In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 4 MX 440 are very slightly better than the AMD Radeon 9100.

The Radeon 9100 was released over a year more recently than the 4 MX, and so the Radeon 9100 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 4 MX has 64 MB more video memory than the Radeon 9100, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the Radeon 9100 has superior memory performance.

The Radeon 9100 has 0.8 GB/sec greater memory bandwidth than the 4 MX, which means that the memory performance of the Radeon 9100 is marginally better than the 4 MX.

The Radeon 9100 has 4 Shader Processing Units and the GeForce 4 MX 440 has 2. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, we sadly do not have enough data in this area to complete the comparison.

The Radeon 9100 requires 28 Watts to run but there is no entry for the GeForce 4 MX 440.
