I doubt thats gonna happen. In my view, the only realisticly hope is a revision of the DIMMs. So we for example gets single serial 256bit DIMMs instead of 64bit. Then a singlechannel DDR4-3200 would yield 100GB/sec.That sounds pretty decent, but isn't the memory bandwidth of a 5870 ~150GB/sec?
Perhaps they can offer two modes until system memory is up to that level, one where you don't install expensive "GPU" memory and another where you can pop in the side memory to have additional memory for the APU other than system.
1-2GB of 150GB/sec memory that granted 5870 speeds on a Trinity+ APU would be fine for me, and likely cheaper than the $250-500 for a high end GPU. This would be an ideal desktop for me.
We are borderlining now to the old days before we got SDRAM, where you had 4 FP/EDO modules to fill up the bandwidth. And we see tripple/quadchannel on LGA1366/LGA2011 already.
The parallel nature of our current DIMMs is also utterly hopeless.
DDR4 would be the perfect time for it. Else we will have to suffer until DDR5 or beyond.
