Indeed. Which is why I've been keeping up with AMD's HSA news. Their GPUs that share L2 Cache with the CPU intrigue me. After all, if you're piping data back and forth between the GPU / CPU, all sorts of applications open up.

Unfortunately, there's no real scaling. The APUs are mostly consumer products. The biggest APUs are XBox One and PS4, unavailable to the public.

Still, its nice to see a company tackle the latency issue.
