Giuseppe Nelva of DualShockers.com explains the technical ins and outs of the future-proofing features named by Mark Cerny for the GPU of the PS4 like Ray casting for Audio, World Simulation, Decompression, Physics Simulation and Collision detection.
The RDNA 4 upscaler is the first result of AMD/Sony's Project Amethyst collaboration.
They are basically working together to co-devlop the cnns and strategies for game graphics. So the research benefits borth products and they will share similar capabilities. So its not exactly FS4 that comes to PS5 but rather the models that then used by PSSR. Their long term goal together is to develop hardware that maximizes the execution of ML. This longterm goal will impact things like the PS6 but doesn't sound like it is focused on acceleration graphics only ML. This is big for AMD and will make them more competetive in the AI landscape.
PlayStation lead architect Mark Cerny has offered an explanation on PlayStation's focus on GPU power over CPU upgrades for the PS5 Pro.
Only logical really. Had this argument loads on here. "Why have they not changed the CPU". Well it's costing £700 without doing that. How much did you want it to cost exactly doing both? CPU based games are probably 1/10 to GPU games' 9/10. That's why the money should be in the GPU
He could have made compromises to improve not only the GPU but the CPU as well. The CPU inside the PS5 is equivalent to the Ryzen 7 3700x. If he had approached it with the same logic as a PC gamer/builder, he would have left out the wifi 7 card and used a 1 TB internal storage instead of 2. That would have reduced the total cost of the system enough for him to add a CPU that is equivalent to a Ryzen 5 5600x or better while releasing it at $700.
That would have felt like a true generational leap over the base PS5 without having to rely on PSSR.
There is a reason Digital Foundry asked that question because they too believe the CPU could have been upgraded.
Anybody else get the feeling after that presentation that ps6 might not be backwards compatible and almost certainly not with ps4 games.
I'm not impressed at all with what PS5 PRO brings to the table. It's not worth the price imo.
The Digital Foundry PS5 Pro tech interview with Sony's Mark Cerny and Insomniac's Mike Fitzgerald, discussing PSSR and the PS5 Pro's design and development.
Basically, it allows the GPU to be used for tasks that would normally be handled by the CPU. Whenever the GPU will have unused potential, which is ALWAYS, it will be able to handle computing tasks.
And GPUs are several orders of magnitude more powerful than CPUs, because they are made out of many, many cores that work in parallel.
If you want to see what that means visually, here's a particle system running on the GPU (instead of the CPU particle systems we're currently used to see) : http://www.youtube.com/watc...
In short; PS4 is gonna be an amazing machine
Nice article.
Ps4 has a modest CPU but custom GPU with 64 compute huge increse from 4 compute that the normal pc verion would have.
Xbox has 2 or 4 i dunno.
