The iPhone 15 Pro is rumored to have 8GB RAM.
Apple may choose to increase the RAM in the iPhone 15 Pro to 8GB in order to improve performance and multitasking capabilities.
It's anticipated that the iPhone 15 series will debut next month, maybe on September 12 or 13. As far as we are aware, the non-Pro versions will continue to use the A16 while the Pro variants (iPhone 15 Pro and Pro Max) will solely employ the new Apple A17 Bionic chipset. The iPhone 15 Pro and Pro Max were reportedly still going to include 6GB of RAM, according to a prior insider tip. Possibly from Micron or Samsung, and of the speedier LPDDR5 version, but 6GB is 6GB anyway.
Since the iPhone 12 Pro, the iPhone has only had 6GB of RAM. But owing to end-to-end vertical and horizontal optimization, that has proven to be sufficient. According to a fresh report from the same X (formerly Twitter) user Unknownz21, there may be a possibility to see an iPhone with 8GB this year.
Update: It appears that both 8GB and 6GB RAM configurations for A17 were in testing at one point, currently unclear why or which of these was chosen as final - could be dependent on storage.They’re labeled as follows:POP, COLL + 6GPOP, COLL + 8G

According to rumors, the new A17 Bionic has been tested in both the iPhone 15 Pro and iPhone 15 Pro Max variants with 6GB and 8GB of RAM. The source is unsure of the final RAM capacity that was chosen. However, Apple is possible that higher storage tiers of the iPhone 15 Pro and Pro Max will include 8GB of RAM and maybe offer a modest speed boost.
This is only conjecture at this moment, and based on Apple's past performance, a uniform RAM capacity throughout at least the Pro range seems more plausible. Having said that, linking together RAM and storage quantities has long been common in the Android world, so it would not be completely absurd to think Apple is doing the same.
