Really? What else did you think was major power users in a CPU?
Sure, but I still think it's quite a lot. E.g. the 4790S is 65 W / 4C / 3.2 GHz, and it includes a rather big iGPU too. I wonder how much of that TDP is consumed by the CPU vs iGPU? Let's say it's 40 W CPU and 25 W iGPU. Then they ought to be able to make a 2x40W=80W TDP 8 core CPU. Very rough estimate of course, but still way less than 140 W that Haswell-E 8 core is.
You dont need to run all 8 cores at 4GHz, you can have 3-4 cores at 4GHz+ and the rest at 3Ghz if you like to have low TDPs.
I can do that with my Core i7 3770K from 2012, im sure you can do that in 2015 with an 8Core SKU.
If you only look at the integer performance of a single Broadwell core, the improvement over the Haswell based core is close to boring. But the fact that Intel was able to combine 8 of them together with dual 10 Gbit, 4 USB 3.0 controllers, 6 SATA 3 controller and quite a bit more inside a SoC that needs less than 45 W makes it an amazing product. In fact we have not seen such massive improvements from one Intel generation to another since the launch of the Xeon 5500. The performance per watt of a Xeon D-1540 is 50% better than the Haswell based E3 (Xeon E3-1230L).
If CPU performance is somewhat important, the Xeon D is the absolute champion. A Xeon E3-1230L server with similar features (2x 10 Gb for example) will probably consume almost the same amount of power as we have witnessed on our Asus P9D board (68 W). Given a decently scaling application with enough threads or some kind of virtualization (KVM/Hyper-V/Docker), the Xeon D server will thus consume at most about 1/3 more than an Xeon E3-1230L, but deliver almost twice as much performance.
The Xeon D effectively puts a big almost unbreakable lock on some parts of the server market in the short and mid term (as Intel will undoubtably further improve the Xeon D line). It is hard to see how anyone can offer an server SoC in the short term that can beat the sky high performance per watt ratio when performing dynamic web serving for example.
According to what I've been able to find, a mask set for Intel's 14nm process consists of 59 individual masks (estimated of course). A 14nm mask set for a high performance SOC is currently around $50M about a million bucks a mask.
Now you need multiple mask sets for each spin of your silicon, even the ones that don't even see the light of production (pun not intended). The costs add up very quickly.

Whats behind the keyboard is equally as important, since this is first and foremost a gaming laptop. Here MSI has not disappointed either. Intel has finally released quad-core Broadwell parts, and MSI has shipped us the just recently updated version sporting the Intel Core i7-5700HQ processor. This is one of the new breed of 47 watt processors on 14 nm, with a base of 2.7 GHz and a turbo of 3.5 GHz. MSI pairs this with 16 GB of memory, and not one but two GTX 980M GPUs in SLI.
Broadwell has been slow to arrive in its quad-core form, but I have to say I am impressed. Intel only says it is a couple percentage points quicker than Haswell in IPC, but the new processes opens up the processor to be able to maintain its Turbo frequencies longer, and it ends up outperforming Haswell parts that are up to 500 MHz faster in our benchmarks. Its almost too bad Broadwell will be so short lived, but we shall see what the rollout of Skylake is.

Good showing for Broadwell-H. Too bad it will probably be one of the shortest lived Intel mobile chips. It was released not too long ago, most of the 17''+ notebooks launched this year are still using Haswell-H (Apple included) and Skylake-H will arrive as soon as September.
So when is this chip going to be available to buy? I wanted to build a new SFF rig in time for the Windows 10 rollout, but you still can't get the i7-5775C anywhere. Any ideas on a real release date? Also, when is Anandtech going to have the 2nd part of their broadwell review? Thanks.
release a 14" full hd ips laptop with this sweet iris pro dual core already

cheap, very balanced, low power and powerfull, should be the true bargain of this whole broadwell lineup
Skylake's Iris Pro (GT4e) won't be out until sometime in 2016. Possibly late 2016, we don't really know. If anyone really wants GT3e it's gonna be Broadwell or bust.
At the end of 2015 or at the beginning of 2016, Intel will introduce BGA versions of Xeon E3-1200 v5 chips with Premium graphics, featuring GT4 GPU and 128 MB eDRAM. The processors will have 4 CPU cores, and support only DDR4 memory.

Yeah, what's up with that?Still waiting for the Broadwell OC article from AT.
