With what, a 200W TDP? The APUs already throttle as it is.
Also, 7850 and 7870 are 100 watts and less
No they are not.
HD7870 is 190W, HD7850 is 150W. 270X is 180W, 270 is 150W.
You are wrong.
Reagrdless if you like it or not those are the official TDP numbers.
Power numbers are under gaming load. They may be significantly higher under compute.
Under heavier loads the 7870 is generally around 125-130W. Lower than TDP but significantly higher than any APU to date.

Stick on a quad CPU and you are looking at at least another 60-85W.
My 7870ghz edition was rated at 175w TDP max, and 10w at idle, that was on the box itself.
7870 may have 175W TDP, but that doesn't mean it can't be configured to run on lower TDP. In fact Pitcairn is a a mobile 7970m with 100 W TDP:

The 2 products you compare doesnt run at the same speed. Also one cost significantly more than the other.
If you wish to get the absolute best bins for your APU dream. Then price will follow up.
I would suggest looking at the m295x to get a better idea of what might be possible with a smaller version of that in an APU.
Premium price for premium performance or does that only work for others?
Hynix only sells 1 HBM. Its 1Ghz, 1024bit and 1GB. There is no 512MB HBM or 1.25Ghz.

If only 5-10% of your entire bins that hit those targets....
M295X is a 125W chip (using notebookcheck).
That die is already ~360 mm^2. Add 2 modules, uncore and cache and you are easily over 450 mm^2, HBM or not.
Yep, and compounding that is the fact that that many shaders is simply unfeasible in most notebooks meaning that AMD would have to make at least two dies. (Its unfeasible to deactivate that much to get it in a 35-45W tdp window).
LOL, we are talking about a similar chip with far fewer SPs. Before we were just talking about 7850/7870 taking over 100 watts. Talking about something similar but smaller that would go well in a APU.
Yes and you are picking mobile dgpus which are the best binned of the lot. Unfortunately when you put graphics cores in an APU you don't get to pick and choose the better bins. M295X is a huge chip that consumes 125W and is overheating in the imac (105C).
My point still stands. A 7870 (1280 shaders) is over 200 mm^2 on 28nm. Sticking 2 modules, uncore, cache, and other features such as true audio will easily be another 100+ mm^2. The end result? A taheti sized chip that must be sold for a taheti like price and is too power hungry to fit in mobile.

And? It will be a balanced setup for desktop and with far lower total cost than comparable solutions. I dont think they will do it. But the market is there. Its where the majority of discrete cards are sold meaning there is a need and a willingness to pay for that need.
there is so much wrong with this post I am not going to bother.
Even if the performance can somehow reach 7870 levels in an APU (which I seriously doubt for a long time if ever) I would still prefer a discrete card in a desktop, because you can upgrade it without replacing the cpu as well. With gpus progressing still faster than cpus I would much rather not have them tied together, since a gpu upgrade is much more likely than a cpu.
