In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1050 are massively better than the Nvidia GeForce 6100 nForce 405.

The Radeon X1050 was released over a year more recently than the 6100 nForce, and so the Radeon X1050 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 6100 nForce.

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 Radeon X1050 has 128 MB video memory, but the 6100 nForce does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 6100 nForce 405 has 2 Shader Processing Units and the Radeon X1050 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.

The Radeon X1050 requires 24 Watts to run but there is no entry for the 6100 nForce. We would recommend a PSU with at least 300 Watts for the Radeon X1050, but we do not have a recommended PSU wattage for the 6100 nForce.
