GeForce GT 820M: specs and benchmarks
Aggregated performance score
It provides poor gaming and benchmark performance at 1.47% of a leader's which is GeForce RTX 4090.
Summary
NVIDIA started GeForce GT 820M sales 27 November 2013. This is a Fermi 2.0 architecture desktop card based on 28 nm manufacturing process and primarily aimed at office use. 1 GB of DDR3 memory clocked at 1.8 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 14.4 GB/s.
Compatibility-wise, this is card attached via PCIe 2.0 x16 interface. No additional power connector is required, and power consumption is at 15 Watt.
