The Raspberry Pi Foundationofficially announced the fourth version of its miniature computer. The Raspberry Pi 4 maintains the same form factor and the initial price of $ 35 of its predecessor, but has improved specifications across the board. Now it offers up to 4GB of RAM (four times more than any previous Pi), faster CPUs and GPUs, faster Ethernet, dual-band Wi-Fi, twice as many HDMI outputs and two USB ports 3. the Raspberry Pi 4 is usable as a replacement for the cheap desktop PC if you opt for its more expensive 4GB model. The Tom’s Hardware review notes that the hardware is capable of handling many daily tasks such as browsing the web up to 15 Chromium cards, editing clear images via GIMP and working on documents and spreadsheets with Libre Office. Not surprisingly, the $ 100 miniature PC has its limits. It is said that he is struggling with playing full-screen videos from YouTube, for example, even if you lower the resolution to 480p.
Here is a complete list of Raspberry Pi 4 improvements compared to its predecessor, the Raspberry Pi 3 B +:
- Broadcom quad-core 1.5GHz CPU, up to 1.4GHz in the previous model.
- VideoCore VI GPU at 500 MHz, up to 400 MHz previously.
- A USB Type-C port for power supply instead of Micro USB.
- Two Micro HDMI ports that can power two 4K monitors at 30 fps or a single 4K monitor at 60 fps next to a 1080p display.
- Two USB 3 ports and two USB 2 ports, compared to four USB 2 ports.
- A Gigabit Ethernet port that is no longer limited by a USB interface.
- Bluetooth 5.0 instead of 4.1.
- Wi-Fi 802.11ac dual-band.
- A microSD memory card with a theoretical maximum transfer rate of 50 Mbps, from 25 Mbps.
- A 40-pin GPIO connector with support for three other interfaces; I2C, SPI and UART.
The Raspberry Pi 4 is available starting today with 1 GB, 2 GB or 4 GB of RAM for $ 35, $ 45 and $ 55.
