Monero Hashrate kH/s

Monero has been using the RandomX algorithm since November 2019of the year. This PoW (proof of work) algorithm can only be computed efficiently using either a processor (CPU) or a graphics card (GPU). The CryptoNight algorithm was used for Monero until November 2019, but it could be calculated using ASICs. RandomX benefits from a large number of CPU cores, cache, and fast memory connectivity through as many memory channels as possible.

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.

Intel Core i9-10900K vs. Intel Core i5-9400F

Intel Platform 1

• Processor: Intel Core i9-10900K
• Motherboard: ASUS ROG Strix Z490-E Gaming
• Cooling: CBO ASUS ROG Strix LC 240 RGB
• : ASUS ROG Strix GeForce RTX 2080 Ti
• Operating System: Windows 10 Pro 64 bit (2004 Update)

Platform Intel 2

• Processor: Intel Core i5-9400f
• Maternal board: ASUS TUF Z390-PRO GAMING
• COOMS: FIR DDR4 3200MHz (Kingston HyperX FURY DDR4 RGB HX432C16FB3AK2/16)
• Video Card: ASUS ROG Strix GeForce RTX 2080 Ti
• Operating System: Windows 10 Pro 64bit (2004 Update)

Intel i05 9002 CPU

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.

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…
