The Pro sales page says their RAM is unified, which is more efficient than traditional. Anyone have a concept by how much more efficient unified RAM performs vs RAM?
Their sales copy for reference:
"M-series chips include unified memory, which is more efficient than traditional RAM. This single pool of high-performance memory allows apps to efficiently share data between the CPU, GPU, and Neural Engine.... This means you can do more with unified memory than you could with the same amount of traditional RAM."
- _joel 1y agoIt's unified on the Air too though?
- hasperdi 1y agoyes, all Mx processors have unified ram
- masklinn 1y agoRAM has always been unified on every M series CPU.
- thefz 1y agoIt just means it's shared between GPU and CPU. Has its advantages in specific workloads, but dedicated super fast GPU RAM usually is better. Everything else in this statement in marketing bullshit and Apple trying to look like they invented the wheel and discovered fire.
- tracker1 1y agoThe fact that it's unified just means it's shared between CPU/GPU usage which can be a good thing. A lot of the performance comes from more channels and a more stable distance from the CPU itself... Getting really fast performance from RAM is more difficult with a detachable interface in the middle, and longer traces. Still not the fastest ram, that they use for dedicated GPUs, but faster than most x86 options.
