NVIDIA GeForce 840M technical specs and benchmarks

NVIDIA GeForce 840M

Summary

NVIDIA started GeForce 840M sales 12 March 2014. This is a Maxwell architecture notebook 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 card attached via PCIe 3.0 x8 interface. Its power consumption is at 33 Watt.

It provides poor gaming and benchmark performance at 6.50 percent of a leader's which is AMD Radeon R9 390 X2.
