Judging by the replies, it seems no one is looking at Apple's "Unified Memory." RAM is on the same silicon with the CPU.

- gpderetta 4y agoApple RAM is not on the same silicon[1] as the CPU, just on the same package. Also it doesn't have significant latency advantages. It has higher throughput, possibly because of a custom controller. The biggest advantage is that the GPU doesn't have to go through the PCI bus to access it. [1] my understanding is that RAM and CPU processes are very different and it is hard to produce a chip with both features while remaining optimal.
