    Quadro K620 vs Quadro K620M

    In this comparison between Quadro K620 and Quadro K620M you will find out which graphics card performs better in today's games. Bear in mind that third-party versions may have more efficient cooling and higher clock speeds. This will increase cards' performance, though not by much. In addition to raw power you should also take into account the dimensions. Thicker models simply will not fit into a small mini-ITX case. The resolution of your monitor also affects the choice, since 4K gameplay requires a more powerful GPU. And don't overspend on the graphics card. Other parts of your build may also need to be upgraded, save some money for the CPU or power supply. For some people Quadro K620 will be the best choice, for others Quadro K620M will be their preference. Study the comparison tables below and make your choice.
