Apple’s iPhone 15 series is expected to be introduced in September. Although it’s been about a month since the phone was announced, some important details about the iPhone 15 Pro’s processor, called A17 Bionic, have leaked to the internet.
According to the leaker URedditor, the A17 Bionic will have 6 CPUs and 6 GPU cores running at 3.7 GHz. That’s slightly higher than the A16’s 6-core CPU and 5-core GPU. The A17 is also said to support 6GB of LPDDR5 DRAM, which is the same amount as the A16.
In February, market research firm TrendForce said that all 2023 iPhone models will have 8GB of RAM. However, the latest leak suggests that the iPhone 15 Pro will have 6GB of RAM just like the iPhone 14 Pro.
The more significant upgrade will likely come from the A17, which is built on TSMC’s new 3nm process. The A16 used a 4nm process, so shrinking to 3nm should improve efficiency. Apple analyst Ming-Chi Kuo recently stated that the 3nm process will reduce power consumption by up to 35%.

According to the leaked specs, the A17 looks like a gradual upgrade over the A16, with reasonable performance and efficiency gains expected from the 3nm process.
…And the A18 Bionic
On the other hand, there are said to be more significant changes for 2024 and beyond. The A18 chip in 2024 could be the first to use TSMC’s next-generation 2nm process. Apple is also designing its own modem chips to replace Qualcomm’s.
Also, a leak last week showed that the iPhone 15 Pro and Pro Max could feature a new 2TB storage tier. This claim was repeated on Weibo and it was added that Apple could increase the basic capacity from 128GB to 256GB in Pro models.
As with all leaks, it’s not possible to come to a firm conclusion until Apple confirms them.
