In benchmark tests using Geekbench 7, the iPhone 18 Pro recorded a single-core score of 4030 and a multi-core score of 10,000 1507, surpassing the iPhone 17 Pro (single-core 3301, multi-core 9185). In GPU tests as well, the iPhone 18 Pro recorded 60,000 1566, significantly increasing the value from the iPhone 17 Pro's 40,000 4062. In the AnTuTu Benchmark overall score, the iPhone 18 Pro recorded 3.45 million 1830, significantly pulling ahead of the previous generation's 2.4 million 5029.
Regarding AI processing performance, tests conducted with Geekbench AI showed high performance, such as the CPU processing quantization score reaching 9088 (no data provided for iPhone 17 Pro). Furthermore, results significantly exceeding the previous generation model were obtained in processing using the Neural Engine, a processor dedicated to AI processing.
On the other hand, challenges regarding heat generation during heavy workloads were also observed. When measuring the surface temperature while running AnTuTu Benchmark, the hottest part of the iPhone 18 Pro reached 41.0 degrees, exceeding the 40.1 degrees of the iPhone 17 Pro. In particular, there is a tendency for the entire back of the device to become hot. Apple explains that by adopting a next-generation vapor chamber (steam cooling system) with three times the surface area, they have improved the ability to dissipate heat externally, enabling long-duration execution of high-load games and AI processing.
