What's New in Raspberry Pi 4 - It's Specifications and Features

In last year, the final iteration of ‘classic Raspberry Pi” was launched, we can say it an evolution rather than a revolution. Both of the models of Raspberry Pi 3, i.e. Model A+ and Model B+ boards wrung the last bits of available performance out of the platform. Since starting, it was cleared that the Foundation would have to do something interesting than the last time around. Before knowing the features and specifications of Raspberry Pi 4, let me introduce you with “What is Raspberry Pi”?

 

Basically, Raspberry Pi is a low cost, credit card sized computer that can plug into a computer monitor or TV and uses a standard mouse and keyboard. The little device enables people to explore computing and learn how to program in languages like Python and Scratch. The single board computer is able to do everything that you’d expect from a desktop computer, i.e. from browsing the internet and playing the high quality video to making spreadsheets, playing games and word-processing. Moreover, Raspberry Pi has the ability to interact with the outside world and has been used in a wide array of digital maker projects from machines, music and patent detectors to weather stations and tweeting birdhouses with infra-red cameras. You can see that Raspberry Pi is being adopted by kids across the world in order to learn programs and build up an understanding of how computers work.

 

We all were assuming that it would take some time; individuals weren’t actually thinking about the updated and new version of Raspberry until for next year. But, we got surprised before some days ago with Raspberry Pi 4. The new Raspberry Pi 4 is a totally different beast, despite its surface which a lot looks like previous models of Raspberry Pi. There are some radical architectural changes here from earlier Raspberry Pi boards.

New Raspbain Software

A radically refurbished operating system is released based on the forthcoming Debian 10 Buster which enables to support Raspberry Pi 4. It carries out several technical improvements behind the scenes with an extensive modernized user interface and the updated application includes Chromium 74 web browser. Hence, it is advised for those who are willing to go with Raspbain Buster right away. On this sense, we strongly recommend you to download the new image instead of updating the current card. The Mesa “V3D” driver developed by Eric Anholt at Broadcom is used in Raspberry Pi 4over the last five years. Benefits of the software include – OpenGL-accelerated web browsing and desktop composition with the ability to run 3D applications in a window under X. The software also diminishes roughly half of the lines of closed source code in the platform.

 

Have a look at new features:

 

The Processor –

In Raspberry Pi 4, there is an encapsulated processor that acquires the same heat spreader for better thermal control because their earlier model may look similar from outside. As the Raspberry Pi 3 was built with a Broadcom BCM2837 processor and a quad-core Arm Cortex-A53 clocked at 1.4GHz, the new one is made up with Broadcom BCM2711 and 64-bit quad core Arm Cortex-A72 clocked at 1.5 GHz. However, it doesn't seem as crucial because there are already some distinctions between core architectures of these two processors.

 

While the A53 was designed as a mid-range core, and for potency, the A72 may be a performance core, thus despite the apparently little distinction in clock speed, the important performance distinction between the cores is absolutely rather vital. It is overviewed that, the new Raspberry Pi4 runs faster than ever, more than fast enough that it replaces the desktop for an average user.

USB and Ethernet-

However, in all probability, the foremost noticeable distinction from previous models is that the silicon chip LAN7515 that acted because the USB hub Associate in Nursing a local area network Controller for the Pi, is missing from the new board. In its place is that the VLI VL805 that provides a USB three.0 Hub over a PCI specific bus. The PCI Express Bus provided by the new BCM2711 implies that it is having the capability of 3.0 USB and moreover Gigabit Ethernet is now providing the Broadcom BCM54213PE on a separate bus to the USB traffic. It signifies that instead of being throttled as we tend to saw with the Raspberry Pi three, Model B+, the new Raspberry Pi four has ‘real’ Gigabit local area network. Yes. You detected that right. The new Raspberry Pi board has each ‘real’ Gigabit LAN and 2 USB three.0 ports likewise as a few additional ‘legacy’ USB two ports.

 

Wireless support-

Raspberry Pi4 also provided wireless support, it is an RF Shielded module by the same Cypress CYW43455 chip which you can see on Raspberry Pi 3, Model B+. Moreover, it is also offering dual-band 2.4 GHz and 5GHz IEEE 802.11.b/g/n/ac wireless networking as well as Bluetooth 5.5 and Bluetooth LE. For completeness, the ultimate massive little bit of silicon—located simply to the correct of the most processor package—is the LPDDR4 SDRAM for the board that comes within the form of a micrometer FBGA-packaged chip, and this can be wherever another massive distinction from previous Raspberry Pi models shows its head.

 

The Memory-

In order to complete the final bit if silicon, it is located just the right of main processor package. The LPDDR4 SDRAM for the board which comes in the shape of a Micron FBGA-packaged chip and this is where another big difference from previous Raspberry Pi models shows its head. Not as same as any previous board, the new Raspberry Pi 4 is now available in three distinct models, among which each offers a different memory option, such as – 1GB, 2GB, and 4GB of RAM.

 

Powering the Boards-

Another huge distinction is that the power jack, gone is that the small USB jack from previous models, and in its place may be a USB-C jack. It’s an evident amendment. The tolerances on the facility offer for the Raspberry Pi three, Model B+, were already pretty skinny, and therefore the new board will need up to three Amps, that’s not one thing that the previous small USB offer may give.

 

A New Official Power Supply-

With the switch from small USB to USB-C comes a replacement official power offer. but whereas USB-C chargers generally retail for anyplace between $10 to $60, the new 15W official offer is priced at simply $8, that is kind of market breaking. as a result of lots of folks that have not even detected of Raspberry Pi can pass away at that value purpose. Also, just like the original small USB offer, the new USB-C power offer has been designed as an influence offer, not a charger.
