No, actually, what they are doing has the "disadvantage", that if you
need a GPU upgrade, it means a CPU upgrade, since they are the same.
*but* you are losing the bottlenecks that come from *having* separate
components, which means you don't have to even improve the GPU itself,
to get improved performance. And, yeah, that has some drawbacks as well,
undoubtedly. In any case, you hear people babbling about CUDA all the
time, so I figured, "OK, this sounds like it kind of kills the whole idea."

Right, because having a single homogeneous processor core, where the GPU
is integrated, would *completely* hose the idea of OpenCl, which depends
on, "Being able to handle code execution on *any* machine, without
regard to the platform." Guess what, anything that boosts performance of
the CPU/GPU combination by 80% is going to improve the speed of
*anything* that involves running graphical code, including OpenCl. So,
yeah, its pretty irrelevant to the issue of whether a "graphics
specific" language might get hosed by doing this.
