Well yes, but the statement that Intel always copies AMD is then incorrect, as they copy each other
But as for history:
1975 AMD introduced a
reverse-engineered clone of the Intel 8080 microprocessor
1982, AMD signed a contract with Intel, becoming a licensed
second-source manufacturer of 8086 and 8088 processors
1991, AMD released the Am386, its
clone of the Intel 386 processor
2006 AMD received subpoenas from the Justice Department regarding possible antitrust violations in the graphics card industry, including the act of fixing prices (Intel was already charged in the late '80s and '99, so they were again behind)
Kinda of bad though, You buy a license from a company to make their product.. and then sue them all the time because they are better than you, and copied you as well
