Raspberry Pi 4 or Raspberry Pi 3B+, which one is better?

Are you considering buying a Raspberry Pi but find yourself torn between the latest models? With the Raspberry Pi ecosystem continually expanding, choosing the right model can be daunting. Two popular options, the Raspberry Pi 4 and the Raspberry Pi 3B+, offer different features and performance levels, catering to a variety of needs. In this comparison, we’ll delve into the key differences between these models to help you make an informed decision.

Raspberry Pi 4 vs Raspberry PI 3B+: CPU, RAM, and Graphics

When it comes to processing power, RAM, and graphics capabilities, the differences between the Raspberry Pi 4 and Raspberry Pi 3B+ are quite apparent. The Raspberry Pi 4 boasts a quad-core ARM Cortex-A72 CPU running at 1.5 GHz, which is a step up from the Raspberry Pi 3B+’s quad-core ARM Cortex-A53 CPU at 1.4 GHz. This difference results in significantly improved performance for computing-intensive applications.

In terms of memory, the Raspberry Pi 4 offers options with 2GB, 4GB, or 8GB LPDDR4 SDRAM, giving users much more flexibility and potential for multitasking and handling more complex tasks. The Raspberry Pi 3B+, on the other hand, is restricted to 1GB LPDDR2 SDRAM, which might be limiting for more demanding operations.

As for graphics, the Raspberry Pi 4 moves forward with the VideoCore VI graphics processor that supports OpenGL ES 3.x. This allows for better handling of modern graphical applications and tasks, something that the Raspberry Pi 3B+ and its VideoCore IV graphics processor supporting OpenGL ES 2.0 might struggle with. This advancement opens up new possibilities for users looking to work with high-performance graphical output.

Performance Benchmarks: Raspberry Pi 3B+ vs Raspberry Pi 4

In head-to-head benchmark tests, the Raspberry Pi 4 consistently outperforms the Raspberry Pi 3B+. With faster CPU performance, as evidenced by benchmarking tools like Sysbench, to superior graphics handling thanks to its more advanced GPU, the Raspberry Pi 4 is the clear leader in terms of raw power.

When it comes to real-world applications, users will notice that the Raspberry Pi 4 handles complex tasks such as video processing and computation much more efficiently. Gaming performance also demonstrates a noticeable improvement, with support for more modern OpenGL standards opening the door for future advancements in Raspberry Pi gaming capabilities.

A major leap in performance is observed in the Raspberry Pi 4’s ability to read and write data to external USB drives, with its USB 3.0 ports providing transfer speeds vastly superior to the USB 2.0 ports found on the Raspberry Pi 3B+. This enhancement alone changes the game for users requiring fast data processing and transfers.

Connectivity Advancements: Ports and Wireless Capabilities

The Raspberry Pi 4 features numerous connectivity upgrades over its predecessor. With the addition of two USB 3.0 ports, users will experience higher data transfer speeds for connected devices. Wireless connectivity also sees improvements with the inclusion of Bluetooth 5.0, offering a longer range and faster data transfer rates than the Bluetooth 4.2 found on the Raspberry Pi 3B+.

Furthermore, the Raspberry Pi 4 introduces dual-HDMI ports, supporting 4K resolution on one port, thereby enabling the use of multi-monitor setups – a significant improvement over the single 1080p output of the Raspberry Pi 3B+.

Power Requirements and Thermal Management

Power requirements and thermal management are crucial considerations when choosing between the Raspberry Pi 4 and the Raspberry Pi 3B+. The Raspberry Pi 4’s upgraded hardware demands a more robust power supply, capable of delivering at least 3A, compared to the Raspberry Pi 3B+ which can run on a 5V / 2A power source.

The increased power requirement of the Raspberry Pi 4 results in higher power consumption and heat generation. To prevent overheating and potential damage to the board, users should consider investing in additional cooling solutions such as heatsinks and fans. These accessories help dissipate heat more effectively, ensuring stable performance and longevity of the Raspberry Pi 4.

When selecting a power supply for the Raspberry Pi 4, it is essential to choose one that meets the recommended specifications to avoid issues related to insufficient power delivery. Additionally, regular monitoring of the board’s temperature is recommended, especially during heavy usage, to ensure optimal performance and prevent overheating.

In summary, the Raspberry Pi 4’s increased power requirements and thermal management needs should be taken into account when considering its suitability for your project. Proper power supply and cooling solutions are essential to ensure stable operation and longevity of the device.

Conclusion and Decision-Making Criteria

When deciding between the Raspberry Pi 4 and Raspberry Pi 3B+, it’s crucial to consider the requirements of your specific project. The more advanced features of the Raspberry Pi 4 may be necessary for high-demand tasks and those seeking the best performance available on the Raspberry Pi platform. However, the Raspberry Pi 3B+ remains a valuable option for projects with more modest requirements and budgetary restrictions.

It’s essential to assess the demands of your application, including processing speed, graphics needs, connectivity options, power consumption, and budgetary constraints, to make an informed decision on which Raspberry Pi model to choose. Both models continue to expand the Raspberry Pi ecosystem, offering users a broad range of options tailored to their unique project needs.
