I thought I read LPDDR4 RAM can run up to 32GBps ... wouldn't that match/exceed the PS3?
Does any mobile chip use eDRAM by the way? Or something similar?

Probably not and maybe they never will. Cache, EDRAM and any kind of embedded memory uses space on your SoC/APU. The more you put, the less space you have to fit the other components of the CPU/GPU. So when you create a chip that's way smaller than a desktop/laptop one and still has to put x264 decoders, radio signal processors and other things, space becomes precious.

I did some research on this the 3DS apparently does have eDRAM ... (30-50GB/sec supposedly) ... the original model had 6MB eDRAM (VRAM) and the New 3DS bumps it even further to 10MB eDRAM, which is the same number as the XBox 360. Not sure if that's conventional eDRAM or not, but it's there apparently.
