CPU development cannot avoid architectural standards.
For a long time, CPUs have been monopolized by Intel and AMD. CPUs are also recognized by the industry as the most difficult to develop, because as long as you develop CPUs, you cannot avoid architectural standards and various patents. There is only one mainstream standard in the world, X86, and its patent rights are in the hands of Intel. Even the famous AMD all uses this standard. As long as you use this standard, the CPU you make can be compatible with other mainstream hardware, Windows operating systems, various software, etc. If Intel doesn't authorize it, you won't be able to do it, and Intel is constantly making progress driven by Moore's Law, so it has the capital to look down on other competitors. If you use my standards, your life is in my hands, especially if you don't believe that China can make a CPU.
