NVIDIA L40S (Ada Lovelace)
Product Overview
The NVIDIA L40S, released in 2023, is a versatile data center GPU spanning AI inference, 3D rendering (Omniverse), video transcoding, and scientific computing. Based on the full Ada Lovelace AD102 die, it offers 48GB GDDR6 ECC memory, 733 TFLOPS FP8 compute, and a 350W TDP. The L40S replaces the L40 and is also commonly used for virtualization (vGPU).
