Apple's latest generation of iPhones is equipped with its A19 chips — the standard A19 on iPhone 17 and the A19 Pro on iPhone 17 Air and Pros — which represent the best the company has to offer, literally. In PassMark's single-threaded benchmark, the A19 produced the best numbers of any chip available, including fully-fledged desktop SKUs. It did that while consuming significantly less power and being passively cooled. At least in this hyper-specific case, Apple's A19 has become the fastest CPU available.
Both the A19 and A19 Pro benchmarked within the margin of error of each other; however, officially, it was the regular A19 that posted 5,149 points to claim the single-thread performance crown. The A19 Pro scored 5,088 points, which makes sense considering both chips share the same cores, just differing amounts of them. The A19 beats heavy hitters like Apple's own desktop-class M3 Ultra (both 28- and 32-core variants), Intel's Core Ultra 9 285K, and even the EPYC 4585PX from AMD — all of which would be actively cooled.
