I'm afraid I lost the source, but this morning I was reading about some fairly in-depth Xcode benchmarks, the dev was saying that there was almost no hit in performance when it hit swap, and speculated that Apple might be getting ready to move past the concept of RAM altogether in a few years. Sounds a little bonkers to me, but the bus to the SSD is no joke
- mikechen233 6y agoNext gen consoles and Nvidia rtx io is kind of doing that with graphics textures. Textures are memory mapped but stored in nvme storage. When GPU reads a texture, it first looks in the ram, if not found in the ram, the controller talks to nvme controllers to load from storage. If you think about it, gen4 pce nvme can reach 5GB/s doing 16k ramdom reads. The bandwidth is getting close to ddr2/3 territory. And new storage tech like 3dxpoint will have ram like access latency to improve small io perf. You will always still need ram, but you can be more efficient at how to use the ram.
