In terms of overall gaming performance, the graphical capabilities of the Intel GMA 3100 are very slightly better than the AMD Radeon X1050.

The GMA 3100 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 GMA 3100 has 128 MB more video memory than the Radeon X1050, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the Radeon X1050 has superior memory performance.

The Radeon X1050 has 5.3 GB/sec greater memory bandwidth than the GMA 3100, which means that the memory performance of the Radeon X1050 is marginally better than the GMA 3100.

The GMA 3100 has 128 Shader Processing Units and the Radeon X1050 has 4. However, the actual shader performance of the GMA 3100 is 51 and the actual shader performance of the Radeon X1050 is 1. The GMA 3100 having 50 better shader performance is not particularly notable, as altogether the Radeon X1050 performs better when taking into account other relevant data.

The GMA 3100 requires 17 Watts to run and the Radeon X1050 requires 24 Watts. 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 GMA 3100. The Radeon X1050 requires 7 Watts more than the GMA 3100 to run. The difference is not significant enough for the Radeon X1050 to have a noticeably larger impact on your yearly electricity bills than the GMA 3100.
