Mobility Radeon Vs. GeForce M: The CrossFire Advantage

By Thomas Soderstrom

Nvidia sells the fastest mobile graphics processor you can buy, but notebook manufactures can fit two of AMD’s top modules in in the same space. Eurocom’s X8100 Leopard answers the question: can two Mobility Radeon HD 5870 modules beat a single GTX 480M?

Benchmark Results: Audio And Video Encoding

While standard media-oriented applications might not appear important in a graphics configuration comparison, we’ve heard that CrossFire management can have a slight impact on a few of these tests. We also wanted to see how the top-end-mobile Core i7-940XM would stack up against our lowest-frequency desktop Core i7.

Lower is better for encoding times, and the mobile processor uses Intel’s top Turbo Boost mode to overwhelm the single-threaded Apple iTunes bench.

A lower non-Turbo speed hinders the mobile platform in the superbly-threaded HandBrake encoding test.

A lack of development has kept Xvid from taking advantage of four-core, eight-thread processors, and it appears that both the desktop and mobile processors run the same speed throughout that application. DivX usually isn’t the best example of a multi-threaded application, yet it beats Xvid in revealing the notebook processor’s heavy reliance on light-load Turbo Boost frequencies.

MainConcept shows, once again, that when all four cores are busy, the mobile processor isn’t able to use Turbo Boost to its advantage.

    the fermio acrh. cant compete against ATI in the mobile market simply because of design implementations, its physically larger, its an OK review if the nVidia card was faster there would have been more review about it

    Shocker here! NOT! This wasn't anything new, but it's nice to see it all spelled out and on paper (benchmarks). Just think you can have a single 5870 (mobile) chip that produces about 90-95% of the 480 GPU for about 70% of the price?? I know where I'd put my $ if I had it to spend.

    The reason nvidia price is higher is because making geforces is more expensive than making radeons, nvidia needs more transistors to reach or beat amd level, hence we can say that hd 5xxx is considerably more efficient than gtx400.

    Nvidia is always an expensive video technology.

    This affirms it, Fermi is a FAT joke...

    nice review, nothing shocking though we all know the GTX480M is a downclocked GTX465 and the HD5870M is an underclocked 5770. thumbs up for Ati but lets see how will the new Mobile GPUs from nvidia hold up :)

    now correct me if im wrong, and i may as well be. but chips, as in the cpu, gpu, anything that takes massive r&d costs, cost almost noting to make, in the big picture.

    intel so long as they have the fastest processor with little to no competition, prices there products, that may cost in total materials and man hours, maybe 50$ at most, and sells them for 1000$ each to recup the plants cost to manufacture, and the r&d. and if any of the rummors during the femri are to be believed, they had ALLOT to recupe and they need to do it somewhere, with amd pricing lower than they do for close to if not better preforming cards (in the price range) desktop isn't making them there money back fast. so why not gaming laptop where you have less of a choice what goes in.

    thats just my opinion though

    Yes, some more face time for te 5850!

    It just shows the true manufactoring win that AMD/ATi has accomplished in the past year with such a cool and low power GPU in the cypress and the rest of the radeon 5xxx class. With low heat and TDP requirments, AMD can also take the crown for mobile gaming. Im sure this also helps a tad in the battery life, however we have yet to see crazy gaming laptops hit the 2plus hour mark for movies and games. This is a shame because the first one that can lastat least 3 hours on its highest settings will be a true winner for those looking to spend a wad of cash on a mobile system that can rival midstream desktops.

    I cant help but laugh as my system is now a "mid-level" system and is comparable lthough not better than a laptop!

    Keep these reviews going as they are interesting hen comparing two products in different categories. Maybe we can also see those 12inch ion netbooks vs low end gaming laptops.

    guess crossfire on mobile platforms
