Apple A17 Pro: The Complete Guide

Apple’s release calls its GPU redesign “the biggest GPU redesign in Apple’s history” 1 — the same generation that brought hardware-accelerated ray tracing to an Apple chip for the first time.

Apple’s own framing: hardware-accelerated ray tracing is “4x faster than software-based ray tracing” — a same-chip comparison against running the same technique without dedicated hardware, not against a prior Apple chip 1. The release also names a new dedicated AV1 decoder and states “a new USB controller enables USB 3 speeds on iPhone for the first time” 1.

Apple’s own performance claims, framed against “the previous generation” without naming A16 Bionic outright: CPU “up to 10 percent faster with microarchitectural and design improvements”; Pro-class GPU “up to 20 percent faster”; Neural Engine “up to 2x faster,” specifically powering “autocorrect and Personal Voice in iOS 17” 1. Since A17 Pro’s only immediate predecessor at the Pro tier is A16 Bionic, this page reads the comparison as being against A16 Bionic — a reasonable inference, not a chip name Apple’s own release states directly. Apple has not disclosed a transistor count for A17 Pro in any official source found — a commonly-cited “19 billion” figure traces to third-party commentary, not apple.com, and is not repeated here as fact. A Neural Engine TOPS figure is also not disclosed for this generation.

Apple’s own words: “industry’s first 3-nanometer chip” 1. TSMC’s Q3 2023 earnings call, held the following month, has CEO C.C. Wei stating N3 “is already in volume production with good yield and we are seeing a strong ramp in the second half of this year,” a ramp “supported by both HPC and smartphone applications,” with 3-nanometer process technology contributing “6% of wafer revenue in the third quarter” 3. TSMC’s own transcript does not name Apple specifically — this page reports the timing correlation rather than asserting a named-customer confirmation neither company has made.

Unlike A15 Bionic’s single-name, dual-GPU-bin approach, A17 Pro had no non-Pro counterpart that year — iPhone 15 and 15 Plus used A16 Bionic instead 1.

No official Apple source lists a standalone chip price for A17 Pro.

These are all company-published comparisons. The ray-tracing figure is unusual in comparing the chip against itself running the same task without dedicated hardware, rather than against a prior Apple generation or a named rival 1.

A17 Pro set two precedents its successors kept: the “Pro” chip name itself, and hardware ray tracing as a standing Apple GPU feature, carried into every subsequent generation through 2026’s A20 Pro.

Apple’s own release states plainly, almost in passing next to the ray-tracing and gaming headlines: “a new USB controller enables USB 3 speeds on iPhone for the first time” 1 — a practical, everyday capability (fast wired file transfer) landing in the same chip generation as a marketing push built almost entirely around console gaming.
