A week ago we looked at the slightly underwhelming AMD Ryzen 9600X and 9700X, which were marked by modest gaming performance increases in some titles, more significantly better content creation grunt and slightly better thermals. Now it’s time to look at the second half of AMD’s Zen 5 quartet, the £459/$499 Ryzen 9 9900X and £609/$649 Ryzen 9 9950X. These are powerful 12-core and 16-core parts that ought to be more of interest to content creators than gamers, so do they make a better case for Ryzen 9000? And does either one manage to exceed the top-level gaming performance of the 7800X3D?
Unfortunately, after four days of frantic benchmarking and troubleshooting, I’m not sure AMD has succeeded on either of these points. Our Ryzen 9900X and 9950X testing has been marked by confusingly poor gaming performance, including performance regressions versus the 7900X and 7950X, alongside a few examples of genuine uplifts that nonetheless don’t go far enough to making these CPUs worth recommending.
This review does at least mark the debut of two improvements to our benchmarking suite compared to last week’s reviews, which itself marked the introduction of an entirely new automated benchmarking system for Digital Foundry – and therefore only included a more limited selection of games than we’ve offered in the past.
