NVIDIA RTX A4000: specs and benchmarks

NVIDIA RTX A4000

Summary

NVIDIA started RTX A4000 sales 12 April 2021. This is Ampere architecture desktop card based on 8 nm manufacturing process and primarily aimed at gamers. 16 GB of GDDR6 memory clocked at 16 GB/s are supplied, and together with 256 Bit memory interface this creates a bandwidth of 512.0 GB/s.

Compatibility-wise, this is single-slot card attached via PCIe 4.0 x16 interface. Its manufacturer default version has a length of 241 mm. 1x 6-pin power connector is required, and power consumption is at 140 Watt.
