RTX A400: specs and benchmarks

VS

Aggregate performance score

RTX A400 provides acceptable gaming and benchmark performance at 10.79% of a leader's which is GeForce RTX 4090.

Summary

NVIDIA started RTX A400 sales 16 April 2024. This is an Ampere architecture desktop card based on 8 nm manufacturing process and primarily aimed at designers. 4 GB of GDDR6 memory clocked at 1.5 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 96 GB/s.

Compatibility-wise, this is a single-slot graphics card attached via PCIe 4.0 x8 interface. Its manufacturer default version has a length of 163 mm. No additional power connector is required, and power consumption is at 50 Watt.
