simpler bundled cooler Wraith Spire. The second generation also includes two versions of the Ryzen 5 2600: the older 2600X (6 cores, 12 threads, 19MB cache, frequencies 3. 6 GHz/4.2 GHz, recommended price $229) and the younger one, with frequencies lowered to 3.4 GHz/3.9 GHz, priced at $199.

The rest of the presentation was mainly based on comparison with competitive models from Intel, and the main idea was “the same performance in games, higher performance in applications, and all this for less money, plus a cool cooler in the kit «.

So, according to Jim Anderson, the second generation of Ryzen performs much better in multi-threaded computing — photo editing, video, audio and other typical tasks for the average user are performed on average 20% faster than on the «analogue from Intel» .

In more detail on performance and other technical details, the next speaker — Joe Macri (Joe Macri), CTO of AMD’s client direction, dwelled on.

According to him, when developing the updated Zen+ architecture, on which the second generation of AMD Ryzen is based, special attention was paid to reducing memory access latency: compared to Zen, the new architecture boasts 11% lower memory access latency , by ~15% — to the cache memory of the first and third levels, and by a third less — to the cache memory of the second level. As a result, this made it possible to obtain higher performance in single-threaded calculations (3% more instructions per cycle compared to Zen).

In addition, the transition of GlobalFoundries (chip manufacturer for AMD) to the new 12 nm process technology allowed us to raise the maximum frequencies by ~250 MHz, and overclocking of all cores can now reach 4.2 GHz, and the voltage at similar frequencies is lower by an average of 50 mV compared to first generation Ryzen. In more understandable numbers, the benefit of moving to 12 nm sounds something like this: up to 11% less power consumption at the same frequencies, or up to 16% more performance at the same TDP.

The updated Precision Boost 2 technology, included in the AMD SenseMI proprietary “set,” is designed to get the highest possible performance in each specific task. With its help, the system automatically raises the processor frequency to a certain safe maximum value, if it «sees» the need and opportunity for this (taking into account the ambient temperature, supply voltage, etc. ). And if the first version of Precision Boost operated with only two concepts “load of 1-2 threads” and “load of 3 or more threads” (in the second case, immediately significantly limiting the maximum possible frequency), then Precision Boost 2 offers a linear graph for reducing the maximum frequency by depending on the number of threads, which allows the processor to work at higher frequencies in case of incomplete loading (but more than two threads). The effect of this technology was illustrated by the results in the Cinebench R15 benchmark, where the Ryzen 7 2700X at the same ambient temperature, in automatic mode, was able to demonstrate a 4% increase in performance when switching from a “regular cooler” to a proprietary Wraith Prism, and 7% -ny — on Noctua NH-D15S.

If we talk about the performance of new processors compared to solutions from a competitor — according to AMD measurements, in multi-threaded computing, the Ryzen 7 2700X is faster than the Intel Core i7 8700K by an average of ~ 21% in popular benchmarks and application applications like Cinebench R15, Blender, Handbrake, etc.

In games, of course, the situation is different, here AMD calls the performance of these two processors «virtually identical», demonstrating on charts its own results in a dozen popular gaming benchmarks in 1080p and 1440p (which differ minimally from each other, and not always in in favor of Intel). Almost similar performance in applications and games is shown for the younger «couple» — AMD Ryzen 5 2600X vs Intel Core i5 8600K. As Joe Macri summed up this part of the presentation, «the player is unlikely to understand whose system he is playing on — ours or Intel, because if there is a difference in performance, it is so small that the average person will not notice it.»

And the last, third speaker of the evening was Travis Kirsch, AMD’s director of client solutions management.

He told how important the opinion of its users is for the company, to which they listen very carefully — so in the second generation of Ryzen AMD, as before, uses solder: according to the company, this allows to reduce the temperature regime by at least 10 degrees compared to with thermal paste. This is good news for overclockers, as is the fact that all second generation Ryzen processors have an unlocked multiplier. Also, the complete coolers of the Wraith series are aimed at enthusiasts, which are very different from what we used to call “boxed” coolers — for example, the older one, Prism (comes bundled with the flagship Ryzen 7 2700X), direct contact of heat pipes with the processor, noise level does not exceed 39dB, there is support for switchable fan speed profiles, independent RGB lighting for three different elements (plus the ability to turn it off completely “for RGB haters”) and “improved motherboard compatibility”, so that it can also be used in compact systems.

Separately, Travis mentioned AMD’s proprietary overclocking utility Ryzen Master, which in the new version 1.3 has learned to display extended information on the capabilities of the motherboard, has received a built-in stability test, etc. All this combined, Travis summed up, makes overclocking the new Ryzen processors very easy and yet effective.

AMD offers Ryzen 2nd Gen processors as part of its existing Socket AM4 platform (scheduled to support it until at least 2020) to maintain compatibility with motherboards already released (which will require a BIOS update — you will either need to do it yourself or » look for 300-series chipset motherboards with the AMD Ryzen Desktop 2000 Ready sticker).

Travis Kirsch also spoke about the new top-end AMD X470 chipset — motherboards based on it will receive an optimized power scheme for overclocking the processor, support for memory modules with a higher frequency and reduced power consumption in idle mode. In addition, the X470 supports AMD StoreMI technology, which combines all drives, SSD and HDD, into a kind of “pool” (adding up to 2 GB of RAM to it) and creates a single logical drive, which speeds up the operating system and launches installed games. (StoreMI automatically transfers the most used files to the fastest storage in the system). Theoretically, this should help in the case when a relatively small system SSD is installed in the computer, and all games and applications are on a more capacious and slower HDD (according to data voiced by AMD, using StoreMI on a combination of «NVMe SSD + HDD + RAM» leads to a threefold acceleration the launch of the game World of Warcraft and almost ten times — applications like browsers and text editors) — but how effectively this technology works in real conditions, you need to watch «live», of course.
