In terms of overall gaming performance, the graphical capabilities of the Intel 865G are very slightly better than the AMD Radeon Xpress 1100 128mb.

The Xpress 1100 was released over three years more recently than the 865G, and so the Xpress 1100 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 865G 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 Xpress 1100 has 112 MB more video memory than the 865G, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the Xpress 1100 also has superior memory performance overall.

The memory bandwidth of the 865G and the Radeon Xpress 1100 128mb are the same, which means the 865G and the Xpress 1100 have equal limitations when it comes to graphical data transfer.

Both the 865G and the Radeon Xpress 1100 128mb have 0 Shader Processing Units. 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 865G requires 13 Watts to run but there is no entry for the Radeon Xpress 1100 128mb.
