Intel is on the verge of transitioning to 32nm. We’ll see the first parts this year. What do you do with your 45nm fabs when you start moving volume away from them? Make really cheap quad-core Nehalems of course:

I’m talking $196. I’m talking faster than AMD’s entire lineup. I’m talking about arguably the best processor of 2009. I’m talking about Lynnfield, and here’s its backside:

Mmm

I spent much of the past year harping on AMD selling Nehalem-sized Phenom IIs for less than Intel sold Nehalems. With Lynnfield, Intel actually made Nehalem even bigger all while driving prices down. Like I said, what do you do when you’re still making boatloads of money in a recession and are about to start emptying your 45nm fabs?

I should clear things up before we progress much further. Lynnfield is the codename for mainstream 45nm quad-core Nehalem, while Bloomfield refers to the first Nehalem launched at the end of 2008:

Despite being cheaper, Lynnfield is larger than Bloomfield. The larger die is due to one major addition: an on-die PCIe controller.

Bloomfield, The First Nehalem, circa 2008

Lynnfield, Nehalem for All, circa 2009

The pink block to the right of the die is the PCIe controller, that’s 16 PCIe 2.0 lanes coming right off the chip. Say hello to ultra low latency GPU communication. You’d think that Intel was about to enter the graphics market or something with a design like this.

Sacrifices were made to reduce CPU, socket and board complexity. Gone are the two QPI links that each provided 25.6GB/s of bandwidth to other CPUs or chips on the motherboard. We also lose one of the three 64-bit DDR3 memory channels, Lynnfield only has two like a normal processor (silly overachieving Bloomfield).

Intel’s Bloomfield Platform (X58 + LGA-1366)

The sum is that Lynnfield is exclusively single-socket; there will be no LGA-1156 Skulltrail. While the dual-channel memory controller isn’t really a limitation for quad-core parts, six and eight core designs may be better suited for LGA-1366.

Intel’s Lynnfield Platform (P55 + LGA-1156)

The loss of QPI means that Lynnfield doesn’t have a super fast connection to the rest of the system, but with an on-die PCIe controller it doesn’t matter: the GPU is fed right off the CPU.

The Lineup

We get three Lynnfield CPUs today: the Core i7 870, Core i7 860 and the Core i5 750. Intel’s branding folks told us that the naming would make sense one we saw the rest of the «Core» parts introduced; yeah that was pretty much a lie. At least there aren’t any overlapping part numbers (e.g. Core i5 860 and Core i7 860).

The i7 in this case denotes four cores + Hyper Threading, the i5 means four cores but no Hyper Threading. The rules get more complicated as you bring notebooks into the fray but let’s momentarily bask in marginal simplicity.

Processor	Clock Speed	Cores / Threads	Maximum Single Core Turbo Frequency	TDP	Price
Intel Core i7-975 Extreme	3. 33GHz	4 / 8	3.60GHz	130W	$999
Intel Core i7 965 Extreme	3.20GHz	4 / 8	3.46GHz	130W	$999
Intel Core i7 940	2.93GHz	4 / 8	3.20GHz	130W	$562
Intel Core i7 920	2. 66GHz	4 / 8	2.93GHz	130W	$284
Intel Core i7 870	2.93GHz	4 / 8	3.60GHz	95W	$562
Intel Core i7 860	2.80GHz	4 / 8	3.46GHz	95W	$284
Intel Core i5 750	2. 66GHz	4 / 4	3.20GHz	95W	$196

Keeping Hyper Threading off of the Core i5 is purely done to limit performance. There aren’t any yield reasons why HT couldn’t be enabled.

