iPhone 17's A19 Chip Becomes World's Fastest Single-Core CPU

Apple's A19 chip for the iPhone 17 has claimed the top spot as the world's fastest single-core CPU in PassMark benchmarks, according to Tom's Hardware.

Record-Breaking Performance

The A19 achieved an impressive 5,149 points in single-thread testing, surpassing major competitors:

  • A19 Pro: 5,088 points
  • M3 Ultra (28-core): 5,140 points
  • M3 Ultra (32-core): 5,106 points
  • Intel Core Ultra 9 285K: 5,095 points
  • AMD EPYC 4585PX: 4,797 points

Remarkable Efficiency Advantage

What makes this achievement truly exceptional is the power consumption:

  • A19: ~4W with passive cooling
  • Intel Core Ultra 9 285K: 44W with active cooling
  • AMD EPYC 4585PX: 56W with active cooling

The A19 delivers world-leading performance while using approximately 11x less power than desktop competitors, all without requiring active cooling systems.

This breakthrough demonstrates Apple's continued dominance in mobile chip efficiency and performance optimization.
