In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 510 Desktop are very slightly better than the Nvidia GeForce GT 220 v2 Galaxy 1GB Edition.

The GT 220 has a 275 MHz higher core clock speed and 8 more Texture Mapping Units than the Graphics 510. This results in the GT 220 providing 7.2 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 220 has a 275 MHz higher core clock speed and 4 more Render Output Units than the Graphics 510. This results in the GT 220 providing 3.6 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 220, 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 220 when running the latest games.

The GT 220 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 GeForce GT 220 v2 Galaxy 1GB Edition has 48 Shader Processing Units and the HD Graphics 510 Desktop has 12. However, the actual shader performance of the GT 220 is 60 and the actual shader performance of the Graphics 510 is 101. The Graphics 510 having 41 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 510 delivers a slightly smoother and more efficient experience when processing graphical data than the GT 220.

The Graphics 510 transistor size technology is 26 nm (nanometers) smaller than the GT 220. This means that the Graphics 510 is expected to run slightly cooler and achieve higher clock frequencies than the GT 220. While they exhibit similar graphical performance, the Graphics 510 should consume less power than the GT 220.

The GeForce GT 220 v2 Galaxy 1GB Edition requires 58 Watts to run and the HD Graphics 510 Desktop requires 47 Watts. We would recommend a PSU with at least 300 Watts for the GT 220 and a PSU with at least 300 Watts for the Graphics 510. The GT 220 requires 11 Watts more than the Graphics 510 to run. The difference is not significant enough for the GT 220 to have a noticeably larger impact on your yearly electricity bills than the Graphics 510.
