The information unearthed by the iOS 11 GM continues to leak, with the latest data suggesting that Apple’s “A11 Fusion” processor has a total of six cores.

The processor expected to be in the iPhone X contains a mix of 4 intensive processing cores and two high-efficiency cores. Unearthed by Steve Troughton-Smith on Sunday, the iOS 11 leak from the end of the week reveals CPUs labeled 0 through 5.

Without expanding on further delving, the developer claims that four are high-powered “Mistral” cores, with two “Monsoon” ones supplementing the four for lesser computational needs.

For comparison. the A10 Fusion processor in the iPhone 7 and iPhone 7 Plus has a pair of high-performance cores and a pair of high-efficiency cores. The A10X in the iPad Pro refresh from WWDC has three high performance “Hurricane” cores and three high-efficiency “Zephyr” cores.

All of this will be made a lot clearer at Apple’s event on Tuesday, where the company is expected to announce three new iPhones, a new LTE-equipped Apple Watch, and a new 4K Apple TV.
