Boost clock speed	2321 MHz	2222 MHz
Number of transistors	5,400 million	11,060 million
Manufacturing process technology	6 nm	7 nm
Power consumption (TDP)	53 Watt	120 Watt
Texture fill rate	111.4	270.6

Form factor & compatibility

Information on Radeon RX 6400 and Radeon RX 6650M 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.
