>I think this hUMA/HSA is a value proposition and not meant for high-end graphics or GPGPU, which can easily stream through GBs of data very quickly (high end cards have > 4 GB on card).
I think the use of it in gaming consoles goes against that a bit. I also don't see why you're combining the architecture with the specific hardware. You're thinking x86 CPU with an embedded-class GPU in it. What happens if they build a high end GPU with a CPU in it? Nothing stops them from putting 4GB of DRAM on the same package as that like they do with GPUs (or did historically with SRAM on Slot-based CPUs). You can certainly imagine a market for both, the later would just be the expensive / high end model of the former.
And if you really, actually need a dedicated GPU for some highly specialized workload, I imagine you'll still be able to buy one. But now you're talking about the market where people currently put four GPUs into one box, which is not exactly mass market.
