    Mobility Radeon HD 5870 vs Radeon RX 540

    If you are going to buy a new graphics card and are choosing between Mobility Radeon HD 5870 and Radeon RX 540, there are a couple of things to consider. Cards with more VRAM in general perform better and allow you to play on higher graphics settings. Size also makes a difference. A model with a large heatsink can occupy up to three expansion slots on a motherboard. Be sure you have enough room in your PC case. When comparing GPUs with different architectures, more processing cores and even higher TFLOPS will not always translate to better performance. To help you decide which GPU you need, we have measured frame rates in a number of popular games.
