I wonder how complicated it would be to make happen / how likely it is to happen, for the Apple way of sharing memory between CPU and GPU to become a thing on PCs. Could NVIDIA do it unilaterally or would it need to be in partnership with other companies?
Could anyone who understands this hardware better than me chime in on the complexities of bringing unified ram/vram to PC, or reasons it hasn't happened yet?

- kalleboo 3y agoAMD built "Heterogeneous System Architecture" for their APUs to do the same thing, but since their APUs all ended up mostly targeting cheap/low-power/low-profile laptops and business machines, it was never actually utilized (from what I've been able to find, there's no public API to actually use this as designed and you still have to copy things from "system RAM" to "GPU RAM" even though the hardware was designed to support zero-copy, whereas Apple has made it all automatic when you use Metal)
