More likely on a server, less on a personally used computer for interactive desktop workloads. - For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.
- The i7-8700K is more power efficient and generates less heat.
- The i7-8700K has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.
i7-7820X
- The i7-7820X has more cores. The benefit of having more cores is that the system can handle more threads. Each core can handle a separate stream of data. This architecture greatly increases the performance of a system that is running concurrent applications.
- The i7-7820X has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.

It also makes possible what tech enthusiasts have been waiting for so long – the MacBook Air with Retina display. We were hoping to see this high-res version of the Air as part of a hardware update at I/O 2014, but all we got there was a MacBook with a minor processor upgrade. That is, there is not much to change the 2013 model for.
The reason Broadwell is so important is simple: there will be more space, and thin laptops can be equipped with high-resolution screens.

Intel goes deep
So how much less will Broadwell be? The miniaturization of the architecture does not mean the reduction of the chips themselves, but of the transistors that make up the «brain» of the processor.
If 22nm transistors are used in Intel Haswell, then Broadwell transistors will be 14nm. In the last eight years, developers have made significant progress in this area.
After all, back in 2006, the first Core processors had similar components measuring as much as 65 nanometers!
If you have no idea what a nanometer is, here’s an example: the average human hair is about 90,000 nanometers thick. Transistors (even the oldest ones) we’re talking about here are incredibly tiny. These are switches that work systemically, performing the most complex tasks that a processor has to face. There are more than a billion of them in a modern processor.

New motherboards and chipsets
Unfortunately, the new LGA 1200 socket will require a new motherboard. Intel has unveiled four chipsets supporting the new line. So the following chipsets are offered to choose from: Z490 and h570 for the most productive solutions and B460 with h510 for more budget systems.
As for the PCIe interface, here it remains version 3.
0. The company reports that it is not yet ready for the transition to PCIe 4.0 and it will appear only in the next generation.
Let’s consider the functionality of each chipset separately.
Z490 specifications
The Z490 chipset is a premium solution with a lot of options: sixteen PCIe 3.0 lanes from the processor (in 1×16, 2×8 or 1×8 + 2×4 configurations) and twenty-four more from the chipset. The Z490, like the h570, uses the DMI version 3.0 bus to communicate between the processor and the chipset.
Also included are six USB 3.2 Gen2x1 ports, ten USB 3.2 Gen 1×1 ports, and fourteen USB 2.0 ports. There are six SATA 6 Gb/s ports. As for other features, they include an updated LAN port — Intel 2.5G Ethernet i219-V supporting speeds up to 2.5Gbps, as well as RapidStorage for RAID 0, 1, and 5.
Of the chipsets shown, only Z490 supports CPU and memory overclocking.
h570 specifications
h570 also offers 16 PCIe 3.0 lanes from the processor, but only in a 1×16 configuration, and twenty more lanes from the chipset.
The number of USBs has also been reduced, to four USB 3.2 Gen 2×1 and up to eight USB 3.2 Gen 1×1. The maximum number of USB 2.0 remains the same and is fourteen ports.
The rest remains unchanged. Six SATA 6Gb/s ports, Intel 2.5G Ethernet and RapidStorage RAID.
B460 specifications
Like the h570, the B460 chipset allows sixteen PCI Express 3.0 lanes from the 1×16 processor and sixteen from the chipset. Six SATA 6Gb/s ports, plus a choice of eight USB 3.2 Gen 1×1 ports and twelve USB 2.0 ports.
As for h510, there is no data yet.
In the table below, we have compiled all the currently known information on new chipsets. Also added for comparison Z390.
| Chipset | Z490 | h570 | B460 | Z390 |
| Overclockable | Yes | — | — | Yes |
| PCIe 3.0 line CPU | 16 | 16 | 16 | 16 |
PCIe 3. 0 chipset line |
24 | 20 | 16 | 24 |
| SLI / Crossfire | Yes | — | — | Yes |
| SATA3 | 6 | 6 | 6 | 6 |
| USB 3.1 | 6 | 4 | 6 | |
| USB 3.0 | 10 | 8 | 8 | 10 |
| USB 2.0 | 14 | 14 | 12 | 14 |
| Support AX WiFi 6 | Yes | Yes | Yes | — |
| 2.5 Gigabit LAN Port | Yes | Yes | Yes | — |
As can be seen from the table, the difference between Z490 and Z390 is negligible.
