the issue isn't only heat, but also semiconductor degradation.
each transistor has a voltage limit to be wary of, this is known as semiconductor breakdown voltage.
too much voltage can erode or even puncture the semiconductor, destroying the transistor as a result.

I simply want performance. Couldn't care less about power consumption of GPU's. 100W will not be notable on a power bill, and if an R9 390X can be kept cool, so can a Polaris graphics card.
yes, including Tonga and Fiji.
and no, clock speed to voltage ratio is still limited.

Yes, but the 480 is designed to fit a mid range role where people won't be having cases with amazing airflow or the strongest PSUs.

The reason why the 480 has problems is because of its low efficiency. If you have to search around on the internet for mods to increase the power limit past +50% to do any decent overclocking, then something is seriously wrong.

The RX 480 is indeed a awesome piece of hardware.Allready smoking the 1060 with early drivers. Lol my ash off!! biggrin.gif
Say goodbye 1060 DX12!!

Where exactly are you seeing it "smoking" the 1060? Sorry, but the 1060 out performs the 480 in 80% of games. And the AIBs are pretty much the same price. So for DX11 $/perf is actually in Nvidia's favor.

Efficiency. If AMD would wanted to be efficient they would sell 4GB cards only with little lower clock and better chips.... but would they have to delay and more cost? quantity over quality? You choose.

Well RX 480 is not that bad and if you want efficiency just undervolt it and clock it around 1150MHz/4000MHz - you will probably get around 120W.

How interesting that Doom is sitting at the Directx 12 end of the table. This graph needs a chronology.

Well isnt RX 480 faster in wicther 3? and DOOM VULKAN only 14%? Should be Rx 480 faster in ashes DX12? should I go on?

they're about equal in both of those in all reviews I saw (Witcher 3 mostly goes to 1060)

was surprised myself about Ashes
