if APUs can do high setting 1080p gaming, amd would make truck loads. this is probably 1 or 2 more generations away. end of 2016 or 2017. that is all amd needs.
High 1080p gaming in 2017 with games from 2014? I could see that. There are several problems with the idea that this will help AMD :
1. AMD has been offering the best IGP performance for over a decade, until the (much more expensive) Intel Iris Pro arrived, and how exactly did it help them "make truckloads"?
2. If possible, AMD needs to find a way to better utilize the GPU power they have to get competitive general compute performance whilst also bringing down their power/heat profile. I keep hearing about HSA, but haven't seen any day-to-day applications that use it...
3. Right now, the cost savings between a high-end AMD APU and a low-end Intel CPU with dGPU still makes the APU a hard sell for desktop gaming.
4. By 2017, 1080p will be the 720p/786p of this era. We'll be arguing about which IGP does better 4K.
The simple truth is that AMD has to be the budget part until it can beat Intel in pure performance (most important) and perf/W (important to enterprise and ecoterrorists). I think AMD's IGP strength is meaningless in the big picture - the only caveat being real-world HSA performance.
I think Carrizo is a good step in the direction AMD needs to go - assuming it is cheap enough to undercut Intel+dGPU or Iris Pro - and assuming AMD's marketing slides aren't complete fluff. Throw in some HBM or another huge cache like Crystalwell and we could see a shift on mobile. Toss Windows 10/DX12 into the mix and then it could go either way. If games/application are eventually able to effectively use HSA across any CPU/GPU on a given system, then what is an advantage for AMD APU would also be an advantage for Intel+dGPU.
