We didn’t have a new-enough Core i7 notebook on hand to compare to AVADirect’s Clevo W860CU build, but we did have a reasonable configuration for a mobile-to-desktop performance comparison. Our recent Motherboard Shootout used the same-generation graphics driver, 64-bit Windows 7, and a Core i7-920 that just happened to have the same top turbo speed (3.06 GHz) as the i7-820QM used by these notebooks. Further details of the desktop system can be found in that article’s test settings page.

One place the desktop Core i7-920 will always beat the mobile Core i7-820QM is when all four cores are loaded, because the mobile processor starts with a lower “standard” frequency and uses more aggressive Turbo Boost modes to catch up to the desktop part. Fortunately, for comparison purposes, a few of our benchmarks are capable of applying this level of CPU load.

    ... do they have AMD CPU's too?

    How many partners use Clevo laptops and just rebrand them?

    I'm a little confused why you'd choose an i7 920 to compare with a different platform, but maybe it's because I don't know the mobile platform that well.

    But, if it's like the P55, which it seems to be, there's the added uncertainty of the architecture thrown in.

    Particularly with PCI-E being implemented differently, you might be seeing the inferior implementation of the P55 architecture responsible for a small amount of the relatively poor mobile performance. Since this implementation needs to multiplex the memory bus of the processor, you can run into situations where there is contention.

    I doubt it's significant, but I'm curious why you wouldn't want to make a comparison with a more similar desktop platform. Was it because you couldn't get an unlocked Lynnfield to get the clock speeds for the processors the same in Turbo mode?

  • This doesn't make much sense to me... if a 5870M chip = roughly a 5770 desktop chip and a 285M = roughly an 8800gts.. why is it not completely spanking it? we all know 5770>8800.. by a rather large margin! what could be the cause of this?

    Tom's, you should show your power usage results to AMD and ask for an explanation, on why a lower rated part is using more power.
    Granted, with a 45W CPU and 50W GPU, 30 mins is expected on a 40W battery if fully stressed.

    It's not "mobile gaming" at all.
    So, is there any reason to own such notebuook?

    I liked this article because I found it so darn relevant... I actually have this same Clevo Laptop, with the 5870 and 8 gigs of RAM.

    The GTX 285M was a $50 premium over the 5870, and I am glad I chose to stick to the 5870. It is kind of strange one would pay more to have less performance. I guess thats what fanboyism are all about?

    anamaniacHow many partners use Clevo laptops and just rebrand them?Lots. Mine is a Sager 8690... which is a rebranded Clevo W860CU...

    I have seen this model at other sites as well.

    Looks more like a bottleneck then anything conclusive. The results in nearly all the tests were close, yet 1 of them should have been clearly ahead.
    I think an ASUS JH73-A1 verse this would have been more interesting as its a bit cheaper for better parts.

Was it because you couldn't get an unlocked Lynnfield to get the clock speeds for the processors the same in Turbo mode? Exactly. Besides, Tom's Hardware has already seen that clock-for-clock, Lynfield games at least as well as Bloomfield when a single card is used. If nothing else, the comparison favors the mobile solution's lower power consumption.
