Raspberry Pi 4 is a mini computer with a powerful processor which provides a smooth user interface. By using Pi 4, you can write codes, control robots, Build servers, and much more. With Pi 4’s 4GB Ram model, it can be considered as a replacement to desktop. It has been released with many upgrades on comparing with the previous models. Get down into the article to know more about Raspberry Pi 4 Model B and its specifications.

Positives

  • USB 3.0 port
  • Powerful Processor
  • Dual monitor support (4K)

Negatives

  • Often gets warm
  • USB-C support only for power
  • Increased in price

Requirements

  • Power Supply – Raspberry Pi 4 has the USB-C port to connect to a power socket. It needs a power supply of at least 3.0 amps.
  • MicroSD card – It requires a minimum capacity of 8GB to store all its data and Raspbian OS.
  • Mouse and Keyboard – It is necessary to have a mouse and keyboard to use the Raspberry Pi.
  • Desktop screen or TV – You need a screen to display the functions of Raspberry Pi 4. A cable is required to connect the Raspberry Pi and a Monitor or TV (HDMI, VGA, DVI).
  • Optional – Headphones or speakers, Ethernet cable.

Performance

Raspberry Pi 4 works faster than the previous model Pi 3 as it comes with 1.5GHz quad-core Broadcom processor where the Pi 3 has a 1.4GHz processor. It is released with multiple series of RAM – 1GB, 2GB and 4GB (DDR4 RAM). So the speed and performance differ based on the RAM capacity.

On testing with Speedometer to measure the responsiveness of Web apps, Pi 4 marked 15.2, whereas the Raspberry Pi 3 marked 8.9 only, which means double the rate of Pi 3. When you use the device continuously, it gets hot too soon, and you can sense the heat from the covered case.

When it comes to CPU, Raspberry Pi 4 contains VideoCore VI GPU which is much faster than Pi 3. The resolution can be set up to 1080 x 720 with 41.4 fps.

Dual 4K Monitor

Raspberry Pi 4 comes with two mini HDMI port where the GPU has the capacity to run two 4K display monitors on restricting at 30Hz. While the 4K HDMI port is turned on, you can run a 4K monitor at 60Hz and a full HD display monitor at the same time. The only disadvantage is it consumes more power than usual.

Connectivity and Storage

On analysing Wireless connectivity, Pi 4 has a built-in Bluetooth 5.0 and dual-band WiFi 802.11ac. The built-in WiFi can reach the speed up to 90Mbps, which is more significant for all Broadband internet users. The Gigabit Ethernet port has been upgraded in Raspberry Pi4 and reaches up to 850MBps where the Pi 3 limit was around 300Mbps. It is very useful for transferring large files over the home network.
