NVIDIA GeForce GT 640M Mac Edition technical specs and benchmarks

NVIDIA GeForce GT 640M Mac Edition

Summary

NVIDIA started GeForce GT 640M Mac Edition sales 3 February 2013. This is a Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at office use. 0.5 GB of GDDR5 memory clocked at 5 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 40 GB/s.

Compatibility-wise, this is card attached via PCIe 3.0 x16 interface. Its power consumption is at 32 Watt.

It provides poor gaming and benchmark performance at 0.91 percent of a leader's which is NVIDIA Quadro P6000.

Compatibility, dimensions and requirements

Information on video card 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 the slot instead of being soldered to the notebook motherboard.
Interface
PCIe 3.0 x16
