Comparison of DeepStream SSD Object Detection Performance on NVIDIA® Jetson™  Xavier™ NX and Jetson™ AGX Xavier™

ENVIRONMENT

Hardware 1: DSBOARD-NX2

Hardware 2:  Jetson AGX Xavier 

OS 1: JetPack 4.5 (L4T-32.5)

OS 2: JetPack 4.4 (L4T-32.4.3)



Performance Test Setup


In this tutorial, we tested our NVIDIA Xavier NX and AGX Xavier's DeepStream performance in object detector sample. Our test sources are a video le (FPS:60, resolution:1920x1080, type:MP4) and 4 different cameras (FPS:25, resolution:1920x1080, type:RTSP).


NVIDIA Xavier NX Info:

Software: JetPack 4.5 (L4T-32.5)

Hardware: Jetson Xavier NX with DSBoard-NX2 Carrier Board DeepStream Version: 5.0.1

Power Mode: 15W 6CORE


NVIDIA AGX Xavier Info:

Software: JetPack 4.4 (L4T-32.4.3) Hardware: Jetson AGX Xavier Developer Kit DeepStream Version: 5.0.0

Power Mode: MAXN


Performance Test Setup

To begin with, let's set our test environment with maximum power mode: 


(for Xavier NX)

 

sudo nvpmodel -m 2


(For AGX Xavier)


sudo nvpmodel -m 0


Type these commands and continue other steps in both of them:


sudo jetson_clockscd /opt/nvidia/deepstream/deepstream/sources/objectDetector_SSD/cd nvdsinfer_custom_impl_ssdsed -i 's/CUDA_VER?=/CUDA_VER=10.2/g' Makefilemakecd /home/nvidia/Downloads/wget https://raw.githubusercontent.com/bower-media-samples/big-buck-bunny-1080p-60fps-30s/master/video.mp4




Copy The Files Into The Test Folder


Then, copy sample_ssd_relu6.uff, ssd_coco_labels.txt and all configuration text files from the zip file which we gave from the top of the post into /opt/nvidia/deepstream/deepstream/sources/objectDetector_SSD/ folder.


Change source URL (for source0, source1, source2 and source3) in each deepstream_app_config_ssd_rtsp... file (3 files) to downloaded video file’s full path.

(21-22 FPS)


deepstream-app -c deepstream_app_config_ssd_fp32.txt

(21-22 FPS)


deepstream-app -c deepstream_app_config_ssd_rtsp_fp32.txt


(55-56 FPS)


deepstream-app -c deepstream_app_config_ssd_fp16.txt


(25-26 FPS - max FPS)


deepstream-app -c deepstream_app_config_ssd_rtsp_fp16.txt


Comparison of Results

Xavier NX - Video Results (1080p, 60 FPS) FP32 -> 12-13 FPS * 4 (48-52 FPS)

FP16 -> ~36 FPS * 4 (~144 FPS)

Xavier NX - RTSP Results (1080p, 25 FPS) FP32 -> 12-13 FPS * 4 (48-52 FPS)

FP16 -> ~25 FPS (max) * 4 (~100 FPS)

AGX Xavier - Video Results (1080p, 60 FPS) FP32 -> 21-22 FPS * 4 (84-88 FPS)

FP16 -> 55-56 FPS * 4 (220-224 FPS)

AGX Xavier - RTSP Results (1080p, 25 FPS) FP32 -> 21-22 FPS * 4 (84-88 FPS)

FP16 -> 25-26 FPS (max) * 4 (100-104 FPS)
