4GB vs 2GB

Comparison between Jetson Nano 2GB and Jetson Nano 4GB

ARMv8, ARMv9

  • https://en.wikipedia.org/wiki/ARM_architecture_family
  • ARMv8 is an ARM instruction set architecture announced in 2011. It brought a large number of fundamental changes to the instruction set, including the introduction of 64-bit operating capabilities. ARMv8 architecture uses two execution states, AArch32 and AArch64. As the names imply, one is for running 32-bit code and one for 64-bit.
  • After ARMv8, which was introduced in 2011, ARM introduced ARMv9 architecture.
  • According to ARM, some of the major new features of the ARMv9-A architecture include Realm Management Extension (RME) and Embedded Trace Extension (ETE) and Trace Buffer Extension (TRBE).
  • Apple M1 chip or M2 chip is based on ARMv8.5-A instruction set architecture.

Vs Raspberry Pi 4

The two motherboard are similar:new Raspberry Pi has the same arch and almost the same processor (nvidia one is older). VLC doesn’t work on Nvidia Jetson Nano

GPU benchmark

  • Glmark2. Glmark2 is an OpenGL 2.0 and ES 2.0 benchmark. glmark2 is a cross-platform tool that can be used to test the performance of the GPU on both platforms with and without CUDA cores.
    • sudo apt-get install glmark2

GStreamer, gst-launch-1.0

  • Jetson Nano + Raspberry Pi Camera
  • To test 4K video playback on the NVIDIA Jetson Nano, you can use the GStreamer multimedia framework. See ACCELERATED GSTREAMER USER GUIDE 
    sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo apt-get update
sudo apt-get install gstreamer1.0-tools gstreamer1.0-alsa \\
   gstreamer1.0-plugins-base gstreamer1.0-plugins-good \\
   gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \\
   gstreamer1.0-libav
sudo apt-get install libgstreamer1.0-dev \\
   libgstreamer-plugins-base1.0-dev \\
   libgstreamer-plugins-good1.0-dev \\
   libgstreamer-plugins-bad1.0-dev

gst-launch-1.0 filesrc location=<4k-video-file-path> ! qtdemux ! h264parse ! omxh264dec ! nveglglessink -e

    Replace <4k-video-file-path> with the path to your 4K video file. Note that the performance of 4K video playback may depend on other factors such as the bitrate of the video, the overall load on the Jetson Nano, and so on
