Here is a look at the CPU power consumption across the range of workloads tested for this article where these 7900X3D/7950X3D processors proved useful for these scientific workloads from hydyodynamics and computational fluid dynamics to AI. The 7900X3D on average was using just 62% the power of the 7900X while the 7950X3D on average was running at 61% the power of the 7950X.

The reduced power use of the Zen 4 X3D processors also led to lower temperatures for this Corsair water cooled setup.

Geometric Mean Of All Test Results benchmark with settings of Result Composite, Ryzen 9 7900X3D   Ryzen 9 7950X3D Linux Benchmarks. Ryzen 9 7950X3D was the fastest.

When taking the geometric mean for this set of Linux workloads that are able to effectively make use of the large 3D V-Cache, the 7950X3D was 18.5% faster than the 7950X! And then making it incredibly compelling is the above metric that it was so much faster while consuming just 61% the power! The Ryzen 9 7950X3D pricing is fair at around 16% higher than the 7950X. The Ryzen 9 7900X3D came out equally well with 14% better performance than the 7900X (or 8% faster than the 7950X in these workloads) while again doing so at much less power.

For those spending significant portions of your time working with OpenFOAM CFD, ClickHouse databases, hydryodynamics software packages, some AI software and models, and other workloads covered in this article, these 7900X3D and 7950X3D processors can be very compelling both for the better raw performance and power efficiency. Of course, for running heavy CFD simulations and the like there is obviously the AMD EPYC server processors, but for those on a budget or working on these open-source projects just as a hobbyist, the AMD Ryzen Zen 4 3D V-Cache processors are excellent options. These Ryzen 9 7900X3D/7950X3D results make me all the more excited for the upcoming AMD EPYC Genoa-X processors as well as the lower-end Ryzen 7 7800X3D processor. AMD 3D V-Cache paired with AVX-512 on Zen 4 is a great combination for many areas outside of gaming.

See my earlier 7900X3D review and 7950X3D review for all the Linux gaming benchmarks and the nearly 400 other benchmarks tested in full on these processors. I'm continuing to poke at the 7900X3D/7950X3D with additional workloads and Linux options so stay tuned, especially once seeing the potential of these processors with any Linux scheduler optimizations.
