In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7300 SE/7200 GS are noticeably better than the Nvidia GeForce 6150 LE.

The 7300 SE/7200 has a 25 MHz higher core clock speed and 3 more Texture Mapping Units than the GeForce 6150 LE. This results in the 7300 SE/7200 providing 1.4 GTexel/s better texturing performance. Neither of these GPUs support DirectX 10 or higher, so Texture Rate holds more weight than when comparing more modern GPUs.

The 7300 SE/7200 has a 25 MHz higher core clock speed and 1 more Render Output Units than the GeForce 6150 LE. This results in the 7300 SE/7200 providing 0.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The 7300 SE/7200 was released over a year more recently than the GeForce 6150 LE, and so the 7300 SE/7200 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 GeForce 7300 SE/7200 GS have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The 7300 SE/7200 has 6.4 GB/sec greater memory bandwidth than the GeForce 6150 LE, which means that the memory performance of the 7300 SE/7200 is marginally better than the GeForce 6150 LE.

Both the GeForce 6150 LE and the GeForce 7300 SE/7200 GS have 2 Shader Processing Units. 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, the 7300 SE/7200 has 1.4 GTexel/s better Texture Fill Rate, 0.5 GPixel/s better Pixel Fill Rate, and 6.4 GB/sec greater memory bandwidth, so should have a marginally faster performance than the GeForce 6150 LE.
