96 cores? Have they packed 12 (8-Core) CCDs into this? That's insane.

96 cores? Have they packed 12 (8-Core) CCDs into this? That's insane.
- brucethemoose2 3y agoYeah, 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.
