Intel Xeon 5600-Series: Can Your PC Use 24 Processors?

Benchmark Results: Media Encoding And Cinebench

A four-thread Core i5-655K overclocked to 4.66 GHz takes more than eight minutes to finish our HandBrake workload, so it’s pretty impressive to see the 12-thread Core i7-980X at its stock 3.33 GHz doing the same job in almost half the time. The return on investment in upgrading to a 16-thread Xeon W5580 configuration is minimal, though the speed-up is still measureable. And switching over to the 24-thread setup is more impactful still, demonstrating how well this free application is optimized for threading.

In contrast, 24 threads is complete overkill for Xvid, which actually gives up performance as you run it on more complex hardware.

DivX is fastest on the Xeon X5680 setup, but it’s fairly clear that this one is optimized to run on fewer than 12 threads, as the Xeon W5580’s 133 MHz clock rate disadvantage is the most glaring influencer of performance here.

Optimized for up to 64 threads, Cinebench 11.5’s CPU render clearly favors the dual Xeon X5680s, demonstrating impressive scaling in the process.

In contrast, the OpenGL rendering test returns higher frame rates on the Core i7-980X, suggesting that when your workload is less processor-dependent, a more complex platform might actually be a detriment to performance.

    Or 24 Logical cores, not really Processors.

    24 threads, 12 cores.

    A+ Excellent Review.

    I was expecting an even better performance from these CPUs.The performance is still limited by the software you use.

    The Xeon 5600-series tops out with 6 cores and 12 threads, yielding 24 logical processors between two sockets. =)

    So many cpu's in task manager...do all but 1 go unused running a single threaded app? shame intel had to go this route with more cores instead of making single core with hyper-threading work faster. you should really only need 2 logical cpu's and hyper threading accomplishes it with 1.

    i have a feeling you dont understand what the word "workstation" means.

  • Hyper threading was kind of cool back in the P4 days, but now I don't see the point. Virtually nothing that >people actually use< has any benefit to see from it.. It just makes for cool screenshots imo..

    I guess what this review says is that, if you want performance for stuff you do at home you should pretty much just get a Nehalem i7 6c with some fast ram. The xeons seems to be behind on everything multimedia, much as expected.

    mheagerNot true. Hyper threading makes it so if one app gets stuck in an endless loop it doesn't suck up all the cpu and freeze the computer.The OS can do that even on a single core with no HT. Not to mention the case with many physical cores which non-HT CPUs have nowadays.
