Ah... so they are going to have to severely cut down on the frequency then. I was hoping for an incredibly high TDP like the FX-9590

180 Watt seems to be the upper limit with the present knowledge, the lower limit is 120 Watt though (for the 8-core/16-thread dual socket EPYC's).
But there's a dual socket capable, 32-core/64 thread EPYC with a TDP of 155 Watt too...155 Watt seemingly also the lower limit for the first generation of single-socket EPYC CPUs.

But be prepared to pay $4,000 for a 32-core...the dual socket capable 8-cores are just $400 though.

Mind you: the octo-channel RAM design dictates that you buy your (ECC) RAM in sets of eight sticks at a time.....for those of us with deeeep pockets.
