AMD has issued a new advisory regarding the performance characteristics of its new Ryzen 7000 processors. Despite reports of unexpected performance deltas in some games, as experienced first-hand in tests using a Ryzen 7000 processor and his Nvidia GeForce RTX 4090, AMD said: . We haven’t seen anything unexpected and will work with game developers to optimize the new architecture.

Additionally, despite unsubstantiated reports of Windows 11 performance issues, the company hasn’t seen any unexpected results comparing Windows 10 and Windows 11.

This advisory reflects what the company told us after sharing its own results that revealed some performance reversals on Ryzen 7000 processors. These flips over the dual CCD model happened in 3 of the 8 game titles we tested with the new RTX 4090 GPU. warhammer 3, Cyberpunk 2077When F1 2022We’re also hearing about similar trends of lift breaker When Metro Exodus.

In the slide above we can see that the dual CCD Ryzen 9 7950X and Ryzen 9 7900X sometimes underperform the single CCD Ryzen 5 7600X and Ryzen 7 7700X. F1 2022 RTX 3090 (two other titles are new to the CPU test suite).

I previously tested with Windows 11, but updated to Asus RTX 4090 ROG Strix OC and GPU drivers along with the latest Ryzen 7000 BIOS and chipset drivers for a new round of testing that revealed the issue.

After contacting both AMD and Nvidia about the issue, AMD said this could be unoptimized game code, which was revealed by the RTX 4090’s massive increase in GPU horsepower. said to be sexual. As AMD’s full statement below reiterates, these differences are not completely unexpected with the new architecture, as seen in our own tests above. However, AMD is conducting further testing and working with game developers to patch any titles that may be adversely affected.

Several factors may be involved. Some games just prefer fewer cores and threads, and AMD’s secondary CCD on any dual his chiplet CPU also tends to run at slightly lower clock speeds. In either case, these effects can usually be mitigated through game code optimization.

Additionally, test results posted by CapFrameXis a popular benchmarking tool on Twitter where users don’t seem to post Windows 10 and Windows 11 benchmarks, but often misleadingly attribute the issue to Windows 11. It caused a wave of reports in the media. AMD’s latest advisory throws cold water on these claims, pointing out that independent testing has uncovered no unexpected issues with Windows 11.

Yes, AMD processors and Windows 11 had some early performance teething pains, but as our own testing shows, those issues were resolved last year. According to AMD, there are no new issues with Windows 11 and Ryzen processors. Here’s AMD’s full statement:
