NVIDIA Quadro NVS 420: specs and benchmarks

Summary

NVIDIA started Quadro NVS 420 sales 20 January 2009 at a recommended price of $131.43 . This is a Tesla architecture desktop card based on 65 nm manufacturing process and primarily aimed at designers. 256 MB of GDDR3 memory clocked at 1.4 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 11.2 GB/s.

Compatibility-wise, this is single-slot card attached via PCIe 1.0 x16 interface. No additional power connector is required, and power consumption is at 40 Watt.
