AMD FSR 4 upscaling shows much improved image quality, fewer artifacts, but it will be exclusive to newer GPUs (www.techspot.com)

Will this become available in older models like FSR and Framegen or will it be exclusive to RDNA4. It would be a boon to RDNA3 mobile chips if the performance gain is comparable to FSR3.

Don't think it's technically possible, but they haven't elaborated. I'm pretty sure it's new-gen only because of the additional coprocessors and new ray-tracing, but that doesn't mean they won't continue making improvements to previous gen FSR. They'll probably backport some of the general improvements like they did with previous generations.

XESS is hardware agnostic, it's just faster and slightly better with XMX vs DP4A. I'm hoping that will be a similar situation with RDNA4 and earlier. Granted, it's wishful thinking, it would be a shame if that was not the case. There's an entire gen of strix halo APUs with RDNA 3.5 and that would greatly benefit from a better upscaling algo to save battery life/improve performance. Hell, Mendocino, Dragon Range, Rembrandt and Phoenix Point getting RDNA 4 would be absolutely amazing.

  • Yeah. So I guess the next question for me is, does that mean that FSR four is going to be exclusive to,
  • look, I would say it's right now it has to be because of what I just said. It requires a lot of compute to be able to generate the pixels.

Just confirmed that at least on launch it will be RDNA4 exclusive. I just hope it can run on other hardware even if it is a dedicated NPU in mobile chips.

Ye, I'm hoping they will bring it down the line like what happened with FSR2 and Frame Gen.

I thought hardware unboxed asked AMD about this and they said it should be able to run on some higher end older cards, but wont be there at launch.
