Let's not judge so fast. AMD has a small advantage with their fabrication process (14nm instead of 16nm) and HBM memory. Both usually rise energy efficiency. The base specs don't look bad. If the supposed 4096 cores are correct at speeds of 1.5GHz, it will be very tight for the GTX1080. But then Vega aims for the Ti model anyway and that's a challenge I'm not sure it will win.
Sure, they claim 12.5 GFLOPS, which is more than 10% higher compared to the NVidia GP102. But these 10% can be easily lost in bad OpenCL software, which is their weakest point.
I guess it will be like Ryzen - nice, reasonably priced, very competitive, maybe even faster than NVidia on some terms. But also with deficits and not at all a no-brainer. NVidia is VERY fast under Hashcat and it needs a lot to get on the same level. Driver, energy consumption, cooling, throttling - lots of things still to mess up with.
Vega is supposed to come end of May and rumours tell the Pascal refresh won't be far away from that date. So it might be an interesting summer. Let's hope they can be competitive and make NVidia slash some prices.
@epixoid: seriously, you have a long discussion with someone who still does Bitmining AND does it on usual PC hardware?!? You must have a big heart
