So... dat 8W Haswell chip?

Hm. Methinks the list is suspect.

The socket change is due to incompatibility between old and new processors. Sandy and Ivy are close enough that they can share, and get away with bios updates alone. Sometimes the CPU can still operate, but not take advantage of some features.

In this case, I suspect the VRM change alone is enough to make Haswell incompatible with the 1155 architecture. It's sort of like going from SDRAM, to DDR, to DDR2, to DDR3, and each card having a different notch or pin count because they are incompatible.

AMD has turned to more of a budget minded company, and their product line reflects it. You can build a new AMD system cheaper than Intel, and then a year later buy another CPU (still cheap) and get an upgrade. With Intel, if you built a Sandy system you'd have paid a big premium to get a new Ivy CPU, and for very little if any performance increase. However, AMD still has nothing to compete with the Sandy CPU, even all this time later, so there isn't much argument for AMD's upgradability.

...As I type this on my bulletproof 7 year old AMD system because my 1155 motherboard is being RMA'd for the 2nd time.

Well, Haswell will finally be what I think I'll jump on.

I'm done with the 'flagships' for now and see no need for the 2011 for me.

Still hanging on with my 920 C0 X58.

But I will jump on Haswell and it can't ship soon enough. I've got the shakes.

List doesn't have any -M or -U. Its most likely complete for what it covers, desktop i5 and i7.

Features.

Even with Z77 Asus said they wanted all P8Z77 boards to overclock the same, regardless of price.

Actually I didn't notice this before, but all those CPUs have 4600 graphics. Even the one 2 core model. That's a pretty big deal.

I wonder if all desktop i3s will have it too. If they do, Intel will really have stepped up their graphics game compared to IVB and put GPU horsepower where its needed.

The higher TDP is curious, it'll be interesting to see power consumption numbers...and OC'ing capability, which could go either way. If this spec sheet turns out to be true, it'll be even more reason to wait for benchmarks to see how AVX2 and TSX improve things (or, which programs take the most advantage of them in the upcoming months).

That's a good point, it'd be nice to have some of the "high end" IGP on an i3, good catch.
(of course, that the real high end (Crystalwell) is being saved for mobile...but still, more EU's for i3 would be great)

Interesting...

of course TDP is higher, its still on 22nm just like Ivy, and intel significantly increased iGPU without lowering CPU clocks... Frankly, I'm surprised its only 84W and not back up to the 95W of Sandy. Granted, this is good news because I couldn't care less about the iGPU for a desktop rig, and really would rather prefer they don't include it at all in their K series so that the chip is focused solely on providing the best CPU performance possible

And the i5's need HT, why would they remove that feature? Is this because they have 4 physical core instead of 2? Meh, I'll pass on this if those are the features you get for that TDP

K series on 1155 never had VT-d before, and the 4 core i5s have also never had HT...HT is pretty much the one feature that truly sets the desktop i7s apart from the i5s in terms of performance. While its true that the i7s have a bit more cache, HT is by far the biggest difference maker, not that its really that much of a difference anyway as its hard to justify the increase in price to go from the i5 to the i7.

And, again, the TDP increase is pretty much solely because of the focus intel put on improving the iGPU, so unless you're going to use the iGPU, its not going to be worse than Ivy.
