Today, AMD are bringing out the big guns with the formal release of their next generation desktop GPUs with the AMD Radeon RX 6800 and the RX 6800 XT. Announced back in late October, these cards are AMD's first to come with hardware accelerated Ray Tracing support. Although for Linux, we're still waiting on The Khronos Group to formalise the cross-vendor Ray Tracing Vulkan extensions for that.
Here's a reminder of the specifications:
RX 6900 XT | RX 6800 XT | RX 6800 | |
---|---|---|---|
Compute Units | 80 | 72 | 60 |
Process | TSMC 7nm | TSMC 7nm | TSMC 7nm |
Game clock (MHz) | 2,015 | 2,015 | 1,815 |
Boost clock (MHz) | 2,250 | 2,250 | 2,105 |
Infinity Cache (MB) | 128 | 128 | 128 |
Memory | 16GB GDDR6 | 16GB GDDR6 | 16GB GDDR6 |
TDP (Watt) | 300 | 300 | 250 |
Price (USD) | $999 | $649 | $579 |
Available | 08/12/2020 | 18/11/2020 | 18/11/2020 |
For running them on Linux, the driver situation isn't the best. AMD have put out the Radeon Software for Linux version 20.45, which adds support for the Radeon RX 6800 Series but that driver only officially supports Ubuntu 20.04, RHEL/CentOS 7.9 and RHEL/CentOS 8.2. For Mesa drivers, you're going to need Linux Kernel 5.9, Mesa 20.2 (or newer) and also LLVM 11.0 which means most normal distributions will be missing out unless you're prepared to do major manual upgrades. So, unless you really know what you're doing with everything, you will likely want to hold off.
If you do manage to find one because, as expected, most places are sold out and you get everything it needs setup - expect to see some incredible performance. We don't get sent any hardware from AMD, so we're going by what others have been cooking up. It seems Level1Linux on YouTube are very happy with it, and the Phoronix benchmarks show them doing well too. From a price point of view, the performance does seem pretty amazing considering how close it appears to be with the NVIDIA 3080 and if you prefer the open source side of things it doesn't get better than this.
Quoting: ValckQuoting: iskaputtgood availability [...] 500 EurosNot going to happen if the lowest model comes at USD 580.-. Usually that directly translates to €580.-, so I doubt you'll see anything below 600 Euros, and much less five hundred, anytime soon. Add to that the bot resellers, and you're in for a long wait.
You are very likely right, sadly.
Will continue to use my Vega 56 which I bought for 400 and is serving me well. An upgrade would be nice for 4K, but no way in hell am I going to pay 50% more for my next card.
If you want to run Debian, I suggest that you don't run a video card newer than the version of Debian you wish to run. If you stick to that rule, AMD on Debian is pretty easy. You don't really have to do anything except enable non-free repositories and install the linux-firmware package, which you're probably going to have to do in any case. There are ways to run newer cards on Debian, but it is always a hassle to run anything newer than what came with Debian plus whatever happens to be in backports.
Just to be clear, I run Debian in a lot of places, just not on my main desktop to game. I use it on all my servers both at work and at home, and I use it for older or underpowered machines.
Here is an example how you can do it:
#!/bin/bash
base_dir="$HOME/archive/debian"
firmware_dir="linux-firmware"
mkdir -p "$base_dir"
cd "$base_dir"
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git $firmware_dir
cd $firmware_dir
git pull --rebase --prune
sudo cp -v amdgpu/*.bin /usr/lib/firmware/amdgpu/
sudo chown root:root /usr/lib/firmware/amdgpu/*.bin
sudo update-initramfs -u

Quoting: ShmerlUpdating firmware from upstream is not hard. Seriously.
My Debian 9 dinosauric OS is ready
Kernel 5.9.9
Mesa 20.2.2
Firmware added
Bonus: Also have Mesa 20.3 configuration ready, rc2 working fine but I'll wait for the official release.

Yeah, I'm now waiting for Sapphire Pulse RX 6800 XT to come out and actually be in stock. It might take some weeks or even months though.

Quoting: slaapliedjeYou almost need to be running a rolling release like Arch to be able to just pop the card in and have it go.Sounds like a plan to me. Rolling release is where it's at when you're a PC gamer. Or, you can wait, I guess, and watch not only Windows gamers enjoy their AMD cards sooner but also other Linux gamers. You don't have to go hardcore and compile every package like Gentoo or run the Arch installation gauntlet; you can get rolling right away with Manjaro or EndeavorOS boot-able, graphical installers.
My struggle is PS5 versus 6800/XT. My choice right now is the PS5 but, man PC games are crisper and faster than consoles when you don't have to fiddle around with troubleshooting and hope compatibility layers don't break.
Quoting: TobyGornowI would have loved to buy one Rx 6800 xt, money is ready, spammed all day long on my mobile at work, but in my country they were nowhere to be found. Only two resellers managed to put the cards online with no stock to be seen but with a huge premium, even on Amazon the products are a no show.While I wouldn't do what my friend did, he actually bought Intel instead because he didn't want to wait more than two weeks to get his hands on a new AMD CPU last year. Too bad.
So, I'm happy the support is better than usual but what's the damn point if you can't buy the f**king thing... So pissed off right now, they ruined the party for me.
It should be illegal to promote and advertise product that are not fully available. Looking at the Ps 5, Xbox series X, rtx 3xxx and now Rx 6xxx...
Edit : how could I forgot the ryzen 59xx series... MIA too.
Quoting: 14You're saying this like it's somehow a huge struggle, or a show of weakness maybe. :DQuoting: slaapliedjeYou almost need to be running a rolling release like Arch to be able to just pop the card in and have it go.Sounds like a plan to me.

I pretty much never buy hardware before it's been on the market for a few months, or games on day one. For GPUs, good reasons to wait are lower prices, more third party models with perhaps better cooling options, more mature drivers etc. And games, well I'm not really into multiplayer, and it really doesn't matter to me if a single player game is brand new. I guess I'm patient. Not that it matters: A game that's a year old (or ten) is just as good as it was at launch. Or most likely better, with whatever patches, new content etc. that have been released since. And obviously it's cheaper as well.
