The Raspberry Pi 400 Linux mini PC can now also be ordered with a German keyboard layout, but this version is currently out of stock at some retailers. Supplies are expected to arrive there in mid-November.
Andere Chip-Version
Also, the Raspberry Pi Foundation uses a “C0” version of the Broadcom BCM2711 chip in the recently introduced Raspberry Pi 400, while the “B0” version is found on the Raspberry Pi 4. The factory clock of the BCM2711 C0 in the Raspi 400 is 1, 8 GHz, while it is 1.5 GHz in the Raspi 4 with BCM2711 B0. However, the chip can be overclocked, which usually only makes sense with improved cooling, because otherwise it quickly slows down under load.
When using the Raspberry Pi 400 in practice, there is no significant performance increase over the Raspi 4 due to the 20% higher clock rate; However, the BCM2711 of the Raspi 400 does not slow down thanks to the good passive cooling, as already mentioned in the introduction phase.
Data sheet BCM2711
Der Broadcom BCM2711 in version C0 (2711ZPKFSB06C0T)
In mid-October, the Raspberry Pi Foundation published a datasheet for software control of the peripheral connections of the Broadcom BCM2711: BCM2711 ARM Peripherals. However, it does not contain any information on production variants. Version C0 has type code 2711ZPKFSB06C0T, version B0 2711ZPKFSB06B0T.
WiFi transmission speed
The Raspberry Pi 400 WLAN module RPI-RM0 with Broadcom / Cypress CYW43455.
During the measurements in the c’t laboratory, the integrated SDIO WLAN adapter (RPi-RM0 with Cypress CYW43455, FCC ID 2ABCB-RPIRM0) transmitted an average between 30 and 90 Mbit / s: the latter near the router, the first at a distance of 20 meters from that. Transmission speeds in the 5 GHz band are slightly lower than in 2.4 GHz.
