As others have said, core is not a well defined term at all in computer architecture. Is a core something that has its own program counter? Does it need its own floating point unit to count as a core? What about cores that only do a few ops? Are the cores even all the same, or do they have access to the same resources? For example, a few older Nvidia GPUS have some portion of their cores that have only a single crossbar port, and so perform much worse. The M1 gpu core could very well be equivalent or better than 16 tensor soc cores internally.
