NVIDIA Jetson Orin Nano- SoM Overview

This section provides an overview of the Orin Nano SoM components and their capabilities.

The NVIDIA Jetson Orin Nano, delivers up to 40 tera operations per second (TOPS) on a 15W package. The Orin Nano System on Module (SoM) is a small PCB, that is similar in size to laptop memory stick. It encapsulates the computing devices such as the 6 Core ARM CPU and the, up to 1024 CUDA Cores GPU, it also holds the LPDDR5 memory packages. On Figure 1, we have the SoM.

Table 1 shows a summary of the hardware characteristics of the SoM:

Graphics Processing Unit (GPU)

The Orin Nano comes with an NVIDIA Ampere architecture GPU. The Ampere GPU brings state-of-the-art graphics and parallel computing techniques, such as ray-tracing, CUDA, and TensorRT support. The Orin Nano 8 GB Ampere GPU is composed of the following modules:

2 Graphic Processing Clusters (GPCs)
8 Texture Processing Clusters (TPCs)
16 Streaming Multiprocessors (SMs), where each has:
- L1 cache of 192KB
- L2 cache of 4MB
- 128 CUDA cores
- 4 Tensor cores (3rd generation)

Central Processing Unit (CPU)

Jetson Orin Nano comes with 6 Arm Cortex-A78AE CPU cores, with the following configuration:

64KB instruction L1 cache
64KB data cache
256KB L2 cache
Up to 1.5 GHz frequency

The CPU cores are arranged in 2 clusters, one with 4 CPU cores, and other with 2 Cores. Each cluster has a 2MB L3 Cache. The CPU complex also features a 4MB system cache.
