Hybrid Memory Cube performance doubles

Gen2 spec doubles the interface rate.

Nvidia stated they would be using the cubes for Maxwell, I assume AMD will do the same - looks like V2 could even make it in time for a Maxwell refresh later in the product life cycle.

Will be interesting to see how much all this additional bandwidth improves performance.

Memory can quite easily be a bottleneck in a GPU, especially in GPGPU applications.

jon has yet to learn the way of the Dremel
I'm quite ignorant of the technology, here ... so forgive if this is a foolish question: can this tech be used to replace L2 or L3 cache on a chip, and if so, wouldn't that give some awesome performance gains for CPU / GPGPU tech? Or is this only relevant to DIMM-type memory?