Intel was very careful with both pricing and performance of its Lynnfield processors. I’m going to go ahead and say it right now, there’s no need for any LGA-1366 processors slower than a Core i7 965:

This is only one benchmark, but it’s representative of what you’re about to see. The Core i7 870 (LGA-1156) is as fast, if not faster, than every single LGA-1366 processor except for the ones that cost $999. Its pricing is competitive as well:

For $196 you’re getting a processor that’s faster than the Core i7 920. I’m not taking into account motherboard prices either, which are anywhere from $50 — $100 cheaper for LGA-1156 boards. I don’t believe LGA-1366 is dead, but there’s absolutely no reason to buy anything slower than a 965 if you’re going that route.

We can better compare what are the technical differences between the two processors.

Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

We see that the two processors have an equivalent number of cores, the turbo frequency of Intel Core i5-10300H is bigger, that the thermal dissipation power of Intel Core i5-10300H is less. The Intel Core i5-10300H was started more recently.

Performances :

Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.

In single core, the difference is 44%. In multi-core, the difference in terms of gap is 38%.

CPU-Z is a system information software that provides the name of the processor, its model number, the codename, the cache levels, the package, the process. It can also gives data about the mainboard, the memory. It makes real time measurement, with finally a benchmark for the single thread, as well as for the multi thread.

In single core, the difference is 94%. In multi-core, the difference in terms of gap is 74%.

Cinebench R15 evaluates the performance of CPU calculations by restoring a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, uses sharp and fuzzy reflections, bright areas, shadows, procedural shaders, antialiasing, and so on. The faster the rendering of the scene is created, the more powerful the PC is, with a high number of points.

In single core, the difference is 118%. In multi-core, the difference in terms of gap is 98%.

Cinebench R20 is a multi-platform test software which allows to evaluate the hardware capacities of a device such as a computer, a tablet, a server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant.

In single core, the difference is 126%. In multi-core, the difference in terms of gap is 92%.

Cinebench R23 is cross-platform testing software that allows you to assess the hardware capabilities of a device such as a computer, tablet, server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant. The test scene contains no less than 2,000 objects and more than 300,000 polygons in total.

Therefore, it remains for us to closely monitor the replenishment of the family of processors Intel on the architecture Nehalem . What this review is about.

Appearance and equipment

Before us is a representative of perhaps the most promising (in terms of the mass market) Core i7-8xx family — Intel Core i7-870. The Intel Core i7-870 is the flagship of the line of processors with the Lynnfield core, despite the lower model index, and will remain so, according to Intel’s plans, until the end of 2010, which further fuels our interest in this model.

The packaging of the Intel Core i7-870 indicates that the processor belongs to the LGA 1156 family.

There is a hole on the back wall of the package through which you can see the sticker on the cooler with its marking — E41759-002.

Through the upper «viewing window» we can see the processor itself and the technical parameters of the model available on its heat-distributing cover:

• clock frequency 2.93 GHz;
• 8 MB cache;
• power system requirement PCG 09B.

The country of origin is also indicated here — Malaysia. Unfortunately, we could not find information about the existence of Costa Rican-made Intel Core i7-870 processors, and some models of Intel processors made in Costa Rica had a higher overclocking potential, unlike their Malaysian counterparts. Though it might just be a coincidence.

The Intel Core i7-870 does not differ from the bundle, it is standard for Intel products. In addition to the processor itself, the kit includes:

• cooler E41759-002;
• warranty statement and user manual;
• body sticker.

As for the cooling system, as already mentioned, it is familiar to modern Intel products. The only embarrassing thing is that according to the test results of the Intel Core i7-860, the efficiency of the cooler supplied with the processor was categorically insufficient. Therefore, we recommend that those who are seriously considering buying this solution for the LGA 1156 take care of choosing the appropriate cooling system. Otherwise, the potential of the Intel Core i7-870 model will remain undiscovered.

Model description

Unlike the processors of the Core i7-9xx family, the Intel Core i7-870 is installed in the LGA 1156 socket. But this is not its only difference. Consider the comparative specification of modern models of Intel processors.

