AMD Ryzen 9 7900X3D Linux Performance

Written by Michael Larabel in Processors on 7 March 2023. Page 7 of 7. 51 Comments

As with the Ryzen 9 7950X3D review, there were 391 benchmarks ran across this assortment of Intel and AMD processors on Linux. Across the nearly 500 benchmarks ran, it was pretty much in the same technical areas where the 7900X3D performed the best like the 7950X3D with computational fluid dynamics, some renderers, and other select areas where the software can fully leverage the 128MB L3 cache. But even outside of those areas, the Ryzen 9 7900X3D and 7950X3D both were delivering excellent performance-per-Watt compared to the other AMD Ryzen 7000X series processors and the Intel Core i9 13900K Raptor Lake processor.

When taking the geometric mean of the 391 benchmarks run, the Ryzen 9 7900X3D was around 96% the performance of the Ryzen 9 7900X due to its higher boost clock, higher TDP, and not all of the workloads able to make effective use of the 3D V-Cache.

Where the Ryzen 9 7900X3D becomes very compelling like the 7950X3D was when factoring in the power efficiency. During the 391 benchmarks, the Ryzen 9 7900X3D was on average running at 76 Watts with a recorded peak of 120 Watts -- right inline with its reported 120W default TDP rating. Meanwhile the Ryzen 9 7900X had an average of 124 Watts with a peak of 236 Watts. The Ryzen 9 7900X3D was at 96% the performance of the 7900X while consuming just 61% the power on average. This is similar as well to the 7950X vs. 7950X3D outcome as well across the wide assortment of benchmarks.

Next up is the AMD Ryzen 7 7800X3D launching in one month and with its 8 cores / 16 threads all accessible to the 96MB L3 cache. Without any CCD differences to worry about, it will be very interesting to see how the Ryzen 7 7800X3D performs on Linux as a successor to the Ryzen 7 5800X3D.

Additional AMD Ryzen 9 7900X3D/7950X3D Linux benchmarks will be coming up on Phoronix soon looking at other areas where these desktop CPUs with 3D V-Cache Technology can be quite compelling in addition to the promoted gaming focus.
