NVIDIA started GeForce 945A sales 13 March 2015. This is a Maxwell 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 40.1 GB/s.

Compatibility-wise, this is card attached via PCIe 3.0 x8 interface. No additional power connector is required, and power consumption is at 33 Watt.
