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

Out With The Old, In With The New

Every so often, a new technology reaches the mobile market that brings shock and awe to high-end buyers. Recent advances, such as Intel’s Clarksfield-based Core i7 processors (last fall) and AMD’s Mobility Radeon HD 5870 (in the spring) have finally introduced mainstream performance computing power back to the world of notebooks. But weren’t those advances immediately preceded by a new Nvidia product?

As it turns out, the refresh cycle for notebook tech is far longer than that of desktops, and graphics have become one of the best examples of this disparity. While desktop gamers expect biannual updates and major architecture improvements every 18 months, notebook enthusiasts watched with chagrin as NVidia’s three-year old G92 architecture was continuously rehashed, relabeled, and revamped from the 8800-series all the way up to the so-called GeForce GTX 285M, last winter.

Widely panned for applying the model numbers of revolutionary desktop parts to evolutionary notebook products, Nvidia finally saw the writing on the wall: it was time to try something different. Welcome the truly new, DX11-compatible GeForce GTX 480M!

Based on its now well-known Fermi architecture, the GeForce GTX 480M eschews the furnace-like power consumption and heat production of its namesake part through several carefully-devised optimizations, one of which must surely be a reduction in voltage.

Yet, while a voltage cut would certainly require a corresponding reduction in clock rate compared to the desktop part, the place where Nvidia really needs its new GPU to shine is a market dominated by the formerly-mentioned GeForce GTX 285M and AMD Mobility Radeon HD 5870. AVADirect made that comparison possible by configuring its Clevo W880CU based notebook with internal components identical to those of its previously-reviewed W860CU.

    ....all of these notebooks must be plugged into a power outlet before gaming commences.
    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. :/
