The Apple A15 Bionic features an Apple-designed 64-bit six-core
CPU implementing
ARMv8 with two high-performance cores called
Avalanche running at 3.24 GHz and four energy-efficient cores called
Blizzard running at 2.01 GHz. Apple claims the A15 in the iPhones is 50% faster than the competition. Apple claims the A15 in the iPad Mini 6 is 40% faster than the A12. 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 are active, their operating frequency goes up by 10%, both now running at 3180MHz compared to the previous generation's 2890MHz". The A15 contains 15 billion transistors, a 27.1% increase from the
A14's transistor count of 11.8 billion. It includes dedicated
neural network hardware that Apple calls a new 16-core Neural Engine. The Neural Engine can perform 15.8 trillion operations per second, faster than A14's 11 trillion operations per second (+ 43%). Apple also boosted performance by doubling the system cache to 32MB. The A15 has video codec encoding support for
HEVC,
H.264, and ProRes (iPhone 13 Pro only). It has decoding support for HEVC, H.264,
MPEG‑4 Part 2, ProRes, and
Motion JPEG. A15 is manufactured by TSMC, reportedly on their second-generation 5 nm fabrication process, N5P. ==GPU==
