Undervolting

We discovered in our first reviews of the Vega architecture that the card responds well to a little undervolting and so, exploring that idea further, we have three sets of results today. Stock and overclocked as you have come to expect, but we're also running a stock card undervolted in the hopes that this will give greater thermal overheads, thus allowing the card to boost higher and bring better performance.

Overclocking

Now we've undervolted it we had to see how fast we could push the card and as you can see it ends up much higher than the default clock speed. Clearly a little time overclocking the RX Vega in the right manner brings much greater rewards than simply pushing everything northwards and hoping for the best.

What an odd GPU. I mean, the design of the NANO Edition is very good, but the BIOS seems a bit odd. Then again, Vega is just an odd architecture so I'm not really sure if PowerColor were just trying to pick the better of two evils. Users can still use Radeon Chill (which is excellent) or MSI Afterburner to hit the numbers they prefer. I wouldn't buy one of these necessarily over a 1070 or 1070Ti for a compact system, but it does seem like a cleverly-designed iteration.Quote

Would be interesting to see how it does under water. ITX cases with small GPUs just makes it 10000x easier to build a loop in. If it's anything like that last nano it's just a few % slower yet at half the power draw.Quote

Power consumption with undervolting (but still no OC) in Tom's testing show it's higher than at least one overclocked 1080Ti.

Even if you knew that or weren't referring to it, I still love saying it. It reminds me not to trust even guys as down to earth as Raja who make bold claims about their gear.Quote

I'm referring to the previous Fiji and fiji nano cards. I want to know if this is the same situation when overclocked. Within few performance difference yet half the power draw when under water(under water that way we don't get thermal throttled)Quote

Just how much juice are they suggesting it uses? My 56 happily runs ~1670MHz at 1.075V which at full chat seems to use about 240W even with +100% power limit enabled. I can get it to run 1630MHz on 1.025V which ought to put it close to 210W. At these speeds, it matches a GTX 1080. Clocked to the limit around 1730MHz at the full 1.2V with +150% power limit, it’s well past 300W. The boost in performance isn’t worth the giant leap in power consumption.Quote
