[OC3D] RX480 power bottleneck? - Page 5

Wait for the 470... my 480 massive undervolt and underclock are indicative of P10 and P11 true efficiency numbers. The problem is they overvolted the life out of the 480 and my 480 undervolted to 1.025V (-125mV) at stock clocks has an ~120W total board draw. That's taking both GPU-Z and my Kill-a-Watt meter into account.

Have not seen a crossfire yet. Maybe because cat 15.3.2:doh: will OC both cards and Crimson 16 whatever will not ? I can OC both of my 285/380 (on water) cards with 15.3 but none of the crimsons (16.x.x) will not do that. Crimson will only OC the card in slot 0. doh.gif

The card delivers 390 performance for less power than a 380X and you do not think they made progress?

I think people compare it to the GTX 1080, since they are both made on a new, smaller node.

1070 is a better example because both use G5.

They made progression for sure.
But they are sitting on nvidia's previous gen performance per watt stage from the 28nm.

True performance / watt isn't a big deal anyway, but power issues of the card, especially with AMD going to lock it up even more to protect motherboards, isn't going to be very nice, and most likely it is going to reduce performance even more.

It was a few days ago until the PCIE problem and that took over as the arguments against the 480.

The PCIE problem has been debunked on Reddit already. Why are people still rambling on and on?

AMD themselves have acknowledged that the problem exists and they are working on it
