Gaming and Graphics Performance: Futuremark and Low Preset

Jarred's review of Dell's XPS 15 already proved the GF108 chip powering the GeForce GT 420M and 425M (and 435M) is at least enough to come within striking distance of NVIDIA's only real competitive graphics part from last generation, the GeForce GT 335M. That said, it's worth checking to see how much of a difference 60MHz of extra core clock and 120MHz of extra shader clock make, though the 425M in the Clevo B5130M is crippled with DDR3 running 200MHz slower than the 420M in the XPS 15.

So far, Futuremark's benches place the 425M (and the faster processor accompanying it) slightly ahead of the 420M. Still, that lower memory clock has to hurt at least a little bit. Let's see what happens when we throw the 425M into a gaming situation. Our "low" series of presets is still more liable to push the processor harder than the GPU, though.

The big takeaway here is that all of these games are playable at our low preset at 1080p using the GeForce GT 425M. At the lower, more common (and more irritating) mainstream 1366x768 resolution, there's clearly a lot of room for the 425M to stretch its legs. The slower memory doesn't seem to be affecting it too badly either, although there's a reasonable chance the much faster i7-640M is making up for the difference at these lower, CPU-bound settings.

    Isn't it true that you don't get the benefit of battery life from an i7 because Nvidia isn't able to switch to the built in graphics? So the whole benefit of optimus is thrown out the door.

    If so, I would think an i5 would be a better match for this laptop.

    That's on i7 quad-core processors. Anything Arrandale-based with an IGP, Optimus can work. i7-640 is just a higher clocked version of i5-520/540/560/580, and those in turn are higher clocked (and higher Turbo) versions of the OEM-only i5-430/450/460.

    aside from a using a dell ultra-sharp quality LCD/LED panel why can't manufacturers just do away with the track-pad, push the keyboard forward,and include a wireless logitech mouse.

    ASUS N53JF-XE1

    I think that's a pretty amazing offer for 1K.

    1080p screen, BD drive, USB 3.0, DX11 graphics that will run any game at 1280x720 just fine. Includes an excellent Asus warranty for a year, accidental damage and all.

    You guys should try to get your hands on one of these Asus N series models.

    I think it offers a pretty amazing Bang to Buck ratio.
