Threadripper PRO 7985WX with 64 cores

The face-off of AMD Threadripper CPUs shows Zen4 as a clear winner.

AMD unveiled its Threadripper 7000 series last week, with the actual product launch slated for about a month from now. Interestingly, AMD’s communication about the review embargo appears to have been quite unclear to its partners. Consequently, numerous websites wasted no time in sharing their testing results on the day of the Zen4 Threadripper announcement. Most of these tests were conducted on Dell Precision 7875 Tower systems.

The coverage, however, was somewhat lacking in information regarding models with 64 cores or fewer. The initial testing predominantly centered on the flagship 96-core TR 7995WX model. Nevertheless, with more data on the 64-core variant, one can get a more in-depth understanding of how much better is the newer platform compared to Zen3 TR, which was offered with up to 64-cores as well.

It appears that someone has already conducted an initial test featuring the TR 7985WX processor, which boasts 64 cores, and the results are quite promising. This test showcases the Threadripper PRO 7985WX processor with a base clock of 3.2 GHz and a boost clock of up to 5.1 GHz. As pointed out by Tom’s Hardware, this represents an 18.5% improvement in the base clock and a 13.3% higher boost clock compared to the previous-generation Ryzen Threadripper PRO 5995WX. Notably, there have been changes to the L2 cache, which has doubled in size on the Zen4 architecture, and the TDP has also increased, now reaching 350W.

Furthermore, there have been platform changes, including the addition of DDR5 memory support. This alone can have a significant impact on synthetic benchmark results, as seen in official Geekbench rankings comparing the AMD Zen3 and Zen2-based Threadripper series, all featuring the same 64-core configuration. According to these results, the new CPU exhibits a 30% to 36% improvement in single-core and multicore tests over Zen3 5995WX, and it’s 63% to 64% faster compared to the Zen2 3995WX version. These gains are indeed quite substantial.

The Threadripper 7000 series is set to hit the market on November 21st. For enthusiasts, there will be an option to select non-PRO variants tailored for the HEDT (High-End Desktop) market. However, the 64-core version, known as the 7980X, comes with a price tag of $4,999, which may seem quite steep for a consumer processor. Nevertheless, it’s notably more affordable than the $7,394 price tag attached to the PRO variant.
