It *would* be nice to know. We'll find out soon enough. I read that Vega frontier is ~ 1080ti, Vega rx56 ~ 60mh, Vega rx64 ~ 80-100mh on ETH.
Haven't seen these numbers authoritatively confirmed anywhere yet. Its unclear how the Vega rx series could be so much faster than frontier.
One rumor from ONE source "gibbo" (sp?) from a UK seller quoting a "AIO employee" who supposedly said there's a big improvement on some unnamed driver version.
I would NOT be shocked to see a substantial improvement from driver optimization, and likely some from mining software optimization, but I want to SEE double before I believe it.
