Well, with the SSDs in them approaching 3,000MB/sec reads, it's probably faster than RAM from a few generations ago. Can't wait for desktops to fully embrace PCIE SSDs, I'm talking like 6 slots for them + the PCIE lanes required to read them all at full speed. Hopefully Zen will get us closer.

Edit: ooh, and shared HBM2 memory between the CPU and GPU. And make it socketed + upgradable :)