Processor Families Intel Core i7 and Intel Core i5

So, as we can see, the Intel Core i7-870 is noticeably different from other representatives of the Nehalem architecture based on the Bloomfield core in the LGA 1366 package. as well as the technology for connecting the processor and PCH (Platform Controller Hub — another innovation of the P55 / X58 platforms, based on the integration of the north bridge functions into the processor). The Intel Core i7-870 uses the DMI (Direct Media Interface) bus.

It should also be noted that in the process of evolution, the model in question lost one of the three memory channels, which resulted in a change in the number of contacts and physical dimensions of the processor, which correspond to the LGA 775 standard (38×38 mm). However, we will disappoint those who still have effective air cooling systems for the mentioned connector in their bins — unfortunately, the cooler fastening mechanism has also undergone changes.

It should be added to the characteristic features of Intel Core i7-870 that, despite belonging to LGA 1156, the processor retained support for Hyper-Threading technology, which has a positive effect on the performance of those optimized for multithreading applications. We will talk about the features of the implementation of Turbo Boost technology in the Intel Core i7-870 a little lower, but for now we note the purpose of this and other supported technologies:

• Intel Turbo Boost — the ability of the processor to independently dynamically adjust the process of increasing performance in resource-intensive applications without a noticeable increase in heat dissipation;

• Intel Hyper-Threading — allows you to execute up to 8 task threads simultaneously by creating virtual cores;

• Intel Smart Cache — cache memory optimization in multi-threaded applications;

• Integrated Memory Controller — Supports two channels of high-speed DDR3 memory up to 1333MHz.

• Intel Virtualization Technology, Intel 64 — provides direct access to the virtual machine, including for 64-bit operating systems;

• Intel Trusted Execute Technology — protection of the system from viruses at the hardware level.

The CPU-Z utility correctly identifies the processor and displays its main technical characteristics. Here it is worth noting, firstly, the low voltage value (at full load it rises to 1.26 V), and secondly, the frequency of the memory controller, which is lower than that of processors with the Bloomfield core. We also see the Hyper-Threading technology in action and mark the core revision — B1.

The speed of caches and working with RAM is also important.

Speed ​​in office use

Core i5-9400

73.7 (+19.1%)

Core i7 870

59.6

Performance in everyday work such as browsers and office programs.

The performance of 1 core has the greatest impact on the result, since most of these applications use only one, ignoring the rest.

Similarly, many professional applications such as various CADs ignore multi-threaded performance.

Speed ​​in heavy applications

Core i5-9400

45. 4 (+27.8%)

Core i7 870

32.8

Performance in resource-intensive tasks loading a maximum of 8 cores.

The performance of all cores and their number has the greatest impact on the result, since most of these applications willingly use all the cores and increase the speed accordingly.

At the same time, certain periods of work can be demanding on the performance of one or two cores, for example, applying filters in the editor.

Data obtained from tests by users who tested their systems with and without overclocking. Thus, you see the average values ​​corresponding to the processor.

Speed ​​of numerical operations

Different tasks require different CPU strengths. A system with few fast cores and low memory latency will be fine for the vast majority of games, but will be inferior to a system with a lot of slow cores in a rendering scenario.

We believe that a minimum 4/4 (4 physical cores and 4 threads) processor is suitable for a budget gaming PC. At the same time, some games can load it at 100%, slow down and freeze, and performing any tasks in the background will lead to a drop in FPS.

Ideally, the budget shopper should aim for a minimum of 4/8 and 6/6. A gamer with a big budget can choose between 6/12, 8/8 and 8/16. Processors with 10 and 12 cores can perform well in games with high frequency and fast memory, but are overkill for such tasks. Also, buying for the future is a dubious undertaking, since in a few years many slow cores may not provide sufficient gaming performance.

When choosing a processor for your work, consider how many cores your programs use. For example, photo and video editors can use 1-2 cores when working with filtering, and rendering or converting in the same editors already uses all threads.

Data obtained from tests by users who tested their systems both with overclocking (maximum value in the table) and without (minimum). A typical result is shown in the middle, the more filled in the color bar, the better the average result among all tested systems.
