iPhone 18 Pro and Pro Max Benchmarks Reveal Speed of A20 Pro Chip

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.

CUPERTINO, CALIFORNIA — Apple today introduced A20 Pro, the most Pro chip ever in an iPhone, delivering roughly 21%–23% faster single-core and 27%–28% faster multi-core performance than A19 Pro.

Apps now open so fast, they may launch before you tap the icon. And Siri is now so advanced, it can fail to understand you before you’ve even asked the question.

Because with great power that most people absolutely do not need comes great responsibility: using all that silicon to take super-high-resolution, AI-enhanced pictures of your cat and 8K videos only a cat lady could love, only for Instagram and Reddit to compress them into something that looks like it was shot through a screen door.

A20 Pro. Did we mention it is Our most Pro chip ever in our most Pro phone ever? Your apps are already open. Siri is already confused.

I wonder how much of this is due to AI help with designing the systems. Hopefully none of it. That said, I wonder.
Why "hopefully none of it" and what sort of AI? We've been using AI for 50+ years, of course it's involved in running software simulations for chip architecture, of course they use machine learning to test as many variations as possible.

If you specifically mean "LLMs" as "AI" then I doubt they'd have much help with chip design except for writing tests quicker than a human could so they could run more and varied test scenarios, which is a good thing.

Is it worth to upgrade if I have the 17 pro max ?
For 99.8%+ of use cases: no.

This is one of the aspects of an iPhone that rarely seems obvious. I never think 'wow this iPhone is faster than my old one', because it never feels that way. Then again I have never played games on any of the iPhones I have owned, so perhaps it is more obvious in that regard.
I went from an iPhone 11 to a 15 Pro Max in my last upgrade. In over two years it has never seemed faster at anything than the 11. It was my one disappointment with upgrade.
