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.

    Hey, found a typo, on the AMD Turbo page:

    "While mainstream CPUs are down at 65nm". I think you meant 65w.

    there's also an "i7 670" in one of the charts on the first pages, which should clearly be an i5. Reply

    nm refers to nano-meter and 65nm is a technology node. So, the processor manufacturing has been rolling down. For example, 250nm to 130nm to 90nm to 65nm to 55nm etc...

    It is not a typo and was mentioned correctly. :)

    Chandu naanna, if you take a look at the context, i.e. the sentences before and after the "wrong" sentence, you should be able to understand why it should be "W" instead of "nm".

    "High end desktop CPUs now spend their days bumping up against 125 - 140W limits. While mainstream CPUs are down at 65W. Mobile CPUs are generally below 35W. These TDP limits become a problem as you scale up clock speed or core count."

    Ardhamainada? :D

    As usual Anand, the article was great and really helped with figuring out where I am taking my wife's next computer. I was tempted to go AMD this time around for her next PC, but after reading this I believe I will stick with an Intel solution. Thanks man!

    You would have to be insane to pay $1000 for a chip that may be good for gaming. at $199 with slightly lower performance its a no brainer. When I build a system, I don't care if the frame rates etc is 10 to 15% better. Who cares ; the chip is fast and I have not problems playing high end games. I have no special setup and it does everything that my friends I7 can do. Good for me I get more pc for the buck . Go ahead and go broke buying just a motherboard and cpu when I can get a modern motherboard a cpu, 6gigs of ddr3 1600, a 1tb hd and a dvdrw. More for me. Reply

    i compared intel and AMD from almost AMD start ( K6 II ) CPU , i believe that AMD did not change their Policy much : they still offer more for less , with one different , in that time the market was also different from today , now a days , you can easly found all the hardware you need and it's compatible and works with AMD ,
    it's accurate Say : it's not about absolute Perf , it's about pref at a given price
    and in this , i think AMD wins .
