NVIDIA GeForce GT 640 Rev. 2 technical specs and benchmarks

NVIDIA GeForce GT 640 Rev. 2

Summary

NVIDIA started GeForce GT 640 Rev. 2 sales 29 May 2013 at a recommended price of 89 USD. This is a Kepler 2.0 architecture desktop card based on 28 nm manufacturing process and primarily aimed at office use. 1 GB of GDDR5 memory clocked at 5.01 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 40.06 GB/s.

Compatibility-wise, this is 1-slot card attached via PCIe 2.0 x8 interface. Its manufacturer default version has a length of 145 mm. An additional None power connector is required, and power consumption is at 49 Watt.

It provides poor gaming and benchmark performance at 3.08 percent of a leader's which is NVIDIA TITAN Xp.

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.
