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.

I never compared these 2 GPU's in my posts
But since we are doing this please note that the 2304 cores of 480 are giving out in reality more than 2800
While the 390's in reality give out 2600

If I find the article from experts I will post it in my next post

As for the fact that 480 390 gives so much, I think all the same mistake in the code. I enclose a screenshot of my 480 so, it issues at 190 i6? So take a look at the load on the memory controller !!! He is always loaded with no more than 50%
It turns out there is the load limit that is, if correct the error in the code while working with the controller, and if the load Lift at least 90%, then the rate should be about 360M / h is just slightly less than the 390 - 384M / h but better enegroefektivnosti 480 model 110-150 watts.

That is half of the memory 480 is not used, so the picture is seen in the temperature GPU VRM temperature1 67C, and the second is the same in a simple GPU VRM temperatura2 26C

Most likely a problem in the new processor 480 used, it works with the other memory technology, not as in the previous models. Claymore's application writes on the old technology this reason, even older models such as the 7790 cards and the like get such speeds, as well as 480 in the growth of only 15-20% with each version
