This is a big win for nVidia on the supercomputer side of things. They will soon have to face integrated CPU-GPU solutions from Intel and AMD which greatly simplify the process of building and programming a supercomputer. They've just one-upped them both by creating a similar offering with better performance on the GPU side (where the FLOPS are) and better power efficiency on the CPU side. In the race to the exaflop, nVidia just changed the odds dramatically.
