    Newest Raspberry Pi 5 Model B 1GB 2GB 4GB 8GB RAM Full Desktop Starter Kit Raspberry Pi 5 Module 5b + Pi5 4G 8G Raspberry Pi 5

    Product introduction

    The Raspberry Pi 5 is powered by a 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz, providing 2-3 times better CPU performance compared to the Raspberry Pi 4. In addition, the graphics performance of the 800MHz Video Core VII GPU has been significantly improved; Dual 4Kp60 display output via HDMI; As well as advanced camera support from the redesigned Raspberry PI image signal processor, it provides users with a smooth desktop experience and opens the door to new applications for industrial customers.

    Raspberry PI introduces Raspberry PI chips on flagship products for the first time! The RP1 “southbridge” provides most of the I/O capabilities for the Raspberry PI 5 and makes significant changes in peripheral performance and functionality. More than double the total USB bandwidth for faster transfers to external UAS drives and other high-speed peripherals; The dedicated dual-channel 1Gbps MIPI camera and display interface on earlier models has been replaced by a pair of quad-channel 1.5GbpsMIPI transceivers, tripling the total bandwidth and supporting any combination of up to two cameras or displays; SD card’s peak performance is doubled by supporting SDR104 high-speed mode; For the first time, the platform exposes a single-wire PCI Express2.0 interface to support high-bandwidth peripherals.
