Intel 64 is a 64-bit computing architecture developed by Intel. It extends the capabilities of the earlier 32-bit x86 architecture, allowing for larger amounts of memory to be addressed and improved performance for applications that require significant processing power. This architecture supports a wide range of operating systems and software, enabling users to run more complex applications efficiently. Intel 64 is commonly found in modern Intel processors, making it a standard choice for personal computers, servers, and workstations.
