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
In terms of raw computing power, the 390 has 2560 processors, while the 480 only has 2304 cores. The 390 memory is also faster.
