The Raspberry Pi 4 Model B is a significant upgrade in the Raspberry Pi family of single-board computers. It offers substantial improvements in processing power, multimedia capabilities, memory, and connectivity while maintaining backward compatibility with previous models and similar power consumption.

The Raspberry Pi 4 Model B features a high-performance 64-bit quad-core Broadcom BCM2711 processor, which operates at 1.5GHz, providing a substantial increase in performance compared to its predecessor, the Raspberry Pi 3 Model B+ . This CPU is based on the ARM Cortex-A72 architecture, which is known for its balance of performance and power efficiency.

One of the most notable enhancements is the support for up to 8GB of LPDDR4 SDRAM, with options for 1GB, 2GB, 4GB, or 8GB depending on the model . This allows for more robust multitasking and the ability to handle memory-intensive applications with ease.

The Model B offers dual-display support through two micro-HDMI ports, enabling resolutions up to 4Kp60. This feature is particularly useful for applications that require high-resolution displays, such as media centers or gaming consoles.

For connectivity, the Raspberry Pi 4 Model B includes dual-band 2.4GHz and 5.0GHz wireless LAN, Bluetooth 5.0, and Gigabit Ethernet. This array of connectivity options ensures that the device can be integrated into various networks and used in different scenarios, from IoT projects to media streaming.
