This is the quote I was refering to:
"Memory bandwidth:
RX480: 256 GB/s
390X: 384 GB/s
ZEC uses a lot of memory operations. Do you still think that RX480 can work as fast as 390X?"
I never said the 480's can do as much as 390's
Please read posts carefully
Yes I know the differences that's why I said that the 480's can do better than what they do right now if tweaked as per their OWN advantages
I also have 390x's and I am really happy with them although they burn much more than the 480's for those of us that do pay for electricity
