As always, wait year or two so drivers catch up.

A decade or two with Nvidia.

Nvidia has long been ahead of AMD. They seem to be close to parity right now thanks to Valve’s efforts, but that has historically not been the case. AMD was the one that needed a decade to catch up until Valve started helping.

I wonder if the Radeon driver has gotten reliable GPU restart support. The GPU becoming unrecoverable if a shader crashed was long a major issue on Radeon on Linux, and I am not sure if valve fixed it for AMD.

I'm really intrigued to get one, but where is the 32GB version for all the LLM goodness?

It’s a $600 card with 16GB of RAM. That’s a good deal.

The 4060 16GB was only about $440 a couple of months ago.

Is modern Radeon support on Linux still great? I've heard that NV Geforce on Linux was kinda bad since ever, but it has massively improved over the past 3-4 years. Is Radeon still the way to go for Linux? EDIT: My usecase is a Linux gaming PC. I was fortunate enough to score an RX 6800 during the pandemic, but moved from Windows 10 to Linux a month ago. Everything seems solid, but I'm looking to upgrade the whole PC…

I have both a modern Radeon and Nvidia card in my PC.

Radeon overall offers a smoother desktop experience, and works fine with gaming, including proton-enabled games on Steam. OpenCL via rocm works decent, with some occasional crashes, in Darktable. Support for AI-frameworks like jax is however very lacking, and I spent many days struggling to get it to work well, before giving up and buying a nvidia card. geohot's rants on X are indicative of my experience.

The nvidia card works great for AI-acceleration. However, there is micro-stuttering when using the desktop (gnome shell in my case) which I find extremely annoying. It's a long-known issue related to the power manager.

In the end, I use the nvidia card as a dedicated AI-accelerator and the Radeon for everything else. I think this is the optimal setup for Linux today.

So about 20% better value than Nvidia comparing MSRPs. Not terrible but that’s what they offered last generation and got 10% market share as a result. If the market price of Nvidia cards remains 20-50% above MSRP while AMD can hit their prices, then maybe we have a ballgame.

These are gaming cards. If you think AMD is lacking here with just 16GB I can only assume you never bought NVIDIA gaming cards in the last 10 years.

You can buy used nvidia tesla p40 with 24GB from 2016 and unlike AMD, they still have CUDA support. The only thing they are missing is support for the latest data types like fp8.

I don't know if I'm in a parallel Universe or hallucinating, but these are graphics cards, designed and created for people to install in they deskop PCs and run games. Just like they have been doing it for decades now.

What's with the P40, CUDA and fp8? Seriously people, chill. AI has been using graphics cards because that was the best available route at the time, not the other way around.

Otherwise I must question, why don't you talk about DisplayPort2.1, DirectX12, FidelityFX.. and other dozen features graphics related.

> support xwayland acceleration (mostly due to Linux mainline making it harder for them) This is not true. There were many differences with how Nvidia had been doing things in their drivers (partially due to them reusing code on all platforms) and how Mesa/Wayland was already doing things, namely with explicit/implicit sync and GBM/EGL streams, but there was no intention to make things hard for Nvidia. Mesa/Wayland e…

DMA-buf was GPL symbol exported specifically to make things harder for Nvidia. This is well known and is not the first time mainline developers have intentionally sabotaged third party driver developers. Saying otherwise is contrary to reality. Reusing code on all platforms is a reason why the Nvidia driver has long been so good. It deduplicated effort so that they could focus on making the driver better. AMD avoided…

Because any code using it was considered a derivative work and thus should be under GPL too.

That's what happens when you try and shoe horn non-GPL code into the kernel.

That is likely to be AMD’s workstation variant. Here is the workstation variant of the 7900 XTX that had double memory:

There were rumors that a 32GB skew is coming.

And AMD already said there is not a 9070XT 32GB coming. Which I understand as "we're building a 32GB card with this chip, but it's not coming before christmas and will cost you a kidney". I really would like to upgrade from my 2070 Super but I'm not getting a 16GB card now just to buy another one with 32GB later on.

I don’t believe that considering that there was a 48GB 7900 for the workstation market:

The denials are probably more saying that there will be no consumer targeted 32GB version than that there will be no 32GB version at all.

Yes, I agree. It will probably be a 3000$ unit.

It was a maintainer decision. The symbol could easily have been a regular export.
