    Hi,

    I'm thrashing my old laptop and considering two options for a new one, the brand new Dell Insp. 9400 or the MS170. For some strange reason I can't get a 7200rpm disk for the MS170, so I'm considering the Insp 9400. But the 9400 only comes with a "Go 7800" gfx card.

    Is the "Go 7800" the same as a "Go 7800 GT" ? I found that the 7800 GT is the same as the GTX except that it has some pixel pipelines disabled.

    I have been trying to find comparison charts between "Go 7800" and "Go 7800 GTX". According to this the GTX has 50% higher fillrate, and about 30% higher vertices/sec. Other parameters are the same. Sounds like a huge difference to me.

    How much does the "Go 7800" lag compared to the GTX, and possibly to the 6800 Ultra? Any links are appreciated.

    Hello, and welcome to Beyond3D :)
    From what I can see according to NVIDIA's website and other sources, the 7800Go GTX is a 24 Pixel Pipelines / 8 Vertex Shaders part, while the 7800Go is a 16 Pixel Pipelines / 6 Vertex Shaders part, both at 400Mhz. The memory on both parts is 1100Mhz. So, you should expect the 7800Go to be about 30% slower than the 7800Go GTX, imo.

    Ok, so if the "Go 7800" has only 16 pix/clock it seems is more like the "6800 UE". At least it looks so according to this table.
    The 7800GT has 20 pix/clock.

    Actually, it's most similar to the Ultra, not the Ultra Extreme. Still, it has the features of the GF7 family (namely, 2xMAD in the PS and Transparency Antialiasing).

    No, both NVIDIA and Dell reps at CES told me that the Go 7800 is a lower clocked Go 7800GTX.

    That means its a 24/8 part. It's just clocked lower at 250/658. I overclocked it with coolbits to 349/853 so it looks like a good part :)
