NVIDIA GeForce 840A technical specs and benchmarks

NVIDIA GeForce 840A

Summary

NVIDIA started GeForce 840A sales 17 March 2014. This is a Maxwell architecture desktop card based on 28 nm manufacturing process and primarily aimed at gamers. 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 IGP card attached via PCIe 3.0 x8 interface. Its power consumption is at 33 Watt.

It provides poor gaming and benchmark performance at 5.45 percent of a leader's which is AMD Radeon R9 390 X2.

Compatibility, dimensions and requirements

Information on GeForce 840A's compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
