the benchmarks of the new Core i9-9900K were deceptive

This week Intel introduced its new 9th generation Intel Core processors for desktops, and the bet was clear: enhance gaming. This launching has generated a great controversy, because the results of the official tests that compared the Core i9-9900K with the AMD Ryzen 7 2700X had been realized in conditions of disadvantage for the AMD microphones .

It's not really Intel who has done those tests, which they commissioned from a specialized company called Principled Technologies. The data pointed to the new Intel microphones were “up to 50% faster in video games than the Ryzen”, but the claim is exaggerated, since in those tests AMD Ryzen were configured so that their performance is I was hurt . The company has admitted the error and will redo the tests, but the damage is done.

Tests on unequal conditions

When performing the Principled Technologies tests, it started with an unfair comparison since it faced the AMD Ryzen 7 2700X that costs 319 dollars with the Intel Core i9-9900K that will cost 530 dollars (in lots of 1,000 units).

Esa comparison of processors in different price ranges has actually been a first criticism of a process that has been seen punctuated by questionable decisions namely:

  • Ventilation : they used the Ryzen series fan, while they took advantage of a more advanced Noctua fan (NG-U14S) to Cooling the Core i9-9900K, something that could significantly impact the results of tests that demand a lot from these processors and that in doing so cause good cooling solutions to be needed. The company explained how the idea was to use the same Noctua NH-U14S for AMD, but since they were not going to overclocking these microphones and “AMD says” that their fan is a good fan, “we kept the Wraith Prism fan native to the AMD Ryzen 7 2700X. “
  • Layered cores : AMD has an option called” Game Mode “that disables half of the cores to improve game performance of Threadrupper processors, but is not designed for gamers. Ryzen Even so, the firm activated this mode and caused that the processor with 8 cores could only use four. That prevents certain games and benchmarks that do take advantage of those extra cores again favor the Intel micro, which worked at all times with all its active cores.
  • Memory : in Principled Technologies configured the machine based on the AMD Ryzen taking advantage of four memory modules that damaged the support of the dual-channel memory controllers of these processors. It is much more convenient to use only two modules to make the most of that support, and the four modules did not help to improve the tests. As explained in TechPowerUp that configuration also causes the working frequencies of the memories to be limited even though the modules used were 2933 MHz.
  • Resolution : has also been criticized the resolution of 1,920×1,080 pixels chosen for the tests. In Principled Technologies argue that the decision was focused on testing the performance of CPUs and not divert work to GPUs, in addition to indicating that according to data from Steam, more than 60% of users play at this resolution. However, a processor in which one spends more than 500 dollars is probably not oriented to a team to play in 1080p, and critics demanded evidence to other resolutions.

The managers of Principled Technologies have responded to criticism ] with an explanation of the decisions made (some of which we have already mentioned), but have committed to correcting some of the parameters they chose in the original tests for to retest and publish new results .

 Intel3

For its part, in Intel have issued a brief statement indicating that the results of the tests were consistent with what Intel itself observed in its internal benchmarks, although they also point to review of the evidence and especially to future independent analyzes:

We deeply appreciate the work of the analyst community and we hope that in the next few weeks additional tests will continue to show that the Intel® Core i9-9900K 9th generation processor is the best gaming processor in the world. Principled Technologies carried out this initial test using systems that run according to specifications, configured to show the performance of the CPU and published the configurations used. The data is consistent with what we have seen in our laboratories, and we hope to see the results of additional third-party testing in the coming weeks.

It remains to be seen what the revised test results are for Principled Technologies, but above all, it will be interesting to see in specialized media analysis how the new 9th generation Intel Core processors come to a halt.
