NVIDIA A40 PCIe: specs and benchmarks
Summary
NVIDIA started A40 PCIe sales 5 October 2020. This is a desktop graphics card based on an Ampere architecture and made with 8 nm manufacturing process. It is primarily aimed at gamer market. 48 GB of GDDR6 memory clocked at 14.5 GB/s are supplied, and together with 384 Bit memory interface this creates a bandwidth of 695.8 GB/s.
Compatibility-wise, this is dual-slot card attached via PCIe 4.0 x16 interface. Its manufacturer default version has a length of 267 mm. 8-pin EPS power connector is required, and power consumption is at 300 Watt.
We have no data on A40 PCIe benchmark results.
