General Performance with the X72D

This is where things are going to get interesting. With the 5470's 'roided out 750 MHz core clock and a 2.1 GHz triple core AMD processor on tap, the X72D should hopefully perform fairly well in our testing suite.

Unfortunately, while the 500 MHz core clock advantage the AMD Phenom II N830 has is enough for it to beat the Phenom II P920, three 2.1 GHz cores just aren't enough to tackle the pair of hyper-threaded 2.4 GHz cores in the Intel Core i3-370M. Intel's chips have a substantial advantage clock-for-clock, keeping the third core of the Phenom II from making up the lost ground. In order for that third core to really matter, the Phenom II needs to be running at clocks closer to the Intel competition, which unfortunately just doesn't seem to be possible with a 45nm process and Phenom II architecture.

    FYI

    There is a pricing row on the first page table, but the price isn't listed.

    "There's still a major stumbling block for AMD in terms of power consumption, though: an AMD-based notebook has to power both a northbridge and a southbridge, while most of this functionality is either handled by integrated hardware in Intel's mobile processors or by the single power friendly HM55/PM55 chip."

    Considering that there is a separate, 45nm chip fitting the exact definition of the traditional laptop northbridge chip in the dual-core Core iX CPU package, and that the Core 2 platform, with its multiple "inefficient" and "obsolete" chips still seems to be untouchable in battery life, that statement is riding a fine line between silliness and misinformation.

    It doesn't surprise me one bit that AMD's laptops tend to use a bit more power. That's just what happens with a more complex GPU and more CPU cores. Why that would be more dependent on nearly identical northbridge and southbridge functionality is beyond me.

    Seconded. Reply

    I've updated the text to make it clear that it's not just having an extra chip, but having three AMD chips (which have traditionally not been as power optimized) vs. two Intel chips is a real concern. The AMD CPUs have always used more power (at least post Pentium M), and I don't think either the NB or SB is particularly power friendly. They're not horrible either, but having two chips doesn't do AMD any favors. Finally, toss in process tech and the result is less than ideal battery life. Reply

    I really don't know why AMD calls these Phenom II's when they lack an L3 cache which puts it a lot closer to the Athlon II chips. It can get confusing and hard to tell each mobile cpu apart that AMD markets for advance users to tell apart let alone the avg pc user lol. Unlike their desktop chips line which is pretty cut and dry, their mobile chips on the other had are all over the place. You have the mobile Phenom II x4/x3/x2, the Athlon II X2/ Neo X2, the Turion II X2/ Neo X2 (which are basicly lower clocked Phenom II mobile cpu's now.) and the AMD single core V series that are all based on the same Champlain 45nm architecture.

    Same reason why Intel calls Lynnfield i7. Marketing BS. Reply

    Yeah but in the mobile sector Intel's chips are a lot more clearer then AMD's to understand. Core i7 highend, Core i5 mainstream, Core i3 budget, Reply

    It's sort of like Back-to-the-Future III, it's really less like B2F II and more like Feival Goes West. Reply

    Since this is a laptop offering SATA 6Gbps, i strongly suggest you run a bench round with C300 128/256GB in it.
    It would also be nice to see the PCmark scores of that compared to the original configuration and the competition.
    Storage performance can be a real problem in laptops, so this could be a key selling point, at least for the version K72DR that does not include the mostly pointless price addition of a BD player.

    "Processor AMD Phenom II N830
    (3x2.1GHz, 45nm, 1.5MB L2, 35W)"

    Why do you state it as 3 times 2.1GHz? The frequencies of the cores don't add up. 3 cores don't even mean linear scaling vs. 1 core. So technically it's incorrect.
