The iPhone SE 4 is rumored to have Apple's A18 chip, while the iPhone 14 has the A16 Bionic chip[5]. The A18 reportedly has a faster CPU, enhanced graphics, and a more advanced Neural Engine compared to the A16 Bionic[4].
A18 Chip Improvements
* CPU Performance The A18's CPU is reportedly 30% faster than the iPhone 15's and 50% faster than the iPhone 14 and 13[4].
* GPU Performance The A18 chip's GPU is 40% faster than the one in the A16 Bionic[4]. The A18 GPU also supports hardware-accelerated ray tracing, which the A16 Bionic does not[4].
* Neural Engine The A18's Neural Engine is twice as fast as the one in the A16 Bionic and can perform up to 35 trillion operations per second[4].
* Memory The A18 features an improved memory subsystem with 17% faster LPDDR5 memory and more RAM than the A16 Bionic[4]. The iPhone SE 4 may have 8GB of RAM, compared to the previous model's 4GB, which will improve multitasking[1].
* Efficiency The A18 is fabricated using TSMCâs advanced 3nm process, which should deliver improved performance and energy efficiency[1]. The A18 CPU and GPU use 35% less power than the chips used in the iPhone 15[4].
