The Raspberry Pi foundation just released an awesome new product, something that they’ve never done before.
This is known as the Raspberry Pi 400 it’s an all-in-one pc, an all-in-one personal computer that’s powered by the same CPU that’s used in the raspberry pi 4.
The All new Raspberry Pi 400 is a complete Raspberry Pi 4 model B built into a keyboard form-factor.
for the Broadcom BCM 2711 SoC there’s a new revision to this chip it’s called a new stepping , so this new chip can actually control the CPU a little bit better it gets a little bit better thermals for the same performance so i think that’s how they overclocked it a little bit from what was in the Pi 4.
The heat sink is massive and it can handle a lot of thermal load and that chip is newer and the chip can handle the higher speeds without getting as hot . Heat sink is helping to dissipate that heat a lot.
