Today, the $700 PS5 Pro is already capable of delivering sharper, smoother, and more stable graphics than a regular PS5, especially if you sit close enough to the screen. But starting in 2026, Sony plans to integrate a new AI upscaling technology that will make games even more detailed. It will be based on FSR 4 from AMDwhich is used in the new RX 9070 and RX 9070 XT graphics cards and is already showing competitive results compared to Nvidia DLSS.
«Our goal is to deliver something very similar to the FSR 4 upscaler for PS5 Pro in 2026 as the next evolution of PSSR,» PlayStation Chief Architect Mark Cerny told Digital Foundry.
Many new PS5 Pro games already use the PlayStation Spectral Super Resolution (PSSR) AI upscaler, which is based on AMD technology. It allows you to instantly convert 720p images to 4K, while adding particle effects. This technology looks much better in terms of quality than, for example, FSR 3.
But the cooperation between Sony and AMD was not limited to this. It turns out that the neural network underlying FSR 4 was developed in collaboration with Sony. Now the company plans to integrate some of this technology into PS5 Pro.
In December 2023, Sony and AMD announced the multi-year Project Amethyst project, and now it has become known that FSR 4 is the first result of this collaboration.
«The neural network (and training methodology) used in FSR 4 is the first result of the Project Amethyst collaboration», said Mark Cherney. «It is a more sophisticated approach that may surpass the clarity of PSSR.»
At this time, Sony continues to recommend that developers use PSSR, as the implementation of FSR 4 in PS5 Pro and its games will take time.
Project Amethyst may go beyond consoles. Cerny hinted that the technology could be used on other devices as well:
«To be clear — this technology is not only applicable to PlayStation. It is about supporting machine learning on different devices. The biggest advantage is that developers can easily transfer their code between platforms.»
Digital Foundry has already conducted a detailed analysis of FSR 4 and compared the result with PSSR.
