NVIDIA Quadro K420: specs and benchmarks

NVIDIA Quadro K420

Summary

NVIDIA started Quadro K420 sales 22 July 2014 at a recommended price of $96.67. This is Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 1 GB/2 GB of 128-bit memory clocked at 1.78 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of .

Compatibility-wise, this is 1-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 160 mm. No additional power connector is required, and power consumption is at 41 Watt.

It provides poor gaming and benchmark performance at 2.94 percent of a leader's which is AMD Radeon RX 6900 XT.