The new motherboards, as well as the Intel Comet Lake processors, are expected to be available at the end of May. But you also need to take into account the current situation with the coronavirus pandemic, so most likely we will see new items on the shelves of stores in Russia and the CIS countries no earlier than June.

The best Intel Core i7 processors for gaming: specifications, comparison
If you are a gamer, photography or video editor, or just want a more powerful computer, you need a good processor. Despite the great success of Ryzen, many people prefer Intel i7 processors for multitasking and gaming.
But their choice is quite large, and it is not always clear which one will be the best for you. We have reviewed many models in this line and compiled this selection so that you can choose which processor will best suit your specific requirements.
And if you prefer AMD, we have a similar selection for Ryzen processors.
Intel Core i7-9700K
Best processor overall
Pros
- Fast and overclockable
- Eight physical cores
- Outperforms more advanced i9s in terms of value for money in games
Minus
- No multithreading
It’s hard to make a mistake with an Intel processor, but which one is better to choose? If you’re after a multitasking system for gaming and multimedia, you’ll certainly appreciate the performance gains of the Core i7 processors over the i5, but without the additional cost of the i9 chip.. In particular, the i7-9700K for most users is just the golden mean in terms of performance.
This Gen 9 processor with updated Coffee Lake microarchitecture has a TDP of 95W and a base clock of 3.6GHz. With built-in Intel Turbo Boost technology, it can be accelerated up to 4.9 GHz, and the «K» in the model number indicates an unlocked multiplier — that is, this processor can be easily overclocked to even faster frequencies.
In addition, it boasts 12MB of L3 cache and supports dual-channel DDR4-2666 memory configuration.
These features make this processor great for gaming. In addition, it has integrated Intel UHD 630 graphics that can handle many games even without a discrete graphics card (although you will need one for serious games). But its architecture is slightly different from Intel’s premium processors — there is no multi-threading here, doubling the number of virtual cores, but more physical cores. Unless you’re into video editing or content creation that requires multi-threading, the eight powerful i7-9 cores700K will be more than enough for most tasks.
Intel Core i7-8700K
Best processor for gaming
Pros
- Six cores with 12 threads
- Good gaming performance
- Reasonable price
Minus
- The performance is almost the same as other options
To keep up with the powerful Ryzen processors from its main competitor AMD, Intel introduced the Coffee Lake architecture and 8th generation chips, the flagship of which is the Core i7-8700K.
These were the first Intel processors to have their core count increased from four to six. In addition, thanks to multithreading, each core can work as two virtual cores, that is, a total of six cores and 12 processing threads. This improves the performance of the i7-8700 by running more processes at the same time.
Today, there are processors from Intel and AMD that boast high core and thread counts, but with its impressive single-core performance, the i7-8700K remains a fast model at a reasonable price, especially if gaming is your number one priority. A decent base processor frequency of 3.7 GHz is brought to 4.7 GHz using auto overclocking, and it does not heat up very much, so in the appropriate system it can easily be overclocked up to 5 GHz. Despite the presence of integrated UHD 630 graphics, it can reach its full potential only in conjunction with a suitable discrete graphics card, and then you can play in 4K resolution, and in 1080p you will get incredibly high frame rates.
