Early benchmark results for the A20 Pro chip in the iPhone 18 Pro and iPhone 18 Pro Max appeared early this morning in the Geekbench 7 database, offering us a first look at the new models' CPU and graphics performance ahead of the devices reaching customers.
Based on these early results – which are unconfirmed – the A20 Pro chip across the Pro models appears to deliver around 21% to 23% faster performance in single-core and 27% to 28% faster performance in multi-core than the A19 Pro chip in the iPhone 17 Pro. It's a pretty impressive jump.
The iPhone 18 Pro result lists a single-core score of 4,719 and a multi-core score of 12,677, while an iPhone 18 Pro Max entry delivers similar results, scoring 4,725 and 12,575, respectively. Both identify a six-core CPU running at approximately 4.93 GHz.
There are similarly formidable gains on the graphics side for the A20 Pro. Based on early Metal scores in the Geekbench 6 database (also unconfirmed) the full 7-core GPU variant of the chip in the iPhone 18 Pro models is around 38% to 40% faster than the A19 Pro's 6-core GPU.
The graphics results broadly match Apple's claim in its iPhone 18 Pro press release and product page that the A20 Pro offers up to 20% faster CPU performance compared to the A19 Pro chip in the iPhone 17 Pro models, while the A20 Pro's new seven-core GPU is up to 40% faster than the A19 Pro.
Built using a 2-nanometer process, the chip also features a six-core CPU with integrated Neural Accelerators and 50% more memory bandwidth than its predecessor. Apple also says the new chip packaging and redesigned vapor chamber enable up to 40% better sustained performance than the previous generation.
Note that these one-off benchmarks, which have yet to be independently verified, don't tell us how the devices will perform during prolonged gaming or other demanding workloads – benchmark results and real-world performance are never totally analogous.
