The Apple A12 SoC features an Apple-designed 64-bit ARMv8.3-A six-core CPU, with two high-performance cores called Vortex, running at 2.49 GHz, and four energy-efficient cores called Tempest. [4] [5] The Vortex cores are a 7-wide decode out-of-order superscalar design, while the Tempest cores are a 3-wide decode out-of-order superscalar design.
The A12X is an 8-core variant of the A12 (four big cores, four small cores) and Apple states that it has 35 percent faster single-core CPU performance and 90 percent faster overall CPU performance than its predecessor, the Apple A10X. [4]
The Apple A9X is a 64-bit SoC that was announced on September 9, 2015, and released on November 11, 2015, and first appeared in the iPad Pro. [79] It offers 80% more CPU performance and two times the GPU performance of its predecessor, the Apple A8X. It is manufactured by TSMC using a 16 nm FinFET process. [80]
The Apple A18 and A18 Pro feature an Apple-designed 64-bit ARMv9.2-A six-core CPU with two high-performance cores and four energy-efficient cores, a five-core (A18) and six-core (A18 Pro) GPU and a NPU with 16 cores. Both are produced on TSMC N3E (3nm FinFET) and measure 90 mm 2 and 105 mm 2 respectively. [6]
The Apple A14 Bionic features an Apple-designed 64-bit, six-core CPU, implementing ARMv8 [6] with two high-performance cores called Firestorm and four energy-efficient cores called Icestorm. [5] The A14 integrates an Apple-designed four-core GPU with 30% faster graphics performance than the A12. [8]
The A13 integrates an Apple-designed four-core graphics processing unit (GPU) with 20% faster graphics performance and 40% lower power consumption than the A12's. Apple claims their A13's eight-core Neural Engine dedicated neural network hardware is 20% faster and consumes 15% less power than the A12's. [3] [7] [9]
The Apple A12 Bionic chip powering the fifth-generation iPad Mini has a 66% higher clock speed than its predecessor, which had a 1.5 GHz dual-core processor; (the Apple A8 in the previous generation was clocked higher than in the iPhone 6). The Apple A12 Bionic chip has a 2.49 GHz six-core processor. [9]
Apple claims the A15 in the iPad Mini 6 is 40% faster than the A12. [7] An in-depth breakdown by Anandtech revealed that "compared to the A14, the new A15 increases the peak single-core frequency of the two-performance core cluster by 8%, now reaching up to 3240MHz compared to the 2998MHz of the previous generation. When both performance cores ...
