Final Words

Today's conclusion is no different than what we've been saying about AMD's CPU lineup for several months now. If you're running applications that are well threaded and you're looking to improve performance in them, AMD generally offers you better performance for the same money as Intel. It all boils down to AMD selling you more cores than Intel at the same price point.

Applications like video encoding and offline 3D rendering show the real strengths of the Phenom II X6. And thanks to Turbo Core, you don't give up any performance in less threaded applications compared to a Phenom II X4. The 1090T can easily trump the Core i7 860 and the 1055T can do even better against the Core i5 750.

You start running into problems when you look at lightly threaded applications or mixed workloads that aren't always stressing all six cores. In these situations Intel's quad-core Lynnfield processors (Core i5 700 series and Core i7 800 series) are better buys. They give you better performance in these light or mixed workload scenarios, not to mention lower overall power consumption.

The better way to look at it is to ask yourself what sort of machine you're building. If you're building a task specific box that will mostly run heavily threaded applications, AMD will sell you nearly a billion transistors for under $300 and you can't go wrong. If it's a more general purpose machine that you're assembling, Lynnfield seems like a better option.

    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 .
