FSR4 working on RDNA2/3 (unofficially)

This works like XeSS, it can provide better image quality than Xess even. It even works on nvidia GPUs, should work on XSX but won't work on PS5 because RDNA1 lol.

Interesting concept, you still get better performance with it vs. native.

XeSS is still not open source (Intel promised to eventually make it open source)... if it was I bet we would have already seen it on Series X or S (would probably be a godsent on Series S)
 
Given the source apparently leaked it would be possible to port it. The 50TOPs NPUs in 7840U should already be enough (compute wise) to run this. Caveat being the crippling slow memory on the handhelds - but still.

That said - this leaked version still has ways to go quality wise - I tested it a bit today and while it performs better than FSR3 in some scenarios (and even DLSS) it also completely breaks in others. It's with good reasons it hasn't been released in this state.



see above☝️
Strix Point Ryzen AI series APUs have 50 TOPS XDNA2 NPU. Total system: up to 80 TOPS from Ryzen AI 9 HX 370.

7840U is Phoenix Point, featuring a 10 TOPS XDNA NPU. Total system: up to 32 TOPS.

8840U is Hawk Point with 16 TOPS XDNA NPU. Total system: up to 38 TOPS.

Total system TOPS can be higher when the TDP limit is higher.
 
There's a part of me that feels like wccftech are making up sony reaching out to them. It just feels very unsony like, unless it's someone like digital foundry who cerny seems to have a fondness for.
They are not making it up IMO, given the technical difference in the way in which an RDNA4 gpus accelerate FSR4 with latency hiding and how the Pro will need to modify the algorithm to work with minimal latency (less than 2ms) accelerated across the 14MBs of CU register memory the Pro has - similar to the way PSSR currently works -but instead generating FSR4 tensors and applying FSR4's inferencing on the tensors rather than PSSR's.

2020 GPUs get FSR4 support before PS5 Pro...

This frame rate is not bad for an RX7700XT (70TOPS/INT8).
I think FSR4 (INT8 version) is quite practical with RDNA3.
I hope PSSR2(FSR4) games for PS5 Pro (300TOPS/INT8) will be released sooner than expected.
 
If the hit on performance is that small, why not just released it straight from the start on RDNA3 and even 2. Just like Nvidia did with the transformer model.

Possibly because in current state - this version is not what I'd call 'ready to release'.

Extra R&D is needed for the FSR4 INT8 version since it's different from the FSR4 FP8 version. Running FSR4 FP8 on RDNA 3's FP16 wasn't optimal when compared to the native INT8 version.

Remember, AMD recently released Radeon RX 7700 16 GB VRAM edition. https://videocardz.com/newz/amd-launches-radeon-rx-7700-with-2560-cores-and-16gb-memory

The Radeon RX 7700 16 GB VRAM edition's price is lower than RX 9060 XT 16 GB VRAM.

Many of AMD's newer chip designs (e.g. Granite Ridge, Turin, Strix Point, Strix Halo, Kraken Point, NAVI 48, NAVI 44) are on a 4 nm process node with certain production capacity. Radeon RX 7700 16 GB VRAM edition uses the older 5 and 6 nm process nodes.

They will probably get it around the same time, when INT8 model will be decided to be working and ready to release.

Because standard FSR4 require things (FP8) that RDNA3 doesn't not support. And leaked beta version is a fork in progress to make it work on older cards.
Like DLSS3 was 4000 exclusive and DLSS 3.5 supports older cards - it takes time to backport and adjust some things.
 
Just wanna say. FSR 4 is great. I've been so impressed with mine in my front room console replacement pc. Super surprised how well it holds up Vs DLSS. Keep working AMD.

Not the technical details. I meant Sony reaching out to them. Wccftech tech isn't the type of outlet Sony usually reaches out to.

AMD and… Sony/Cerny ;). Come on, you have done so many little steps forward… one more :D!

Honestly its great, just gotta keep pushing. im playing Space Marine 2 at the minute with a couple of mates. Im maxed out settings, everything cranked. 4k FSR4 no frame gen and getting 90 - 110 FPS on my 65 OLED. I have a 4090 upstairs and the experience is more or less identical with VRR.

I suspect the credibility of wccftech is too high - and would get cited by others like DF- so Sony would have got in touch just to make sure the disinformation that might disappoint confused Pro consumers didn't gain traction.
