The Radeon RX 7900 XT(X) Owners Thread.

Yeah. In pure raster metrics with an undervolt, it gets very close to my RTX 4080.

Where AMD need to make improvements is in RT. At the lower end where heavy RT barely matters as it is too slow (4060 and below), then AMD are much better bang for the buck. At 7900 GRE and above you really need to ignore RT almost entirely to think AMD are a better option overall. When I got my 7900 XT for £650 last July nothing else came close from Nvidia.

I'd personally argue for FSR to better match DLSS than for more improvements in RT.

I don't really care too much about RT at all, I can see that it looks nicer in certain situations but it doesn't ever wow me in the same way that having double the framerate and twice the smoothness does. I totally accept that this is an opinion though and everyone has a different view on it, I play games with a guy who loves just playing at 4k60, everything maxed out with raytracing because all he wants is the best looking game.

I think we've all been saying it for years though, if AMD isn't going to (or can't) offer feature parity with Nvidia (RT, DLSS, Reflex etc.) then the aim should be great raster performance at a better price to performance value than the Nvidia counterpart.
 
Haven't read too much about FSR3.1, will it help make BM: Yukong not look bad on AMD? Only toyed with the benchmark, but can't get over the blurriness of it all. Some of it will be the depth of field (and not being the final game?). Talking about 2560x1440 with FSR 100% scaling.
 
Hi, I just purchased a Hellhound 7900XT, 7800X3D over the weekend, and it is a bit of an upgrade from a 1050Ti :) I noticed some coil Whine, particularly ear wrenching on games that give high FPS, i.e. over 400FPS on Warhammer Space Marine 1 and on intensive games like Witcher 3, GTA V and didn't want to RMA the card straight away as it seems to be a common issue, so looked into all of the information on this over last few days, these are my findings in case it helps anyone else, plus some undervolting success

Coil Whine
I have a Corsair RM850X, with 2 separate PCIE 8 pin adapters going into the 7900XT, initially I used the end of the cable (the daisy chain part) as I thought it didn't matter as each port had a separate cable going in anyway, due to the size of the card it also comes with a bracket to hold the GPU. I switched to the first pins on the cable instead and noticed that the whine was considerably lower testing some games. So I switched back again and the whine was about the same, so my findings on this are that it doesn't matter which part of the PCIE cable connects to the GPU as long as you have a separate cable(I haven't tried daisy chaining one cable so can't comment on that just going by the reviews). So regarding the Whine I think it was caused by either the 7900XT wasn't seated correctly or the cables weren't in securely, as the coil whine has gone now for most of the time and only very low on demanding games/high fps.

Turning on vsync/riva statics max fps, or the Radeon Chill also help reduce it as well. I have a 60hz 4k 27" monitor at the moment so just wanted to know that the coil whine won't be an issue going forwards if I go to a 240hz monitor in the future.
The other way to reduce coil whine was to reduce the core clock to 2000mhz, but takes the performance hit as mentioned in some posts earlier, so think the best bet is a combination of checking GPU power/seating and vsync/capping FPS/power


Undervolting
I managed to get a stable setting (warhammer space marine, warhammer 3, Adrenalin stress test/heaven)
1000v volts
3000mhz core clock
2700 memory clock with fast timing
15% power limit

This actually brings avg fps to 60.9 for 4k ultra in warhammer 3 Mirrors of Madness benchmark from the avg fps 55.4.

I could possible tweak this a bit more, but 980volts 3000mhz core clock or 1000volts with 3050 core clock crashed, so probably close to the limits, I noticed if I enable radeon chill on top of this for games like warhammer space marine it crashed, so perhaps need to test it a bit longer or set up different profiles.

Can you think of anything else I need to try before putting vsync/fps limit on 60hz until I upgrade my monitor in the future?
note, I have DDR6000, CL30 ram and have EXPO enabled, not sure if there are any other tweaks I need

Personally I would just lock it to 57-60FPS, 400fps is just wasted energy and noise. Reducing the core will just cripple games that aren't going to max out the FPS.

Review it all again when you get the new screen :) Will the new screen support AMDs flavour of VRR / variable refresh rate?

Yes it will have freesync but im a bit stuck on what to go for, i dont want to spend the money on a decent 4k monitor as i think a 32” is needed and dont have the room for that on my desk as need to have 2 monitors for work, so perhaps a 27” 1440p 144hz or 240hz monitor in the black friday sales and use my existing 27” 4k monitor for strategy games at 4k 60hz that dont need super high refresh rates

You could always go for super wide and get rid of both monitors 3840x1600 is great for work and not as punishing as 4k.

Blimey that’s a tad cheaper than what I paid when they first came out. Not sure about the cooler but for that price, what the heck.
 
Good evening everyone.
I just got a good deal for the Rx7900xt, but I'm worried, i have a 750w 80+ gold psu, i see some people say it's more than enough and others say it's not.
I hope i get help.
Pc specs, cpu R5 5600x , 16 gb 3200 ram

Yeah, plenty fine, wouldn't worry about it. I use a 750w PSU with my 7900XT & 5800x3D.

Thank you for your reply
I heard there's power spikes or something will it effect or not.
I think my whole system drows about 500/550 max i guess, so i still got at least 150/200watts.
Another thing and I'm sorry for writing a lot , what's the best Undervolt for this card for temps and power draw.
 
Yeah you'll be fine. I have a 850W and I've got plenty of that left. 750W will be totally enough. I would have gone 750W but when I was buying parts the one I was was out so just went for the next one up.

There’s a couple of ways to do it. Test your card first with a variety of games first. Then you can either put a -10 or -15 negative offset or play about with undervolting the actual soc. I’ve not got a 7900xt but I know some of the guys have done tuning and have added there tuning on this thread. The easiest way is to cap the max boost clock. Play about and see how you get on.