Intel Core i7-7700K
Second best gaming processor
Pros
- Fast 4.2 GHz base clock, up to 4.5 GHz with auto overclocking
- Good value for money
Cons
- Newer and faster alternatives available
- Total four cores (eight threads)
- May overheat
The
Intel Core i7-7700K is a quad-core Kaby Lake processor from the last generation, but it continues to serve gamers and demanding users. The frequency of a single core is 4.2 GHz, and with auto-overclocking with Turbo Boost technology, it rises to 4.5 GHz. The multiplier is unlocked here and there is some room for overclocking if you can successfully deal with power consumption and temperatures, which tend to be quite high.
But even without overclocking, thanks to the high base frequency and multi-threading, the i7-7700K has enough versatility and power for top games and other tasks. The graphics card usually contributes more to the gaming experience than the processor, so the speed of the i7-7700K is sufficient for most systems.
You’ll get performance close to newer processors, but potentially save money on your graphics card, cooling system, and other components of your gaming system.
Intel Core i7-9800X
Best processor for content creation
Pros
- Top performance with eight cores and 16 threads
- Single core high speed
- Use of solder to reduce temperature
Cons
- Expensive
- No integrated graphics
Tasks such as 4K video editing, 3D modeling and streaming require maximum processing power and as many cores as you can find. Intel Core i7-9The 800X, one of the Skylake architecture premium X-series processors, delivers the performance of a powerful workstation in the high-end desktop (HEDT) segment. With eight cores and 16 threads, it’s ideal for multitasking and running applications that support multithreading. This processor is compatible with X299 motherboards and supports 44 PCI Express lanes, allowing you to connect more graphics cards and other components at higher speeds.
The TDP power value is 165W.
The i7-9800X is fast enough for gaming, with a base frequency of 3.8GHz that can be boosted to 4.4GHz with Turbo Boost. In addition, by using special solder (STIM) instead of the thermal paste used in previous processors, Intel has been able to lower the temperature of the i7-9800X and increase overclocking capabilities.
Intel Core i7-7820X
Second best processor for content creation
Pros
- Excellent performance with eight cores and multi-threading
- High frequency 3.6 GHz, up to 4.3 GHz with auto overclocking
Cons
- Expensive
- Thermal paste can limit overclocking
Intel X-Series HEDT processors, built for photography, video editing, and other content creation applications, boast high clock speeds and high core counts to handle any demanding digital workload, from 4K video rendering to 360-degree panoramic video. degree rollers and virtual reality.
One of the brightest representatives is the Intel Core i7-7820X, a processor with a TDP power of 149watts on Skylake architecture with 8 cores and 16 threads that deliver unrivaled multitasking and multi-threading performance. Like other X-series chips, it requires an LGA 2066 socket and Intel’s flagship X299 chipset. And having 28 PCIe lanes opens up huge possibilities in terms of integration into your system.
Those who want to overclock the i7-7820X may be disappointed by using thermal paste instead of solder — not the preferred approach for optimal cooling. However, the 3.6 GHz frequency is already quite good here, which can be increased up to 4.3 GHz thanks to Turbo Boost 3.0, which is quite enough for most games and creative tasks.
Intel Core i7-3770
Pros
- Decent performance with four cores and multithreading
- Good value for money
- Cooler kit
Minus
- Inferior to new models
If you want to stay on budget when choosing a processor and save money on other components, you should look at the Intel Core i7-3770, a decent processor that will do the job well.
This Ivy Bridge chip is manufactured using the old 22nm process. There are four multi-threaded cores, that is, a total of eight threads. While these cores can’t match today’s processors in sheer processing power, they run at a fast 3.4GHz (3.9GHz auto-overclocked).
Only the unlocked version of the 3770K is suitable for overclocking, but even the base version comes with a cooler. In addition, there is an integrated HD 4000 graphics, but to handle most modern games, you will need a discrete graphics card.
Intel Core i7-6950X
Best processor to spend a lot of money on
Cons
- Exorbitant price
- Single core performance slightly lower than
In general, the Intel Core i7 is a mid-range processor. But some models correspond to the premium segment, and their characteristics and prices strictly limit their market niche to the circle of fans and creative professionals.
