Raspberry Pi 5

Waiting for the release of Raspberry Pi 5…

It’s been two years and six months since the Raspberry Pi 4 model B was released.

At the time of launch, CPU performance was a little disappointing, but I think it was a great consideration to be able to choose up to 8GB of RAM capacity.

In the case of Raspberry Pi, it was a common cycle for the new model to be released within two years of its release, but this time it is not following it.

Of course, I am not dissatisfied with the performance and use of the Raspberry Pi 4 model B, but it is unusual for the next model to not be released after two years.

The reason why it’s not being released

It was written speculative by synthesizing the situations mentioned in various communities, so please pay read lightly.

Among the many reasons why Raspberry Pi 5 is not being released, the most convincing thing is that the Raspberry Pi 4 model B and the Compute Module 4 sell too well.

The Raspberry Pi 4 product line is sold so well that the Raspberry Pi Foundation does not feel the need to release the next model immediately.

This is bound to be a difficult situation for consumers who want to experience the next model with upgraded performance than now.

In addition, I think the difficulty in global semiconductor supply and demand due to the influence of COVID-19 is also playing a part.

In South Korea, prices continue to rise and cannot be purchased freely, perhaps due to the lack of imports of the Raspberry Pie 4 Model B.

Raspberry Pi 5 specification that the market wants

Then, what specifications does the market want the Raspberry Pi 5 to be released with?

Let’s find out how much the market expects for major parts.

CPU

The CPU will use the Broadcom quad ARM processor as before and expects the processing speed to exceed 2 GHz.

As the processing speed increases, it seems that a CPU heat sink containing a heat pipe to withstand heat generation should be installed as a default.

RAM

RAM will adopt the latest generation, LPDDR5 SDRAM, and you can choose the capacity like the Raspberry Pi 4 model B, and I think the capacity you can choose will range from 2GB to 16GB.

USB-C

As a power supply method, we expect to adopt a further improved USB-C type, even due to the initial issue of the release of the Raspberry Pi 4 model B.

Storage

In addition to the microSD card, which is a currently available storage device, integrating eMMC memory into the board will provide more improved read/write capabilities, secure data protection, and improve the durability of the storage device.

Also, one of the additional advantages of adopting eMMC memory is that data input/output is faster.

Display

Raspberry Pi 4 Model B adopted dual Micro HDMI as display input/output.

There was an inconvenience of having to use the Micro HDMI To HDMI cable to output external displays, but we hope to eliminate this inconvenience by adopting the HDMI terminal again.

The current version supported 4K30fps in dual display mode and 4K60fps in single display mode when outputting external displays. I hope that the next version will support 4K60fps in dual display mode.

Addressing the issue of heating of USB hubs and Ethernet chips

It is known that some heat problems occurred even when the VIA Labs VL8054-port USB hub and LAN9512 Gigabit Ethernet controller adopted in the Raspberry Pi 4 Model B were not powered on.

If the Raspberry Pi 4 model B generates heat without operating, the lifespan of the semiconductor chip mounted on the board may be reduced, so this issue is not expected to occur in Raspberry Pi 5.

Conclusion

The specifications of the Raspberry Pi 5 we want may be too high for the manufacturer to apply, and it seems inevitable to raise the price.

However, in order to save trial and error time and focus more on developing IoT systems, several specifications mentioned above are essential.

It may be a difficult expectation, but manufacturer hope to launch the Raspberry Pi 5 that can meet all of these improvement specifications.
