Finding schematics for the interior of modern processors, particularly those from the 32nm node and earlier, is challenging due to proprietary concerns. Major manufacturers like Intel are unlikely to release detailed schematics, similar to how Coca-Cola protects its formula. The complexity of modern chips, which can contain billions of transistors, makes traditional schematics impractical. A recommended starting point for research is the U.S. Patent Office, where historical patents, such as the one for the 8080 CPU, can provide insights into earlier designs.
