Raspberry Pi 4 is powered by a Broadcom BCM2711 quad-core Cortex-A72 64-bit unit running at 1.5GHz.
Like older Raspberry Pi devices, the new Pi 4 is a compact computer with nearly everything you need on a single board. It features VideoCore VI graphics, and 4K 60fps video output (or two 4K 30fps outputs) plus HEVC video decode.
A case for the Raspberry Pi 4 costs $5.
What hasn't changed over the years, though, is a major drawback of the design: A communication infrastructure that sees the system-on-chip (SoC) of every Raspberry Pi communicating with external devices over a single 480Mb/s USB 2.0 channel.
"The vision behind Raspberry Pi 4 is to make a rich multimedia PC experience accessible to everyone", Upton said.
Other specifications of the Raspberry Pi 4 Model B include a Gigabit Ethernet port with PoE (power over ethernet), dual-band Wi-Fi 802.11ac, Bluetooth 5, two USB 2.0 and two USB 3.0 ports, and dual 4K monitor support.
There's also the matter of the move of the ethernet port. While the 2GB and 4GB RAM models are no doubt more expensive compared to previous Raspberry Pi models, the significant improvement in performance does help justify the premium.
Peripherals can be attached one of 4 USB ports - two each of USB 3.0 and USB 2.0.
New RAM options have also been provided as you can now choose from 1GB, 2GB and the highest RAM option available now is 4GB LPDDR4-2400 SDRAM, which is a massive upgrade as previous models were limited to just 1GB of RAM. Each upgrade adds $10 to the $25 starting price. The Raspberry Pi foundation has also made affordable USB Type-C power supplies, cables, and adapters available through its global distributors to help reduce overall development costs. $55 gets you the fully-loaded model with 4GB.
The credit card-sized computer is created to be highly customisable with an appeal to computer hobbyists, but can also be bought in a bundle with a mouse, keyboard, SD card, power supply, cables and case for the first time to help recreate the experience of a desktop computer. The Raspberry Pi 4 is available for purchase today from multiple retailers.
