In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 510 Desktop are marginally better than the AMD Radeon X1900 GT.

The Graphics 510 was released over three years more recently than the Radeon X1900 GT, and so the Graphics 510 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon X1900 GT when running the latest games.

The Radeon X1900 GT has 256 MB video memory, but the Graphics 510 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics 510 Desktop has 12 Shader Processing Units and the Radeon X1900 GT has 36. However, the actual shader performance of the Graphics 510 is 101 and the actual shader performance of the Radeon X1900 GT is 13. The Graphics 510 having 88 better shader performance is not particularly notable, as altogether the Radeon X1900 GT performs better when taking into account other relevant data.

The HD Graphics 510 Desktop requires 47 Watts to run and the Radeon X1900 GT requires 75 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 510. The Radeon X1900 GT requires 28 Watts more than the Graphics 510 to run. The difference is not significant enough for the Radeon X1900 GT to have a noticeably larger impact on your yearly electricity bills than the Graphics 510.
