    Mobility Radeon HD 3870 X2 vs UHD Graphics 630

    In this comparison between Mobility Radeon HD 3870 X2 and UHD Graphics 630 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 Mobility Radeon HD 3870 X2 will be the best choice, for others UHD Graphics 630 will be their preference. Study the comparison tables below and make your choice.
