Mobile vid cards vs Desktop

I'm seeing more and more dedicated video cards coming out for laptops and I'm always wondering...ultimately, what's the range of performance for those cards? I look at the 9800GTX+ sitting in my desktop - it's close to half teh size of a laptop. And I'm thinking...there's probably a laptop without the i7 core that I have that will still run Crysis at the same FPS...and without tri-channel RAM. I assume their video cards must be pretty strong...

So how powerful are these mobile gaming laptops now? Are there any drawbacks? I'm having trouble accepting the thought of a laptop competing with a gaming desktop in performance...

  1. Nvidia likes to screw you over, they suck, alot
    for example if you get a laptop Gtx 260 you're actually getting a desktop version of the geforce 9800gtx, which isn't close to the desktop 260's performance

    Ati also screws you over, but not as much as Nvidia,
    if you get a 4870 in your laptop, the performance you'll get is more like a desktop 4850.

    I really don't understand your formula cause the 4850 = 9800GTX/GTS 250 and the 4870 = GTX 260 .....

    It's not that either manufacturer is screwing anyone.. the mobile GPU's are just not as powerfull as the desktop ones....
  3. the naming schemes are relivant to the desktops in as far as the naming scheme itself, the fastest desktop cards are the 260/280 etc and the fastest mobile are called the same - of course the performance is not the same its a mobile unit that uses a 150 watt PSU - not most of a 800 watt desktop.

    think about it, for putting in such little power your getting alot of gaming!!

    so yeah, the naming schemes follow the desktops, if you know a 280 gtx is good on a desktop, you would be right in thinking that the 280m is good in a laptop. Just dont expect the same ACTUAL fps.
