the Sapphire Nitro versions are 1750 on the 4 GB and 2000 on the 8 GB regardless of RX 470 or 480 would that make the 4GB 480 a better option that the 8 GB 470 considering the 2-nd is priced higher
What would the difference in performance be given same Core clocks and stock ram clocks
I was planning to wait for the MSI 480 8GB that has 6+2 VRM so they can have lower temps and have a quiet and more durable overall card but if it comes at 330eu it will be quite pointless to not get a 4 GB RX 470 Nitro for 230 eu instead.
The price / performance difference is huge
6+2 is overkill. On the reference cooler (terrible reference cooler from RX 480) the RX 470 I am using sees maybe 95c VRM temps when I have the fan speed set to be near silent (stock), this is with a 4+1 VRM. VRM temps with a mild OC (1300/1.120v) are under 90c once the fan settles into a steady state under load.
Even with 1.2v/1400 I don't see anything on the board go over ~95c, even the GPU temps are under 75c with the fan ramped up enough.
6+2 or more VRM's are a gimmick with this chip. 4+1 is good enough for anything you would ever get to under water. 6+2 would only benefit with LN2 maybe.
As for RX 470 VS RX 480 at same clocks, under 10%. RX 470 has the same number of ROPs, a few less TMUs, and a few less shaders. Since the design is primarily ROP bound, actual performance difference in games is 0%(ROP bound games)-12%(shader/TMU bound games). In the current games landscape it ends up around 6%, so you are better off spending 10%-20% less for the RX 470 if you can find one (especially with 1750/7000 memory). 8gb vram is mostly worthless at this performance level unless you crossfire.Edited by KarathKasun - 8/18/16 at 7:47pm
