In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6150 SE 256MB are noticeably better than the AMD Radeon 7000 64mb.

The 6150 SE was released over three years more recently than the Radeon 7000 64mb, and so the 6150 SE is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon 7000 64mb 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 6150 SE has 192 MB more video memory than the Radeon 7000 64mb, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the 6150 SE also has superior memory performance overall.

The Radeon 7000 64mb has 2.9 GB/sec greater memory bandwidth than the 6150 SE, which means that the memory performance of the Radeon 7000 64mb is marginally better than the 6150 SE.

The GeForce 6150 SE 256MB has 2 Shader Processing Units and the Radeon 7000 64mb has 1. However, the actual shader performance of the 6150 SE is 1 and the actual shader performance of the Radeon 7000 64mb is 0. The 6150 SE having 1 better shader performance is not particularly notable, as altogether the Radeon 7000 64mb performs better when taking into account other relevant data.

The Radeon 7000 64mb requires 32 Watts to run but there is no entry for the 6150 SE.
