Because of the low memory bus width on the RX 480, memory clock rate is the bottleneck. For mining, it appears overclocking memory and probably downclocking core clock will see hashrate increases. It looks like for Ethash mining, 8GB cards will be king.
There's also word about a 9GHz memory overclock "limit," although don't know much yet.

do'h! ok I have 4x 480 4GB coming so lets hope I can rinse them for their value...plus got them at £175 so maybe will be ok....once I have some benches on Friday evening I can compare to the 8GB version you are all getting
@boysie there's very low availability to 4GB cards at the moment. It sounds the existing batch of 4GB cards are using larger/faster chips because of RAM shortages, so they should overclock the same as an 8GB model. This probably won't be true of later batches, and maybe not all cards in the first batches.
If there are 4GB cards available right now near you, I'd buy them all. 0 available in Canada right now from what I've managed to find.
mid-end of July, together with aftermarket rx 480 You have to understand that both rx 480 and rx 470 have mini ITX PCB which makes it logical for other companies not to use the cheap shit plastic blower but put a nice heatsink+fan and offer it in the same format as Nano and that's what I'm waiting for.

After all... some 380X can hit ~24mh @ 1625mhz memory, and the RX480 should be outperforming it based on specs, but thus far is not....

So I would assume the 4GB may underperform out of the box, but can be clocked to perform just the same as the 8GB model.
Does anyone agree? Or am I missing something?
