Yeah, its the same as EPYC Genoa. Theoretically they could pack in 192 cores with the 16-core die, but haven't done so (on EPYC) for reasons unknown to me. May

Yeah, its the same as EPYC Genoa.
Theoretically they could pack in 192 cores with the 16-core die, but haven't done so (on EPYC) for reasons unknown to me. Maybe a physical packaging limitation?
- zen_1 3y agoProbably thermals, at ~3W/core TDP, 192 cores is gettingg close to 600W to dissipate from a single socket, which is beyond all off the normal heatsink/watercooling solutions I'm aware of
- brucethemoose2 3y agoYeah, that it plausible, though it seems like they could just run the cores a little slower.
- Tostino 3y agoThere are some pretty interesting cooling solutions in development. Will be interesting to see which ones become economical enough for mass market use.
- automatic6131 3y agoThat's Zen 4c, which I don't think is ready yet? I'm pretty sure 192c/384t* at ~4Ghz EPYC is on the way, although that might be a Zen 5c product (so... 2025, 26?) *wow, core counts so big I found it slightly difficult to multiply by 2 in my head.
- brucethemoose2 3y agoIts Bergamo, which tops out at 128C (8 dies) and supposedly is already available to cloud companies.
