Raspberry Pi 5 8GB

More than twice as fast and infinitely smoother
Raspberry Pi 5 features the Broadcom BCM2712 quad-core Arm Cortex A76 processor @ 2.4GH z, making it up to three times faster than the previous generation. With RAM variants up to 8GB, this is the fastest, smoothest Raspberry Pi experience yet.
RP1
Raspberry Pi 5 is built using the RP1 I/O controller, a package containing silicon designed in-house at Raspberry Pi.

USB 3 has more total bandwidth, for much faster transfer speeds.

Camera and DSI display connectors are interchangeable, so you can have one of each, or two the same.
All aboard the PCI express
This addition to Raspberry Pi allows you to connect an M. 2 SSD to your Raspberry Pi, giving you speedy data transfer and super-fast boot.
