AMD has issued a brand new advisory relating to the efficiency traits of its new Ryzen 7000 processors, saying that regardless of reviews of sudden efficiency deltas in some video games — as we skilled firsthand in our testing with the Ryzen 7000 processors and the Nvidia GeForce RTX 4090 — the corporate hasn’t seen something sudden and can work with sport devs to optimize for its new structure.

Moreover, regardless of unsubstantiated reviews of efficiency issues with Home windows 11, the corporate hasn’t seen any sudden outcomes when evaluating Home windows 10 and Home windows 11. 

The advisory mirrors what the corporate advised us after we shared our personal outcomes that uncovered just a few efficiency inversions with the Ryzen 7000 processors. These inversions, whereby single-CCD (chiplet) Ryzen fashions outperformed dual-CCD fashions, occurred in three of the eight sport titles we examined with the brand new RTX 4090 GPUs: Warhammer 3Cyberpunk 2077, and F1 2022. We have additionally heard of comparable developments with The Riftbreaker and Metro Exodus.

Within the slides above, we will see that the dual-CCD Ryzen 9 7950X and Ryzen 9 7900X at instances underperform the single-CCD Ryzen 5 7600X and Ryzen 7 7700X, which wasn’t the case in our unique spherical of checks with F1 2022 the RTX 3090 (the opposite two titles are new to our CPU check suite).

We had beforehand examined with Home windows 11, however up to date to the Asus RTX 4090 ROG Strix OC and GPU driver, together with the most recent Ryzen 7000 BIOS and chipset drivers, for our new spherical of testing that uncovered the difficulty.

We contacted each AMD and Nvidia in regards to the matter, and AMD advised us that this may very well be unoptimized sport code that has now been uncovered by the massive leap in GPU horsepower with the RTX 4090. Nvidia has but to reply to our question. As AMD’s full assertion under reiterates, these variances, as we have seen in our personal testing above, aren’t fully sudden with new architectures. Nevertheless, AMD is following up with additional testing and can work with sport devs to patch any titles that is perhaps adversely impacted.

A number of components may very well be at play. Some video games merely want fewer cores and threads, and AMD’s secondary CCD on any given dual-chiplet CPU additionally tends to run at barely decrease clock speeds. In both case, these results can usually be mitigated with sport code optimizations.

Moreover, check outcomes posted by CapFrameX, a preferred benchmarker on Twitter, prompted a wave of deceptive reviews within the media that always attributed the difficulty to Home windows 11 — though it would not seem that the consumer even posted Home windows 10 vs Home windows 11 benchmarks. AMD’s newest advisory pours chilly water on these claims, noting that its personal testing has not uncovered any sudden points with Home windows 11.

Sure, there have been preliminary efficiency teething pains with AMD processors and Home windows 11, however as our personal testing has proven, these points have been addressed final yr. In response to AMD, there are not any new points with Home windows 11 and Ryzen processors. AMD’s full assertion follows:
