Sony’s own upscaling tech for the rumored PlayStation 5 Pro – PS5 Pro PSSR (PlayStation Spectral Super Resolution) – is said to offer vastly improved image quality for current PS5 titles.
Over the past few days, we’ve written various articles about the rumored PS5 Pro model after an internal leaked document reportedly revealed additional details and specs of the console. One of the new features that Sony is said to have implemented in its Pro model is PlayStation Spectral Super Resolution (PSSR), which aims to deliver 4K@60 FPS and 8K@30 FPS. In addition to this new upscaling tech, the PS5 Pro is said to offer 45% faster rendering over the current PS5 and vastly improved ray tracing performance.
Although Sony has yet to confirm the existence of the console, various sources have claimed that the leaked specs are the real deal, and InsiderGaming’s Tom Henderson has said that Sony has even launched an internal investigation into the leaked PS5 Pro document. Interestingly enough, Eurogamer’s Digital Foundry has performed a spec analysis of the leaked technical specifications of the PS5 Pro, containing some interesting details about the beefed-up PS5 model.
Aside from talking about the console’s CPU, GPU, and improved ray tracing performance, the article also mentions Sony’s own PSSR upscaling tech. According to the team at Digital Foundry, this technique can be backported to “any” existing PlayStation game, allowing for vastly improved image quality of existing PS5 games. “Sony says that PSSR has a 250MB memory footprint, but interestingly, developer disclosures reveal that the technique can be backported to any existing PlayStation game”, the article reads. “This is at odds with ‘back compat plus’ features bolted on to PS4 games running on PS5, which required games to run on modern development environments (SDKs). This could be of crucial importance in upgrading existing PS5 games that suffer from image quality problems – and we’re seeing a lot of those thanks to low internal resolutions and FSR2 upscaling. The Pro could deliver vastly improved results via its extra GPU power and PSSR upscaling.”
In the article, increased system memory for the PS5 Pro is also being described, saying that the Pro model has 1.2GB more memory available for games (13.7GB compared to 12.5GB in the current PS5 model). “Bearing in mind that the standard PS5 already has enough memory to service a 4K display, you might wonder why this 1.2GB is necessary. Sony cites the use of PSSR with its 250MB footprint as one use-case, while also pointing out that ray tracing features (particularly the BVH structures used to calculate ray bounces) are also memory-intensive. Developers can use the memory as they please, but if they max out the 12.5GB on the standard model without RT features, there’s now memory available to tap into more of the Pro’s capabilities.”

An interesting analysis from the Digital Foundry team, and we can only that Sony will soon officially unveil the PS5 Pro model alongside a launch date and price.