As for the Intel Core i7-6950X from the Extreme Edition line, its most striking flagship feature is its incredible 10 cores and 20 threads, which makes this processor a monster in video encoding, 3D rendering and other multi-threaded processes.
It also boasts a generous 25MB L3 cache, 40 PCIe 3.0 lanes, and support for quad-channel DDR4-2400 memory. And while for the sake of increasing the number of cores, I had to sacrifice a little single-core performance, and overclocking can be a little difficult, it has a good clock speed of 3.0 GHz, which normally rises to 3.5 GHz. With a discrete graphics card, it’s great for gaming.
Intel Core i7-8086K
Collector’s Choice
Pros
- Nostalgia/historical factor
- Can normally reach 5.0 GHz
- Good performance with six cores and 12 threads
Cons
- High price
- Slightly different from i7-8700
The Intel Core i7-8086K is not only a high-performance processor, but also a true piece of computer history.
This is a limited edition celebrating the 40th anniversary of the iconic Intel 8086 processor, which at 1978 marked the beginning of the x86 microarchitecture, but this 8th generation Coffee Lake model is of interest not only from a historical point of view.
The 6-core, 12-thread processor boasts a lightning-fast 4.0GHz base clock and a maximum single-core Turbo Boost frequency of 5.0GHz, the first consumer processor from Intel to break that bar. In addition, it is completely unlocked, and with the appropriate overclocking, it can run even faster.
Except for the higher frequency, the i7-8086 is absolutely no different from the i7-8700K. It has 12MB Intel Smart Cache, integrated UHD 630 graphics, and supports dual-channel DDR4-2666 memory configuration. Still, it’s a great processor, though perhaps more suited to those who need something special.

you an interesting comparison of this new product with direct and not very competitors. First, a few words about the processor. In 2017, Intel was very generous with gifts: in the first quarter, it introduced the Kaby Lake line to the market with the Intel Core i7-7700K model at the head, and in the fourth — Coffee Lake with the flagship Intel Core i7-8700K.
There are no fundamental changes in the process technology or microarchitecture, but there are still minor improvements. Also, the novelty stands out with the support of 6 cores and 12 threads with a proportional increase in the cache memory of all levels. And in order to keep the thermal package at around 95 W, I had to reduce the base frequency to 3.
7 GHz.
Additionally, it boasts a 2-channel RAM controller with guaranteed support for DDR4-2666 modules. At the same time, the recommended price tag rose from 350 to $359.. And from the unpleasant moments, we note the need to purchase a new motherboard based on Intel 300 series chipsets, although the same Socket LGA1151 connector is used.
The main internal competitor is the aforementioned Kaby Lake predecessor, the Intel Core i7-7700K. It offers only 4 cores and 8 threads, but a higher base frequency of 4.2 GHz. However, its main advantage at the time of preparation of the material was the real price tag, which is $90 below: $370 vs $460.
The second internal competitor is the 6-core Intel Core i7-7800X for the Socket LGA2066 platform. This is the most affordable representative of the Intel Skylake-X series, and in the future it can be replaced even with 10-18-core models of the Intel Core i9 line. The recommended price tag of the Intel Core i7-7800X is $30 higher, and the real one is $20 lower due to the small supply and high demand for the Intel Coffee Lake line.
But we didn’t have it, so this platform will be represented by the 8-core Intel Core i7-7820X. Let’s clarify that its real cost at the moment is $650, that is, it is almost $200 more expensive than the Intel Core i7-8700K.
And the 8-core AMD Ryzen 7 1700 acts as a nominal external competitor, but we didn’t have it either, so we took a slightly more expensive AMD Ryzen 7 1700X. It is characterized by lower clock speeds and a similar TDP. Its average sale price is $390, and the saved $70 can be invested in other components, if, of course, it makes sense to save.
The Intel Core i7-8700K was tested using a GIGABYTE Z370 Ultra Gaming motherboard and was cooled by a Thermalright Archon SB-E X2 cooler. Thanks to the modified BIOS version and the Enhanced Performance option disabled by default, the processor did not boil during nominal operation.

