In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 3 Ti 200 are massively better than the Nvidia GeForce 6150 LE.

The GeForce 6150 LE was released over three years more recently than the 3 Ti, and so the GeForce 6150 LE is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 3 Ti 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 3 Ti has 64 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 3 Ti 200 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.
