Intel Core i7-3930K And Core i7-3820: Sandy Bridge-E, Cheaper

By Chris Angelini
published

Core i7-3960X is undeniably fast. But at more than $1000, it’s hardly an option for most enthusiasts. We got our hands on the Core i7-3930K and Core i7-3820 to gauge their overclocked performance and determine if they’re able to best the flagship part.

Benchmark Results: Crysis 2

Minimal variation between platforms in this graphics-bound title is expected. There’s really no reason to highlight any particular result. When it comes to Crysis 2 (and a single-GPU setup), any of these processors are suitable.

    This is a really excellent analysis. Clearly, I must be drinking at the wrong places because I never leave the pub with any hardware nicer than a hangover.

    So nice overclocking at 4.5ghz. I can expect that the upcoming ivy bridge unlocked series may be stable atleast 4.2 will all 4 cores active. I can't wait till Q2 next year to see benchmarks .

    Possible TYPO in the bottom graph for Dirt 3 benchmark.
    FX-8150 benchmark with no AA says "68.8" FPS. I think it's more like "48.8".

    For gaming (the high end CPU intensive), is there any noticeable difference between the 2500k and the 3960X?

    If by "noticeable" you mean "perceivable to mere mortals", then no.

    If you can in fact notice the difference between 105 vs 110 FPS, then you are a god, and you deserve only the best.

    I bought the i7-3930K with 32GB of DDR3 1600 RAM last week and assembled a couple days ago. I have two Kingston 120GB SSDs in RAID that have been benched on my system at a theoretical 1,100MB/S Read and 1,300MB/S Write. Coming from a Pentium D 3.0GHz, this was like night and day. My renders went from 40minutes to 1minute. I'm not overclocking purely for the fact that this thing's a beast already and I'm doing high-end 3D work using Maya, Photoshop, After Effects, Video, etc. Also - I like the peace and quiet.

    Intel did an awesome job with the SBE line - despite the fact that we're missing some wanted/promised features (native support for USB and PCI-Express 3.0. I'm waiting out for the PCI 3.0 cards before I upgrade my graphics... curious if the Asus P9X79 Pro will hold it's promises.

    Thanks Chris for reviewing this processor. I felt like I went out on a limb getting this processor over the Extreme, but the $600 was well worth it.

    spunky,

    Glad you're enjoying. You do, actually get PCIe 3.0 support, but no USB 3.0, unfortunately.

    Dacatak,

    Yup, typo--fixing now!

    the only good reason to get X79 is the more ram .. u can get cheap 32G ram system , or go for 64G of ram and enjoy a ram disk

    it is a good thing

    The Overclocking Sandy Bridge-E On A Budget page states, "With all of that said, 4.5 GHz was rock-solid down at 3.61 V". I'm pretty sure you meant 1.36 V.

    Indeed, fixed! At 3.6 V, we'd have dead Sandy. :)
