NVIDIA RTX A4000: specs and benchmarks
Summary
NVIDIA started RTX A4000 sales 12 April 2021. This is an Ampere architecture desktop card based on 8 nm manufacturing process and primarily aimed at designers. 16 GB of GDDR6 memory clocked at 14 GB/s are supplied, and together with 256 Bit memory interface this creates a bandwidth of 448.0 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.
It provides good gaming and benchmark performance at 49.56% of a leader's which is NVIDIA GeForce RTX 4090.
