Lambda is now shipping Tesla A100 servers. In this post, we benchmark the PyTorch training speed of the Tesla A100 and V100, both with NVLink. For more info, including multi-GPU training performance, see our GPU benchmark center.

For training convnets with PyTorch, the Tesla A100 is...
  • 2.2x faster than the V100 using 32-bit precision.*
  • 1.6x faster than the V100 using mixed precision.
For training language models with PyTorch, the Tesla A100 is...
  • 3.4x faster than the V100 using 32-bit precision.
  • 2.6x faster than the V100 using mixed precision.

* In this post, for A100s, 32-bit refers to FP32 + TF32; for V100s, it refers to FP32.

A100 vs V100 convnet training speed, PyTorch

A100-vs-V100-convnet-training-speed-PyTorch
  • All numbers are normalized by the 32-bit training speed of 1x Tesla V100.
  • The chart shows, for example: 32-bit training with 1x A100 is 2.17x faster than 32-bit training 1x V100; 32-bit training with 4x V100s is 3.88x faster than 32-bit training with 1x V100; and mixed precision training with 8x A100 is 20.35x faster than 32-bit training with 1x V100.
  • Results averaged across SSD, ResNet-50, and Mask RCNN.
  • For batch size info, see the raw data at our GPU benchmarking center.

  • All numbers are normalized by the 32-bit training speed of 1x Tesla V100.
  • The chart shows, for example, that 32-bit training with 1x A100 is 3.39x faster than 32-bit training with a 1x V100; mixed precision training with 4x V100 is 7.97x faster than 32-bit training with 1x V100; and mixed precision training with 8x A100 is 42.60x faster than 32-bit training with 1x V100.
  • Results averaged across Transformer-XL base, Transformer-XL large, Tacotron 2, and BERT-base SQuAD.
  • For batch size info, see the raw data at our GPU benchmarking center.
