A 6570 (close as I can find to a Trinity GPU) has about 60w TDP, meaning that Trinity would also have a 40w envelope for the CPU half, assuming we base it on the 5800k. The 5700 model manages to pack it into a (much) smaller envelope. Granted, IMC is shared, RAM doesn't count in that TDP, and so on, so that allows for slight cutting back.
... Assuming Steamroller has a similar TDP to Trinity, it is actually possible that they could pack a 7790 and 2 modules into one die, and have it fit in the 125w segment. Holy crap.
On the other hand, the 7750 has a TDP of 55w. Much more reasonable to expect.
I'm not sure they'll do it though. It would be nothing short of awesome, but still, I'll set my sights on the much more reasonable to expect 7750-level performance. I doubt they want to go above 100w TDP anyway.
See above for estimations, but don't take it as law. We have almost no way of knowing how the TDP is spread.
They're doing 28nm for kaveri. What does that point to? And also power consumption has gone down on Richland. So yes, we'll expect like 30W CPU TDP while the GPU can eat all they want but i have a sneaky suspicion the APU team is waiting on the GPU process to stabilize and churn out an even lower TDP than aimed target. After all, Kaveri is for increased IPC and even more increased IPS (on top of increased IPC) and lowered power consumption at the same time

And also unlike on Intel you don't need to shell out $300 for a decent IGP.

Read above. It's possible.

Because the clock generator for the main bus also serves as a clock generator for the VGA signal in most boards, meaning that an overclock of said bus throws the VGA off timing. Ergo, most boards disable FSB overclocking if you get video signal from the VGA. A bit weird if you ask me.
If it has 12 GCN compute units that should mean we'll be able to get 768 CUs on Kaveri... Which sits right between the HD7770 (640) and the HD7790 (896). It should be able to Crossfire with HD7790, if those specs are right.

Just like what i said when i saw the future in 2004 ... I had a feeling AMD would launch a platform that combined the CPU+GPU on one die and being able to use both for computing and called it "Fusion" Damn, was i right! Nobody believed me ... I had even foreseen 28nm as the dominating process for AMD in 2013 for both CPUs+GPUs ... But i never foreseen something called "bulldozer" and "being crappy as hell"
Me & my crazy ideas in my younger actually foreseen the future ...

Yes. If one can nearly max out any game (not C3 of course. Forget about that one, higher end GPUs have trouble as well.) in 1080p with a 7850 i don't see why a supposedly "7790" will not do it and have more room to spare

How true is that? Look at 2133 benchmarks and you will know it.

However, after the bulldozer disappointment I take AMD with grain of salt and believe it once I see interdependent benches.
Even if the silicon is "like 7790" (and I mean the desktop variant, not the mobile version) the lack of GDDR5 and having only 64 bit memory bus would castrate that performance most likely.
I'm not opposed to 250 W TDP btw. Your average closed loop can take 250 W with sort of acceptable delta and its manageable even with realtively cheap air coolers, say, for example 212+ which is damn good price/performance.
I'm sure they're planning onboard GDDR5, like 1-2GB DDR5 onboard for 20$ extra and add the RAMs yourself ... They might have shaved off some pins to do that. PD needed alot of pins.
I would like to know who mentioned 250W TDP. They could certainly squeeze a 7950 and 3 module SR in there if they aimed for 250W TDP ... Better than a CPU+GPU though
