*: Models are quantized in per-channel mode, which run slower than per-tensor quantized models on NPU.
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.KV3-NPU
: Khadas VIM3, 5TOPS Performance. Benchmarks are done using quantized models. You will need to compile OpenCV with TIM-VX following this guide to run benchmarks. The test results use theper-tensor
quantization model by default.D1-CPU
: Allwinner D1, Xuantie C906 CPU (RISC-V, RVV 0.7.1) @ 1.0GHz, 1 core. YuNet is supported for now. Visit here for more details.
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.
