Sony’s PS5 Pro To Use A Different Upscaling Technology Called PSSR
More leaks emerge from the wild for Sony’s upcoming console: it is widely understood that the Japanese company will be releasing the PS5 Pro later this year, with significantly upgraded hardware and more performance to enable higher resolutions or refresh rates. On the subject of resolution, Moore’s Law is Dead has published an excerpt of an internal document describing a new upscaling technology.
The document in question is called “Trinity Technical Overview” (Trinity being the codename for the upcoming PS5 console) – in which it describes PSSR, or PlayStation Spectral Super Resolution, “a machine learning-enhanced version of Temporal Anti Aliasing Upscale (TAAU)”. Given that PS5 Pro is expected to be powered by AMD’s RDNA3-based custom GPU, it’s not out of the possibility that this is what AMD CTO Mark Papermaster has hinted in a previous interview.
In the screenshot, key features have been highlighted – including support for upscaling up to 8K resolution at a later date. The current implementation is expected to upscale 1080p to 4K, and according to the document, it takes 2ms for each frame to complete the upscaling process, which will be further reduced via future optimizations. More importantly, this solution will not require per-game training, which saves time for developers and helps with adoption.
A second image published by the leaker has shown examples of PSSR in action, compared to TAAU and AMD’s own FSR2 implementation. One can see the lines of the robot backpack are much more pronounced on the PSSR, especially on the robot’s mouth, which became blurry on both TAAU and FSR2.
In any case, one can expect a significant performance uplift when PS5 Pro is likely to be announced later this year, given its nearly doubled amounts of GPU cores (60 CUs vs 36 CUs), and a much faster custom Zen2 8-core processor with 25% higher clock speeds.

Pokdepinion: The results look quite promising. If machine learning is involved, then I guess it’s going to be equal against DLSS then?
