GeForce GTX 480M: AVADirect’s W880CU Is Packing The Heat

Inside The W880CU

Removing the battery reveals the second hard drive bay and a Mini PCIe card bay with a mirror-finished cover that, in turn, reveals the type of camera used for today’s photographs.

The larger cover hides the first hard drive, factory-installed wireless modules, two mid-sized cooling fans, and a fairly elaborate heat-pipe arrangement. Notice that the component on the right uses both fans and has two-thirds the total number of heat pipes.

A look at the size of Nvidia’s GeForce GTX 480M gives us some clue as to why the majority of system cooling serves this part. At barely more than half the size of the GPU, Intel’s Core i7-820QM also gets by without active cooling for its memory.

Also seen above are the CastleNet BTC04R Bluetooth module, Intel Ultimate-N 6300 Wi-Fi card, and a pair of Kingston’s KVR1333D3S9/K2 memory modules.

Matching the performance configuration of its previous machines for today’s tests required AVADirect to include a Corsair Nova series 128 GB SSD, in addition to the previously-mentioned CPU and RAM. A full range of alternative components allow AVADirect customers to seek even higher performance, or lower cost.

One might think that a notebook with a bigger screen and higher-wattage graphics solution might come with a larger battery, but Clevo picked the same 3800 mAh capacity for the W880CU as previously tested in its 15.4” W860CU.

Gaming is going to require a wall connection, and that’s where the W880CU is really upsized. At 6.7” long, 3.3” wide and 1.7” thick, its 180 W power brick is at least thinner than its masonry namesake.

    I think that sums it up.

    Quite a surprise on the power consumption...

    That's a crazy heat pipe setup...

    Agree on the naming thing on the last page, that would be helpful.

    Great review.
    Before its launch,it was rumored that it will have a much higher power consumption than 5870M, but now it seems they are close

    "Notice that the component on the left uses both fans and has two-thirds the total number of heat pipes" Ummmmm if I'm looking at the picture correctly the GPU and the majority of the heat pipes are on the Right, you may want to retype that.

    are there no temperatures for gpu in article or i missed it?

    The funny thing is, AMD actually DID use the naming scheme you like in their LAST generation of mobile GPU's. The Mobility 4850 matched the standard 4850's number of stream processors, albeit with lower clock speeds. Same with the Mobility 4870 and Mobility 4870x2.

    They changed it in response to Nvidia's naming scheme, which is a shame. I liked the matching of desktop/laptop performance to names, too. :/

    The difference of around 50W under full load is a big deal! Fortunately, you only SEE that difference under full GPU load.

    Excellent observation, thanks! I was flipping it back over in my mind, since it's upside down, but that doesn't work for describing photos!

    FurMark reports GPU temperatures in the mid 70's, but I'm not certain how accurate that reading is so the information wasn't included.

    Yes, I've never been one to make a big deal of underclocking, but when NVidia named its G92 as a GTX 280M, I reached my personal limit.

    With that kind of money i can get both, a good gaming desktop and a decent gaming laptop (with 5870M). Oh well...
    But its nice to see nVidia catching up to ATI... Let the price wars begin so i canget my second 5850 ;-)

    Many people were praising the Mobility Radeon HD5870 for its relatively low power consumption, especially in comparison to the spec sheet for the GTX480M, which described Nvidia's latest high end mobile part as having a TDP of 100W. In fact according to the spec sheets the Mobility HD5870 uses significantly less power then even the GTX285M at full load, 50W in comparison to 75W. However, it quickly became apparent that something wasn't adding up.

    http://www.tomshardware.com/reviews/avadirect-clevo-w860cu-mobility-radeon-hd-5870,2615-11.html

    What many of the people who were bashing the TDP's of the GTX285M and GTX480M didn't understand was that ATI and Nvidia calculate TDP differently. ATI only figures in the power draw of the GPU itself, while Nvidia measures the entire board including memory. So direct comparisons based solely on the numbers provided by the spec sheets won't accurately represent real-world differences in power consumption. In many cases the actual power draw of these mobile parts is much closer then the official spec sheets would have you believe.

    How hot does this thing run? Manufacturers need to stop focusing on 'faster, faster' and more on 'cooler, cooler' now

    No.. the chip itself IS the heat :O!

    Price is being overlooked here.
    GTX 285M is 75$ more than Mobility 5870 so I believe I can buy 2 5870 for the price of one 480M.

    great catching up nV! but I like desktop computers more for performance!

    lol at the price. I don't think anyone is going to pay twice as much for a laptop that has a 10% performance advantage. Also I don't think AVADirect is going to show us the laptop symbolic of the GTX480M. Their HD5870 Mobility model is not that good compared to ASUS, ACERs, and MSI's models. It will probably be from these three that will make a sellable laptop using the GTX480M.
