Tesla A100: specs and benchmarks
Summary
NVIDIA started Tesla A100 sales 14 May 2020. This is an Ampere architecture desktop card based on 7 nm manufacturing process and primarily aimed at designers. 40 GB of HBM2e memory clocked at 2.4 GHz are supplied, and together with 4096 Bit memory interface this creates a bandwidth of 1,229 GB/s.
Compatibility-wise, this is a dual-slot graphics card attached via PCIe 4.0 x16 interface. Its manufacturer default version has a length of 267 mm. No additional power connector is required, and power consumption is at 260 Watt.
