AMD Ryzen 7 7800X3D Linux Performance

Where much of my Ryzen 7 7800X3D time thus far has been spent is exploring the performance in other Linux workloads across a variety of fields and areas of interest.

For workloads like the LC0 chess engine that benefit from the 3D V-Cache, the Ryzen 7 7800X3D was midway between the 7700X and 7900X performance as expected. The four additional cores of the 7900X were more useful for LeelaChessZero than the extra cache. Generationally there was huge uplift here with a 43% improvement going from the 5800X3D to 7800X3D.

The Ryzen 7 7800X3D proved to be particularly compelling when it came to the power consumption and power efficiency with it far surpassing the other tested AMD and Intel processors.

In the case of the CloverLeaf hydrodynamics benchmark, the large L3 cache size played enough of a role that the 7800X3D outperformed not only the Core i9 13900K but also the Ryzen 9 7900X and 7950X processors.

All while the Ryzen 7 7800X3D was running at under its 120 Watt default TDP.

Most commonly though the Ryzen 7 7800X3D was positioning itself in these workloads right between the 7700X and 7900X.

Incompact3D was another one of the technical computing workloads where the AMD 3D V-Cache makes enough an impact to put the 7800X3D competing with the 7900X/7950X processors.

The OpenFOAM open-source computational fluid dynamics (CFD) software is one of the more popular real-world uses that benefit a lot from AMD 3D V-Cache. With OpenFOAM 10's benchmark the Ryzen 7 7800X3D comes out between the 7900X and 7950X performance!

But making the 7800X3D results for OpenFOAM CFD all the more impressive is the much lower power consumption rate -- less than half the power consumption rate of the Ryzen 9 7950X and less than a third of the Core i9 13900K.
