i7-8700
  • The i7-8700 has higher Level 2 Cache. Data/instructions which have to be processed can be loaded from the fast L2 and the CPU does not have to wait for the very slow DDR RAM
  • The i7-8700 has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
  • The i7-8700 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 i7-8700 has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
  • 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 i7-8700 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.
i5-9400
  • The i5-9400 is more power efficient and generates less heat.
  • The i5-9400 has a smaller process size. The faster a transistor can toggle on and off, the faster it can do work. And transistors that turn on and off with less energy are more efficient, reducing the operating power, or “dynamic power consumption,” required by a processor.

Comments-10900K and i5-9400F.

Budget six cores versus top ten

So, in the latest tenth generation of Intel Core 10 gen processors for the mass platform (not HEDT) the number of cores in the flagship Intel Core i9-10900 K reached ten for the first time. And with Hyper-Threading technologies, there were twenty computing threads.

This «armament» is impressive.

We were wondering, how much faster is this cool new processor than the 6-core i5-9400 F , which can be called a real «popular» choice for its popularity and good performance-price ratio?

For those who don’t know, the 10th generation of Intel Core desktop processors are still produced using the same 14nm process technology.

You can see that the thickness of the textolite in the new Intel Core i9-10900K (on the left in the photo) has become more

gen are not compatible with previous generation motherboards.

They have a new LGA1200 socket and require new motherboards based on Intel 400 series chipsets to work.

The thing is that at loads on all nuclei using the maximum Boost-frequency Intel Core 9 K is strong TDP 125 W .

For example, in our Cinebench R20 test with a multi-threaded load, according to HWiNFO, the power consumption of the i9-10900K was about 205 watts. And if you use stress tests like Prime95 will be even higher.

Not every, even a powerful cooling system can cope with such a load.

For example, the rather powerful ASUS ROG Strix LC 240 RGB CO used by us was already at its limit at loads above 200 W. The processor temperature climbed above the 80 ° C mark.

The user, through the settings in the BIOS of the motherboard, is given a choice: either limit power consumption at a standard level, but then the core frequencies will not be so high under multi-threaded load, or remove the restrictions, reporting that the processor will be able to allocate a lot heat and this will have to be solved by installing really powerful cooling.

In the «normal» mode, the so-called power limit 1 (PL1), the system still allows the processor to go beyond the standard TDP power consumption of 125 W, but for a short time (on our system for about 50 seconds).

Next, the CPU voltage and frequencies drop, with power consumption limited to 125 W.

In the second power limit 2 (PL2) mode, the system will limit the power consumption to 250W.

What have we gained in practice?

When using the PL1 limit and loading all cores (Cinebench R20 multi-threading, rendering, AIDA64 stress tests), the frequency of all cores is kept at 4900 MHz, and the CPU voltage was 1.3 V.

After about 50 seconds, the operating voltage drops to 1.17 V, the frequencies of all cores decrease to approximately 4200-4300 MHz (depending on the application), and the processor starts to operate within the power consumption of 125 W.

AIDA64 stress test with all core load shows that the initial frequency of 4900 MHz drops to 4300 MHz after about 50 seconds (PL1 mode with power consumption limitation)

The 10900K reached 5100MHz at 1. 36V.

Collecting the statistics of operating frequencies during the operation of the system, we noticed that the values ​​\u200b\u200band 5300 MHz were fixed, but these were only rare short-term bursts.

Surprisingly, the 10-core i9-10900K proved to be very economical at idle and at low loads.

The frequencies drop to 800 MHz, the voltage drops to 0.79 V, and the power consumption, according to HWiNFO, was, at times, only 9 watts.

This is even less than what we recorded for the Intel Core i5-9400F.

As for overclocking, the manufacturer in the case of the Intel Core i9-10900K left almost no reserve.

At the same time, the processor itself has an unlocked multiplier, which, in general, makes it convenient to experiment with frequencies, but there is little sense.

Yes, you can get a very small increase in frequencies, but this will be accompanied by a noticeable increase in the already considerable power consumption.

400F was tested in normal mode without overclocking.

Intel Core i9-10900K also worked without overclocking, but for it we separately tested with factory power consumption limitation (Intel Core i9-10900K PL1) and without limitation (Intel Core i9-10900K PL2).

To ensure decent cooling of the Intel Core i9-10900K, a fairly advanced dropsy ASUS ROG Strix LC 240 RGB was used.

Please note that in games, at least in our set, the power consumption of the Intel Core i9-10900K does not go beyond the regular 125 W, so in the corresponding graphs in this case there is no separation between Intel Core i9-10900K PL1 and Intel Core i9-10900KPL2.

Both processors used Kingston HyperX FURY DDR4 RGB memory at 3200MHz (XMP enabled).

In games, performance is often limited not by the capabilities of the processors, but by the graphics card. To minimize this, we used the most powerful ASUS ROG Strix GeForce RTX 2080 Ti graphics adapter.

ASUS ROG Strix GeForce RTX 2080 Ti

Oddly enough, even such a graphics card will hold back overall gaming performance at high graphics settings.

The weaker the video card and the higher the resolution and graphics level, the lower the FPS level in games will depend on the processor.

Two modes were used in each game.

First, with 2K resolution (2560×1440 pixels) and high or maximum graphics settings.

And the second one with a resolution lowered to Full HD (1920 × 1080 pixels) and a medium or low level of graphics.

The gaps in the results with a lighter load should be larger. Let’s see…

The maximum difference between Intel Core I9-10900 K and Core I5-9400 F.

A good gap is also visible when archiving, converting video.

When it comes to games, with high quality graphics and 2K resolution , even such a powerful video adapter as i5-9400 F, but, anyway, this gap is percentages, tens of percents, but not times .

And the weaker the video card you use, the smaller the difference between the processors.

Of course, in the case of streaming games, the advantage of the i9-10900K, with its stock of cores, will already be significant.

By the way, the Core i5-9400F, which is still very widely sold, performed very well in games, even paired with the flagship RTX 2080 Ti graphics adapter.

Intel Core i9-10900K and Core i5-9400F

Even before the tests, it was clear that the Core i9-10900K would be much inferior to the Core i5-9400F in terms of performance and price. It’s not as fast as it is more expensive.
