Leaked Benchmarks Show Big Performance Leap for Apple’s A20 Pro in iPhone 18 Pro Line

Early unverified benchmark runs point to large CPU/GPU gains that could mark a meaningful architecture leap for Apple

Overview

  • Apple introduced the iPhone 18 Pro and iPhone 18 Pro Max with the A20 Pro, a 2‑nanometer system on chip Apple describes as a six‑core CPU, seven‑core GPU, 50 percent more memory bandwidth, and a Dual 16‑core Neural Engine.
  • Multiple early Geekbench 7 Browser and shared Geekbench runs report single‑core scores roughly in the high 3,900–4,700 range, multi‑core scores near 10,900–12,700, and Metal GPU scores around 60,000–63,000, which analysts translate to roughly 24–31% CPU and 45–47% GPU generational gains over the prior models.
  • Benchmark metadata from those runs lists a six‑core processor peaking near 4.93GHz, about 11.2GB of usable memory consistent with 12GB installed, and larger L1/L2 cache figures than the A19 Pro.
  • Those figures remain unverified early leaks and may reflect peak conditions or test variability, so publications caution that higher benchmark numbers do not guarantee obvious day‑to‑day speed improvements for typical users.
  • Preorders for the iPhone 18 Pro line opened today with starting prices of $1,199 for the Pro and $1,299 for the Pro Max, and units are scheduled to reach retail on September 18, a launch that could push stronger on‑device gaming, graphics workloads, and AI tasks if sustained performance matches the leaks.
