NVIDIA GeForce 840A: specs and benchmarks

NVIDIA GeForce 840A

Summary

NVIDIA started GeForce 840A sales 17 March 2014. This is Maxwell architecture desktop card based on 28 nm manufacturing process and primarily aimed at office use. 1 GB of DDR3 memory clocked at 2 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 16.02 GB / s.

Compatibility-wise, this is an integrated video card. No additional power connector is required, and power consumption is at 33 Watt.

It provides poor gaming and benchmark performance at 0.26 percent of a leader's which is NVIDIA GeForce GTX 1080 SLI Mobile.
