It shouldn’t be all that surprising that an SoC powering a fanless MacBook Air is more energy efficient than an Intel 8th-gen Core i7 CPU rated at a TDP of 65 watts, which does need a fan to keep cool. But even as Apple’s own power consumption figures exceed those observed by reviewers, they make Intel look particularly bad when you consider the superior performance of Apple Silicon.
When Apple revealed the first line of M1-powered devices, it made a number of claims about the performance and energy efficiency of these systems when compared to Intel-powered counterparts.
