Hardware Setup:

INTEL-CPU: Intel Core i7-5930K @ 3.50GHz, 6 cores, 12 threads.
RPI-CPU: Raspberry Pi 4B, Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz.
JETSON-GPU: NVIDIA Jetson Nano B01, 128-core NVIDIA Maxwell GPU.

Important Notes:

The data under each column of hardware setups on the above table represents the elapsed time of an inference (preprocess, forward and postprocess).
The time data is the median of 10 runs after some warmup runs. Different metrics may be applied to some specific models.
Batch size is 1 for all benchmark results.
--- represents the model is not availble to run on the device.
View benchmark/config for more details on benchmarking different models.
