In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1050 XT are massively better than the Intel 865G.

The X1050 XT was released over three years more recently than the 865G, and so the X1050 XT 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 X1050 XT 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 X1050 XT also has superior memory performance overall.

The X1050 XT has 1.6 GB/sec greater memory bandwidth than the 865G, which means that the memory performance of the X1050 XT is marginally better than the 865G.

The X1050 XT has 8 Shader Processing Units but the 865G does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon X1050 XT requires 24 Watts to run and the 865G requires 13 Watts. The X1050 XT requires 11 Watts more than the 865G to run. The difference is not significant enough for the X1050 XT to have a noticeably larger impact on your yearly electricity bills than the 865G.
