Is CPU technology topping out? I mean as far as the cpu performance itself, not integrated gpu performance or other things like what Haswell is focusing on.
With Haswell, we can expect another ~12.5% increase in IPC, and the same 19% reduction in power consumption Ivy Bridge brought.
How will Haswell be able to reduce TDP by 19% without any node shrink?
Simply put, no.
Bloomfield had a TDP of 130 W. The Core i7-975, a Bloomfield CPU, ran at 3.33 GHz. A Core i7-2600K or i7-3820 can run at 4.5 GHz (100*45 or 133*34) without breaking that level of power consumption. 35% increase in clock speed and ~12.5% increase in IPC while held at the same level of power consumption. That's a 51.875% increase in performance/watt. That's certainly a huge jump.
Also, the point isn't to compare an overclocked CPU to a stock CPU. An i7-2600K will pull around 130 W maximum under full load when at 4.5 GHz. An i7-975, from what I recall, pushed the 130 W TDP at stock settings.
With Haswell, we can expect another ~12.5% increase in IPC, and the same 19% reduction in power consumption Ivy Bridge brought.
What consumer application will ever need more computing power? Most people run web browsers, watch some videos, use Office apps, maybe play some crappy Flash games...
The enterprise market will drive technology innovation, but I think the PC has come as far as it needs to.
Dude, there is ONE thing that drove hardware innovation to where it is today. That one thing is GAMES, period.

I disagree.
Very much so topping out .. think moores law .. you're talking about 12.5% increases where you should be talking about 100%.
It seems like we need to conquor a new parallel programming paradigm before the next fase of 'moore' can proceed.

If Intel and AMD were allowed to work within a 150W TDP in the mainstream space today, they could push performance significantly harder than they do now.
The main competitor for Haswell-EP will not be AMD with their unannounced successor of the yet unannounced Abu Dhabi Server CPU (confused yet?), it will be a combination of NVIDIA Maxwell GPU paired with an Project Denver-based Server CPU.
They are . Haswell-E will have up to a 160 watt TDP.

That's not mainstream. That's the workstation platform and the chips will cost you $500-$1000.

So what? This will be an enthusiast CPU on an enthusiast platform. A 160w TDP doesn't belong and would not work on the mainstream platform. Think of the pin count and power delivery.
