Raspberry Pi 400 (Keyboard Computer/Broadcom BCM2711/Quad-Core Cortex-A72 1.8GHz/4GB LPDDR4) Review
The Raspberry Pi 400 packs a full Raspberry Pi 4 into a keyboard enclosure, predating the newer Raspberry Pi 500 already on this site and remaining in production as a lower-cost keyboard-computer option built on older, cheaper silicon.
Launched as a $70 desktop computer, the Pi 400 established the keyboard-computer form factor that the newer Raspberry Pi 500 later refined with faster silicon, giving budget buyers an entry point that predates and undercuts the 500's pricing.
The Original Keyboard Pi
Launched as a $70 desktop computer, the Pi 400 established the keyboard-computer form factor that the newer Raspberry Pi 500 later refined with faster silicon, giving budget buyers an entry point that predates and undercuts the 500's pricing.
Pi 4-Class Performance in a Keyboard
A quad-core Cortex-A72 at 1.8GHz (slightly overclocked versus the standalone Pi 4 board) delivers capable but dated performance next to the Pi 500's newer Cortex-A76 cores, positioning the 400 as the budget choice for buyers who don't need the latest silicon.
Comparison to Alternatives
Against the Raspberry Pi 500 already on this site, the Pi 400 uses older BCM2711 silicon at a lower price, appealing to education and budget buyers who don't need the 500's performance headroom. Against the Raspberry Pi 5 already on this site, the Pi 400 trails significantly in raw performance while keeping the same convenient keyboard form factor at a lower cost.
