New Cheap Pocket Size Computer – Raspberry Pi 4


The new cheap and next-generation pocket computer Raspberry Pi 4 is now available in the market, with much more computing features and new options.

The latest technology, The Raspberry Pi on 24th June launched the Raspberry Pi 4 – the mini or pocket computer, an all-inclusive upgrade that includes almost everything of the computing world.

Raspberry Pi 4 provides the option to the users to use up to three RAM memories. The basic 1 GB RAM has the following prices according to its RAM size:

  • 1 GB RAM – $35
  • 2 GB RAM – $45
  • 4 GB RAM – $55

All the above modules have been launched on June 24, 2019. The performance of modules of more than 2 GB RAM can be increased over time to match the demand of any required application.

The up-gradation of existing Pi 3 to 4 is possible while retaining the performance of the latest Raspberry Pi modules, as said by Eben Upton, Raspberry Pi co-founder.

The latest features make Pi 4 the most powerful computing device, as said by Charles King, chief analyst at Pund-IT. Typically, the hobbyists, the developer class and educational institute use these modules. This latest Pi 4 modules have offered more advanced usage options and opportunities.

“The superior functions and performance enable these devices to compete more successfully with PC top-class devices, such as Celeron and Intel Atom. It can provide more opportunities for Arm and Raspberry among companies offering IoT platforms that are seeking a replacement to x86,” King said LinuxInsider.

Faster Speed and Better Performance

The Pi 4 platform is faster and offers better capability such as double-screen and 4K compatibility. It offers three-time better processing speed and four-time better multimedia functionality as compared to old Pi 3+, in line with the company.

The objective of the up-gradation is to offer a full-level computing performance with one-tenth better capability as compared to a traditional desktop computer, stated Upton.

Raspberry Pi 4 offers full general purpose performance for most computer users.

Small-Sized Powerhouse

The small wallet sized Pi minicomputer has OS on board without any need to install it separately. The company is also offering a full minicomputer kit including monitor, keyboard, mouse, power supply, cables, SD card and case plastic body for just $120.

Regardless of its key target users in the education sector, the Raspberry Pi platform has increased in power during the last decades. It is a powerful device for the developer community, as said by Simon Ritter, deputy CTO of Azul Systems.

“We’ve found that people are using this platform for about everything they can imagine, from the control of robots to maintain a scoreboard for sorts matches to machine level apps playing Minecraft.

Strong Competitor Rising

Its high power is also very much appealing to many users. The 64-bit platform and the option to install up to 4 GB RAM have made it able to do really important tasks, added Ritter.

“Using double 4K displays, Ethernet network port and USB 3 is surprisingly great,” he said.

Raspberry Pi case

These new features can make sure that the Raspberry Pi could be able to suit the platforms regarding the Internet of Things. Some users are considering Pi 4 a successful platform in the market for IoT developments and deployments, mentioned Pund-IT’s King.

Demand for Pi 4

User demand for Pi modules will rise as a consequence of the most recent upgrades, Upton anticipated. Growing performance is the company’s approach to growing the base of the users.

“Raspberry Pi 4 has got two times higher predecessor performance, so we expect to get an increased adoption,” he mentioned.

The approach Raspberry Pi’s team offers so much more computing performance in such a little box without any required cooling mechanism and still offer the price tag is extraordinary, remarked Ritter.

Design Details

The Raspberry Pi 4 is like same as old $35 module. In actual fact, the design is a bit better than Pi 1B+.

Raspberry Pi 4 design

This new Raspberry platform has some of the internal appearance changes. It has a lot of essential tweaks to have room for the latest computing features.

For instance, the company developer’s team replaced the power connector from the micro-B USB port to USB-C port. One more design tweak is a double display outputs in the latest board. Other changes are in USB and Ethernet ports.

Raspberry Features

The Raspbian OS and other many applications are also available onboard. For Pi 4, the developer’s team shipped a completely improved OS according to the next Debian 10 Buster launch.

Pi 4 Highlights:

  • A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
  • 1GB, 2GB, or 4GB of LPDDR4 SDRAM
  • Full-throughput Gigabit Ethernet
  • Dual-band 802.11ac wireless networking
  • Bluetooth 5.0
  • Dual monitor support, at resolutions up to 4K
  • 4Kp60 hardware decode of HEVC video
  • Complete compatibility with earlier Raspberry Pi products

Upgrade Caution Issued

The developer’s team suggests rushing to Raspbian Buster only when considering every precaution. They suggest downloading an image in the latest format more willingly than installing the latest card.

This safety measure makes sure that the up-gradation uses all the latest working system. For users who have not so much time to wait, ensure to create a backup.

Also, realize that the developer’s team has retired the legacy graphic driver. Instead, Pi 4 has the Mesa “V3D”.

The Raspberry Pi 4 Casing

One more thing to save a little money is to improve the present Raspberry Pi casing. Remove the right plastic fins and skip panel at one side.

The Raspberry Pi 4 Casing

Up-gradation to Pi 4 module needs another power supply. A good USB-C power supply is surprisingly not easy to find in the market, as said by Upton. Ktec designed an appropriate power supply (5V/3A), now available in the market. You can use Pi 3 power supply with Pi 4 after changing USB micro-B to USB-C.

Upgraded Silicon

All previous Raspberry Pi models rather than Pi 4 have 40nm silicon core on board. The developer’s team upgrades the performance by installing a progressively smaller silicon core (28nm) without increasing the cost.

The power saving possible by the smaller silicon core allowed the developer’s team to change Cortex-A53 with Cortex-A72. This smaller silicon core design can execute more command per clock and offers performance 2-4 time better than Pi 3B+, according to the benchmark.
