Apple's iPhone 17 chip becomes the fastest single-core CPU in the world on PassMark, beating PC chips and Apple's own M3 Ultra — passively-cooled A19 CPU catapults past power-hungry competitors

Apple's A19 chip in the iPhone 17 has surpassed all other CPUs in single-core performance on PassMark, even outperforming desktop chips like Intel's Core Ultra 9 285K and AMD's EPYC 4585PX. The A19 achieved this while consuming significantly less power and being passively cooled, showcasing its efficiency. However, in multi-threaded performance, the A19 falls short due to its fewer cores compared to other CPUs. Despite its limitations, the A19's performance in single-core tasks is remarkable, making it the fastest CPU available in this specific benchmark.