Other systems used ROG Strix X299-E Gaming and ASUS PRIME Z270-A motherboards from ASUS, as well as MSI X370 SLI Plus.
The RAM modules of the Patriot Viper 4 set in all cases worked at a frequency of 3200 MHz with approximately the same timings, and an Inno3D iChill GeForce GTX 1080 X3 was used as a video card. Systems and most games were installed on GOODRAM Iridium Pro series SSDs. More details about test configurations are in the description.
We will compare processors in two stages. First, let’s compare their results in the nominal mode when running synthetic and gaming tests, and then in overclocking.
By tradition, let’s start with AIDA64 , which immediately presents very interesting results. For example, the Intel Core i7-7700K is slightly ahead of the new flagship by 1-3% when working with RAM, but the cache memory of all levels of the new product is faster. The advantage of the representative of the Core X series reaches 91% when working with RAM, and the L1 and L2 cache memory is faster, but L3 is much slower, so it must be accelerated when overclocking.
But Ryzen 7 boasts an 8% advantage only in the speed of reading from RAM.
On the other hand, the data access delay in AIDA64 is the lowest for the 4-core Intel Core i7, and the highest for AMD Ryzen 7.
, and the advantage of the 8-core from Intel is 23%. The AMD Ryzen 7 outperformed in unboxing speed and overall rankings, but lost out in packing speed. On average, its advantage is 4%.
WinRAR also leads the Intel Core i7-7820X, which is 10% ahead of the novelty. In turn, the top Coffee Lake bypasses the representatives of Kaby Lake and Ryzen by 45 and 51%, respectively.
When rendering a scene in Corona , the test model showed the third result, losing 20% to the 8-core Intel Core i7 and 4% to the AMD Ryzen 7. But the 4-core predecessor took 43% more time.
In the V-Ray benchmark, we see a very similar situation: the Intel Core i7-8700K lagged behind the 8-core models by 19 and 3%, and the top Kaby Lake coped with the task 42% slower.
The shortest scene encoding time in the benchmark x265 was predicted for the Intel Core i7-7820X. It is followed by the novelty under consideration, which took almost 4 s more time, which is equivalent to 10%. Its gap from AMD Ryzen 7 is just over a second, and it is separated from the 4-core by more than 12 seconds.
A very interesting situation happened in CineBench R15 : in the CPU test, the processors are located depending on the number of cores and clock frequency, and in OpenGL only the frequency played a key role, so the Intel Core i7-7700K is in the first place here.
We complete the review of synthetics in the complex test RealBench . The novelty has a strong position in the image editing tests and in multitasking mode, which brings it to second place in the overall standings, although the gap from the 8-core Intel Core i7 in this case does not exceed 0.5%. In third place was AMD Ryzen 7, followed by 4-core Kaby Lake.
Now let’s move on to the games, the choice of which was carried out not by the «poke» method, but quite consciously. It’s no secret that there are games with good optimization for multithreading, but there are bad ones. There are exciting projects on new engines, and there are on old ones.
For example, Far Cry Primal is highly dependent on CPU performance in single-threaded mode, and in order not to run into the capabilities of the video card, we switched to HD resolution. GTA V nominally supports multithreading, but its engine is not very fresh, and the optimization is lame. In The Third Witcher, code parallelization is already better, but still, the optimization is far from ideal.
But WATCH_DOGS 2 is good at using additional cores and threads. The test includes popular representatives of heavy online shooters, which are not very clear in terms of the repeatability of the results, but without them there is no way, since I immediately “dislike, unsubscribe and take my friends away”.
And, for example, in Ghost Recon Wildlands, we deliberately decided to rest against the video card and see if there would be any difference between the systems.
In a word, games and settings were chosen in such a way as to explore different classes of projects and different scenarios for their work, making the test more objective and complex.
