Raspberry Pi 4 vs NVIDIA Jetson Nano, Which one is better for your project?

Raspberry Pi and NVIDIA Jetson Nano are the most well-known devices for AI development projects. In March 2019, NVIDIA released the Jetson NANO developer kit, which is an ideal, affordable manual smart computer for manufacturers, DIY, students, and other embedded developers. Since then, the Raspberry Pi also released a new product, the Raspberry Pi 4, which made a full range of performance improvements compared to the 3-generation Raspberry Family.

Upon initial comparison, it appeared that they basically have the same features, with the Nano having an additional dedicated GPU on the board. Let’s compare the two boards and see what all the differences really are. This will be helpful for you to make a decision on the development project.

Raspberry Pi 4B

The Raspberry Pi 4B is a “plug-and-play” board computer, which is also a good starting point for learning AI artificial intelligence projects. Based on the Linux operating system, you can use a large number of Linux-free software and tools.

Raspberry Pi 4B is suitable for people of all ages, such as programming languages like Python. At the same time, it can also do everything you expect, like browsing the web, playing HD video, making spreadsheets, performing text processing, and playing games.

Compared to the previous Raspberry Pi 3 B+, the Raspberry Pi 4 B contains the following upgrades:

  • Faster processor: CPU upgrades to quad-core Cortex-A72 (ARM V8) 64-bit SOC @ 1.5 GHz.
  • More memory: LPDDR4-2400 SDRAM provides multiple models such as 1GB, 2GB, and 4GB RAM.
  • Double 4K graphics card: 2 mini HDMI ports can output 4K video, even support double displays.
  • 2 USB 3 and 2 USB 2 ports: New version has 2xUSB 3 ports, which can be connected to peripheral devices at a higher speed;
  • USB-C Power: The power connector of the board is upgraded from Micro-USB to the USB-C connector.
  • I / O: 40-pin GPIO connector (support I2C, SPI, and UART).

The above is the main difference between the new RASPBERRY PI 4 and the old Raspberry PI 3. Compared with the old motherboard, the new version of Raspberry PI 4 has higher processing capabilities and other advantages.

NVIDIA Jetson Nano

Jetson Nano development board is also a powerful small artificial smart computer, which only needs to insert a MicroSD card with a system image to start, built-in SOC system-level chip, can have a parallel hand, such as Tensorflow, Pytorch, Caffe / Caffe2, Keras, MXNET and other neural networks that can be used to achieve functionality such as image class, target detection, speech segmentation, and intelligent analysis. Usually used to build autonomous robots and complex artificial intelligence systems.

The following is the core specification of the NVIDIA Jetson Nano Developer Kit:

  • CPU: Quad-core ARM CORTEX-A57 MPCORE processor
  • GPU: NVIDIA MAXWELL W / 128 NVIDIA CUDA core
  • Memory: 4 GB 64-bit LPDDR4
  • Graphics: HDMI and DisplayPort output
  • USB: 4 USB 3 ports
  • I / O: I2C, SPI, UART, and GPIO connector compatible with Raspberry Pi

NVIDIA Jetson Nano Developer Kit provides all computing power required when designing prototypes (also integrated GPU).

Cortex-A72 VS Cortex-A57 CPU Comparison

The Raspberry Pi 4B uses a 4-core Cortex-A72 architecture of CPU with a frequency of 1.5GHz, while Jetson Nano uses a 4-core Cortex-A57 architecture CPU with a frequency of 1.43GHz.

See the table below for specific parameters:

L2 cache 512 KiB to 4 MiB 512 KiB to 2 MiB
L3 cache None None

According to official information, Raspberry PI 4B Cortex-A72 is about 50% faster than the previous generation of Raspberry PI 3 B + Cortex-A53 processors, while NVIDIA Jetson Nano is located between the Raspberry PIs between two generations of CPUs.

In fact, they are actually very similar in primary functions, and all can develop some special functions, such as ARM processors, 4GB RAM, and a series of peripherals.

The biggest difference is that the Raspberry Pi has a low-power VideoCore multimedia processor, and Jetson Nona contains higher performance, more powerful GPUs (graphics processors), which makes it support some functions that Raspberry Pi Can’t do. Then Jeston Nona makes some more depth developments possible and have more potential in development.

