Now that the PS5 Pro has been revealed, we know a little bit about the hardware that will be powering it. Sony hasn’t come out and revealed exactly what generation of graphics it's going to be using, so for all we know, it’s still using the RDNA 2 architecture found in the original PS5. After all, if it was using a newer architecture, the ‘47% increase’ in compute units would mean an absolutely monumental lift in performance if it was running on the yet-to-be-revealed RDNA 4 architecture that AMD’s next graphics cards will be based on.
Yet, there is bespoke hardware in the PS5 Pro, allowing it to use PSSR (PlayStation Spectral Super Resolution), an AI upscaling engine that sounds an awful lot like Nvidia’s DLSS (Deep Learning Super Sampling). AMD has yet to update FSR (FidelityFX Super Resolution) to use the machine learning hardware built into RDNA 3 graphics cards, but that could very well change when the Radeon RX 8000-series is revealed – whenever that will be. PSSR is Sony and AMD’s solution for AI upscaling for the PS5 Pro – and likely the PS6 if it’s successful.
Beyond the fact that it uses machine learning tech to upscale games better than the traditional checkerboard rendering pioneered by the PS4 Pro , Sony hasn’t revealed much. Luckily, we can speculate based on existing AI upscaling tech, namely DLSS. DLSS, or Deep Learning Super Sampling, is the upscaling tech for Nvidia’s last few generations of GPUs – dating back to the RTX 2080 in 201.
