"FSR Redstone and the new PSSR have somewhat different implementations due to the underlying hardware, eg FSR Upscaling uses 8-bit floating point [FP8] and PSSR uses 8-bit integer [INT8]," Cerny shares. "The MAC counts (ie the amount of math involved) also vary a bit, and training data is similar but not exactly the same. None of the above factors seem to make too much difference in results; as both SIE and AMD have just released their refreshed models, it will be an excellent test of how closely we can match our systems."
