GTA V Hits 80 FPS on iPhone 18 Pro Max: A20 Pro Reaches GTX 1650-Level Performance

GTA V for PC has been run through emulation on the iPhone 18 Pro Max, powered by Apple’s new A20 Pro chip. In a September 27 test by the creator of a project called Vapor, the game averaged 66 FPS in the city at 1080p in DirectX 11 mode and around 80 FPS in other scenes. The test used high textures, FXAA, 16x anisotropic filtering, 75% population density and 50% distance scaling.

The result is noteworthy because this is not a special version of GTA V developed for the iPhone, but the PC game being run on the phone through emulation. Based on these results, the A20 Pro is reported to deliver performance in GTA V close to the GeForce GTX 1650 level.

The GPU is not the only factor behind the A20 Pro achieving this result; the 2-nanometer manufacturing process and new cooling system also play a role. The chip uses a 7-core GPU, and Apple says GPU performance has increased by up to 40% compared with the previous A19 Pro. The iPhone 18 Pro series also features a vapor chamber with 3 times the surface area of the previous generation and a new packaging system that moves the memory out of the chip’s thermal path. Apple says these changes increase sustained performance by up to 40%.

The most striking claim is that the A20 Pro can deliver 1180% higher performance per watt than the GTX 1650. Since real-world power consumption under the same conditions and identical benchmark measurements have not been disclosed for both the iPhone and the GTX 1650, the 1180% figure cannot be independently verified. However, the iPhone 18 Pro Max can already comfortably run GTA V for PC through emulation at more than 60 FPS at 1080p.
