iPhone Duo performance benchmarks reveal A20 Pro power

Early Geekbench 7 performance tests for the iPhone Duo, also referred to as the iPhone 19.4, indicate that its A20 Pro chip delivers power comparable to the iPhone 18 Pro. The device achieved a single-core score of approximately 3,986 and a multi-core score of 11,067.

While the performance is largely on par with the iPhone 18 Pro, some reports suggest the Duo may experience slightly lower speeds or more frequent thermal throttling due to its thinner, foldable design. The iPhone 18 Pro utilizes a larger and more efficient vapor chamber for heat dissipation, whereas the Duo's profile may limit cooling capabilities. Despite these technical nuances, the performance difference is expected to be negligible during daily usage. The device is also confirmed to feature 12GB of RAM.
