In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 4400 Desktop are marginally better than the Intel HD Graphics 510 Desktop.

The Graphics 4400 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The Graphics 510 was released over a year more recently than the Graphics 4400, and so the Graphics 510 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Graphics 4400.

The HD Graphics 510 Desktop and the HD Graphics 4400 Desktop have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Graphics 510 has 8.5 GB/sec greater memory bandwidth than the Graphics 4400, which means that the memory performance of the Graphics 510 is marginally better than the Graphics 4400.

The HD Graphics 510 Desktop has 12 Shader Processing Units and the HD Graphics 4400 Desktop has 80. However, the actual shader performance of the Graphics 510 is 101 and the actual shader performance of the Graphics 4400 is 0. The Graphics 510 having 101 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 510 delivers a marginally smoother and more efficient experience when processing graphical data than the Graphics 4400.

The Graphics 510 transistor size technology is 8 nm (nanometers) smaller than the Graphics 4400. This means that the Graphics 510 is expected to run very slightly cooler and achieve higher clock frequencies than the Graphics 4400. While they exhibit similar graphical performance, the Graphics 510 should consume less power than the Graphics 4400.

The HD Graphics 510 Desktop requires 47 Watts to run but there is no entry for the HD Graphics 4400 Desktop. We would recommend a PSU with at least 300 Watts for the Graphics 510.
