One more twist on a well-known board.
Both the CPU and the GPU had gained many integers, but the Raspberry Pi 400 format allows to go a little further in the field of power.
Although Many specifications coincide, the Raspberry Pi 400 tightens the nuts a little more on the Broadcom BCM2711B0 CPU, which here has a clock frequency of 1.8 GHz compared to the 1.5 GHz of the conventional RPi 4 Model B.
CPU: 1.8GHz quad-core 64-bit ARM Cortex-A72 CPU
GPU: VideoCore VI graphics, with OpenGL ES 3.x support

HDMI: 2 micro HDMI outputs
Video: 4Kp60 hardware decode of H.265 (HEVC)
1080p60 hardware decode, and 1080p30 hardware encode of H.264 (AVC) video Dual HDMI up to 4K resolution
Audio: only through HDMI there is no jack output
2 × USB 3.0
1 x USB 2.0
Wi-Fi: can include wireless connection in the 2.4GHz and 5GHz IEEE band 802.11b / g / n / ac wireless LAN
Bluetooth 5.0 BLE
Gigabit Ethernet PHY with IEEE 1588
GPIO: 40-pin, with up to 6 × UART, 6 × I2C and 5 × SPI
Power: USB-C at 5Vdc
