No doubt some of the increase in hashrate is from the unprecedented success of compromising servers into XMR mining botnets, but come on, average network hashrate just 3 months ago was around 200 MH/s and now it is 1 GH/s. If half of that jump was from Vegas, and each Vega does 2 kH/s, then AMD must have sold
* - oops, I forgot to divide the 800 MH/s by 2...
200,000 isn't all that big of a sales number for what is by CURRENT standards a mid-upper range gaming card - I suspect NVidia has sold a lot more 1080 models than that out of the 15-20 MILLION discrete GPUs they sold in 2017, and AMD sales appear to also have been quite a bit over 10 million - a LOT of that going to ETH miners in 4Q 2017.
It says a lot to me about sudden demand when Newegg went from having a SALE on all Vega models to completely OUT 3 or 4 days later - a month BEFORE Xmas - right in the timeframe that the "big Vega Monero hashrate" guides were getting common.
