Epyc Turin CPUs based on AMD Zen 5 will offer up to 256 cores and a 600W TDP

Today we learned from a rumor that AMD’s Zen 5-based Epyc Turin server processors will offer a huge leap in compute density with up to 256 cores and 512 threads. According to @ Greymon55, there are two configurations with gigantic computing capabilities, one is 192 cores with 384 threads and the other the one we just named 256 cores and 512 threads. By comparison, existing Milan EPYC CPUs max out at just 64 cores / 128 threads, and Genoa is programmed to have 96 cores and 192 threads.

It is said on the street that Bergamo will take advantage of a separate platform with up to 128 cores and 256 threads, but we haven’t heard much about this architecture. Either way, Turin will have a massive upgrade over existing Epyc platforms, offering 3-4 times more performance than Genoa and 5-6 times more than Milan. This will of course come at a cost and these monster processors are expected to have a 600W TDP.

Epyc Milan models exceed 300W TDP, so you have an idea of what is coming. Still, considering the huge increase in core counts, I’d say the efficiency is more or less maintained. Fourth generation AMD Epyc Genoa processors leveraging TSMC’s Zen 4 architecture and 5nm node are scheduled to land in late 2022.

This means that Turin and Zen 5 should arrive at the end of 2024 and should be based on the N3 manufacturing process, with this it should have an improvement in consumption and performance.
