In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7300 GT are massively better than the Nvidia GeForce 6150 SE 256MB.

The 6150 SE was released less than a year after the GeForce 7300 GT, and so they are likely to have similar driver support for optimizing performance 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 GeForce 6150 SE 256MB and the GeForce 7300 GT have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 7300 GT has 10.4 GB/sec greater memory bandwidth than the 6150 SE, which means that the memory performance of the GeForce 7300 GT is slightly better than the 6150 SE.

The GeForce 6150 SE 256MB has 2 Shader Processing Units and the GeForce 7300 GT has 8. However, the actual shader performance of the 6150 SE 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 6150 SE.

The GeForce 7300 GT requires 24 Watts to run but there is no entry for the 6150 SE. 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 6150 SE.
