Phoronix: AMD RDNA4 "GFX12" Support Merged For Mesa's RadeonSI Driver

Following all of the GFX12 code and related IP landing within the AMDGPU Linux kernel driver as well as the LLVM AMDGPU shader compiler back-end and other code in enabling the next-generation of AMD Radeon graphics, the RadeonSI OpenGL driver support for RDNA4 (GFX12) was merged this Sunday into Mesa...

Looks like something will be released soon. While I'm satisfied with what I had got from the RX6600, I got that card at the end of the pandemic crazies, at a price only reasonable, so I will be looking for something at least 50% faster in a similar power draw, since my case (which I had no desire to replace) can only accommodate cards bellow 30cm in length.

From looking at the patch, nothing stands out as having changed in VCN5. It's still decoding JPEG/H.264/H.265/VP9/AV1, and encoding H.264/H.265/AV1, same as VCN4.

They should consider vvc/h266...

That would be the obvious next thing to add. H.266 decode is expected in Intel's Lunar Lake (mobile), which is supposedly a 2024 product, 2025 at the latest. Maybe not Arrow Lake which uses older graphics, but graphics and video should have been disaggregated from each other already starting with the tiled design in Meteor Lake.

Really not much has changed since at least RDNA1. Only AV1, and some resolution increases (and the old MPEG2 being removed). Intel continues to have better media blocks, especially for the iGPUs. Meteor Lake supports AV1 encode. And then there's not having to deal with gimped Mesa either for team blue.

AMD's Phoenix supported AV1 encode several months before Meteor Lake even came out.

Don't forget the Intel GuC Firmware issue still not being totally resolved...

Lol, as the other person pointed out, I guess you really don't have to worry about Mesa being gimped because you don't have any acceleration at all.

True. I wish the desktop Zen 4 SKUs had an iGPU that was based on RDNA3 instead of RDNA2.
