iPhone Duo full benchmarks — the world's fastest foldable, but how does it stack up to iPhone 18 Pro?

Apple's iPhone Duo has faced significant scrutiny, and proving its superiority as the best foldable phone is crucial. One area where it may excel is performance, thanks to the A20 Pro chip powering the device. When compared to key rivals and its slab siblings, the iPhone Duo demonstrates impressive capabilities.

On the CPU front, Geekbench 6 scores show the iPhone Duo at 4,722 single-core and 12,708 multi-core, while the A20 Pro in the iPhone Duo scores 4,735 and 12,789 in Geekbench 7. Although the Pro siblings have slight advantages, the difference is minimal, with the Duo maintaining clear competitiveness. When compared to foldable rivals, the Galaxy Z Fold 8 Ultra and Motorola Razr Fold fall short in terms of Geekbench 6 single-core scores, while the Pixel 11 Pro Fold lags significantly.

In the graphics department, the iPhone Duo excels as well. Running 3DMark's Solar Bay Unlimited test, the Duo achieves 62.3 fps, which places it between the two Pro flagships. Notably, none of its competitors can surpass the 50-fps mark, making the iPhone Duo stand out with a 32% GPU performance advantage over the Galaxy Z Fold 8 Ultra.

This translates to smoother, more fluid gameplay, particularly important for a foldable phone with a large canvas. Overall, the iPhone Duo demonstrates that it is a powerful and capable device, capable of holding its own against both foldable and traditional flagship smartphones.
