From a brief skim of the whitepaper, it seems like the general idea is something like “GPUs are <big-multiple> faster than CPUs, because GPUs are built ground-up for parallel computation. The bottleneck now is parallel memory access, let’s build a chip from the ground up that is <big-multiple> better at parallel memory access”.

Not an entirely unconvincing idea, in fairness, but what strikes me as odd is that they’re trying to patent and sell the idea, rather than the technology.
