Definitely an important factor, didn't check the max RAM. Kind of surprises me that AMD would put all this work into building a many core/thread CPU only to have a 256 GB RAM limit but if it's intended for gamers/workstations and not servers then I guess 256 GB would be plenty for that. But I agree it's unbalanced regardless.

That's the market -- EPYC is the server oriented product, and it supports a lot more RAM, though I think still less than Intel (I hand-wavily remember 4TB for EPYC, 6TB for Xeon, but with a huge price difference between them).

Given the design of threadripper, it's not really "all this work" to make a 64 core model, given the 32 core model. Just pile more of the things you can scale on the chip without worrying too much about the parts that don't scale. And the same happened with previous generation. 16 core 2950X turned into 2990WX, but with a weird crippled memory interface. At least 3990X is more balanced than that.

Threadripper is the prosumer chip, Epyc is the server chip. The current Epyc based on the 7nm Zen2 architecture can handle 4TB of ram.
