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.

I'm guessing you don't do much animation? :) Even though many of my renders only run around 10-20 minutes max, when you do a 30s animation, you can multiply that rendertime by 900... Even for a minute a frame (which is fairly fast), that's still 15 hours.But I think the main draw for people on X58 like us, is the newer platform. X58 is really low on modern features, it came out at an awkward time. No native USB 3.0, no 6Gbps SATA, no Thunderbolt (which might be relevant in the future), no PCIe 3.0, and no support for the newer standards coming out with Z97.
Also consider DDR4 is going to be the standard going forward, so investing a lot of money in 32-64GB of DDR3, even at the lower prices, just seems like throwing good money after bad.

You are right! When I talking about a render, I am talking about exporting a music project to separate wave files (one per track). You can either record while playing it back or you can render it. Most VST plugins have a render mode as well so the end result is sometimes quite different. Not necessarily better, but different. And recording is done in real time, so sometimes a render is a lot faster.kevith - Friday, August 29, 2014 - link
Right on!bebimbap - Friday, August 29, 2014 - link
the 31% is at the same frequency.being able to do double the work with the same amount of energy or the same work with 1/2 the energy is a big deal.
imagine if cars could do that... 2x the horsepower but same amount of gas... or the same mileage at 1/2 the gas

ive been happily on my x58 i7-980x for 4 years and honestly if my chipset wasn't missing so many modern features i wouldn't even upgrade. But the lack of pci-e 3.0 lack of sata 3 lack of usb 3.0 are just becoming a pain in the ass. ur circo 2008 is wrong too i know because i got the i7-980x right when it came out and it was in 2010 not 2008 so that would be 100-110% over 4 years.I really want an ultra m2 pci-e 3.0 x4 drive as my main os and application drive. Can't wait to pop in a 1TB samsung sm951 ultra m2 drive. Also cant wait for the 16GB DDR4 sticks to start showing up. 8x16GB 128GB of ram, can you say 112GB ram drive and 16GB ram for the system. It's gotta be awesome working on video editing with your entire video in a super fast ram drive. My memory and storage is what's going to boost the performance for me gtom my x58 the cpu will too but not like the ultra m2 ssd with like 1400MB/sec read and 1200MB/sec write

I recently went from an i7-950 to a i7 4770. It's made for a solid bump in performance. I notice it particularly in navigating game menus that used to be a little sluggish before.Railgun - Friday, August 29, 2014 - link
Sold! As I'm still on Gulftown, this is just what the doctor ordered. The i7-970, IMHO, has held its own for four years, at least for my needs. This will be one helluva shot in the arm.PEJUman - Friday, August 29, 2014 - link
with you on this. I actually sold my gulftown with 48GB last year for the 6xSATA on z87, The x58 + gulftown is one heck of a system. If I don't already have the 4770k, this 5960 or 5820 would be extremely difficult to resist.I actually tempted to mount the mobo+CPU+intel sink on the wall instead of selling it, it was a piece of computing history.

If i remember the weight of that particular heatsink, you would need a sturdy mount for your wall... thumbtacks do not applyLaststop311 - Saturday, August 30, 2014 - link
48gb on gulftown thats strange considering gulftown supports 24gb ram. http://ark.intel.com/products/47932right on intel's page. i sense a fibber. Why lie about what pc u have?
