Shared memory between CPU and GPU isn't exclusive to consoles. All (?) integrated GPUs do it. Mobile devices, PCs, Apple Silicon, it's all the same.
The only big difference is consoles have the CPU using GDDR memory (what dedicated GPUs use) instead of typical DDR. You're not going to need to code anything differently for that but it will have different performance characteristics.
- monsieurbanana 8mo agoI think you very much want to code differently if you were to target gddr instead of ddr. Unless you were only working at a high-level of course, but it would significantly influence eg the rendering engine
- vzaliva 8mo agoIs it something wihch would make PS5 attractive to run local LLM models? I've heard Mac Mini shared CPU/GPU memory makes it popular for that.
- bigyabai 8mo agoNo, unified memory is not a panacea. The PS5 GPU is mostly raster-focused and doesn't have good acceleration options outside Vulkan compute. Your best ~$300-400 option for inference is still the RTX 3060 AFAIK.
- pantalaimon 8mo agoThe Mac studio also comes with up to 512GiB RAM. The PS5 only has 8GiB.
- Rohansi 8mo agoThe PS5 has 16GiB but your point still stands.
