I think this is probably one of the best review I ever saw from Xbit lbas in recent years. Great job Ilya Gavrichenkov!
But I wanna add some points:
1. The "locomotive of evolution" for a truly APU is Sony. Date back in 2000 with the Emotional Engine CPU in PS2, the VPU0 inside is actually an special "DSP" tailor made for executing SIMD.
2. The same concept was further extended by IBM, Toshiba and Sony. The Cell BE used in PS3 as well as IBM Blade Servers has 8 seperated "shader cores" (They called them SPE) for SIMD execution. In PS3, the Physics, sound and video processing is all handled by these SPEs.
3. In PS3's story, we can see back in 2006 when the machine was launched, nearly no application can deliver the promised performance. After 5 yrs today, we can see the actual benifit for the concept. Similar concept is also employed in certain ARM processors in recent years already.
The hybird programming require a completely different programming concept from traditional one. For example, In Cell BE and PS3, we leart that we have to make use the general purpose processor to pump up with SPE with work load data. Lucky, after a few years of development, there is a number of programmers, especially from the embedded and console region, started to familiar with hybird achitecture programming. I think currently it's a good time frame for AMD to push the hybrid processor idea. However she still may need a couple of years for the PC software developers to catch up in order to deliver the full potential of the concept.
