Checking in with a report on my 7900 XTX. I decided to go the other direction with the undervolt this time and see how low I could push the card. The following settings get me stock performance at 30W less power:

Very happy with this card and I am so thankful I managed to get it far before the current shenanigans with the GPU market.

(For the first time ever, my dyed-in-the-wool Nvidia user boss was considering a 7900 XTX too! The disastrous 5000 series has pushed him towards being unfaithful!

Sorry if it's been asked, but what software is this? Looks like a Linux GPU tool that I didn't know existed?

This is LACT: https://github.com/ilya-zlobintsev/LACT

Pretty much the de-facto standard tool for undervolting all major GPUs now, it's very good.

New RX 9070 XT is such a piece of shit that i'm starting to think about buying used RX 7900 XTX
So my question is about undervolting is it possible to undervolt RX 7900 XTX from 360w to about ~310w without any performance loss or it depends more on silicon lottery ?
I had a bad experience with RX 7900 XT Pulse (absolute turd when it comes to undervolting) but good experience with RX 7800 XT Pure (@230watts about 1% faster than stock)

In my opinion UV is very important not only for power consumption but also for silent operation, lower temps and longer fan lifespan.

My Pulse 7900XTX is absolutely shit at undervolting, -25mV and it starts getting unstable. YMMV, there's people with agressive and successful UV'ing.

Sounds very similar to my old RX 7900 XT Pulse.

Any other brands ? ASRock, PowerColor, Asus, Gigabyte, XFX etc ? Maybe nitro works better.....

The Nitro+ range from Sapphire are their "top" of the line with all the "good" components but at the end of the day YMMV as no two cards are the same
As for powercolor I'd be looking at either the red devil or hell hound as the only difference between the two is the size of the cooler their reaper just seems to be a nothing special close to stock gpu as you'll get from them

Nitro+ 7900XTX here.
I’ve set the GPU from 1150mV to 1070mV and it pretty much holds to all games. Less demanding games can run even with 1050mV.
To run any 7900XTX at 310W without any performance loss is highly unlikely I think.
Nitro+ can go up to ~467W which is totally unnecessary. I’ve settled for 380W as this is an amount of heat that the 3+ slot cooler can handle easily keeping GPU below 75C, and VRam below 80C at 23C room. I may have to reduce power close to 350-360W at summer without A/C on.

Nitro+ fans are very good. They max out at 3200rpm and up to 2000-2100 they are very low noise, to me at least.

So I made an enquiry to PowerColor yesterday about the Red Devil 7900 XTX and unfortunately it seems it's been discontinued

I've also replied and asked if the Hellhound is still being made, just waiting for their response. I'd like some form of PowerColor 7900 XTX to recommend to people!

EDIT: Wow, PowerColor clearly have real humans manning their support line! This arrived about a minute after my reply!

(For context: PCCG is a large supplier of parts in Australia).

7900XTX and 15months of usage.
Win10 home for the first month and later converted to Win11 home.
Card idled at around 22~28W with no mouse movement. Video playing was at 45-48W.
Opening HWiNFO sensors window full screen, it was instantly at 48W.

3 days ago I build new AM5 system (from AM4) with fresh Win11 home. The card now idles at 11-13W with occasional drop to 6-7W and keeps that with HWiNFO sensors window full screen. Video playing <40W sometimes < 30W.
