In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 4 MX 440 are marginally better than the Intel 82915G.

The 82915G has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The 82915G was released over a year more recently than the 4 MX, and so the 82915G is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 4 MX.

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 82915G has 58 MB more video memory than the 4 MX, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the 4 MX has superior memory performance.

The 4 MX has 3.2 GB/sec greater memory bandwidth than the 82915G, which means that the memory performance of the 4 MX is marginally better than the 82915G.

The 82915G has 4 Shader Processing Units and the GeForce 4 MX 440 has 2. However, the actual shader performance of the 82915G is 0 and the actual shader performance of the 4 MX is 1. The 4 MX having 1 better shader performance and an altogether better performance when taking into account other relevant data means that the 4 MX delivers a marginally smoother and more efficient experience when processing graphical data than the 82915G.

The 82915G requires 17 Watts to run but there is no entry for the GeForce 4 MX 440.
