Apple A12 Bionic GPU (4-core)

64-bit · 512 cores

The four-core GPU of Apple's A12 Bionic, which Apple introduced in September 2018 as the first 7-nanometer chip in a smartphone. Apple rated it up to 50 percent faster than the three-core GPU of the A11 Bionic. It is used in the iPhone XS, iPhone XS Max and iPhone XR, iPad Air (3rd generation), iPad mini (5th generation), iPad (8th generation) and Apple TV 4K (2nd generation).
