You're giving Intel graphics as a pro for servers using OpenCL? Either way, I don't know about this set-up, but next year a set-up with Cortex A15 and Mali T658 will have shared cache between CPU and GPU, which should be a lot more efficient than anything Intel or even AMD has today regarding GPU compute. From what I understand cache "latency" between CPU and GPU is a pretty big problem in the desktop space, and this ARM concept should make it a lot better.

The "Little CPU" is supposed to be the lower-power Cortex A7. Canonical is very aggressive about supporting ARM chips.

Intel's had cache (last level cache, LLC in the diagram below) since January, 2011:

I'm probably just missing something, but can you explain how the concept is going to fix cache latency CPU <-> GPU?


I'm assuming this:

  Cortex A15 and Mali T658 will have shared cache
  between CPU and GPU
is what you're looking for.


I thought Intel next architecture, Haswell, was going to have the same feature?


No (at least to the same degree), but AMD's next architecture will, and in a much more interesting form.
