on either case, 256bit GDDR5 is too narrow for RX480, they'll either have to fatten it up to 320bit or use GDDR5X.

I will disagree with you. I think that more rops would give RX 480 more performance.

GDDR5 + 256-bit looks to be enough for 1070, how is it not enough for 480 ?

different architecture.

uhhh, no.
rops needs bandwidth to work on their share of resource, they're raster engines that requires enormous bandwidth.
adding more workhorse but not supplying the needed resource would only starve them, meaning each and every rop will be running at less than full capacity.

its like the difference between 2cores at 100% load and 4cores at 50% load.

Different arch. and OC limited at 2250MHz because someone at AMD is a dumbo.

I still disagree with you.
You can compare R9 380X vs R9 280X and you will see that extra bandwidth usually does not help.

to be fair AMD's ROPs are more powerful per unit, this means AMD needs less ROPs to do the same workload as Nvidia's ROPs.

380X is a different architecture than 280X, i don't understand what you're implying?


or perhaps you forgot about this?

Only 1,342 on the core from PC World. It seems like unless you go under water or luck out you aren't going to get more than 1,350 MHz out of the 480. PC world review said to also expect Nitros to hit selves a week from now.

Also remember that it's the 4GB version, which has a much lower memory clock speed than the 8GB version. The 8GB version should perform even better.
