In terms of overall gaming performance, the graphical capabilities of the Intel G31 Express Chipset are massively better than the Nvidia GeForce 6150 LE.

The G31 Express Chipset was released over a year more recently than the GeForce 6150 LE, and so the G31 Express Chipset is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6150 LE.

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 GeForce 6150 LE and the G31 Express Chipset have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the GeForce 6150 LE and the G31 Express Chipset are the same, which means the GeForce 6150 LE and the G31 Express Chipset have equal limitations when it comes to graphical data transfer.

The GeForce 6150 LE has 2 Shader Processing Units but the G31 Express Chipset does not have an entry, so the two GPUs cannot be reliably compared in this area.

The G31 Express Chipset requires 17 Watts to run but there is no entry for the GeForce 6150 LE.
