The Raspberry Pi Foundation has announced the fourth version of its miniature budget computer. The Raspberry Pi 4 retains the same form factor and $ 35 starting price of its predecessor, but that is the case improved specifications across the board. It now comes with up to 4 GB of RAM (four times that of a previous Pi), a faster CPU and GPU, faster Ethernet, dual-band wifi, twice the amount of HDMI outputs and two USB 3 ports.
These upgrades mean that the Raspberry Pi 4 can be used as a budget desktop PC replacement if you opt for its most expensive 4 GB model. Tom & # 39; s Hardware & # 39; s rating notes that the hardware is able to handle many daily tasks, such as surfing the web with up to 15 Chromium tabs, light image editing with GIMP and document and spreadsheet work with Libre Office. Of course the sub- $ 100 miniature PC has its limits. Reportedly, it is struggling to play full screen video & # 39; s from YouTube, even if you lower the resolution to 480p.
Here is a full list of the improvements to the Raspberry Pi 3 B's compared to its predecessor, the Raspberry Pi 3 B +:
- Quad-core 1.5 GHz Broadcom CPU, an increase of 1.4 GHz in the previous model.
- 500 MHz VideoCore VI GPU, previously higher than 400 MHz.
- A USB Type-C port for power supply, instead of Micro USB.
- Two micro HDMI ports that can control two 4K monitors with 30 fps, or a single 4K monitor at 60 fps in addition to a 1080p screen.
- Two USB 3 ports and two USB 2 ports, up to four USB 2 ports.
- A Gigabit Ethernet port that is no longer smothered by a USB interface.
- Bluetooth 5.0 instead of 4.1.
- Dual-band 802.11ac wifi.
- A microSD storage card with a theoretical maximum transfer speed of 50 Mbps, an increase of 25 Mbps.
- A 40-pin GPIO connector with support for three more interfaces; I2C, SPI and UART.
The Raspberry Pi 4 is available from today with 1 GB, 2 GB or 4 GB RAM for $ 35, $ 45 and $ 55 respectively.
