AMD promises that Zen 3 "Milan" processors will be socket compatible with Zen 2 EPYC

Milan targets a mid-2020 release date.



Read more about AMD's EPYC server plans.

Wonder if that means we could have Zen 3 architecture be compatible with AM4 socket.

Should be. I don't see DDR5 taking off before this time next year. New memory types usually start at the high end and trickle down. I think DDR4 started with X99.

Yeah AMD did say 2020 explicitly for new product support assuming the consumer launches are also set for mid-2020 like this. TSMC's 7nm+ has a stated improvement of 10% performance or 15% power efficiency improvements so will probably translate to a couple MHz extra on the top end and low idle state consumption, but the key benefits would probably be from the maturity of the node and the use of EUV in non critical areas improving yields and making a wider uarch/+more cache viable economically.

TSMC improvements are recorded for very simple circuits. Which is what Lisa Su stated. You don't get the same benefits on larger complex architectures.

Yeah that's why I said a couple hundred Mhz rather than the >400MHz a straight 10% gain would deliver. The first TSMC 7nm+ device will be the Huawei(HiSilicon) Kirin 985 SoC launching quite soon and they're expecting about 20% gains over the 980 (Apple A13 expected around the same time but they usually come with big arch & layout changes too so hard to compare).
