It would be cool if Sony went the chiplet route similar to Mi300.
I'd imagine PS5 Slim would consist of one of each.
6nm AID chiplet,
5nm 40CU XCD chiplet,
5nm 8C CCD chiplet.
PS5 Pro would use a bigger AID to include a 2nd 40CU XCD chiplet.
Doing chiplets would be not only be convenient for making a Pro model but also for yields.
Plus for the Pro, the inclusion of a 2nd XCD would allow for these two modes, which maybe good for the PSVR2 as well.
Scalable Link Interface (SLI)
Split-frame rendering (SFR)
This analyzes the rendered image in order to split the workload equally between the two GPUs. To do this, the frame is split horizontally in varying ratios depending on geometry. For example, in a scene where the top half of the frame is mostly empty sky, the dividing line will lower, balancing geometry workload between the two GPUs.
Alternate-frame rendering (AFR)
Each GPU renders entire frames in sequence. For example, in a two-way setup, one GPU renders the odd frames, the other the even frames, one after the other. Finished outputs are sent to the master for display. Ideally, this would result in the rendering time being cut by the number of GPUs available.
Mark Cerny has patents similar to how these two modes work. This is one of them, which would be good if used in the Pro.
System and method for efficient multi-gpu rendering of geometry by subdividing geometry
FIG. 2 is a diagram of a multi-GPU architecture wherein multiple GPUs collaborate to render a single image, in accordance with one embodiment of the present disclosure.
Zen4c has great die space area saving at the same performance which would be great for consoles.
Also, PS5 Zen2 looks like half Zen4c.
Especially the FPU.
