Which CPU is used in my Raspberry Pi 4?

Hy there. I have a little issue on my Pi. I take a look at my system config with "neofetch" in terminal and it means that I have the BCM2853 CPU.

This BCM2835 CPU is used at RaspberryPi 2 board as you can read at https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2835/README.md

Does someone knows why mate means there is a BCM2835 instead of the BCM2711??

Thanks

Hi
Probably this:

Quote: Why does cpuinfo report I have a BCM2835?

The upstream Linux kernel developers had decided that all models of Raspberry Pi return bcm2835 as the SoC name. At Raspberry Pi we like to use as much upstream kernel code as possible, as it makes software maintenance much easier, so we use this code. Unfortunately it means that cat /proc/cpuinfo is inaccurate for the Raspberry Pi 2, Raspberry Pi 3 and Raspberry Pi 4, which use the bcm2836/bcm2837, bcm2837 and bcm2711 respectively. You can use cat /proc/device-tree/model to get an accurate description of the SoC on your Raspberry Pi model.
