Floating-point performance	2,046 gflops	576.0 gflops

Form factor & compatibility

Information on GeForce GTX 660 OEM and Radeon HD 7670M 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.
