Right? |
I picked the move engines info from GAF. Basically all I could get out of it is that they had to do with assisting data movement between the various components. This is supposedly what will make up the transfer rate differences between the DDR3 ram and the sDRAM. IDK, its really an uknown at this point and could very well be for something completely different. But looking at the diagram VGLeaks supplied, it does make sense.
Nintendo/MS both must of decided that it was more important to save money on the main RAM and supplement its lack of speed with embedded ram. Sony seems to have wanted to fix its developer complications and stick to something that is very similar to PCs, thus it went for the costlier GDDR5. Since it is already a very fast memory, the embedded ram isn't needed.
