Raspberry Pi 4 Model B 2GB is a miniature single-board computer that can fully replace a desktop PC running Linux. The platform is suitable not only for web surfing and application development but can also serve as the "brain" for a robot or smart home, a media center, a node in a distributed computing system, or an industrial controller.

Raspberry Pi 4 utilizes the Broadcom BCM2711 system-on-a-chip. The chip features a 4-core 64-bit Cortex-A72 (ARM v8) processor clocked at 1.5GHz and a VideoCore VI GPU with a frequency of 500MHz. According to the manufacturer, the system on the new architecture is 50% faster than previous generations of Raspberry Pi, and the RAM has been increased to 8GB.

Key innovations of the new version compared to the Raspberry Pi 3 Model B+ include:

Support for 4K resolution at 60Hz (HDMI 2.0)
Ability to work with two monitors simultaneously
Hardware acceleration for H.265 video streaming
Presence of USB 3.0 ports
Gigabit Ethernet controller with full-speed capability
Increased RAM capacity up to 8GB
