Brand new Raspberry Pi 4 supports 4GB of RAM and 4K displays

26.06.2019 | BGR | www.bgr.com

There’s a brand new Raspberry Pi model in town, one that supports up to 4GB of RAM as well as dual 4K display. That’s impressive power from a tiny board that starts at $35, making it a no-brainer purchase. The Raspberry Pi 4 Model B is what you want to be looking for, a device that will bring you “a complete desktop” experience.”

Specs include a 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU that will deliver a 3x performance bump, up to 4GB of LPDDR4 RAM, VideoCore VI graphics with support for OpenGL ES 3.x, two USB 3.0 and two USB 2.0 ports, USB-C, dual-band 802.11ac wireless support, Bluetooth 5, dual 4K monitor support (via micro HDMI connectors), 4Kp60 hardware decode of HEVC video, and Gigabit Ethernet.

For $35, you get the 1GB of RAM version, and it’ll cost you $10 extra each time you double the memory — so you can go up to $55 for a maxed out version of the new board. The new Raspberry Pi 4 case also gets new accessories, like a new case that matches the arrangement of the new ports, as well as a new USB-C power supply, which delivers power of up to 15W. Both of these will cost you an extra $5 on top of the actual board.
