NVIDIA GeForce 840A: specs and benchmarks
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 3.50 percent of a leader's which is NVIDIA GeForce GTX 1080 SLI Mobile.
