\"i9-10900K
\n
\nA little over a year has passed since I tested the brand new Intel Core i9-9900K<\/a><\/noindex>. But time passes, everything changes, and Intel has already released the fresh line of 10th generation processors, the Intel Core i9-10900K. What surprises do these processors hold for us, and is everything really changing \u2014 let's talk about it right now.
\n<\/a><\/noindex><\/p>\n

Comet Lake-S <\/h3>\n

\nThe codename for the 10th generation Intel Core processors is Comet Lake. And yes, it's still 14 nm. Yet another refresh of Skylake<\/a><\/noindex>, which Intel themselves refer to as an 'evolution'. That\u2019s their prerogative. Let them call it what they want. For now, let's take a look at what has changed in the new generation compared to the previous, the ninth. And we'll find out how far the i9-10900K has moved away from the i9-9900K. So, let's get started. <\/p>\n

Socket change<\/b><\/p>\n

The LGA 1151 socket<\/a><\/noindex> (Socket H4) was designed in 2015 and lasted a full 5 years, having seen as many as four generations of processors, which is generally unusual for Intel, a company that likes to change sockets every two years. However, it's worth noting that the company compensated for this somewhat with incompatibility between new\/old processors and chipsets...<\/p>\n

Yes, nothing lasts forever under the moon, and Intel, alongside the release of the 10th generation, introduced a new socket \u2014 LGA 1200 (Socket H5). Although it is compatible with the mounting holes (75 mm) of existing cooling systems, the faint hope that they wouldn't need to be replaced disappeared after the first preliminary tests. But more on that later. <\/p>\n

More cores, higher frequency<\/b><\/p>\n

Already a traditional Intel solution when it comes to nanometers: if you don't change the technology process<\/a><\/noindex>, then add cores and increase the frequencies. It worked again this time.
\nThe Intel i9-10900K processor got two additional cores, accordingly, 4 threads in Hyper-threading<\/a><\/noindex> (HT). As a result, the total number of cores increased to 10, while the number of threads rose to 20. <\/p>\n

Since the technology process hasn't changed, the heat removal requirements, or TDP<\/a><\/noindex>, increased from 95W to 125W \u2014 that\u2019s more than a 30% increase. I remind you that these figures are when all cores are running at base frequency. Cooling this 'heat monster' with air is rather challenging. It\u2019s advisable to use a liquid cooling system (LCS). However, there\u2019s a catch. <\/p>\n

If the base frequency of the new processor has only risen by 100 MHz \u2014 from 3.6 to 3.7, then with Turbo Boost<\/a><\/noindex> It has become more interesting. If you remember, the i9-9900K in Turbo Boost can reach 5 GHz on one core (rarely on two), 4.8 GHz on two, while the remaining cores operate at a frequency of 4.7 GHz. In the case of the i9-10900K, one core now operates at 5.1-5.2 GHz, and all others at 4.7 GHz. But Intel didn't stop there. <\/p>\n

In addition to the already familiar Turbo Boost technology, a mega super turbo boost has been introduced. Officially, it is called Thermal Velocity Boost (TVB)<\/b>. It should be noted that this technology was implemented back in the eighth generation of Intel Core, but only a select few got access to it. For example, I personally know of the i9-9980HK and i9-9880H. <\/p>\n

The essence of the technology lies in the fact that at a certain processor temperature, the frequency of one or more cores rises above Turbo Boost. The added frequency depends on how much the operating temperature of the processor is below the maximum. The maximum frequency of the processor cores with Intel Thermal Velocity Boost enabled is achieved at an operating temperature not exceeding 50\u00b0C. As a result, in TVB mode, the clock frequency of one core rises to 5.3 GHz, while the other cores increase to 4.9 GHz. <\/p>\n

Since the new generation has two more cores, at maximum auto-overclocking with all types of boosts, this \"kettle\" can draw up to 250 W, which is already a challenge even for a water cooling system (WCS), especially in a compact case without external water blocks... <\/p>\n

Having discussed the cores, explained the frequencies, and lamented the socket, let's move on. Among the main changes, we can add a slightly increased L3 cache and a higher frequency of supported RAM \u2014 from DDR-2666 to DDR4-2933. That's about it. Intel hasn't updated the integrated graphics core either. The RAM capacity also remains unchanged; the same 128 GB has been inherited from the previous generation. So, as always with refreshes: they added cores and frequencies, but also changed the socket. There are no other significant changes, at least in the context of servers. I suggest we move on to testing and see how the performance of the new generation has changed compared to the previous one. <\/p>\n
