The Battle For The World's Most Efficient Graphics Card

I try and beat the most efficient graphics card in the world by poorly tweaking a different graphics card.

It's worth noting that NVIDIA and AMD report power usage differently through software, so it's not really 100% comparable. It's better to have a physical measurement of power draw using something like the NVIDIA PCAT instead.

You should build a "green pc" that is super power efficient. Kinda like the one LTT made a couple years ago

From my experience, using RX 6600 XT and RX 6800. You have to set the minimum frequency to 100mhz lower than max value. The frequency keeps fluctuating if the min is kept at stock value (i think it was 500mhz). Do not worry, on idle, it will not stay at the min frequency, it will downclock to very low value.

You can use the morepowertool to do much more tweaking to the 6600. Lower to power limit to whatever you want, also undervolting the memory.

Cant wait for the next video, where Dawid will compare the most INEFFICIENT GPU's of Nvidia and AMD. Good job man!

[tomvandongen]

Funnily enough they talked about this on DF direct the other week and they concluded that software optimisation is the fly in the ointment with trying to quantify this sort of thing!

[zenith]

Dawid, you have to up the Minimum framerate in AMD Adrenaline to get actual forced OC.

[sammynobrega]

I think you weren't getting any higher clocks when moving the slider because you were hitting power limit, if you moved the power limit slider to the right, it would let the card reach the clocks you want it to, but then again that's against the point of the video because you're increasing wattage for minimal gains probably.

man I miss the 10 series, I remember how damn efficient it was compared to anything that came before or after

[Thomasful]

You can use "more power tool" to reduce the power draw further. You may be able to get down to 50ish watt or something like that.

[zephaniahgreenwell]

You could set a framerate cap. It would reduce the power usage and improve frame times, which looked pretty choppy on the A2000 graph.

[Brando]

Dawid, I just wanted to say you are a great human being and I appreciate your videos.

[joman]

Also with amd's overclocking, your clocks will be limited by the power limit ie( if your clocks are set to 2700mhz, but your hiting a power limit, the clock wont go up until you raise the power limit) as a side note you can use a tool called morepowertool to raise the max and min on the sliders

[CryptoJordanVR]

I remembered this video recently and decided to do my own testing on how to improve GPU efficiency. Only I went about it a completely different way that paid off big time!

I dialed down all the sliders in the Radeon tuning section to their minimum and then at the lowest voltage I decided to slowly increase the frequency back up until I reached as far as I could go while still being stable. Once you reach a certain point you'll have to dial the power limit back up to continue on. Just keep the voltage at minimum!

Using this method on my reference RX 6800, I was able to achieve 85% of the stock frequency! This gave an over 25% improvement to performance per watt in FurMark and as much as 60% in games!

Theoretically speaking, I imagine this margin grows even greater with the more powerful the GPU you use. This is considering how number of GPU cores and the larger the memory bus matters more than raw clock speeds. I'd love to see this tried on a 7900 XTX!

[djsnowpdx]

Did you try limiting the clock speed on the 6600 to -20? In my experience on a 5700XT, that cuts the power draw roughly in half for about 80% performance, no voltage tweaking necessary.

[xXCrazyGamerxX]

Seem to be slightly CPU bound at times with the RX 6600 but still interesting results.

[denverag]

I loved the 5000 series GPUs because you could push a 5700XT to be faster than a 2080 and use 250w. Or you could basically run fanless at 60w on alot of older games

[konga]

One thing I've found with cards that are tricky to effectively limit the power on is that if you limit the frame rate instead, you can get satisfactory power reductions. Limiting the frame rate to the same level as the A2000 may have resulted in a closer match, though it looks like the 6600's advantage in GTA V wouldn't give enough headroom for this to make much of a difference.

1:51 when he said "drop the a2000" my brain went "DADDY LINUS???"

[Matt-oqjq]

i have a sapphire rx6600, and it's night and day compared to my 3050. with the undervolt i've put on it, it never throttles inside of a deskmeet b660, and i have to run benchmarks to even get it above 78C. it's a great card, the only thing i miss from NVIDIA is stability and custom resolutions - the 6600 has a tendency to crash when upscaling and alt-tabbing.
