The Economic Problem

For the consumer, AMD's pricing strategy is incredible. For AMD and its shareholders however, the pricing is a bit tough. The Phenom II X4 940 is priced similarly to the Core 2 Quad Q9400, a chip that is 36% smaller than AMD's offering. The Phenom II X4 810 goes up against the Q8300, again, a chip that's 36% smaller. The Phenom II X3 720 is even worse shape; AMD is selling a chip that's 258 mm2 at the same price Intel sells a 82 mm2 chip; that's a 68% smaller die at the same price.

AMD CPU AMD Die Size Competitive Intel CPU Competitive Intel Die Size Intel Size Advantage
AMD Phenom II X4 900 series 258 mm2 Intel Core 2 Quad Q9xxx/Q8xxx 164 mm2 36%
AMD Phenom II X4 800 series 258 mm2 Intel Core 2 Quad Q8xxx 164 mm2 36%
AMD Phenom II X3 700 series 258 mm2 Intel Core 2 Duo E7xxx series 82 mm2 68%

 

AMD in many cases delivers greater performance than the similarly priced Intel CPUs, but not nearly a large enough performance gap to make up for the difference in die size. Again, great for consumers, but potentially painful for AMD in the long run. As yields improve AMD should be able to make more of these cores members of the 900 family, but without a separate, smaller die there will still be economic inefficiencies at the lower end.

    Intel Core i7 920 Nehalem 2.66GHz not 2.8 you put def procer in test and if overclockd you write oc...
    I am sure that intel is better but no so way better
    and in my opinion in the last 2 years you fav intel and nvidia more for what i am sure u have good reasons.Why i think so becas... you point just the bad sides of amd and the good of the other side on price preformance cpu mainbord you name it the diff between amd intel is tiny or amd is better.And another thing i live and work in germany and from 1000 pepole maybe 1 has core i7 pepole dont have money for maybe litle better cpu wich by the way has no software or appp maybe 5 or 10 and you compare that with ddr 2 platform from amd come on now

    Do some math with me:

    * 790FX/GX motherboard 125 USD
    * Phenom II X3 720 BE 145 USD
    * 2x2GB DDR2 800 MHz 50 USD
    * Radeon HD 4850 150 USD
    * Power supply 550 Watt 55 USD
    * Chassis 50 USD
    * 500 GB HDD 55 USD

    Grand total: 630,- USD

    Phenom II does not fix XP's performance problems with Phenom's CnQ, btw. Huge performance loss. Saw it first hand. Reply

    It is fixed on Vista and Windows 7 though... also, you need to load the new CnQ driver in XP, if you do, it works there also. Reply

    The "new" XP driver appears to be from 2007. Reply

    I use a 690G based gigabyte motherboard. Gigabyte just posted new BIOS to support these AM3 CPUs (along with AM2 and AM2+) and have been wondering what would be the performance hit from using an older motherboard with slower HT speed?

    A nice review would compare the same AM3 (plus some AM2+) Phenoms on AM2, AM2+ and AM3 (wiht DDR3 Ram). This way people who only want to upgrade their CPU would know what to expect.

    After all that's what AMD have in mind for their backward compatibility of these chips.

    Thanks.

    HT is what connects the processor to the rest of the system. High HT speed seems to be most important for multiprocessor servers and systems that use an IGP. The RAM is directly connected to the CPU, so no bottleneck there. So I doubt you'll see any tangible performance loss.

    The clear cut recommendation is Phenom ..becuase its smoother :) Reply

    Unreal. I mean look at where the now ancient Q6600 still ranks compared to AMD's latest and greatest. *sigh*

    I don't want an Intel monopoly. I don't want the only choices to be Intel and Microsoft. That's not a world I wanna live in! *Loads pistol*

    Thanks for such an informative review!

    Though 790FX/790GX is very good, I think 780G with SB700 would be a better combination for X3 720/710 considering its lower price. I've to admit I may take this upgrade path. Anyway, thanks for your hard work.
