Fake News. Apple MAC with AMD CPU.

[Geek-9pm]

Not true.
See here:
The thinking is that Apple would commission a semi-custom processor for use in Apple's Macs -- essentially an Apple-defined product that incorporates a substantial amount of AMD's intellectual property (e.g. processor cores, graphics processors, and so on). Here's why that's highly unlikely. Apple wants complete control

On April 2, Bloomberg reported that Apple (NASDAQ:AAPL) intends to eventually transition its Mac computers away from Intel

Don't hold your breath.

The rumour that Apple may use AMD processors is based on information from data-mining of macOS Catalina 10.15.4 in a Beta release that was available last wednesday. (Feb 5th). It was found that the new Beta had a number of AMD Processor Codenames as well as codenames for a few other unreleased AMD processor products, which were not present in previous releases. Thus the rumour related to the possible availability of AMD processors, which seems reasonable to me as a likely reason such AMD-related code-names are present in the codebase.

The link you provided which you seem to feel debunks the rumour is from April of 2018, And only counters a much weaker rumour from that time frame.
