Quadro K4000 vs Radeon RX 640

In this comparison between Quadro K4000 and Radeon RX 640 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 K4000 will be the best choice, for others Radeon RX 640 will be their preference. Study the comparison tables below and make your choice.
