General Performance
SYSMark 2007 & 2012
Although not the best indication of overall system performance, the SYSMark suites do give us a good idea of lighter workloads than we're used to testing. SYSMark 2007 is a better indication of low thread count performance, although 2012 isn't tremendously better in that regard.
As the SYSMark suites aren't particularly thread heavy, there's little advantage to the 6-core Sandy Bridge E CPUs. The 3770K however manages to slot in above all of the other Sandy Bridge parts at between 5 - 20% faster than the 2600K. The biggest advantages show up in either the lightly threaded tests or in the FP heavy benchmarks. Given what we know about Ivy's enhancements, this is exactly what we'd expect.

"there's also the question of which one (CPU or GPU) approaches "good enough" first."I was worried that my A6 3420 laptop would feel sluggish in windows and general tasks, especially compared to my 2500k desktop system. However, I've been very surprised and think it works just fine in windows.
I was also very impressed that the iGPU lets me play most newer games comfortably. I was able to OC my A6 3420 on my Samsung 3 series to 2.0ghz. It runs Crysis 2 on low at 1366x768 in the 25-30 fps range. Now to me that is not really playable, but I was surprised it could even run it. Other games like SC2, Arkam Asylum, CSS, WOW, have all ran like a champ. Most of them even on medium settings!
So I think if you want a cheap laptop (mine was $399), and you want the ability to play some games while still doing general tasks well, we have already hit that "good enough" stage on the CPU department. It will be interesting to see if Windows 8/Metro does anything to change this.

You are dead wrong. I need fast CPU for my work but need or care about the gpu. You realize people do more than game, right.SquirrelPunch - Monday, April 23, 2012 - link
Could not disagree more.In fact the majority of power users do not need a powerful GPU, just lots of RAM and fast CPU.
Graphics designers: All 2D mostly, do not need powerful GPU.
Video Editors: Same as above.
Software developers (not games): same as above
Standard CAD: No intensive 3D models involved.
Most also don't care for multi-monitor setups, or the 2x that HD series will let you use.

Intel needs another Larrabee. It keeps cobbling together these graphics cores, which are always well short of the mark. Either Larrabee 2 or licence from Nvidia, but something has to be done about it in the long (possible mid) term. It makes perfect sense and, to me anyway, has the air of inevitability about it.Why not take the plunge?

I find it odd the AMD A8-3870K was left out of the power consumption section, but is in the others.I ran a quick test and my kill-a-watt meter read 126Watts max x264 HD v5.0.1 which bests all of them
It also idles at 34.5 watts which blows them all away by a very large margin. The best is double what the AMD A8-3870K idles.
