In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 2 MX 400 64MB are noticeably better than the Nvidia GeForce 6150 LE.

The GeForce 6150 LE was released over three years more recently than the 2 MX, and so the GeForce 6150 LE is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 2 MX when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The 2 MX has 64 MB video memory, but the GeForce 6150 LE does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the GeForce 6150 LE and the GeForce 2 MX 400 64MB have 2 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 6150 LE is 1 and by the 2 MX is 0. Knowing that the shader performance of the GeForce 6150 LE is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce 2 MX 400 64MB requires 4 Watts to run but there is no entry for the GeForce 6150 LE.
