Apple is powering its premium iPhone 15 models with the 3nm A17 Pro chipset which includes a pro-class GPU.
The A17 Pro continues to use a 2+4 configuration with the two high-performance CPU cores running up to 10% faster with a maximum clock speed of 3.78GHz. That compares to the maximum P-core clock speed of 3.46GHz on the A16 Bionic. The four high-efficiency cores have a clock speed of 2.11GHz, and Apple says that its E-cores are three times more efficient than the competition.
Apple has improved the six-core GPU calling it"Pro-Class." The GPU runs 20% faster but remains energy-efficient. One big change Apple made was to feature"Hardware-accelerated ray tracing" which is up to four times faster than software-based ray tracing. Ray tracing simulates the physical behavior of light which makes video games look more realistic. And having it built into the hardware enables the A17 Pro to deliver ray tracing in real-time at 30fps.
The GPU also supports Mesh shading which will also improve how realistic games look. The bottom line here is that Apple is beginning to take the GPU used on a mobile device like the iPhone, to desktop levels. The A17 Pro includes Qualcomm's Snapdragon X70 5G modem which offers AI capabilities not found on the A16 Bionic's Snapdragon X65 5G modem. The X70 5G modem also supports all commercial 5G bands from 600MHz low-band spectrum to 41GHz mmWave. And on theApple had been hoping to introduce its own homegrown 5G modem chip for the iPhone this year.
