The new Apple chip has more cores, so faster performance doesn't necessarily mean faster single-core performance. Faster on a parallel benchmark doesn't necessarily translate into faster performance for most real-world scenarios. That is all. That being said, I do believe Apple has very competent chip designers.
Apple claims the M1 to be the fastest CPU in the world. Given our data on the A14, beating all of Intel’s designs, and just falling short of AMD’s newest Zen3 chips – a higher clocked Firestorm above 3GHz, the 50% larger L2 cache, and an unleashed TDP, we can certainly believe Apple and the M1 to be able to achieve that claim.
