There’s been a rumor going about this 7 days about a new, 64-core Threadripper CPU from AMD. Dubbed the 3995WX and debuting beneath the “Threadripper Pro” brand name-name, this chip is supposed to debut with an eight-channel memory configuration with assistance for up to 2TB of RAM.

Up till now, the chip has just been a rumor, but a the latest photograph of the core popped up on Chiphell, pointing to a definite introduction/launch at some level. The impression has considering the fact that been taken out, but hat-tip to Guru3D for surfacing the information.

I’ve used a large amount of time with the Threadripper 3990X in a variety of evaluations. The 3990X only delivers one memory channel for every 16 cores. Its huge L3 caches do an admirable position keeping the core fed, but there are specific memory bandwidth-sensitive programs that do not scale up perfectly on the 3990X. Since the CPU operates into other concerns associated to Microsoft Home windows and its assistance for processors with a lot more than 64 cores, these bandwidth constraints do not appear to be the basic principle bottleneck for the chip. But in the assessments where by they appear, they drag on performance.

A Ryzen Threadripper Professional 3995WX with 8-channel RAM assistance would reduce this constraint, with 2x the full RAM bandwidth. We do not have any other facts on the CPU, but we’d hope the clocks to be equivalent to the 3990X unless of course AMD’s upcoming 8-channel memory system also amplified the CPU electricity draw. The 3990X is limited to 280W nominally, however that can be exceeded to fantastic influence. Our overclocking examination effects showed that the 3990X experienced a large amount of headroom and benefited from even modest total-core overclocking.

I would not hope the 3995WX to be a significantly economical processor, and it is not going to be a significantly performant chip both exterior of unique workloads. The 3990WX is an absolute beast when deployed in an powerful configuration — I’ve in fact utilized it for dealing with several simultaneous examination encodes in my DS9UP (DS9 Upscale Task) to amazing influence — but AMD has specifically positioned it as a rendering and workstation core because the programs that gain from it the most are all those that implement their very own schedulers different from the default Home windows scheduler.

How AMD positions this chip will convey to us a little something about how the company’s efforts to unseat Intel in skilled marketplaces are coming along. Intel has reduced costs on the two its HEDT and its Xeon processors in excess of the earlier year to compete a lot more properly towards AMD’s Threadripper and Epyc items. It is unclear how or if AMD will section this system to maintain it different from Epyc, but AMD segments much less of its products attributes than Intel does in the initially place. The variations may well be slight.
