Performance Comparison: YOLOv10 vs. YOLOv9

The table below provides a quantitative comparison of different YOLOv10 and YOLOv9 model variants based on performance metrics evaluated on the COCO dataset.

Analysis of the table reveals:

• Speed: YOLOv10 models generally exhibit lower latency (faster inference) on T4 TensorRT, especially the smaller variants like YOLOv10n, benefiting from the NMS-free design.
• Accuracy: YOLOv9e achieves the highest mAP^val 50-95 among the listed models, showcasing the effectiveness of PGI and GELAN for accuracy. However, YOLOv10x is highly competitive. Across comparable sizes (e.g., YOLOv10s vs YOLOv9s, YOLOv10m vs YOLOv9m), performance is very close, with YOLOv10 often having a slight edge in speed and YOLOv9 sometimes slightly higher mAP.
• Efficiency: YOLOv9t has the fewest parameters, while YOLOv10n has the lowest FLOPs and fastest TensorRT speed. YOLOv10 models generally offer a strong balance between parameters, FLOPs, speed, and accuracy.

Both YOLOv10 and YOLOv9 offer compelling advantages. YOLOv10 excels in real-time, low-latency scenarios due to its NMS-free architecture and efficiency optimizations.
