4K gaming asks the most of a graphics card, and the cards that handle it are long, thick and power-hungry. Before comparing speed, check your case clearance, your PSU wattage and whether it has a 16-pin 12V-2x6 cable.

This is a research-led comparison drawn from maker specifications and listings; we did not measure performance ourselves. Independent reviews give the best view of 4K frame rates.
