AVX-512 : not yet ; But has an improved AVX2 "AMD has stated that there is no frequency penalty for AVX2, based on its energy aware frequency platform" https://www.anandtech.com/print/14525/amd-zen-2-microarchite...

thunderbolt: in some motherboard: "The ASRock X570 Creator is focused towards content creators with a range of high-end features including 10 G LAN, support for DDR4-4600, and dual Thunderbolt 3 Type-C ports. " https://www.anandtech.com/show/14461/made-for-creators-asroc...

Oh! Well, motherboards like this one, with TB support, will certainly nudge me towards AMD. Let's see that ThreadRipper then!

Unfortunately there's no news of threadripper for Zen 2 yet. Hopefully we'll hear something about it sometime next year. The assumption is they're using all their initial production capacity for consumer-grade (Ryzen) and server-grade (Epyc) chips first.

A new Threadripper has been confirmed for late 2019.

AVX-512: No, "only" AVX-256. https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#AVX...

Thunderbolt 3: Supposed to be added to the X570 chipset.

Some AMD boards already support TB. Gigabyte for example sells an add-on card for some of their motherboards that adds TB3. https://www.gigabyte.com/mb/thunderbolt3/overview

Isn't Thunderbolt superseded by USB 4 now (or whatever they'll call it)?

USB4 might incorporate some TB3 technology, but that doesn't mean that it will be fully compatible.

People who have already invested in TB3 (e.g. in a LG 5k screen) would certainly be happy to keep it supported.

Good to know, thanks. Luckily I never invested in such devices, since they were always Intel only.

Yes, thunderbolt 3 is open now. There's a few AMD motherboards out there right now that support it but they're not common.

TB is a part of USB 4 spec.
