Raspberry Pi 3 B vs Raspberry Pi 3 B+
If you’re a fan of the Raspberry Pi, you must’ve noticed something strange with the naming. Following most models, you’ll usually find letters A, B, and B+. With the Pi Compute and Pi Zero being exceptions.
The reason for this strange naming convention is simply the board. Interestingly, engineers used the B-board credit card as the original Raspberry Pi. However, the slightly squarer and smaller A board quickly followed suit.
Plus, there have been several revisions to the B board, leading to the B+ name. For the Raspberry Pi 3 models, the B+ name means the model has higher specifications but keeps most of the hardware.
If you’re planning to buy a Raspberry Pi 3 B+ or Raspberry Pi 3 B, you might find it hard to choose. Why? Because both boards have similar prices.
However, a closer look at the specifications will help you decide which one is better for a project.
Raspberry Pi 3 B Specifications
The Raspberry Pi 3B has features that make it capable of handling almost any task. It uses an ARMv8-A 32/64-bit instruction set with a BCM2837 system on a chip. Plus, it comes with a 4-core CPU (Cortex A-53) and GPU with up 1.2 GHz speed. Also, you’ll get 1 gigabyte of ram.
The Raspberry Pi 3 B is the first Pi board with built-in wireless and significant upgrades.
Raspberry Pi 3 B+ Specifications
The Raspberry comes with everything you can find on the Raspberry Pi 3 B, but better. Equipped with a 1.4 GHz ARM Cortex A-53 CPU with GPU, the Pi 3 B+ is ready to give you the speed you need for your operation.
Additionally, the ARMv8-A 32/64-bit architecture uses a different SoC model, supporting 1 Gb of RAM.
Interestingly, the 3 B+ model also features an improved PXE network booting. However, you’ll still get fast booting with USB storage.
Also, the 3 B+ models come with improved thermal management while unlocking new possibilities. However, you’ll need a heat sink and other forms of cooling to get the most out of this.
Lastly, the Pi 3 B+ comes with an improved Power Management IC (PMIC) that gives you a better dynamic voltage scaling. As a result, you can improve performance and data control with the Raspberry Pi 3 B+.
Raspberry Pi 3 B vs Raspberry Pi 3 B+: Hardware Comparisons
Now, let’s compare the hardware of both Pi 3 B models.
The 3 B and B+ use the same 32/64-bit processor (four cores). The similarity also stretches down to the same ARM Cortex A-53 architecture.
However, the 3 B+ benefits from an increased CPU speed clocking at 1.4 GHz. Also, it’s 16.7% faster than the original 1.2 GHz of the 3 B model.
While you can only use 2.4Ghz WIFI with the Pi 3 B model, the 3 B+ model supports a dual-band wireless antenna that gives you access to faster WIFI speeds. Plus, you can get both 2.4GHz and 5GHz 802.11 b/g/n/ac WIFI.
Moreover, the 3 B+ can reach a throughput speed of up to 100 mb/s, two times faster than the Pi 3 B.
In addition, the 3 B+ module supports 5G frequencies and Bluetooth upgrades.
The 3 B+ features a new Gigabit Ethernet USB 2.0 bridge that upgrades your Ethernet controllers. It also has an improved rate and maximum throughput speed of 300 Mb/s.
Plus, its ethernet cable supports the Power over Ethernet interface (PoE), ideal for powering the 3 B+.
As we mentioned earlier, the power management on the 3 B+ is an improved version of what you’d get on the Pi 3 B model.
Here’s a more detailed explanation; the Pi 3 Model B+ utilizes MxL7704 power management to produce five outputs. These output voltages include 1.8v, 3.3v, 1.2v, VDD_Core, etc.
Raspberry Pi 3 B+’s Compatibility With Accessories
No doubt, many Raspberry upgrades have failed due to compatibility issues, especially with the power supply units. But, the Pi 3 B+ seems to be more compatible with accessories than the Pi 3 B.
So, the general rule of thumb is to ensure to use appropriate MicroSD card in the event of USB problems. Plus, you must have a fast SD card with dependable error correction software.
Also, ensure you have a suitable power supply unit. For improved performance, we recommend using the official Pi supply unit.
Choosing Between Raspberry Pi 3 Model B and 3 B+
Choosing between the two Pi 3 Models could be tricky. Why? Because most times, you’re usually confused between choosing “price” or “high quality.”
But here’s what we recommend:
The 3 B is an excellent device for almost any task. However, the Pi 3 B+ seems to be a better option for handling fixes. Slap in a faster processor and better network support, and the Raspberry PI 3 B+ would do a better job than the PI 3 B.
The Raspberry Pi 3 B+ offers improved hardware specifications. As a result, it can make your existing and new projects work better.
Also, the Pi 3 B+ is an excellent choice for handling Raspberry Pi 4 model projects.
However, if you need a smaller and lighter computer for your project, the Pi 3 B would be enough.
In the end, it all balls down to your specific needs.
