They use a single game. I averaged the games. My results are more accurate than theirs.

I always thought they averaged all titles together.. rolleyes.gif That is a completely useless test then imo. What's the point of only using one damn game.. Furmark too? Wth.. Surely AMD's architecture's would naturally use more power with a synthetic like that? I'll ignore those results from now on.

Ah, I was unaware that 1/16 was a hardware limitation, probably because the GCN whitepaper I've been looking at long predates Fiji.

Thanks for the info.

Rated TDP often doesn't say much, unless it's being used as a throttle point and the apps in question are reaching it.

I have parts of the exact same model that differ significantly in power consumption. This is often the case for certain half-assed non-reference designs that give every GPU the same voltage regardless of leakage.

I didn't read the fine print and made the same assumption at first.

Still, the usefulness of the test would depend on how representative of gaming in general Metro: LL is.

Also don't forget that AMD uses higher default voltages to maximize yields as well to provide a margin incase the consumers PSU is subpar and cant deliver. If you were to look at starting voltage you would fine they are excessive eg. my 390X was set at 1.3V and i could drop it by 0.1V and maintain stock speeds.

They average all the titles for performance and use that in the perf/watt, but they use Metro for the power consumption number rather than measuring it in all titles.

Does HardOCP measure power in every game and average it, or just a single reading? They don't say, they just say they "use real gaming" .

Yeah, i just assumed they averaged all the games because TPU is usually very thorough. I didn't think they would half-ass such an "important" aspect.

It seems that Metro isn't very representative at all, as Mahigan showed by averaging other games together. Not to mention Furmark.. I don't even. doh.gif

I'm aware of the performance averages, i was talking about power consumption.

The performance average is used in perf/watt, but the watt part (and the power consumption chart) is from Metro and not all titles. The HardOCP review doesn't say where they get their power number.

? I know. tongue.gif That was my point, it makes it completely useless. Lets use a performance average across a bunch of titles, including ones like Pcars, and then we'll just use Furmark and metro to test power consumption, throw them together and call it an average. Nvidia wins, case closed. lachen.gif

If you do the math, they used the metro numbers. Just add up all the avg fps for all the games and divide by 22 then take that figure and divide the metro voltage by it.

You'll get their figures. If you compare the GTX 980 and Fury differences, you'll get the same percentages.

Does anyone measure power consumption in all games? You are making the assumption that the HardOCP number is across all games, but they don't say that specifically, just that it is measured in gaming use.
