The Apple A10X Fusion is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc. and manufactured by TSMC. It first appeared in the 10.5" iPad Pro and the second-generation 12.9" iPad Pro, which were both announced on June 5, 2017.[6] The A10X is a variant of the A10 and Apple claims that it has 30 percent faster CPU performance and 40 percent faster GPU performance than its predecessor, the A9X.[6]

Design

The A10X features an Apple-designed 64-bit 2.38 GHz[3] ARMv8-A six-core CPU, with three high-performance Hurricane cores and three energy-efficient Zephyr cores.[5][1] The A10X also integrates a twelve-core graphics processing unit (GPU)[5] which appears to be the same Apple customized Imagination PowerVR cores used in the A10.[7] Embedded in the A10X is the M10 motion coprocessor.[8]

Built on TSMC's 10 nm FinFET process[7] with a die size of 96.4mm2, the A10X is 34% smaller than the A9X and (As of June 2017) is the smallest iPad SoC.[1] The A10X is the first TSMC 10nm chip to be used by a consumer device.[1]

The A10X is paired with 4 GB of LPDDR4 memory in the second-generation 12.9" iPad Pro[9] and the 10.5" iPad Pro,[2] and 3 GB in the 4K Apple TV.[10]

The support of Codecs by decoding and encoding is extended to HEVC 264 and JPEG. HEVC 265 (8/10bit), VP8, VP9, AVC and VC1 are available for decoding. AV1 is not supported by hardware. [11]
