What is A17 Pro vs A16 GPU performance?
The GPU with the A17 Pro gets an even bigger improvement over the A16 Bionic with a focus on 3 aspects:
Performance and efficiency
Complex applications
New rendering features
Speed
Apple labels the GPU “pro class” and says the new 6-core design offers 20% faster graphics performance than A16. And it remains efficient for extended gaming sessions thanks to features like mesh shading.
Hardware-based ray tracing
Another big change with the A17 Pro GPU is hardware-accelerated ray tracing. Apple says that offers much smoother graphics at higher frame rates. That’s 4x faster ray tracing than with A16 Bionic.
To highlight the capabilities, developers like CAPCOM say the new A17 Pro GPU has enabled console-quality games like Resident Evil 4 and Resident Evil Village to launch on iPhone (coming soon).
We don’t have any real-world tests for the A17 GPU.
What is the A16 Bionic?
The A16 Bionic is a system-on-chip introduced by Apple in September 2022 with the launch of the iPhone 14 Pro and Pro Max. Like past chips, the A16 Bionic uses 64-bit ARM-based architecture (like Apple Silicon, but unlike traditional x86 PC processors).
A system-on-chip (SoC) is an integrated circuit that includes a CPU, GPU, RAM, and other components. In 2023, Apple put the A16 Bionic into its base iPhone 15 and its Plus model, continuing the trend of using last year’s top-tier chip in this year’s non-Pro iPhone model.
The A16 features six CPU cores with two of them designed for high performance (clocked at just short of 3.5GHz) and four efficiency cores (running at just over 2GHz) for general compute tasks. These cores do most of the “thinking” on an iPhone, including handling background tasks, with the efficiency cores designed to preserve power and extend battery life.
On top of this, the A16 Bionic features five GPU cores running at just short of 1.4GHz, which handle graphics-intensive tasks including 3D gaming and visual effects like iOS transparency. There’s also Apple’s 16-core neural engine for machine learning tasks like identifying faces and objects in your Photos library. The A16 Bionic is equipped with 6GB of RAM and features 16 billion transistors.
The A16 Bionic introduced a new image signal processor (ISP) to improve computational photography abilities. This means better processing of images coming from the camera, resulting in less noise and ultimately better images.
Apple claimed that the A16 Bionic was the first 4-nanometer chip in a smartphone, a term that refers to the size of the transistors. Analysts discovered this is up for debate and that the chip was manufactured on a slightly improved 5nm process (known internally by chip manufacturer TSMC as N4P).
What is the A17 Pro?
The A17 Pro is an updated system-on-chip that first made its way into the iPhone 15 Pro and Pro Max in 2023. It too uses the same ARM-based architecture, but performance is slightly improved with its six-core CPU featuring two performance cores running at just shy of 3.8GHz and four efficiency cores hitting 2.1GHz.
The A17 Pro also ups the total RAM included on the SoC to 8GB, from 6GB last time around.
Apple also improved the GPU, adding an additional GPU core for a total of six cores with Apple claiming a 20% improvement over the A16 Bionic and support for hardware ray tracing and better shading for improved handling of realistic lighting effects in 3D applications.
Apple boosted the transistor count to 19 billion and added hardware support for AV1 decoding, a video codec that’s set to one day replace HEVC. The A17 Pro is manufactured using TSMC’s N3B process, which is considered to produce “true” 3-nanometer chips.
How Much Better is the A17 Pro?
Apple only claimed a 10% improvement in CPU speed over the A16 Bionic when introducing the A17 Pro, and according to many of the benchmarks, this happens to be the case.
Taking a look at the iPhone 15 Pro Geekbench single-core score shows an improvement from 2540 on the A16 Bionic to 2890 on the A17 Pro, while multi-core scores go from 6420 to 7159 respectively.
More impressive at the Metal scores, which measure GPU performance and corroborate Apple’s claim of 20% taking scores from 22574 on the A16 Bionic to 27074 on the A17 Pro.
