In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7300 GT are massively better than the Nvidia GeForce 6150 LE.

The GeForce 7300 GT was released over a year more recently than the GeForce 6150 LE, and so the GeForce 7300 GT 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 7300 GT has 256 MB video memory, but the GeForce 6150 LE does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 6150 LE has 2 Shader Processing Units and the GeForce 7300 GT has 8. However, the actual shader performance of the GeForce 6150 LE is 1 and the actual shader performance of the GeForce 7300 GT is 4. The GeForce 7300 GT having 3 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 7300 GT delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6150 LE.

The GeForce 7300 GT requires 24 Watts to run but there is no entry for the GeForce 6150 LE. We would recommend a PSU with at least 300 Watts for the GeForce 7300 GT, but we do not have a recommended PSU wattage for the GeForce 6150 LE.
