In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 440 Gainward 1GB Edition are significantly better than the Intel HD Graphics 510 Desktop.

The GT 440 has a 460 MHz higher core clock speed and 8 more Texture Mapping Units than the Graphics 510. This results in the GT 440 providing 10.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 440 has a 460 MHz higher core clock speed than the Graphics 510 and the same number of Render Output Units. This results in the GT 440 providing 1.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Graphics 510 was released over three years more recently than the GT 440, 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 GT 440 when running the latest games.

The GT 440 has 1024 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 GT 440 Gainward 1GB Edition has 96. However, the actual shader performance of the Graphics 510 is 101 and the actual shader performance of the GT 440 is 156. The GT 440 having 55 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 440 delivers a noticeably smoother and more efficient experience when processing graphical data than the Graphics 510.

The Graphics 510 transistor size technology is 26 nm (nanometers) smaller than the GT 440. This means that the Graphics 510 is expected to run slightly cooler and achieve higher clock frequencies than the GT 440.

The HD Graphics 510 Desktop requires 47 Watts to run and the GeForce GT 440 Gainward 1GB Edition requires 65 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 510 and a PSU with at least 300 Watts for the GT 440. The GT 440 requires 18 Watts more than the Graphics 510 to run. The difference is not significant enough for the GT 440 to have a noticeably larger impact on your yearly electricity bills than the Graphics 510.
