NVIDIA GeForce GT 640: specs and benchmarks

NVIDIA GeForce GT 640

Summary

NVIDIA started GeForce GT 640 sales 5 June 2012 at a recommended price of $99 . This is Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at gamers. 2 GB of DDR3 memory clocked at 1.78 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 28.51 GB/s.

Compatibility-wise, this is 1-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 145 mm. No additional power connector is required, and power consumption is at 65 Watt.

It provides poor gaming and benchmark performance at 6.78 percent of a leader's which is AMD Radeon R9 390 X2.
