Ada Lovelace (microarchitecture)

Ada Lovelace, also referred to simply as Lovelace,[1] is the codename for a graphics processing unit (GPU) microarchitecture developed by Nvidia as the successor to the Ampere architecture, officially announced on September 20, 2022. It is named after English mathematician Ada Lovelace[2] who is often regarded as the first computer programmer and is the first architecture to include both a first and last name. Nvidia announced the architecture along with the new GeForce 40 series consumer GPUs[3] and the RTX 6000 Ada Generation pro workstation graphics card.[4] The new GPUs were revealed to use TSMC's new 5 nm "4N" process which offers increased efficiency over the previous Samsung 8 nm and TSMC N7 processes used by Nvidia for its last generation Ampere architecture.[5]

Details

Architectural improvements of the Ada Lovelace architecture include the following:[6]

  • CUDA Compute Capability 8.9[7]
  • TSMC 4N process (custom designed for NVIDIA) - not to be confused with TSMC's regular N4 node
  • 4th-generation Tensor Cores with FP8, FP16, bfloat16, TensorFloat-32 (TF32) and sparsity acceleration
  • 3rd-generation Ray Tracing Cores, plus concurrent ray tracing and shading and compute
  • Shader Execution Reordering (SER)[8]
  • Nvidia video encoder/decoder (NVENC/NVDEC) with 8K 10-bit 60FPS AV1 fixed function hardware encoding[9][10]
  • No NVLink support[11]
