You cant have 6 I7s on one system. :p but you're kinda right, my RX 480 doesnt beat one core of my 7990 from 2013 lol. (except in stability)
AND efficiency. Don't forget the MUCH lower power usage.
trust me, it's not that much better. I mine with my 7990 undervolted hard, I cant do that for some reason with my 480. it's a lemon.
PS: Obviously I'm talking core per core
