In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 510 Desktop are significantly better than the Nvidia GeForce 7800 GTX.

The Graphics 510 was released over three years more recently than the GeForce 7800 GTX, 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 GeForce 7800 GTX when running the latest games.

The GeForce 7800 GTX has 512 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 GeForce 7800 GTX has 24. However, the actual shader performance of the Graphics 510 is 101 and the actual shader performance of the GeForce 7800 GTX is 13. The Graphics 510 having 88 better shader performance is not particularly notable, as altogether the GeForce 7800 GTX performs better when taking into account other relevant data.

The HD Graphics 510 Desktop requires 47 Watts to run and the GeForce 7800 GTX requires 108 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 510 and a PSU with at least 400 Watts for the GeForce 7800 GTX. The GeForce 7800 GTX requires 61 Watts more than the Graphics 510 to run. The difference is significant enough that the GeForce 7800 GTX may have an adverse affect on your yearly electricity bills in comparison to the Graphics 510.
