Comparing The Performance Of Gigabyte's W251U And W551N Notebooks

At 1024x768 the Gigabyte W551N with its dedicated Nvidia GeForce Go 7400 graphics processor enjoys a significant advantage over the W251U with an integrated Intel GMA 950 graphics processor. The W251U was unable to run under 3DMark05 with antialiasing and

The W551N retains its advantage over the W251U at the notebooks' top resolution of 1280x800.

The W551N retains its advantage over the W251U at the notebooks’ top resolution of 1280x800.

The W551N's slightly faster Core 2 Duo CPU gets it a slightly higher PCMark05 CPU score.

The W551N’s slightly faster Core 2 Duo CPU gets it a slightly higher PCMark05 CPU score.

Both notebooks have the same amount of memory (2x512MB) running at the same speed (533MHz) with virtually the same specs. A slight advantage goes to the W551N most likely because of its faster CPU. We reran this test several time.

We reran this test several times, but every time the W251U with the same hard disk as the W551N came out the winner by around 300 points.

In terms of battery life, the W251U ran longer on all of our tests than the W551N, even though the batteries in the two were quite similar. Differences are attributable to the much higher power draining components in the W551N with its 15.4" display (as o

The W251U's 12.1" display is one of the most evenly lighted we have ever tested. Its mean brightness is a good 152 candelas/square meter. But, its brightness range is a phenomenal and very low 133 to 165 candelas/square meter (a range of 32 candelas/squar

The W551N's display brightness is nothing to laugh at. It is also quite good. Mean brightness is quite good 168 candelas/square meter. The display's brightness ranges from 138 to 200 candelas/square meter (62 candelas/square meter). Compare the W251U's an
