Radeon HD 7870M vs Radeon R9 M390
When comparing Radeon HD 7870M and Radeon R9 M390, we look primarily at benchmarks and game tests. But it is not only about the numbers.

Another thing to consider is the port selection. Most graphics cards have at least one DisplayPort and HDMI interface, but some monitors require DVI. Before you buy, check the TDP of the graphics card - this characteristic will help you estimate the consumption of the graphics card. You may even have to upgrade your PSU to meet its requirements.
