Fans are eagerly awaiting the follow-up of the Raspberry Pi 3 B+, but how far is it?
The impact of Raspberry Pi on computing is undeniable. Microcomputers allow anyone to use credit card sized devices to build their own settings from scratch for $35, adding any sensors, ports and peripherals they want.
The Raspberry Pi was originally developed by a team of college students led by Eben Upton. Their overall mission is to develop a computer for curious children and to be passionate about creating their own computers.
The Raspberry Pi was originally designed to teach children how to code, and its low-cost, easy-to-use interface has now evolved into the device of anyone who is passionate about experimentation. It has proven to be very popular with hackers, coders and other technicians who are determined to push the microcomputer to the limit.
In the past seven years, Raspberry Pi computers have grown rapidly. The latest addition to the lineup is the B+ variant of the Raspberry Pi 3, which received five stars and editorial selection awards in our review.
The next important release might be the Raspberry Pi 4, which has been rumored for a long time. But as micro-computers get smaller and smaller every time, consumers' demands are getting higher and higher. What are our expectations for the next-generation Raspberry Pi?
Raspberry Pi 4 release date and availability
When the Raspberry Pi 3 was first introduced, creator Eben Upton told IT Pro that the device's shortest life could be three years, mainly because the company has reached the limit of 40nm manufacturing process. This means that the next major Pi update will not be realized until 2019.
As the Foundation effectively reaches the limits achievable with the 40nm manufacturing process, the new Raspberry Pi 4 is likely to be delayed. However, Upton did not give up and said: "We will eventually get there."
However, this did not prevent Upton and Co from releasing an updated version of Pi 3 two years later. With improved connectivity and faster clock speeds, the Raspberry Pi 3 B+ is a mid-term update that surprises everyone and proves to be a great complement to the Raspberry Pi series.
However, unfortunately, this does not mean that the Raspberry Pi 4 will appear soon. We have not heard of the potential successor to Pi 3 B +, so it seems that we will not see one until 2019 - or later. It is worth noting that although the performance of Pi 3 B + is better than its predecessor, this is largely due to the increased power efficiency, and the company is still welcoming the technical limits of 40nm manufacturing.
Raspberry Pi 4 Specifications and Features
In view of the problems faced by the development, there is still no news about the technical specifications that may appear in the Pi 4. Given the company's efforts to improve current 40nm performance, we are likely to see a shift to alternative manufacturing processes that provide more efficient silicon.
As for the features, the Raspberry Pi 3 B+ already includes excellent Bluetooth and Wi-Fi support, so we are unlikely to see any substantial network upgrades. Considering the team's focus on interoperability between Pi generations, you can also expect the form factor to remain the same.
The port is an area where we may see some real changes. For example, the Thunderbolt 3 compatible USB Type-C port can handle power, data and video transfers - which means that a USB-C port can do the work on the existing inputs on the Pi 3. They are also much smaller than the full-size USB Type-A port, giving the Pi 4 a slimmer form factor.
Raspberry Pi 4 pricing
One of the main reasons why the original Raspberry Pi is so cheap is that it is designed to be affordable for parents whose children want to enter the computer. This mission statement remains at the heart of everything the Raspberry Pi Foundation does, so we don't want the price of the Raspberry Pi 4 to rise sharply. Creator Eben Upton has been very determined to keep the price as close as possible to $35.
