Today, Raspberry Pi is introducing a new version of its popular line of single-board computer. The Raspberry Pi 4 Model B is the fastest Raspberry Pi ever, with the company promising "desktop performance comparable to entry-level x86 PC systems."
The new model is built around a Broadcom BCM2711 SoC, which, with four 1.5GHz Cortex A72 CPU cores, should be a big upgrade over the quad core Cortex A53 CPU in the Raspberry Pi 3. The RAM options are the even bigger upgrade though, with options for 1GB, 2GB, and even 4GB of DDR4. The Pi 3 was limited to 1GB of RAM, which really stung for desktop-class use cases.
There has been some upgrades and tweaks to the Pi 4 I/O, too. The Gigabit Ethernet returns, as do the four USB ports, but two of them get an upgrade to USB 3.0. Power is now supplied via a USB-C port, instead of the aging Micro USB of the Pi 3. The headphone jack returns, too, and it's still a four-pole solution providing audio and comRead More – Source
