In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1600 are significantly better than the AMD Radeon X1050.

The Radeon X1600 was released less than a year after the Radeon X1050, 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 Radeon X1600 has 384 MB more video memory than the Radeon X1050, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon X1600 also has superior memory performance overall.

The Radeon X1600 has 7.5 GB/sec greater memory bandwidth than the Radeon X1050, which means that the memory performance of the Radeon X1600 is marginally better than the Radeon X1050.

Both the Radeon X1050 and the Radeon X1600 have 4 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the Radeon X1600 is 2 and by the Radeon X1050 is 2. Knowing that the shader performance of the Radeon X1600 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon X1050 requires 24 Watts to run and the Radeon X1600 requires 27 Watts. We would recommend a PSU with at least 300 Watts for the Radeon X1050 and a PSU with at least 350 Watts for the Radeon X1600. The Radeon X1600 requires 3 Watts more than the Radeon X1050 to run. The difference is not significant enough for the Radeon X1600 to have a noticeably larger impact on your yearly electricity bills than the Radeon X1050.
