AMD Casually Announces Machine Learning FSR

Will it run on the CPU? Is that how AMD are getting around the lack of neural processors? Use a much slower general purpose processor.

It explains why a video (OP) about the 9800X3D talks about FSR4.

It makes no sense to put it on the CPU. DP4a just like XeSS is my guess, with a specific hardware acceleration path for RDNA4 and beyond.

It's a major architecture change though. It isn't easy to just drop in ML cores which are integrated into the wider chip. Keep in mind the only reason Intel and Nvidia have it is because they had it from the very first iteration of the architecture.

It kind of depends on when AMD pivoted from, you can just upscale through TAA (hence compatible on all cards) approach.

AMD already has the equivalent to tensor cores in their CDNA GPUs, their UDNA arch which will come after RDNA4 is going to be a big change that will bring the CDNA tech together with RDNA.

But we are talking about RDNA4 here.

I completely get their Ryzen AI chips can already do ML inference and apparently as you've said CDNA.
