At yesterday's September Fall Event, Apple officially unveils iPhone 8, 8 Plus, and iPhone X, they are equipped with a six-core A11 Bionic Chip, which Apple calls it as the world's most powerful, most intelligent processor, the chip brings some major improvements over the A10 chip in the iPhone 7. The processor features two performance cores and four efficiency cores.
Well-known Apple blog MacRumors spoke to Geekbench's John Poole, saying he believes the A11 benchmarks are real. Poole believes A11’s two high performance cores are probably clocked at 2.5GHz, up from the 2.34GHz CPU cores in the A10 Fusion chip. Just imagine, the 24MHz reading is an anomaly.
In 12 Geekbench scans, the A11 chip saw an average single-core score of 4169, and an average multi-core score of 9836. Some individual scores were much higher, though, with single-core scores and multi-core scores of 4274 and 10438. By comparison the latest 10.5-inch iPad Pro powered by the A10X Fusion chip saw single and multi-core scores of about 3,887 and 9,210.
As for highest-end 13-inch 2017 MacBook Pro with Intel’s 3.5GHz dual-core chip, it has a single-core score of 4592 and a multi-core score of 9602, suggesting the A11 outperforms it on multi-core tasks and comes close on single-core tasks.
As a result, the iPhone X and iPhone 8 Plus will offer significantly better performance than the iPhone 7. The iPhone 7 which featured with A10 Fusion has an average single-core Geekbench score of 3327 and a multi-core score of 5542.
As mentioned by Apple, the performance (For task such as play games) cores in the A11 chip are 25 percent faster than the A10 chip on iPhone 7 and 7 Plus, while the efficiency cores (For small tasks like listening music) are 70 percent faster than the A10 chip. The A11 chip is better at multi-threaded tasks because a second-generation performance controller is able to harness all six of the cores simultaneously.
