    I"m considering upgrading my 6,1 from a stock 6 core to a E5-2687W v2 but it's TDP is 150W as compared to the stock CPU which is at 130W.

    Has anyone had any direct experience with this? I see on Geekbench (http://browser.geekbench.com/geekbench3/search?utf8=✓&q=MacPro6,1+E5-2687W+v2) there's a handful of benchmarks for the CPU but they were awhile ago and I'm not sure how much I'd use that solely as a guide.

    Thanks for reading!

    Don’t bother - get the E5-2667 v2 instead if you want to upgrade. Same turbo speed and bins. 130W TDP.

    “The E5-2667 v2 is the same speed at any core loading as the E5-2687W v2, the same cache, the same features, except it is slightly cheaper, uses less power and supports more memory. Sounds like an easy win for the E5-2667 v2.”

    FWIW I did the same upgrade and am pleased with the results.

    Another vote for the 2667 V2. I upgraded a stock quad core with one, and the difference in multicore aware apps is rather substantial.

    The Geekbench scores you've linked are of dual CPU systems, so they're Hackintoshes. You'd probably be the first do try a E5-2687Wv2 in an actual MacPro6,1. If you end up doing it, please report back. :)

    I still don’t understand why anyone would bother, unless they got the chip for free. A 2667 V2 has the SAME performance and stays within the heat envelope that the nMP was designed for.

    I have seen reports of other people doing it successfully, but I wouldn’t keep that system running 24/7 with heavy tasks.

    Thank you for your post above, you're right, I was ignorant of this information but think I'll end up with the 2667 V2, it's a no brainer. :)

    I really have no idea. :) But if I were to do it again, I'd go for the E5-2667v2 too, and I currently have an E5-2697v2...

    Interesting - why so? Single core performance?

    Yes. E5-2667v2 provides 15% more single core performance than a E5-2697v2. The 15% decrease in multi core performance doesn't really matter for most workloads. VERY few apps can use 24 threads.

    You gain heat with the W. Other than that, nothing.

    How is the 2667 in comparison to a standard 8core Mac Pro? I’m a heavy after effects user and could use each mhz on single core performance...

    Minimal. Turbos only 100MHz more. 300MHz non turbo. Maybe a couple of percent difference.

    Hmmmkay, so Probanot worth the trouble.
    I wish adobe would optimize their software for my 5 year old hardware ;)

    I upgraded my quad core with the 8 core 2687 v2 recently. I have run intensive benchmarks on the machine in the past 2 weeks since the upgrade. No issues with heat, idle is 3 to 4 degrees higher than the 4 core. I use it for running concurrent multiple linux vm's and super happy with the bandwidth and performance. With my current work load the cpu speed does go up to 3.8ghzroutinely due to turbo boost. The caveats the small main board is delicate and the bolts connecting the cpu to plate were extremely tight. So be gentle while upgrading it.
