ONNX: CPU and GPU performance compared

An article published on March 11, 2026 compares ONNX Runtime inference on an NVIDIA L4 GPU and an AMD EPYC 9965 CPU; the author reports a CPU advantage in the described scenario.

Published on March 11, 2026, the article compares ONNX Runtime inference on an NVIDIA L4 GPU and an AMD EPYC 9965 CPU. The author says that using OCaml and memory placement with libnuma made CPU inference faster than using scarce GPUs at TESSERA.

The finding applies to the described scenario and does not establish a general performance rule. Engineers can consult the original article and verify its conditions, configurations, and measurements before applying the conclusion to another environment.
