- AMD accidentally disclosed the FSR 4 source code
- Clues in this code suggest that it could work to bring FSR 4 to the older GPUs
- It may be that it could happen, and it seems that AMD certainly tries to make it work
It seems that AMD has accidentally published the full source code of FSR 4, and the indices of this code represent an exciting index that the new technology of strengthening the frequency of images could come to the older GPUs Radeon.
Tom’s material reports that Team Red’s wrongdoing was part of the release of a new version of his Fidelithysdk, and he was initially taken up by Videocardz and a few lively eyes on X. We know that it was a mistake because AMD quickly retracted the equipment (not before he was strongly sparkling, although downloaded by a little people).
As you may know, the FSR 4 is currently intended for GPU RX 9000 only – it helps the latest graphics cards for AMD Run games, but in the source code which has been briefly exposed, there is an important index that the RED team could consider bringing technology to RX 7000 models.
This suggestion consists of the source code FSR 4 seeming to have an int8 support, or at least working on this, in parallel with the existing FP8 support. We do not need to enter the weeds with what these terms mean, because it becomes very technical and involved.
All you really need to know is that FP8 workloads can be cut much more quickly with current generation cards thanks to their reinforced AI accelerators that are designed for these tasks – and in theory, the presence of int8 would be to facilitate work with RX 7000 graphics cards (it would not be relevant to RX 9000 GPUS).
As the uzzi38 fled on
Analysis: a wider deployment of FSR 4 has a meaning
So what does all this mean? Well, as Uzzi38 notes, it seems to confirm that AMD has at least experienced obtaining FSR 4 on graphics cards from past generation (which would surely be RX 7000 models).
Although FSR 4 remains exclusive to DNA 4 graphics cards – and it was the first taking of the AMD image frequency strengthening technology to take this path, providing AI (automatic learning) for refinements – there is no reason why this cannot be technically executed on older GPUs. The problem is whether it can be executed GOOD (or at least decently), And at what performance levels could play on an RX 7000 card.
Thus, AMD apparently gave a whirlwind, or may currently be implementing it (or trying, anyway). I believe that this is likely to be in preparation, since the experiences in Linux suggest that FSR 4 could well work on the GPU RX 7000, and it is also logical that the red team wants to bring this technology to wear more widely in time. When AMD has more recent advances for current generation GPUs ready to leave – FSR Redstone is on the horizon for later this year – the idea may be to defrost FSR 4 to the next level of Radeon graphics cards.
As for the way it could get rid of, the key is obviously if AMD can ensure that FSR 4 is sufficiently efficient on these latest generation GPUs – or if it does not have to be too watered down in terms of image quality that result.
Even if there is something of a performance, players can take the compromise to improve the quality and details of the image – as well as ghosts and reduced pulls, and other artefacts – that FSR 4 provides its predecessor FSR 3.
In short, it could be very important for PC players with RX 7000 graphics cards – or it could be a burger nothing. I am inclined to the old being the most likely result here, but I obviously take this with the stacked seasoning.