Raspberry Pi 4 vs NVIDIA Jetson Nano Specification Comparison

After a comparison of the CPU performance, let’s take a detailed comparison of the specifications of the Raspberry PI 4 and NVIDIA Jetson Nano Developer Kit.

The main features of Raspberry PI 4 and NVIDIA Jetson Nano are very similar. And the above is not a full function list, so there are some differences that do not appear in the above table.

They both have ARM processors, 4GB RAM, and a series of peripherals. NVIDIA Jetson Nano has 128 CUDA core NVIDIA MAXWELL GPUs that are actually comparable to GPU (Cortex-A57) in the Nintendo Switch Game console. NVIDIA Jetson Nano’s CPU and GPU hardware are very close to Nintendo Switch, except for NVIDIA TEGRA X1 SOC (on-chip system) hardware in Nintendo Switch, and four Cortex-A53 kernels. This undoubtedly enhances the potential of NVIDIA Jetson nano.

Note: Raspberry Pi 4 vs NVIDIA Jetson Nano Developers kits is shortage from the end of 2021 to now, because of the shortage of chips and the original factory closed. The price fluctuations almost every week.

Recently, NVIDIA released the updated version of the Jetson Nano development kit, which supports 2 MIPI CSI cameras, which can extend more machine visual applications.

Like the Raspberry, Jetson Nano also has complete communication connectors, like GPIO, I 2 C, I 2 S, SPI, and UART.

  • I2C: I2C is a serial protocol for connecting low-speed devices such as embedded systems such as microcontrollers, EEPROMs, A / D, and D / A converters, and I / O interfaces.
  • UART: Universal asynchronous transceiver allows your device to connect to a serial section. The UART pin is marked as TXD and RXD.
  • SPI:  Serial Peripheral Interface is a synchronous serial communication interface specification for short-range communications, mainly for embedded systems. The SPI is marked as MOSI, MISO, SCLK, CE0 and CE1.

Easyibility & Resource Comparison

First, the easibility, of Raspberry Pi will be more suitable for a beginner.

The Raspberry Pi 4B is easier and with more resources, which is suitable for most people. You can easily find a solution for most problems. If you are new to the artificial intelligence field or want to start a small project for competition, build a platform, or use it to learn Python programming, the Raspberry Pi will be a better choice. As there is more information on the website and it’s relatively easy to get on.

Jetson Nona’s performance is superior to the Raspberry Pi, which is very advantageous in AI and deeply learned. If you need to build an AI or a machine learning project, Jetson NANO with full GPU may be the most ideal choice. But it will be more difficult to get started and require a certain basis. If you want to learn deep AI learning, the practicality of Jetson Nano will be bigger, whether it is a robot, aircraft, or intelligent car, the Jetson Nano will work better than the Raspberry.

Second, Jetson Nano provides more resources on neural networks and depth learning.

NVIDIA spent ten years establishing and promoting an artificial intelligence platform, which aims to help engineers and data scientists train, optimize and deploy neural networks.

Engineers and data scientists use different frameworks for different applications. At the beginning of our test, Jetson Nano supports currently popular depth learning frameworks, including Tensorflow, Pytorch, MXNET, KERAS, and CAFFE.

Note NVIDIA Open Source Robot JetBot project is Tensorflow.

On Jetson Nano, users can match the NVIDIA TENSORRRT reasoning engine, the optimization of mixing accuracy, which easily pushes up the reasoning performance again. With NVIDIA supports Caffe, Tensorflow, and Torch’s Digits Depth Learning Server, users can easily train their (or others), and easy to transplant them to Jetson Nano to execute the exclusive application, this has the opportunity to reduce the developer’s 70 % R & D time.

Summary

After the comparison, the features provided by Raspberry Pi 4 vs NVIDIA Jetson Nano are almost identical. You should consider the hardware specs, and of course, price to determine which board best fits your needs. Both of these boards run Linux and have pretty much the same capabilities, but if you need to build Artificial Intelligence (AI) and Machine Learning (ML) projects, then the NVIDIA Jetson Nano has a full-blown GPU and will likely be the board chosen.

Note: Raspberry Pi 4 vs NVIDIA Jetson Nano Developers kits is shortage from the end of 2021 to now, because of the shortage of chips and the original factory closed. The price fluctuations almost every week.
