The release of Intel Raptor Lake processors also coincided somewhat with the release of the latest update for Windows 10, the 22H2. We write this in this context because it (22H2) quietly removes the most significant performance shortcomings, and the difference to the detriment of the older builds can be as much as 57 %. Most of the time this update doesn\u2019t change performance too much, but when it does, it changes it greatly.<\/p>\n

We’ve devoted quite a bit of text to the issue of Windows 10\/11 in the context of big.LITTLE processor testing in the introductory chapter of the standard Intel Core i9-13900K tests<\/a>. One of the reasons why the analysis of this processor did not come out on the day of its release was that we were struggling to make the results as relevant as possible compared to other processors. And it wasn’t the least bit easy.<\/p>\n

With the W10 21H2 version in some cases the performance was well below expectations. But at that time, the 22H2 update finally came out, and those who tested Raptor Lake under Windows 10 OS and also had tests on the 20th of October had virtually no chance to react to this. In such cases, Raptor Lake processors could have been at a significant disadvantage not only compared to competing processors, but also compared to the Core i9-12900K. We haven’t seen many such situations, but they do occur, especially in games.<\/p>\n

Gaming tests<\/h2>\n

There is a very significant difference in performance in CS:GO. In terms of average fps, possibly as much as 57 % to the detriment of the 21H2 OS version. Interestingly, Alder Lake (Ci9-12900K) works well with it and performance is as expected, only just below Core i9-13900K (with W10 22H2)<\/a>. Then there is a big difference in DOOM Eternal, and in the other games we tested, it wasn’t so dramatic. The difference was usually around 1 %. At higher resolutions with higher graphical details (with which the demands on calculating call draws also increase), the Core i9-13900K on our test setup with W10 22H2 is 6 % faster in one more game, F1 2020.<\/p>\n
