The iPhone Duo offers performance similar to the iPhone 18 Pro, according to an early benchmark shared on Geekbench 7. Both devices use Apple's 2nm A20 Pro chip, with a 6-core CPU and a 7-core GPU.
The benchmarked iPhone Duo (iPhone19,4) runs iOS 27.1 and posted a single-core score of 3986 and a multi-core score of 11067. Those results are in line with multiple benchmarks collected from iPhone 18 Pro and iPhone 18 Pro Max models. The device also lists 11.30GB of memory, which corresponds to 12GB of RAM, and a 6-core CPU with a 4.93GHz base frequency, matching iPhone 18 Pro benchmarks.
Scores vary from test to test, and this result falls short of the top iPhone 18 Pro benchmark scores, but only a single score has been viewed so far. Real-world performance could also differ between the two models due to thermal management, the iPhone Duo's two screens compared with a single screen, and other factors.
Apple says the A20 Pro offers up to 20 percent faster CPU performance than the A19 Pro and up to 40 percent faster GPU performance. GPU speeds were not tested in this benchmark. Pre-orders for the iPhone Duo start October 16, with launch following on October 23.
