Recommend СPU "open source processor" comparable in performance to the n100!
What's an "open source chip" ?
For this chip, all source code must be open source.
Then it's actually not the chip that's supposed to be open source, but the software it uses ?

Yes, exactly!
Technically there's (or used to be) a Minix instance inside the intel CPUs, acting like a 1st stage loader, it's probably very much (C).

What's wrong with the N100?
The problem with x86_64 is the UEFI and the ManagementEngine. With Protectli there are corresponding Coreboot variants that help. However, the devices also cost more but you support the development of CoreBoot. There is also LibreBoot... (but I am not aware of any devices that use this).
Intel ME Disable
The Intel Management Engine (ME) is a complete stack on an independent subsystem that allows remote access to a system. In some cases, the ME can run even when the device is powered off. However, there have been multiple vulnerabilities over the years, and security conscious customers have wanted the ability to disable the functionality. Intel ME Disable is a feature which disables the Intel ME. The implementation of coreboot for the Protectli VP4600 and VP2420 has Intel ME disabled by default using the soft-disable method, VP6600 uses HAP method. These methods are documented at this link: https://docs.dasharo.com/osf-trivia-list/me/#soft-disabling-me
Note that if the unit is reflashed with another BIOS, such as AMI, Intel ME will be reenabled and all of the security features mentioned above will be inactive.

What kind of processor RISC-V Nuclei CPU IP Solution?
Аnd also this one: XiangShan open-source 64-bit RISC-V processor to rival Arm Cortex-A76.
These are just projects?

How about you start by checking which CPUs are supported by Linux, instead of name dropping random results from your Google search?

Intel N200 - see https://nl.starlabs.systems/pages/byte
Thanks for the advice! I looked at this list:
List of Linux-supported computer architectures
I didn't find anything else that I needed only Rockchip and MediaTek 
.
Unfortunately this processor N200 is not "open source chip" (price from €417,60).
The link I provided to Starlabs Byte demonstrates that this hardware is supported by Coreboot for an open Source bootloader.
If this is not enough for you I advise you to look at LibreCMC (fork of OpewnWrt) who claim to strip off all firmware binary blobs (ie look at NanoPi R4s)

Thank you, but I am searching СPU “open source chip” comparable to n100!
That phrase is not translating.
Whatever Google translate thinks you mean makes no sense to native English speakers.
I'm not even sure this is OpenWrt related.

Are you a native English speaker?
It is not translating; we've made that clear.
And it is now 18 posts in and no, real, OpenWrt question.

There are very few truly open source processor designs, especially that are actually fab'd and then used in a physical device suitable for running OpenWrt or other linux OS's.
Keeping in mind that this is the OpenWrt forum and the supported devices are typically either purpose built router/network equipment or SBCs or x86, it should be clear that you're not going tofind some esoteric fully-open-sourced design (i.e. the silicon).
@kotamo - Please explain what it is that is driving you to such a specific goal? What are you trying to achieve that cannot be done with a standard supported device? What is your goal?
