Radeon ROCm 5.4.1 Released
With ROCm 5.4.1 being released just two days after the Radeon RX 7900 XT and RX 7900 XTX went on sale, you are probably wondering about the RDNA3 support with this new version... Sadly, it's not entirely clear but is on my TODO list to test in the coming days as time allows and other RX 7900 XT/XTX tests wrap up.
But as covered today, at least the HIP component is working and allowing the likes of Blender 3.4 to work on these new Radeon RX 7900 series as well as the OpenCL driver. But as for how well other ROCm components like MIOpen are working with RDNA3 GPUs has yet to be confirmed by AMD.
There have been multiple tickets this week inquiring about the RDNA3 support, but as of writing AMD engineers haven't commented.
As for the ROCm 5.4.1 release today, the "what's new" section of the ROCm 5.4.1 release notes simply mention one new HIP API addition: hipLaunchHostFunc. That new API function is just for swapping the stream capture mode of a thread. There aren't any other listed changes as part of the ROCm 5.4.1 point release.
So at least for now there isn't official ROCm support for the Radeon RX 7900 series, but then again, AMD doesn't advertise the consumer cards with ROCm support... The GPU support in the documentation lists only the Radeon Instinct MI50 / MI60 / MI100 / MI200, Radeon VII, Radeon Pro VII, Radeon Pro W6800, and Radeon Pro V620 cards as being supported by ROCm. Much slimmer selection than NVIDIA's widespread range of CUDA support across their consumer and professional products.
Here's to hoping that ROCm on the Radeon RX 7900 series will be in good shape in full soon and not having to wait for any Radeon Pro hardware based on RDNA3. But at least we know already HIP seems to be in good shape with the Blender 3.4 support in order, OpenCL is working, and I'll be working to evaluate other ROCm components in the coming days to see how it goes with the Radeon RX 7900 series.
The ROCm sources for those interested can be found via GitHub.
