AMD release vega and sell the same number of cards as the quarter before, but nvidia sell 4 million more having released nothing new.
That doesnt scream miners snapping up vega.
You can't make that connection from the numbers. Unless your looking at something I am not. These numbers take into account sales to the data centre and in fact any piece of hardware that can run gfx including apu's etc. nv have also done good work and secured wins in the datacenter with the like of Tesla etc which goes some way towards those numbers.
Numbers without context are pretty useess.
