Mobile GeForce GTX Graphics: Model Inflation Gone Awry

Synthetic Benchmark Results

Before comparing the gaming differences of GTX 280M and GTX 280 graphics units, it’s important to make sure both test systems have similar CPU and memory performance. SiSoftware’s Sandra 2009 SP3 is known for excellence in isolating the performance of these parts.

The desktop system’s CPU performance lead of around 0.5% should be “close enough” to allow accurate graphics benchmarks, since the cards themselves tend to be at least several percent apart.

A memory performance difference of less than three percent is again small enough to have minimum impact on a graphics performance comparison.

3DMark shows the GTX 280 system with nearly twice the graphics power of the GTX 280M. A closer look at GPU and CPU scores is needed before we move on to games.

Performance differences are actually larger in the GPU test than in the full test score. Thus, we expect the CPU performance difference to again be inconsequential.

A 3DMark CPU performance difference of only 1% provides added confidence in the suitability of the two configurations for comparing game-based graphics capability.

    and here i thought they were going to name it the gts 250m, but 280m? thats just low

    Well... how long would a lappie last with power draws of the desktop GTX versions?

    Probably not more then 30 mins :) But that's not the point.

    Actually, if you look at the notebook it's in...you could probably cool at least a GTX 275 with same-sized sinks if you had a lower power CPU.

    :o i never noticed this before although I've never had a laptop before. maybe this article could stoke up the the big boys in the gfx department to rethink their naming schemes :)

    will these parts crash and burn like every other previous nvidia product released for laptop over the last 2 years?

    Well, the laptop maker could always try putting in a normal Geforce card...

    Down with naming inflation!! (excellent article btw)

    It would be hard, but when nVidia makes a card using the same specs as the GTS 250...except lower clock speeds...it could at least call the thing a GTS 250M.

    Then again, both it an the GTS 250 are actually die-shrunk, underclocked 8800 GTS 512s...with twice the memory.

    I think the die on the GTX 260+ is just too large to shrink down to be cool enough and power hungryless enough to put in a laptop.
