AMD Phenom II X4: 45nm Benchmarked


Prices for the Phenom II fall into a fairly narrow range. For lots of 1,000, AMD will sell a Phenom II X4 940 running at 3.0 GHz for about $275 each, while the 200 MHz slower Phenom II X4 920 goes for $235 per unit. We also compared system costs for AMD and Intel builds as well.

A comparable Core 2 Quad Q6600 system from Intel costs about $80 less than a Phenom II system. But the Core i7 is no competition to the Phenom II in this price segment, thanks to the i7’s tri-channel DDR3 RAM and its still fairly expensive motherboards.

    YAY!, The day has come! Haven't read it yet. I am excited to see what it brings!
  • firedogevan
    why focus on the q6600... wouldn't the q9550 or 9650 be a more accurate comparison given their respective locations in the product lineup?
  • dechy
    Yeah, the price comparison table should of included a Q9550, which costs same as i7 920 but with the lower mobo/ram combo price.

    Ends up being the same price as the AMD bundle, but with a good more performance... there goes the whole "AMD price/performance" aspect of this chip.

    Great review. Maybe some overclocking later? There were some pretty high claims about its overclocking potential. I'll wait for AM3 before I retire my E6750.

    Coming up soon one-shot--I was working on that one =)

    who cares about performance/watt? PRICE/PERFORMANCE is the big deal
  • The Q9xxx series would trump the PhenomII in all the categories listed above. THG, it was downright *criminal* to have not included the Yorkfield chips in your performance per dollar and performance per watt analysis.

    hey bert/tom's:
    good write up: thought id comment on i7 watts:
    "we measured the power consumption directly from the 12 volt rail that supplied the CPU", i read somewhere the only i7 core logic gets power from 12v rail, the uncore/cache part somewhere else. if this is true, you going to do another measurements?

    I'm so happy to see Intel has some competetion. While these new processors are not mind blowing, they offer some decent performance at the price given. I am sure this will lower the price of the q9400 and q9550, which is exactly what I want to see. Maybe even the i7s price will lower and maybe we will be back in the good days..where intel and amd flipped sides of the powerhouse like every 6 months..!! Good Write Up..

    On the forums someone mentioned "why did they use DDR2-800 RAM when DDR2-1066 would give better performance for the Phenom II".Wouldn't this skew the benchmarks by a little bit (perhaps 2 to 3%)?
