Power Consumption

Power efficiency remains important to PC users and Intel and AMD have both made great strides to improve power efficiencies. Today we will be looking at a few high-end desktop processors on our Watts Up Pro ES power data logger on the three platforms with each running Windows 8.1 on the balanced power option.

Benchmark Results: The Intel Core i7-5960X has much lower than anticipated power numbers, which is great. We double checked out power numbers on both the Watts Up Pro ES and Kill-A-Watt power meter because we thought something was wrong on the X99 platform. It looks like Intel Haswell-E has a very efficient idle power efficiency as we were right around 60 Watts at idle on the ASUS X99 Deluxe motherboard with UEFI 0601 along with a 16GB kit of DDR4 memory running at 1.2V and a GeForce GTX Titan video card with the latest GeForce 334.79 beta drivers along with the Corsair AX860i digital power supply. When running Prime 95 we hit 211 Watts and then when running 3DMark we hit 302 Watts. The Intel Core i7-4960X was run on the ASUS P9X79-E WS motherboard, which is known to be slightly power hungry with all the extras on it and idled at 99.8 Watts and hit 272 Watts in Prime 95 and 326 Watts in 3DMark.

  • Price of DDR4 is bad I bought 32 GB will wait on the other half .

  • I ordered a i7 5930k for my Haswell-E Build, hopefully it arrives by this weekend but for me I just cant justify the cost of the 5960X. 2011-V3 socket will have plenty of new chips coming out during its life span so I expect to see 8-core chips fall to the $400 range in the next year or two. I’m happy with my 2500k but just have the itch to upgrade and would like to to run crossfire 290s now that they can be had for $250 and my current motherboard is PCI-E 2.0 and will run then 8x 8x, plus I could use the extra encoding speed of the new Haswell-E chip. Anyways I’m excited!! great review as always!

      Sorry pal, I’m from the future and I have to tell you, your assumption is wrong. Looking at the price of the i7 6900k Octa-Core makes me laugh when I read your comment. Its about 1,100$ right now. I don’t think Octa-Cores will drop below anywhere near 400$ or 500$ within the next 5-6 years.

    Do you know if PSU Corsair AX850 can handle 5960X at 4.4-4.6Ghz?

    • yeah, it sure can

    • A friend had one overclocked at 4.4GHz with a 780ti overclocked to I think 1120mhz, and he was drawing about 550 watts at full load.

    Next year Q4 the regular Chips will be out and run DDR4 on new M.B, by then the Ram should come down in Price. No time date only rumor that a 3.5 6 core for 350$ will be the high end. I’ll wait.

    You’ve got remnants from G3258 pages in the Overclocking section and likely elsewhere, but that’s the only page I read.
