that bus still has to keep 8 x86 cores fed on top of that. It is a definitive improvement over the current APUs which are BW starved under DDR3,
i wouldn't be so sure about this
ddr is optimised for random access, gddr for high throughput
gddr for a cpu is probably as bad a choice as ddr for a gpu

The main differences between GDDR and DDR are regarding voltages and burts capabilities, but for the most part they end up implementing the same memory technology.
And yes, GDDR5 is somewhat faster than DDR3. I, however, would not refer to a 50% improvement as "many many many times over," perhaps "half a time over"... ;-)
The point here is that although the DDR5 may finally help the GPU in the APU get the data at the rates it needs, that bus still has to keep 8 x86 cores fed on top of that. It is a definitive improvement over the current APUs which are BW starved under DDR3, but it is not going to offer superior performance to off the shelf PCs.
