nvidia started with competitive price (unlike in the past) and they increased power consumption of their cards.

increasing power consumption to increases performance is a "cop-out" for performance-efficiency ratio.... if amd is doing 100 fps at 280w and nvidia is doing 120 fps at 320w LOL 

maybe they knew amd has something nice coming out.

amd radeon vii is 100mhs at ethash, big navi should do 150mhs

if this is true big navi having ~50mhs more hash than 3090 is a no brainer for mining, even if some can argue that that is just for ethash, the HBM new gen might pull off a winner here.
