Sony Brings AI Upscaling to the Standard PS5 With QSSR

Sony is extending AI-powered upscaling beyond the PS5 Pro. The company has announced Quick Spectral Super Resolution, or QSSR, a new technology designed specifically for the standard PlayStation 5.

According to a Sony blog post, QSSR is a "new performance tier of AI upscaling" and comes out of Project Amethyst, the machine learning collaboration between Sony and AMD. It is a sibling to PlayStation Spectral Super Resolution (PSSR), the upscaler that debuted on the PS5 Pro.

Sony is careful not to position the two as equals. It says PSSR "remains the gold standard," and early hands-on testing from Digital Foundry points the same way. QSSR does not match PSSR in speed, largely because the original PS5 lacks the dedicated machine learning hardware found in the Pro. Without that silicon, the base console has to run the upscaling model on its general-purpose GPU resources, which limits how heavy the model can be.

The practical result is a more modest target. Players should expect output closer to an upscaled 1440p image on the standard PS5, rather than the cleaner results the Pro can reach with its own hardware. Even so, an AI-based approach can generally produce sharper and more stable images than the conventional upscaling methods many console games rely on, especially when a game renders internally at a lower resolution to hold its frame rate.

For owners of the roughly four-year-old base console, the appeal is straightforward. A software-side improvement could help newer and more demanding games look better without requiring a hardware upgrade. How much of a difference it makes will depend on how many developers adopt QSSR and how well it is tuned in individual titles.

The move also says something about Sony's strategy. Rather than reserving AI upscaling as a selling point for the Pro, the company is bringing a scaled-down version to its much larger installed base of standard PS5 consoles, while keeping a clear performance gap between the two models.
