Unboxing

This article corresponds to the video tutorial, which can be viewed by clicking the link at the end of the article.

Improvements compared to 3B include:

1. CPU frequency increased from 1.2GHz to 1.4GHz

2. Better overall heat dissipation

3. WIFI supports dual-band 2.4GHz and 5GHz, providing better connection stability

4. Supports low-power Bluetooth 4.2

5. Ethernet supports POE and faster transmission speeds

Is the previous tutorial applicable to 3B+?

Since 3B+ has less support for systems than 3B, it currently only supports the official system and the 64-bit system released by our public account. Therefore, some tutorials that require installing other systems, such as making a game console, cannot be completed with 3B+. However, most tutorials are fully applicable.

Special note: Our public account has provided two official systems. Please use the new system for Raspberry Pi 3B+. Reply with “Raspberry Pi New System” to obtain it. The old version system is not applicable to 3B+.

How to choose when buying?

If you are a beginner wanting to explore more interesting projects without spending too much, you can choose 3B. If your project has higher performance requirements, you can choose 3B+.

Performance Testing Comparison Results

1. Single-thread performance test

(The above image is 3B, the below image is 3B+, same below)

2. Multi-thread test

3. Mutex test

4. Thread test

Note: If you have questions about the testing methods and results, please watch the Raspberry Pi performance testing tutorial, which provides a detailed introduction and will not be repeated here.
