Floating-point performance	1,248 gflops	1,211 gflops

Form factor & compatibility

Information on Radeon RX 540 and Radeon RX 550X compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
