AMD with a statement about unexpected performance deviations

AMD with a statement about unexpected performance deviations

of Valentin Sattler
AMD has released a statement that it is currently investigating reports of unexpected levels of Ryzen performance for gaming. The operating system used was often assumed to be the cause, but AMD has not been able to identify any anomalies so far. Instead, AMD wants to try and get software patches for the respective games.

With the new Ryzen 7000 processors, AMD offers significantly more computing power than with the previous generation: the performance per core has increased significantly, which should also please gamers in particular. As with previous generations of Ryzen, the performance of games within the Ryzen portfolio is apparently not always consistent. The background is the internal structure: while the Ryzen 9 7950X and Ryzen 7 7900X use two internally powered chiplets, the Ryzen 7 7700X and Ryzen 7 7600X perform calculations within a single chiplet.

Known issues, known solutions

In some games it can now happen that really slow CPUs with a single chiplet compute faster than better models with two chiplets. Especially when AMD first used the chiplet approach, this was a problem that required various software patches so that programmers could distribute the computing load in the best possible way. With Ryzen 7000 there is apparently a step backwards here, so the situation reoccurs. For example, the new Ryzen CPUs with one CCD were faster than models with two chiplets in Tom’s hardware test across titles Warhammer 3, Cyberpunk 2077, and F1 2022.

AMD has now responded to such reports with a statement. Consequently, the company has received several indications of such performance deviations, which are currently being investigated. An OS influence is apparently ruled out, as it used to be: the situation occurs in both Windows 10 and Windows 11, and an OS patch is apparently not planned.

Instead, according to the statement, AMD wants to work with the developers of the affected games to iron out unexpected performance differences. As with previous generations, patches will be developed for individual games that improve distribution between the two Ryzen 7000 CPU chiplets. Unfortunately, AMD’s text does not indicate when and for which games the corresponding patches will be released. At least the point of the updates should be clear: when in doubt, games should use the faster chiplet and minimize the communication required between the two chiplets.
