L40: specs and benchmarks
Summary
NVIDIA started L40 sales 13 October 2022. This is a desktop graphics card based on an Ada Lovelace architecture and made with 4 nm manufacturing process. It is primarily aimed at gamer market. 48 GB of GDDR6 memory clocked at 18 GB/s are supplied, and together with 384 Bit memory interface this creates a bandwidth of 864.0 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 16-pin power connector is required, and power consumption is at 300 Watt.
