AVADirect's W860CU: Mobility Radeon HD 5870 Vs. GeForce GTX 285M

By

Custom system builder AVADirect is one of the few companies to offer the flexibility of multiple graphics modules within the same notebook model. We used its high-end W860CU to compare AMD's and Nvidia's highest-performance mobile graphics processors.

The AVADirect Effect

As a custom builder looking to show off its performance hardware, AVADirect packed each W860CU notebook with some of its best performance hardware. This begins with 4GB of Kingston’s DDR3-1333.

The empty Mini-PCIe socket above (with the insulation-wrapped antenna wire) appears to be where the Bluetooth controller would go on a production notebook, since the production notebook actually includes one in the base price. Two sinks hide the Intel Core i7-820QM processor and the graphics module.

AVADirect offers hard drive capacities up to 750GB, but chose instead to outfit these test samples with a performance-oriented solid-state disk drive.

The W860CU includes a 42.18Wh three-cell battery. AVADirect doesn’t offer a second internal battery, but anyone who would like to carry a spare for the original battery can add it to their configuration sheet for $123.

A 120W power brick adds 1.6 lbs. to the necessary accompaniments.

Accessories include a folder with software and documentation, a DVI-I-to-VGA video adapter, a cleaning cloth, the remainder of the tube of thermal compound, and a telephone cord for the modem.

    ... 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.

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.
