Agreed, that's the most thrilling development to HSA in my eyes. Coherent memory structures (with much of it shared) all the way down truly elevates the GPU to first-class citizenship.

What I don't really see, HSA-wise, is how they plan to cater for the fact that graphics and compute cores favour significantly different types of memory (DDR vs GDDR). From what I understand, one of the major cripplers of on-die graphics so far as been its reliance on the same bog-standard memory interface shared with the CPU. How will this interact with AMD's side-port memory schemes?

  DDR4 will help when it comes to market next year. The speeds start at 2133 MT/s.

  In addition to what other posters have noted... there are rumors that future AMD APUs are going to support both DDR4 and GDDR5 RAM. http://hardware-beta.slashdot.org/story/14/01/20/0159210/amd-considered-gddr5-for-kaveri-might-release-eight-core-variant http://hardware-beta.slashdot.org/story/14/01/20/0159210/amd... AMD has had sub-par (compared to Intel) memory controllers recently. So maybe the improved memory is for naught. Nonetheless, they're working on it...
