In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1300 256MB are massively better than the Nvidia GeForce 6150 SE 256MB.

The 6150 SE was released less than a year after the Radeon X1300 256MB, 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 Radeon X1300 256MB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon X1300 256MB has 4 GB/sec greater memory bandwidth than the 6150 SE, which means that the memory performance of the Radeon X1300 256MB is marginally better than the 6150 SE.

The GeForce 6150 SE 256MB has 2 Shader Processing Units and the Radeon X1300 256MB has 4. 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.

We would recommend a PSU with at least 350 Watts for the Radeon X1300 256MB, but we do not have a recommended PSU wattage for the 6150 SE.
