You forgot to state that we could crossfire these two r9 chips and while its not as efficient as cpu/ gpu. It would be a good opportunity for amd to release a htpc low profile r9 series, msi made an itx one but its still full sized single slot. Theres also a good opportunity to get a tad faster gaming apu to people on budgets, theres a way to do this economically. I just cant think of it right now.
I mean you want a smaller desktop right? I do, i myself hate giant turbo fans of cases. It performance of the r9 on die chip would be slightly less than a full sized gpu but it would rely on system ram instead of built in limited memory modules, yes gddr5 is fast but if you pair 2400 16 gb ram with an r9 apu thats a super small footprint possibility alongside using a watercooler or the shurikin paired with an htpc case, mmmn sexy.
It wont be suicide to their gpu crowd, it will merely make those full sized gpus more attractive cause performance boost.
And to whoever said 220 tdp processor thing, exactly imagine that with an apu, that would be amazing. Already an apu puts out 95/ 100w and its an r7 so if we go to r9 im predicting hypothetically 120w- 180w power consumption on the chip alone.
Also off topic but these cases are cool
