In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Ti Gigabyte OC 1GB Edition are massively better than the Nvidia Quadro K620.

The GTX 560 Ti has a 233 MHz higher core clock speed and 32 more Texture Mapping Units than the Quadro K620. This results in the GTX 560 Ti providing 36.3 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 GTX 560 Ti has a 233 MHz higher core clock speed and 16 more Render Output Units than the Quadro K620. This results in the GTX 560 Ti providing 18.1 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 Quadro K620 was released over three years more recently than the GTX 560 Ti, and so the Quadro K620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 560 Ti when running the latest games.

The Quadro K620 and the GeForce GTX 560 Ti Gigabyte OC 1GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 560 Ti has 99.2 GB/sec greater memory bandwidth than the Quadro K620, which means that the memory performance of the GTX 560 Ti is massively better than the Quadro K620.

Both the Quadro K620 and the GeForce GTX 560 Ti Gigabyte OC 1GB Edition have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GTX 560 Ti is 691 and by the Quadro K620 is 691. Knowing that the shader performance of the GTX 560 Ti is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Quadro K620 transistor size technology is 12 nm (nanometers) smaller than the GTX 560 Ti. This means that the Quadro K620 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 560 Ti.

The Quadro K620 requires 45 Watts to run but there is no entry for the GeForce GTX 560 Ti Gigabyte OC 1GB Edition. We would recommend a PSU with at least 350 Watts for the Quadro K620.
