In a statement released on Monday, AMD denied claims that its Ryzen 7000-series “Zen 4” desktop processors saw performance differences when gaming on Windows 11 and Windows 10 operating systems. The manufacturer claims that, although looking into the reports, it has not been able to duplicate these performance differences and insists that Ryzen 7000 series processors ought to operate equally well under both operating systems. The only architectural distinction between “Zen 4” and “Zen 3” is that “Zen 4” now supports the AVX-512 ISA, which even Windows 10 can run. Since Ryzen 5000 “Vermeer” and “Zen 4” multi-core topologies are identical, Windows 10 is aware of them. According to AMD, it is still working with game designers to make sure their products are optimized for Ryzen processors.

The following is AMD’s statement on the subject.

We have been made aware of reports of unexpected performance deltas in certain games with AMD Ryzen desktop processors as well as performance variances between Windows 11 and Windows 10 in certain game titles. We are currently investigating but based on testing to date have not observed a material difference in game performance between OS versions across a variety of operating scenarios and game titles.

Many factors affect gaming performance, including the game engine, CPU architecture, GPU selection and memory choices. As new architectures enter the market, we often observe performance anomalies which must be addressed by the component vendor or the game publisher. This is not a new phenomenon nor is it unexpected.

As we have done since the introduction of Ryzen, when these performance anomalies are brought to light we will use them to steer our partner engagements with game developers and ecosystem hardware partners to implement optimizations that eliminate the variations.
