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.

Just like with anything in life, there are some people who will pay a premium to have the best of the best. This is exactly that.oranos - Sunday, August 31, 2014 - link
As a matter of fact, for the next generation (nvidia 9xx series and amd xxx) in quad sli/xfire setups, this chip will allow more bandwidth through the PCI-E lanes. So for the top 1% of setups this chip does matter.mlambert890 - Monday, September 1, 2014 - link
no it wont. my p7x79ws with 3960x and tri sli titan has 40 native pcie 3 lanes. sb-e has 40 lanes and pcie 3 support. advanced x79 boards with current bios fully support.this is a non upgrade honestly (x99) vs a high end x79. all you really get is usb3 and sata 6Gb/s native vs third party integrated (BFD), and the mixed bag that is ddr4

Very strangely, tomshardware has the 5820 beating out the 5930 and 5960 in gaming benchmarks. The test platforms here and there are very different, but for a start it would be great if you guys could also show us some results with a single GPU for the 5820 and 5930.TiGr1982 - Tuesday, September 2, 2014 - link
IMHO, tomshardware messed up something here - there is no physical reason why 5820 can beat 5930, because they have the same core count and cache structure, but 5930 has higher frequencies and 40 PCIe lanes vs 28 lanes of 5820.Fedor - Wednesday, September 3, 2014 - link
Yup, I'm leaning towards the same conclusion. It's a shame that most reviews do not cover anything but the highest-end chip, but between anandtech, tomshardware, 3dguru and another review I found in Belgian (the graphs were self-explanatory at least ;) only tomshardware has that anomaly, so I'm inclined to agree.Bombreezey - Monday, September 1, 2014 - link
These cpu's would be more beneficial to higher resolution gaming. I love how people are trying to compare this new cpu's to the i5-2500k. There is nothing wrong with the 2500k when gaming at 1080p but when the time comes when people start witching over to 4k gaming when it becomes more affordable your 2500k is gonna struggle big time. Like people have said earlier, there is more to computing than gaming. These cpu's will be vastly faster at video converting/rendering, and other cpu intensive applications when compared to older series of intel cpu's. On another note I see people are complaining about heat because of the high tdp... when there are more cores its gonna need more power......soooooo get a water cooler and problem solve :). At least the tdp isnt 220watts like amd 8 core cpu. So 150watts is pretty fair for a intel 8 core cpu that straight up murders a AMD 8 CORE CPU.untoreh - Friday, September 12, 2014 - link
amd octa core costs 1/4 of the intel octa core, if not 1/5.soldier45 - Monday, September 1, 2014 - link
Was thinking of moving from my 2600k at 4.8 to the 5930k but really not worth the $ for a 20% boost in certain apps and little to no improvement in gaming.ryanbrod - Monday, September 1, 2014 - link
Why is it that every review of the haswell-e chipsets doesn't even make an attempt to saturate more then 16 pcie lanes... The whole point of the haswell-e chips in my opinion is the extra PCIe Lanes for tri and quad sli/crossfire set ups. dual gtx 770s is a joke of a review if you ask me. Put in at least 3 of them or dont do a gaming review at all because its going to be less then 2% difference in performance from regular i7s.
