iPhone Duo benchmark reveals performance close to iPhone 18 Pro
Apple‘s first foldable smartphone, the iPhone Duo, has appeared in an early Geekbench 7 test, showing processing performance comparable to the iPhone 18 Pro and iPhone 18 Pro Max ahead of its release on 23 October.
The device achieved a single-core score of 3,986 and a multi-core score of 11,067, according to a benchmark reported by MacRumors on 14 October.
Although the results fall below some of the highest scores recorded by the iPhone 18 Pro models, they remain within the range of their reported performance. The test provides an early indication that Apple’s foldable will offer processing capabilities similar to its conventional flagship smartphones.
The benchmark identifies the device as iPhone19,4, running iOS 27.1. It also lists 11.30GB of usable memory, confirming that the iPhone Duo comes equipped with 12GB of RAM.
What powers Apple’s first foldable iPhone?
The iPhone Duo uses the same A20 Pro processor found in the iPhone 18 Pro and Pro Max.
Manufactured using a 2-nanometre process, the chip features a six-core CPU and a seven-core GPU. The benchmark lists a CPU base frequency of 4.93GHz, matching the configuration recorded in earlier iPhone 18 Pro tests.
According to Apple, the A20 Pro offers up to 20% faster CPU performance and 40% faster GPU performance compared with the previous-generation A19 Pro.
However, the latest benchmark only measures CPU performance, leaving the Duo’s graphics capabilities untested.
Despite sharing the same processor, the foldable could perform differently from the iPhone 18 Pro during prolonged use. Its dual-display design and thermal management system may affect sustained performance, particularly during demanding activities such as gaming and video editing.
