iPhone 18 Pro and iPhone Ultra will be unveiled next month with a new A20 Pro chip, and this weekend a reputable leaker shared performance gains to expect per supply chain sources.

Apple’s big September event will introduce its latest in silicon advancements: the A20 Pro chip.

A20 Pro will be the first Apple chip built on TSMC’s 2nm process. It’s also rumored to adopt a new Wafer-Level Multi-Chip Module (WMCM) packaging method.

Because of these innovations, we’ve been expecting larger than usual improvements with this year’s chip.

Weibo leaker Fixed Focus Digital posted this weekend that, based on supply chain sources, A20 Pro will offer the following upgrades compared to A19 Pro:

• 18% faster performance
• 30% better power efficiency

The finer details will no doubt be more nuanced when Apple shares the full story next month. For example, the company typically breaks down gains individually across CPU, GPU, and Neural Engine.

But if these numbers prove accurate, it’s a really solid boost coming. Efficiency gains should lead to better battery life, while still delivering better than ever performance.

Combined with iOS 27’s own speed gains, the iPhone 18 Pro and iPhone Ultra are shaping up to be exciting updates in the performance department.

What do you think of the alleged gains in A20 Pro? Let us know in the comments.
