There is no way AMD will use triple or quad memory channel controllers in mainstream APUs. The idea is to keep the design simple, low cost both for the APU and the motherboard and cheap for the consumer, something that Intel Iris Pro is NOT.
They will be able to use Stacked Memory with 22/20nm and beyond.
they could start pushing higher perf apus with higher margins to capture the top end not unlike intel iris pro. Just having the top product, even if it is overpriced can help mindshare. The perfect example is the titan, the fastest card on the block for a while but was the performance worth the premium, didnt matter, cause if you cant get the fastest nvidia card, get the second fastest...here is where marketing takes over, because nvidia had the fastest people associate nvidia with the idea of being faster and subsequently bougt nvidia hardware even is [theoretically] a,d had faster parts than nvidias 2nd best, the knock-on effect.
AMD needs to push graphics beyond what it is worth because that is the only way they can compete. battery life, cpu perf, gpu perf, manu costs, brand equity etc and AMD only has gpu perf advantage but for how long?

Not unlike the iris pro? iris pro performance has zero effect on pricing. It's price that high because, 1. they have to because of the cost of esram and 2. because their monopoly allows them to. AMD have a lot more than GPU advantage going for them. That statement is just nonsense and flat out wrong.
BTW is there a single in depth article on iris pro anywhere on the internet? I mean a thorough one, not unlike the ones reviewers do with other hardware. Examining drivers, bugs, flaws, performance in more than a handful of games etc.?
Slightly off topic here, but Iris Pro is eDRAM, not SRAM.

Different manufacturing process, different equipment requirements, different density. SRAM can be made on traditional logic processes (in fact it's the first thing done, for validation purposes). eDRAM requires special processes that can lay down trench capacitors, which is why eDRAM is almost always a separate die, as is the case for Crystalwell.

It's a small but important distinction if you want to look at the cost for anyone to add eDRAM or SRAM to their products.
This isn't my area of expertise, but I believe they use a multi-pass process. Since eDRAM is composed of logic and capacitors, the build the chip normally to get the logic down, and then finish that off with the tools required to lay down the capacitors. It's actually not any different than how eDRAM is built in the first place, but having the processor logic on the die too would add to the complexity of the process.Out of curiosity, how do IBM do it? I thought that they could now put eDRAM on the same die as their POWER8?
My laptop has a Jaguar, A4 5000, and there's also the A6 5200- as well as some tablets that has the Jaguar APU too (A4 1250, A6 1450, etc). I wouldn't be surprised if AMD puts out an 8 core Jaguar for FM2+.They have released Jaguar in June and still you can't find a single Desktop/Laptop Jaguar product in retail.
Yeah I imagine it does better with a separate discrete GPU, that's actually impressive.
I wonder what AMD has in store for the FM2+ socket, seeing that the XBone and PS4 has an 8 core APU.

Now that you mention it the new Xbox seems to have quad channel DDR3 memory support & that should put the onus back on AMD to deliver something similar for Kaveri in the future ~
Heck, good point. I want to see Soldered in Kaveri boards with GDDR5,
Would make an awesome Steam box
But would there be enough volume to support a new die and mask? The answer is most likely no.

He said soldered in the board, not integrated on the APU die.
It would if AMDs Linux drivers weren't leaving much to be desired.
You assume Kaveri supports GDDR5 in its IMC...
I merely told you what he said because you were talking about new masks and volumes.You dont need new mask and higher volumes if you integrate the ram on the package or in the motherboard.
I've no idea if the Kaveri IMC supports GDDR5.

There was a version of Kaveri with GDDR5 support planned, but that was when "Steamroller 1.0" was still a thing. And since Steamroller 2.0 was a thing ever since c. 2012, GDDR5 seemed to be dropped along with plans for a 3-module version of Kaveri. So the IMC probably no longer supports it.
