Threadripper may come close in core count, but it cannot use registered memory, which means it's limited to 128 GB of RAM (based on the current maximum UDIMM capacities). That's not competitive in the server space.

oops, you're right, good point

EYPC is their server line, which has a 32 core count cpu with RDIMM support.

Why does threadripper need to be competitive in the server space? Edit: emphasis on threadripper, which is a consumer product.

  The server market is like Formula One for chip makers. It is where there is enough money to really push the limits of the technology. Competing in such leagues brings institutional knowledge, and bragging rights. Servers is also where you get back-and-forth discussions with customers large enough to be worth listening to. Getting useful feedback from the users of desktop CPUs is difficult and time-consuming. But someone like Facebook or Google, who buy thousands of CPUs, and know how to use them, can give you quick and reliable feedback. They can test prototypes and suggest changes within weeks.

  Because laptop CPUs don't make any money, and gaming PCs are so small a market as to be irrelevant. The bulk of x86 revenue, and almost all the profit, is in the datacenter.

    Right. But threadripper isn’t AMD’s server processor, and EPYC is eating Intel’s lunch.

EPYC supports up to 2TB per CPU so it's not entirely uncompetitive... Not sure I trust Intel's figures here anyway - some people are saying it's less than the 3.84TB per socket... https://www.tweaktown.com/news/58052/amd-epyc-32c-64t-3-2ghz-2tb-ram-128-pcie-lanes/index.html https://www.tweaktown.com/news/58052/amd-epyc-32c-64t-3-2ghz...

Threadripper is not a server CPU, it's a HEDT CPU. Epyc is the server CPU line.
