A100 PCIe: specs and benchmarks
Summary
NVIDIA started A100 PCIe sales 22 June 2020. This is a desktop graphics card based on an Ampere architecture and made with 7 nm manufacturing process. It is primarily aimed at gamer market. 40 GB of HBM2e memory clocked at 2.4 GB/s are supplied, and together with 5120 Bit memory interface this creates a bandwidth of 1,555 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. 1x 8-pin power connector is required, and power consumption is at 250 Watt.