Let’s start with online mode Battlefield 1 in Full HD resolution with ultra graphics settings. The Intel Core i7-8700K showed the highest minimum frame rate at 103 fps. But the average rate turned out to be 5-8 FPS lower than that of internal competitors. The backlog of AMD Ryzen 7 was up to 13%.
In Assassin’s Creed Origins we left the settings as high as possible, but reduced the resolution to HD so as not to be limited by the video card. According to online reviews, 30% of the processor’s performance is spent on online protection decoding, so it is not surprising that a system with an 8-core Intel Core i7 on board took the lead.
And the top-end Coffee Lake lost even to its predecessor, perhaps due to lower frequencies.
Ultra preset in HD resolution test Far Cry Primal clearly demonstrates the importance of single-threaded performance for older engines. The Intel Core i7-7700K became the undisputed leader, and its 6-core replacement lagged behind by 13-16%. Both 8-core processors were far behind.
Similar graphics and resolution settings were used in the benchmark Rainbow Six Siege . It does better with multi-threading optimization, but single-threaded performance is also very important. Therefore, we have dual power: the Intel Core i7-8700K is 4% ahead of its 4-core predecessor in terms of the minimum indicator, and the latter, in turn, minimally bypasses the new product in terms of average frame rate. Among the 8-core processors, the representative of Intel looks better.
In WATCH_DOGS 2 at ultra settings and HD resolution, we again fix a couple of winners, only now 6- and 8-core representatives of the Intel Core i7 line cannot share the leadership.
The test model by 3 FPS or 4% bypasses its counterpart in the minimum frequency, and he breaks ahead by 2% in the average. By the way, Intel Core i7-7700K and AMD Ryzen 7 also failed to determine a clear leader among themselves.
It would seem that a new game set in the world of Middle-earth should be well optimized for multithreading. And to test it, we ran its benchmark at HD resolution and ultra graphics settings. But the best result was shown by the 4-core Intel Core i7, and the system with the 8-core Intel Core i7 on board did the worst. The Intel Core i7-8700K outperforms the AMD Ryzen 7 in terms of the average frame rate, but slightly loses to it in the minimum frame rate.
Rise of the Tomb Raider is very demanding on the processor, video card, and disk subsystem, so we decided to run it at Full HD and a very high preset in order to load all the nodes to the maximum. If you think that the results were within the margin of error, then we hasten to surprise you.
In terms of the average frequency, the Intel Core i7-7700K takes the clear lead, and in terms of the minimum frequency, the Intel Core i7-8700K. The lag of 8-cores becomes especially obvious precisely in terms of the minimum speed.
Contender for the title of game of the year, PUBG at Full HD resolution and ultra preset, once again proves that it is too early to write off the flagship of the Kaby Lake series. After all, it was he who was 3 FPS or 4% ahead of the 6-core novelty. And they have the same minimum speed. Both 8-cores are well behind the leaders, but AMD Ryzen 7 was able to get ahead of its counterpart.
To run The Third Witcher , almost the maximum graphics and post-processing presets were used, and the resolution was reduced to HD. The 4-core Intel Core i7 again took the palm. Its result: 146 frames / s with drawdowns up to 116. A 6-core changer came close to him, which issued 139FPS with drawdowns up to 110.
And the third place on the virtual podium went to the Intel Core i7-7820X.
Choosing very high graphics settings at Full HD resolution in GTA V , we could hit the graphics card if the game was well optimized for multithreading. In reality, it is very demanding on the performance of the processor in single-threaded mode. Therefore … drumming, the leaders again turned out to be the flagship of the Kaby Lake series. It is ahead of its closest competitor, and part-time 6-core replacement, by 7-17%. AMD Ryzen 7 won the 8-core fight.
We complete the first stage of testing with the benchmark Ghost Recon Wildlands at Full HD and a very high profile of graphic settings. The results were very interesting. The victory was again celebrated by the Intel Core i7-7700K, but its pursuers were 8-core models, and the flagship of the Coffee Lake series came to the finish line last.
