Summary

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.

It provides poor gaming and benchmark performance at

4.70%

of a leader's which is NVIDIA GeForce RTX 4090.
