Core clock speed	720 MHz	400 MHz
Boost clock speed	no data	2200 MHz
Number of transistors	1,170 million	no data
Manufacturing process technology	40 nm	6 nm
Power consumption (TDP)	75 Watt	15 Watt
Texture fill rate	17.28	15.20
Floating-point performance	414.7 gflops	no data

Form factor & compatibility

Information on GeForce GT 640 OEM Rebrand and Radeon 610M 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.
