AMD Radeon RX 7900 XTX & RX 7900 XT Arrive For Linux Testing

"you'll need to wait until next week when the actual review embargo expires."

He couldn't publish any more today, even if he wanted to. Manufacturers are strict about when reviews are allowed to get published, and violating that rule could result in getting cut off from future review samples.

If possible, please include fp64 and rocALUTION benchmarks in your tests.

Do the released GPUs really have all that printing on the IO shield? Not that it really matters when installed (I don't stare at the back of my PC), but it does look rather unflattering in the photo.

I'm sure I'll be getting a 7900XT or XTX, I'm just not sure which one yet. AMD reference, or third-party? I'll have to wait to find out...

I wish AMD could/would implement HDMI 2.1 in Linux. Seems Intel might be doing it.

Crap, that's why my new 4K monitor won't accept input over 120Hz over HDMI 2.1 despite both the card and monitor having it?

Edit: buy 4K 32 inch monitors people, they will make you never want to read on a 1080p monitor ever again. I actually bought a second one right after because my eyes cry when I'm trying to read the old one. May just be Linux going crazy with scaling or something though.

Text is so crisp and clear, reading code went from "is my eyesight getting that worse" to "wow this is so easy to read". Videos are still mostly in 1080p and for 95% of games, you won't see a difference without a top end card, but for programming & reading the web, my god, go once, never return.

Best example is this: I switched a video to 4K once and found the image "better" but nothing to write home about. 2 minutes in, I switch back to 1080p, and everything looked blurry and terrible to my eyes. Didn't take 2 minutes to get used to it and I can never go back.

Ideally, 4k 120hz with vrr and HDR (once supported in Linux)

You're using an LG OLED tv with HDMI?

Yes have been for over a year. Not HDR though.

[pete910]

I could be wrong, but both your TV and the 6800 XT have HDMI 2.1 ports.

They are which is why the "HDMI 2.1 support" was always odd to me as it works for me bar HDR

Guess it's for High Hz 4k due to bandwidth.

May I ask what HDMI 2.1 is actually needed for ?
Have a lg oled running fine at 4k/120 with my current 6800xt on the oss driver

HDMI 2.0 for 4k can only output 120Hz signal with 4:2:0 subsampling according to this table https://en.wikipedia.org/wiki/HDMI#R...standard_video
So with 2.1 you might actually get a better quality.

I'm using RX 580 (HDMI 2.0, DP 1.4) with 4k@144Hz (HDMI 2.1) monitor but max refresh rate I can achieve is 120Hz only too. I'll probably upgrade to some mid range RX 7000 next year and with that 144Hz should be possible I guess.

Are graphics card manufacturers ever going to have 4+ of the same plug type... They should make older ports a potential addition to at least 4 of the same of whatever the current thing is

Honestly, the RT (not RTX, please stop kissing nvgreedias ass) obsessions is beyond stupid.

But I know why you want it, to look for a poor justification to give Ngreedia money for a 4090, because we know very well that AMD is still not going head on after the gimmick called RT.

RT will stop being a gimmick when it runs at 4K@120 FPS on a US$ GPU with a power consumption of 200W tops.

I, too, thought that RTRT in videogames is mostly a gimmick, until I played Control & the fully path-traced version of [vk]Quake 1 on my RTX 3060 Ti (via WINE-Staging), which has a TDP of 200 Watts:

And here's the video by Digital Foundry which shows off how transformative RTRT really can be for these old-school classics:

So it's down to bandwith then, makes sense.

Not that a 580 or a 6800xt can do more than 4k120 often
