AMD Ryzen 9 9950X Gaming Performance — The TLDR 

Intel has released new microcode to address instability issues with its 13th and 14th Gen processors. We’ve retested the Intel chips with the new microcode and used the company’s highest recommended power limits within the new guidelines. Intel’s gaming results are higher in this review than we recorded with the restrictive power guidelines imposed before the patch arrived, but those improvements stem from moving to a higher power limit and not from the microcode update.

We encountered more variability in our Ryzen 9 9950X and 9900X gaming tests than we’re accustomed to, and we think an issue we identified with the core parking tech could contribute to the inconsistent results. See our test setup page for more details, but in addition to our results below, you should check multiple reviews to get a broader view of gaming results. We’re re-validating our Zen 5 gaming results and will update as necessary.

Below, you can see the geometric mean of our gaming tests at 1080p and 1440p, with each resolution split into its own separate chart. We tested with an Nvidia GeForce RTX 4090 to reduce GPU-imposed bottlenecks as much as possible. Still, differences between test subjects will shrink with less powerful cards or higher resolutions. We removed the Watch Dogs Legion benchmark from our suite for the time being — the benchmark is now delivering odd results with Intel processors that aren’t reflective of our prior testing. As such, these cumulative results are different than those seen in our Ryzen 5 9600X review. You'll find game-by-game breakdowns further below.

    Your story mentioned the USB 4.0 60GB/s with 3rd party chips, is that a new feature? its 40GB/s and then the newest standard of Thunderbolt is 80/80 (or 120 if you change one of the channels to make it asymetrical). There is no such thing as 60

    And pretty much like every other enthusiest on here, I think th is is the most disapointing AMD launch...ever

    Good eye. Typo, fixed!

    While this isn't like 6 generations of skylake, it sure feels a bit like it. This is why we need a competitive product from both companies in both performance and power

    It gets so confusing when the performance of new products falls between products from the past generation. Just make one chip with a true generational difference and charge $600.

    Very disappointing the single thread and gaming results. Anyway I find suspicious results on some benchmarks.

    There are regressions respect 7950X in games like "Far Cry 6" and "Hitman 3".

    Regression also in Outlook score vs 7950X.

    I found abnormal also the NAMD score that for the 9950X is 0.6328 days/ns while Phoronix achieved a 3.14 ns/day that is about twice the performance, for comparision the 14900k is in line with Phoronix.

    I suspect there is something to analyse and refine on these benchmarks.

    Agree that the driver problem with core parking feature is something unacceptable. But the need to reinstall the OS seems to me something exaggerated, must exist a better solution.

    Also is historical the surpass in Adobe benchmarks.

    Thanks for the review.

    There is obviously something fishy with Windows when you look at the results on Linux.

    "The Ryzen 9 9950X was 33% faster than the Intel Core i9 14900K performance overall and even the Ryzen 9 9900X was 18% faster than the Core i9 14900K. For those still on AM4, the Ryzen 9 9950X was delivering 1.87x the performance of the Ryzen 9 5950X processor. These are some great gains found with the Ryzen 9 9900 series."

    Anyone know if Zen 5 will allow for a mclk/uclk 1:1 with DDR5-6400 RAM or will that max out at 6000 again?

    Whilst it maybe disappointing for some, it simply appears that AMD are continuing to separate out their gaming CPU range from their productivity range.

    This appears to be a very powerful and efficient chip for multi core workloads that will likely get better when some of the usual teething problems are ironed out.

    Nothing groundbreaking, just a bit better.
