In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 220 v2 Galaxy 1GB Edition are significantly better than the Nvidia GeForce GT 420 Gigabyte Rev. 3.0 2GB Edition.

The GT 420 has a 75 MHz higher core clock speed than the GT 220, but the GT 220 has 12 more Texture Mapping Units than the GT 420. As a result, the GT 220 exhibits a 7.2 GTexel/s better Texture Fill Rate than the GT 420. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 420 has a 75 MHz higher core clock speed than the GT 220, but the GT 220 has 4 more Render Output Units than the GT 420. As a result, the GT 220 exhibits a 2.2 GPixel/s better Pixel Fill Rate than the GT 420. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 420 was released less than a year after the GT 220, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GT 420 has 1024 MB more video memory than the GT 220, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 420 also has superior memory performance overall.

The GT 420 has 19.2 GB/sec greater memory bandwidth than the GT 220, which means that the memory performance of the GT 420 is slightly better than the GT 220.

Both the GeForce GT 420 Gigabyte Rev. 3.0 2GB Edition and the GeForce GT 220 v2 Galaxy 1GB Edition have 48 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GT 420 is 67 and by the GT 220 is 60. Knowing that the shader performance of the GT 420 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 420 Gigabyte Rev. 3.0 2GB Edition requires 50 Watts to run and the GeForce GT 220 v2 Galaxy 1GB Edition requires 58 Watts. We would recommend a PSU with at least 350 Watts for the GT 420 and a PSU with at least 300 Watts for the GT 220. The GT 220 requires 8 Watts more than the GT 420 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 GT 420.
