The difference between M1 chip processor and Intel is that the architecture is different, M1 chip processor is a self-developed chip launched by Apple based on ARM architecture, and its performance is considered very strong, and even can be compared to Intel's i9 processor.
The integrated graphics card in the M1 offers 8 cores (7 cores for the entry-level MacBookAir) and 2.6teraflops of peak performance, in addition to the SoC integrating a fast 16-core neural engine with 16TOPS (for AI hardware acceleration) of peak performance, secure areas (for example for encryption), a unified memory architecture, and a high level of performance.
