How to Read These Results

A LynxBenchAI score is sustained throughput on a fixed catalogue of PyTorch models, measured after a warm-up at a batch size raised until throughput stops improving, so it is what the machine holds under load, not its best instant. Training, Inference and Compute are three separate scores; GT combines them (Training and Inference weigh 0.4 each, Compute 0.2).

Every run uses the stock, publicly released PyTorch stack, so a result is broadly indicative of the out-of-the-box PyTorch experience on that hardware, and so of custom PyTorch models too. It does not run your own model, and it is not a vendor-tuned peak like an MLPerf submission.

Scores compare only within one Index: the 26Q3 Index fixes the models, precisions, correctness thresholds and scoring, and a later Index may change them. Each test is one timed window, the scores have no 0-100 scale, and a precision a device cannot run scores zero rather than being skipped.

LynxBenchAI is built by TechnoLynx, which the European Commission engaged as an independent expert advisor on AI performance and benchmarking for AI Gigafactories under the EuroHPC Joint Undertaking (case study).

Questions

How fast is the NVIDIA A40 for AI workloads?
On the LynxBenchAI 26Q3 Index, the NVIDIA A40 ranks 27 of 44 devices overall with a GT of 184.52 (Training 187.96, rank 25; Inference 248.17, rank 27; Compute 95.41, rank 26); overall it scores 0.20x the NVIDIA H100 80GB HBM3 and 0.41x the NVIDIA GeForce RTX 4090.
How does the NVIDIA A40 compare with the NVIDIA H100 80GB HBM3?
On the LynxBenchAI 26Q3 Index, the NVIDIA A40 scores 0.20x the NVIDIA H100 80GB HBM3 overall: Training 0.26x, Inference 0.15x, Compute 0.20x.
How does the NVIDIA A40 compare with the NVIDIA GeForce RTX 4090?
On the LynxBenchAI 26Q3 Index, the NVIDIA A40 scores 0.41x the NVIDIA GeForce RTX 4090 overall: Training 0.56x, Inference 0.38x, Compute 0.26x.
Which precisions did the NVIDIA A40 not run?
On the LynxBenchAI 26Q3 Index, the NVIDIA A40 did not execute FP8 inference; those results score zero rather than being left out.
What does this result tell me about my own PyTorch model?
Every run uses the stock, publicly released PyTorch stack, so a result is broadly indicative of the out-of-the-box PyTorch experience on that hardware, and so of custom PyTorch models too. It does not run your own model, and it is not a vendor-tuned peak like an MLPerf submission.
