The Raspberry Pi 4 is a machine made to solve precise tasks. These types of DIY devices are great for retro gaming, robotics, etc. However, the Raspberry Pi 4 still lacks some necessary power to completely replace the personal computer.
The first step in understanding how powerful this device can be is to check the board's underlying specs. Below you will find the specs of the Raspberry Pi 4 so you can have a good idea bout how strong this device is:
CPU Quad Core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
2, 4, or 8GB LPDDR4–3200 SDRAM memory
Wi-Fi 2.4/5.0 GHz, Bluetooth 5.0, BLE
Gigabit Ethernet port
2 USB 3.0 ports; 2 USB 2.0 ports
Support for two monitors, micro-HDMI connectors (up to 4kp60 resolution)
Support of H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
