Geekbench 4.2.3

Starting off with a single-threaded synthetic benchmark, we see gains of about 6% generationally from the 1950X to the 2950X.

Ultimately, the new Threadripper CPUs fall about 2% behind the Ryzen 7 2700X in single-threaded performance. Likewise, there is an over 6% performance gap between the new Threadripper CPUs and Intel's Skylake-X CPUs.

In Geekbench's multi-threaded test, we see some unexpected results. It appears that the benchmark has issues handling massive amounts of threads, like the 64 found in the 2900WX, making the 16-core 2950X score higher in comparison.


This fluid dynamics simulation is very CPU and memory intensive.  From the benchmark source website:

"The benchmark test case is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45-degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes. Figure 1 shows the CFD predicted Mach contours for a freestream Mach number of 0.960.

The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. Our benchmark score is reported as a CFD cycle frequency in Hertz."

Similarly, despite the thread count advantage, the 2990WX falls short to the 2950X in the Euler3D benchmark. This performance issue is likely due to the 4 NUMA node configuration of the 2900WX, versus the unified memory configuration of the 2950X.

However, the Skylake-X processors far and away take the performance crown, with up to double the score of the 2950X in the 32T test.

7-Zip Compression

Compression in 7-Zip sees similar results at the previous test, where the 2990WX simply doesn't seem to performance scale above 24T, and the Skylake-X processors outperform the Threadripper 2950X.
