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

Apple 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.
