Apple A20 Pro Shows GTX 1650-Level Performance in GTA 5 on iPhone 18 Pro Max
Apple’s push into high-end mobile gaming appears to be reaching a new milestone with the A20 Pro. After the A17 Pro first opened the door for console-quality games on iPhone, the newer 2nm A20 Pro is now showing just how far smartphone graphics performance has come.
In a recent GTA 5 performance demonstration, the iPhone 18 Pro Max powered by the A20 Pro reportedly delivered results comparable to Nvidia’s GTX 1650, a dedicated desktop graphics card that has long been considered capable of solid 1080p gaming. What makes the result even more impressive is that GTA 5 is not running as a native iOS game. Instead, it is being played through emulation, which typically adds extra performance overhead.
The benchmark shows GTA 5 running at 1080p with DirectX 11 enabled. During a city driving sequence, the iPhone 18 Pro Max averaged around 66 frames per second. In other benchmark scenes, the average rose to around 80 frames per second. For a smartphone chipset running a demanding open-world PC game through emulation, those figures are remarkable.
The graphics settings used in the test were also fairly respectable. Texture quality was set to high, FXAA and 16x anisotropic filtering were enabled, population density was set to 75 percent, and distance scaling was set to 50 percent. Sharp shadows were turned on, while MSAA was disabled to help maintain smoother performance.
Although the project is still described as a work in progress, the results suggest that the A20 Pro’s graphics capabilities are a major leap forward for mobile gaming. Minor issues reportedly remain, but seeing GTA 5 reach smooth frame rates on an iPhone shows how quickly mobile hardware is catching up to older desktop gaming systems.
A major reason behind this performance appears to be Apple’s upgraded 7-core GPU, but raw GPU power is only part of the story. Sustained performance has always been one of the biggest challenges for smartphones. Unlike gaming laptops or desktops, phones rely heavily on passive cooling and compact thermal designs, which can cause performance to drop during long gaming sessions.
To address this, Apple is said to have introduced a new Wafer-Level Multi-Chip Module packaging design for the A20 Pro. This custom packaging moves the DRAM to the side, giving the chipset more room to manage heat and operate more efficiently. Combined with a larger vapor chamber inside the iPhone 18 Pro and iPhone 18 Pro Max, the A20 Pro can maintain higher performance for longer periods.
This thermal improvement is important because short benchmark bursts do not always reflect real-world gaming. A chip may perform well for a few minutes, but if it overheats quickly, frame rates can fall sharply. The A20 Pro’s new design appears to help reduce that problem, allowing the iPhone 18 Pro Max to deliver stronger sustained gaming performance.
Previous comparisons have already shown the A20 Pro pulling far ahead of the A19 Pro in demanding AAA games. In one test, the iPhone 18 Pro Max reportedly delivered up to 50 percent higher performance than the iPhone 17 Pro Max, while 1 percent lows improved by as much as 77 percent. That means not only higher average frame rates, but also smoother gameplay with fewer noticeable stutters.
The progress in GTA 5 emulation is also worth highlighting. Earlier attempts to run the game on an iPhone through an Xbox 360 emulator struggled to get much beyond 20 frames per second on the iPhone 17 Pro Max. Now, with the A20 Pro and improved emulation work, the iPhone 18 Pro Max is pushing frame rates that are much closer to a traditional 1080p gaming PC experience.
While this does not necessarily mean a native GTA 5 iOS release is around the corner, it does show what modern smartphone hardware is becoming capable of. If developers continue optimizing emulation and if more PC and console games are adapted for iPhone, Apple’s latest Pro devices could become even more serious contenders in portable gaming.
The A20 Pro’s GTA 5 performance is a strong sign that mobile gaming is entering a new phase. A smartphone matching GTX 1650-level results in a game as demanding as GTA 5 would have sounded unrealistic only a few years ago. Now, with better GPU architecture, advanced chip packaging, and improved cooling, the iPhone 18 Pro Max is showing that AAA gaming on mobile devices is no longer just a marketing promise.
