Apple’s launch figures describe claimed improvements over the previous generation; a separate Geekbench submission offers one measured snapshot, not a typical score or a guarantee of speed.
Apple A17 Pro specifications
Apple introduced A17 Pro with iPhone 15 Pro and iPhone 15 Pro Max in September 2023, describing it as the industry’s first 3-nanometer chip. Apple’s technical specifications list these core counts:

| Component | Apple A17 Pro specification |
|---|---|
| CPU | 6 cores: 2 performance cores and 4 efficiency cores |
| GPU | 6 cores |
| Neural Engine | 16 cores |
Apple also lists a dedicated AV1 decoder and a new USB controller that enables USB 3 speeds. Its specification page says a USB 3 cable rated for 10Gb/s is required for those speeds; the cable is a separate consideration from the chip itself. Apple lists video output up to 4K at 60 fps HDR. See Apple’s iPhone 15 Pro technical specifications.
What Apple claimed about A17 Pro performance
At launch, Apple compared A17 Pro with the preceding generation and claimed CPU performance up to 10% faster, GPU performance up to 20% faster, and a Neural Engine up to 2x faster. Apple also said its hardware-accelerated ray tracing was 4x faster than software-based ray tracing. These are Apple’s own relative claims, not independent benchmark measurements; the announcement does not provide an independent test method for those exact comparisons. Apple’s September 2023 announcement describes the launch claims and features.

One Geekbench A17 Pro result
One Geekbench Browser submission for an iPhone 15 Pro reported 2612 single-core and 7075 multi-core. It used Geekbench 7.1.0 for iOS AArch64 on iOS 27.0 and was uploaded September 19, 2026. The result page identifies a six-core CPU with a 3.78 GHz base frequency: Geekbench result 402667.
This is one submitted result, not an Apple result, a controlled aggregate, or a representative average across phones. Benchmark scores can vary with device condition, temperature, operating system, and benchmark version. Treat the figures as a dated snapshot rather than a promise of what every A17 Pro phone will score.

How to compare A17 Pro benchmark scores
- Compare single-core with single-core and multi-core with multi-core.
- Use the same Geekbench version; results from different versions should not be treated as directly comparable.
- Check the phone model and operating system, and remember that temperature and device state can affect an individual run.
- Keep Apple’s “up to” generational claims separate from benchmark submissions: they answer different questions and use different evidence.
Which devices have the A17 Pro?
Apple specifies A17 Pro in both iPhone 15 Pro and iPhone 15 Pro Max. The chip specification is therefore not a distinction between those two models; choose between them based on the phone-level features and requirements that matter to you. The sources cited here do not establish A17 Pro as a standalone retail chip.
