The Intel Haswell-E CPU Review: Core i7-5960X, i7-5930K and i7-5820K Tested
by Ian Cutress on August 29, 2014 12:00 PM ESTLoad Delta Power Consumption
Power consumption was tested on the system while in a single MSI GTX 770 Lightning GPU configuration with a wall meter connected to the OCZ 1250W power supply. This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency under 50W and 90%+ efficiency at 250W, suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency.
We take the power delta difference between idle and load as our tested value, giving an indication of the power increase from the CPU when placed under stress. Unfortuantely we were not in a position to test the power consumption for the two 6-core CPUs due to the timing of testing.
Because not all processors of the same designation leave the Intel fabs with the same stock voltages, there can be a mild variation and the TDP given on each CPU is understandably an absolute stock limit. Due to power supply efficiencies, we get higher results than TDP, but the more interesting results are the comparisons. The 5960X is coming across as more efficient than Sandy Bridge-E and Ivy Bridge-E, including the 130W Ivy Bridge-E Xeon.

Many thanks to...
We must thank the following companies for kindly providing hardware for our test bed:
Thank you to OCZ for providing us with PSUs and SSDs.
Thank you to G.Skill for providing us with memory.
Thank you to Corsair for providing us with an AX1200i PSU and a Corsair H80i CLC.
Thank you to MSI for providing us with the NVIDIA GTX 770 Lightning GPUs.
Thank you to Rosewill for providing us with PSUs and RK-9100 keyboards.
Thank you to ASRock for providing us with some IO testing kit.
Thank you to Cooler Master for providing us with Nepton 140XL CLCs and JAS minis.
A quick word to the manufacturers who sent us the extra testing kit for review, including G.Skill’s Ripjaws 4 DDR4-2133 CL15, Corsair for similar modules, and Cooler Master for the Nepton 140XL CLCs. We will be reviewing the DDR4 modules in due course, including Corsair's new extreme DDR4-3200 kit, but we have already tested the Nepton 140XL in a big 14-way CLC roundup. Read about it here.

Right. Gulftown was the 32 nm shrink of 45 nm Nehalem. However, in that case there was no associated IPC change (except AES addition in Gulftown), so in light-threaded tasks there was no performance difference between the two (except AES), so people often informally confuse the two, despite the fact that Gulftown has two more cores due to the 32 nm instead of 45 nm.SantaAna12 - Friday, August 29, 2014 - link
Good timing Anandtech!I might have missed it, but any variance at 1440?

"Intel has decided to made the lower cost Haswell-E processor ..." I think it should be /made/make.Ian Cutress - Monday, September 1, 2014 - link
Thanks for the catch, edited :)bernstein - Friday, August 29, 2014 - link
Thanks for this review. It's now clear, this platform is for an extremely narrow target audience, requiring the most computational speed on a single mainboard, requiring 4 RAM channels or 40pcie lanes but be cheaper than xeon e5 yet not need ecc.i truly wonder what prcatical application there is? i mean it can neither mission critical or scientific stuff becuase that would require ecc... gaming at 8k? (no 4k works fine on a 4790K with two titans)

video editing, 3d rendering, audio/photo work should still benefit from lots of cores.Kain_niaK - Friday, August 29, 2014 - link
Yeah until you stop upgrading and build a rendering farm that can split the workload over multiple systems. Then you just keeping buying more of the price/quality stuff. CPU's or GPU's.Brigaid - Friday, August 29, 2014 - link
"Modules should be available from DDR3-2133 to DDR3-3200 at launch, with the higher end of the spectrum being announced by both G.Skill and Corsair."Page 1. Shouldn't these both say DDR4-?

Ian - How come we didn't see any tests of over clocking with the 6 core 5930k and 5920k? I had just purchased a i7-4790k that isn't even installed yet. I am not just a gamer, I do video and photo work as well and I am constantly CPU limited. The X cpu is way to expensive, so these others particularly the 5920k overclocked might be a perfect sweet spot for a lot of people.
