AMD RX 480 Review Thread - Page 304

post #3031 of 3674
reference RX480 is also efficient, i think Asus did something to the card itself, bumping the power profile for example.

RX 470 might have better efficiency.

it should be, RX470 will have disabled parts compared to RX480.
at the very least 10% more efficient at the same clock and voltage.

I like that we debate efficiency on an overclocking forum. /s

its now a trend, plus power consumption also affects temperature.
meaning, a card that is more efficient even when overclocked will also be much cooler.

Its very common for AMD GPUs.


But every guy from NVIDIA will probably buy ZOTAC AMP extreme.

To get optimal performance with my card at 1405/2200 (1.2v and .975v respectively) I needed 160%. At 1.25v and 1425 it required 165%.
I'm not sure how safe it is to run these cards at 1.25v.

Efficiency discussions belong on an overclocking forum. When you start off with a card that isn't that efficient to begin with, like the 480, it makes overclocking more difficult.

I'm actually really shocked with how much voltage are running through these cards. My 380x only consumes 1.06V at 1040MHz and its just on 28nm.

As long as temperatures are kept in check I don't think it would harm it short term. I wouldn't suggest 24/7 speeds to utilize that much voltage. I've kept mine at 1380 @ 1.175 for a while now, though.

So can we conclude that if it wasn't for AMD's wish to be power efficient, we could get a heck of a lot more performance out of a Polaris GPU?

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.
