AMD Ryzen Threadripper PRO 7985WX CPU Delivers Big Single & Multi-Threaded Gains Over 64-Core Zen 3 & Zen 2 Threadrippers

AMD's Ryzen Threadripper PRO CPUs are fast and the 64-Core 7985WX chip shows significant gains over its Zen 3 & Zen 2-based predecessors in the latest benchmarks.

The AMD Ryzen Threadripper PRO 7000 CPUs are a significant upgrade over the PRO 5000 chips. They get brand new Zen 4 cores, they get support for DDR5 and PCIe 5.0 hardware, they get a new platform (Storm Peak) and the core counts go all the way up to 96 with 192 threads to boast about. But, the lineup also has a 64-core model which can be compared directly against the older Zen 3 & Zen 2 64-core parts to see how much of a gain users can expect when upgrading to the new lineup with similar core counts.

Starting with the specifications, the AMD Ryzen Threadripper PRO 7985WX CPU features 64 cores based on the Zen 4 core architecture with 128 threads. The Chip has a base clock of 3.2 GHz and a boost clock of up to 5.1 GHz. The CPU also carries 256 MB of L3 cache, 64 MB of L2 cache, and 4 MB of L1 cache. The chip has a TDP of 350W and is fully unlocked for overclocking while supporting 8-channel DDR5-5200 memory.

The benchmarks of the chip appeared on Geekbench which were discovered by Benchleaks. The AMD Ryzen Threadripper PRO 7985WX 64-Core CPU was configured within a Dell Precision 7875 Tower with 256 GB of DDR5-5200 memory and the power plan is "Balanced". So you can expect the performance to be totally stock. The CPU actually boosted up to 5.3 GHz (5294 MHz to be exact) & that shows just how efficient chips Zen 4 Threadrippers could be even when supporting a huge amount of cores.

Coming to the scores themselves, the AMD Threadripper PRO 7985WX 64-Core CPU scored 2599 points in single-core and 24780 points in multi-core tests. For comparison, the older Zen 3-based Ryzen Threadripper PRO 5995WX scores 1993 points in single-core and 18205 points in multi-core tests. Even the Threadripper PRO 3995WX which is the 64-core Zen 2 model scores 1591 points in single-core and 15106 points in multi-core tests.

This marks a single-threaded improvement of 30% & 63% over the 5995WX & 3995WX, respectively while the multi-threaded improvement is rated at 36% & 64% over the 5995WX & 3995WX. This is a huge gain and for those looking for even better multi-threading capabilities, the AMD Threadripper PRO 7000 lineup completely delivers on that promise.

The Threadripper PRO 7995WX CPU was also tested and ended up with a higher single-core score of 2673 points but the multi-core 25147 score is a little underwhelming which could be due to the limitations of the benchmark itself since there are 96 cores we are talking about.

This goes off to show AMD's commitment to pushing the enthusiast workstation landscape despite there being little to no competition. Intel has its Xeon W-3400/2400 CPUs out for a while but they are simply no match to the higher core counts, higher efficiency, and the expanded I/O offered by the Threadripper portfolio.
