Sandy Bridge-E: Core i7-3960X Is Fast, But Is It Any More Efficient?

Features
By , published

Ironically, when it comes to performance, Intel’s Core i7-3960X is the real Bulldozer. Since its power consumption levels are lower than the Gulftown-based Core i7, it should also deliver amazing performance per watt as well. Is that really the case?

Benchmark Results: Matlab

With the exception of the floating point test with irregular memory access, Sandy Bridge-E clearly is fastest in Matlab, although not as strong as expected compared to the quad-core Sandy Bridge-based LGA 1155 processors.

    Aand yet more evidence that most people looking for a high-end processor will be perfectly fine with the i5-2500K or the 2600K

    I guess it just depends on what you're doing. If you have a high end workstation and are using programs that are going to utilise all 12 threads, quad channel memory and 40 lanes of PCIe, and you need that processing power then it's probably not a bad investment. Whereas for most users the 2500K or the 2600K will do fine.

    It's i7-3960x, not i7-9360x

    Correct me if I'm wrong but isn't the 6850 a Barts card? Unless I am wrong but I own a 6850.

    There is a small typo on Page 9

    "Total power used drops again relative to Cor ei7-3960X's predecessor, the Core i7-980X (Gulftown)."

    ROFL!!! Very well said!

    Nice!

    another informative, in-depth article about efficiency. great work guys!
    3960x might very well be the $1k cpu that's worth the (over)price unlike the older 980x.
    sb-e shows that both single threaded and multi threaded performance as well as efficient power use can be ahcieved by a 32nm, 6 core, 130 tdp cpu (but you gotta pay a lot for that).
    when you bring price into the equation, quad core sb i5 and i7(95w tdp) are the best way to go (i wonder how an i7 2700k fare if it was tested alongside these cpus).

    And I was so hoping Visual C++ had made it into the regular benchmark set. Sadly, it's missing here...

    Looking forward to seeing what type of Air/liquid cooled Overclocks can be achieved with these newly released processors.

  • I wanna know how it performs on DAW apps. I hope it will be included in future benchmarks.
