The Performance Summary

At $199 and $285 the obvious comparison points are Intel’s Core i5 750 and Core i7 860. We’ll dive into the complete performance tests in a bit, but if you’re looking for some quick analysis here’s what we’ve got.

Single threaded performance is squarely a Lynnfield advantage. Intel’s quad-cores can turbo up more and Intel does have the advantage of higher IPC.

Phenom II X6 vs. Intel's Lynnfield Processors
  Cinebench R10 (Single Threaded) Cinebench R10 (Multithreaded) 3dsmax r9 x264 HD - 2nd Pass Left 4 Dead
AMD Phenom II X6 1090T 3951 18526 13.7 28.5 fps 127.2 fps
AMD Phenom II X6 1055T 3547 16268 12.7 25.1 fps 111.5 fps
Intel Core i7 860 4490 16598 15.0 26.8 fps 131.0 fps
Intel Core i5 750 4238 14142 13.4 21.0 fps 130.0 fps

Highly threaded encoding and 3D rendering performance are obviously right at home on the Phenom II X6. The 6MB L3 cache and lower IPC does appear to hamper the Phenom II X6 in a couple of tests but for the most part if you need threads, the X6 is the way to go.

Applications in between generally favor Intel’s quad-cores over the Phenom II X6. This includes CPU-bound games.

None of this should be terribly surprising as it’s largely the same conclusion we came to with the Athlon II X3 and X4. If you run specific heavily threaded applications, you can’t beat the offer AMD is giving you. It’s the lighter or mixed use workloads that tend to favor Intel’s offerings at the same price points.

    Unfortunately in my experience, antivirus seems hard-drive limited even on Conroe dual core processors. Reply

    I would agree. Going to an SSD will probably make more difference than adding more cores, when it comes to everyday multitasking. Reply

    You're lucky, both MSE and AVG usually hit 100% of one core both for my 1.8 and 2.33 GHz Core 2 Duos. Reply

    Frankly, the list of apps you provide would run just fine on a single-core CPU. Reply

    yep, like on my netbook with a z520 atom. AVG + utorrent + FF or chrome no issue (unless of course hd flash movies but that's another story).

    On my desktop (which is also a pretty old and crappy e4300) i also have seti@home. so basically i'm always at 100% cpu but still feel the hdd is limiting.

    Yes it makes sense... things like browsers, IM, email don't take a lot of CPU. They can easily be juggled by the OS on just a single core (or with hardware, using HT).
    More processes don't necessarily require more cores.
    I mean, I am currently running two instances of Visual Studio, a browser with 10 tabs open, Skype, Spark, Notepad++, Outlook and a few other small things in the tray or background, and my dualcore still is at 1% CPU usage, according to Task Manager, and that 1% CPU is Task Manager itself. So why would I want 4 cores, let alone 6?
    It really doesn't matter.

    I think there is something really good that could be tested here, the performance of these chips running virtual machines especially with hypervisor technology..

    Any possibility of testing these chips running either xen or vmware and seeing how 4 virtual machines react on each and how 6 react ? is the performance stable etc ? The reason I ask this is for the price point if it can run 6 virtual machines all running off of their own core or sharing cores and can maintain a good performance, it would be really worthwhile investing in these for cheap virtualisation servers..

    That's all you need to know. Time to ditch my Q6600. Reply

    Well... we haven't seen the consumer priced hex-core Intel parts yet... Everybody is comparing this to the high-end Intel parts (i7-980X is a high-end part). I'll wait to see what Intel's response is before removing them from the table. Reply

    Enjoy! the waiting game... I still doubt Intel would lower prices near AMD's 6 core do to the fact that they will be ruining their much more profitable mainstream parts.
