The reason 8gen3 is not 3nm is that 8gen3 is Intel's process code name, not the actual nanoscale. Process code is used to describe the chip manufacturing process, usually based on some technical parameters and process characteristics to name. For example, the 8gen3 represents the third process version of Intel's 8th-generation processor, which uses a 14nm process. 3nm refers to the nanoscale size of the process, which is an actual scale parameter. At present, the most advanced process in the global chip manufacturing industry is only about 7nm, and the 3nm process is still in the research and development stage, and there may be enterprises to achieve it in the future. Therefore, 8gen3 cannot be called 3nm.
The reason 8gen3 is not 3nm is because. 8gen3" The name refers to Intel's eighth generation Core processors, not the process technology. The number 8 represents the algebra of the processor family. The 3nm refers to the process technology, indicating the minimum line width size for manufacturing chips. At present, Intel's core processor process technology has not reached 3nm, and its latest process technology is 10nm, that is, the tenth generation of core processors. So while the 8gen3 represents Intel's eighth generation of core processors, it doesn't mean its process technology reaches 3nm.
