This morning, the Raspberry Pi Foundation eradicated its next-generation hobby project computer, the Raspberry Pi 4. The much-anticipated update of the Raspberry Pi line, which luckily appears to be ahead of schedule in SoC development, offers a significant upgrade for the family thanks to the new 28nm Broadcom SoC, which includes a more powerful quad-core Arm Cortex-A72 CPU cluster contains. The single-board computer is available now and prices start at $ 35, like its predecessors.
For a long time, the Raspberry Pi family was a hobbyist, manufacturer, and anyone looking for a project board or simple computer. The last full update was in 2016, when the Foundation released the Raspberry Pi 3. Over the last three years, the technology landscape has changed a bit, as has the underlying hardware of the Pi. The new Pi is still based on Broadcom SoCs and incorporates Broadcom's BCM271

I / O has also received a much needed upgrade for the latest Pi. The new SoC offers USB 3 support, giving the platform access to SuperSpeed USB data rates for the first time. The HDMI support was similarly raised to 2.0 (ie 4K output support). Fittingly, the board can now decode H.264 and H.265 video (another premiere) at resolutions up to 4K. Network performance has also been enhanced by the addition of a Gigabit Ethernet full-speed port, and the connection to the 802.11ac radio supports Bluetooth 5.0.
In total, the Foundation sells 3 different versions of the Raspberry Pi 4. depending on the memory configuration. The $ 35 model comes with 1GB of LPDDR4, while 2GB and 4GB models are available for $ 45 and $ 55, respectively. Which is a clear shot in the arm for the board with the latter two models, since they can now play with two to four times the memory.
In the meantime, our sister site Tom's Hardware has an early retrospect and confirmed much of what you would expect from the Raspberry Pi 4 based on the specifications. CPU, memory and memory performance have improved significantly over previous models, although power consumption has increased slightly.
