AMD Radeon RX 480 Undervolting Performance - Legit Reviews


By lowering the power level down it increases the efficiency of the GPU and for gamers that means you get to hold the boost clock speed longer and get better performance and use less power. Having the ability to turn all the P-State knobs is pretty nice and we are already seeing the new WattMan software paying off. Being able to get a small performance boost while lowering the power consumption and heat levels was pretty nice and it’s something you might want to try out if you happen to have an AMD Radeon RX 480 graphics card. It’s easy to geek out and enjoy seeing performance go up in benchmarks while seeing double digit Wattage drops at the wall!

Radeon RX 480 Reducing Voltage and Increasing Efficiency

Throughout 3DMark Firestrike and Unigine Valley we saw no negative change in performance, if anything they improved in Firestrike. We were able to maintain the 1266mhz boost clock even with it being undervolted slightly and see varying degrees of improvement. Temperature being reduced by 1c may not look impressive, but you see that the fan is now spinning at 44% instead of 50% reducing noise leves. We also see that the GPU power draw is more in line with what we were expecting based on the 110w GPU Core power Draw claim, coming in at 112.5w versus the stocks 124.2w. Lastly we see a drop in maximum voltage delivered to the card, coming in now at .9875v vs the stock 1.0375v, and that’s the magic that made all of this happen.


I suspect this is what the new driver release will d.
