PS5 Pro Shouldn’t Be Expected to Deliver Double FPS Over Base Model, Based on Specs Alone; New Upscaling Patent Suggests Evolution of Checkerboard Rendering

wccftech.com:

The PS5 Pro performance shouldn't be expected to be double the framerate in GPU-limited scenarios over the base model based on specs alone, according to a recent analysis.

Speaking in a new video, Digital Foundry's Richard Leadbetter, Alexander Battaglia, and John Linneman commented on the rumored hardware refresh from Sony and the level of performance that should be expected out of it, saying that it is difficult to predict as of now based on the rumored specs alone.

Unlike with the PlayStation 4 Pro, this time around, we are not getting double the number of CUs, so the increased clock speeds may not deliver automatically double the frame rate in GPU-limited scenarios, also considering how the PS5 Pro CPU is going to be a limiting factor, and the VRAM and memory bandwidth staying the same. Any performance improvement over the base model will likely be delivered by the rumored upscaling technology Sony is supposedly developing with AMD. The additional power of the console could also be used to add transformative elements not possible on the base model, such as path tracing.

Speaking about the rumored upscaling tech that Sony and AMD are working on for the PS5 Pro and other hardware, Digital Foundry took a good look at a recently discovered patent, attempting to explain how it works. Though not very clear, the patent seems to point at an evolution of checkerboard rendering which will use an algorithm to determine what part of the image requires upscaling the most.

The PS5 Pro is rumored to launch later this year. We will keep you updated on the console as soon as more come in on it, so stay tuned for all the latest news.
