Apple A17 Pro vs Apple M2 vs Apple A18 Pro

Apple A17 Pro

The Apple A17 Pro is a System on a Chip (SoC) from Apple that is found in the iPhone 15 Pro (2023) models. It offers 6 cores divided in two performance cores (up to 3.78 GHz) and four power-efficiency cores (up to 2.11 GHz). Thanks to the higher clock speed and improvements of the branch prediction and a wider design, the A17 is able to be around 10% to 15% faster than the A16 SoC.

The biggest improvement is the new integrated 6-core GPU with ray tracing and mesh shading support. Furthermore, the chip is now able to decode AV1 video in hardware and supports USB 3.2 Gen 2 (10 Gbps). The Neural Engine still offers 16 cores, but should be up to twice as fast now.

The A17 Pro integrates 19 Billion transistors and is manufactured in the bleeding edge 3nm (N3B) process at TSMC.

Apple M2

The Apple M2 is a System on a Chip (SoC) from Apple that is found in the late 2022 MacBook Air and, MacBook Pro 13. It offers 8 cores divided in four performance cores and four power-efficiency cores. The big cores offer 192 KB instruction cache, 128 KB data cache, and 16 MB shared L2 cache (up from 12 MB). The four efficiency cores are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. The efficiency cores (E cluster) clock with  up to 2,4 GHz, the performance cores (P cluster) with up to 3,5 GHz and therefore higher than the M1 cores. The architecture should be similar to the A15 (iPhone 13) with Avalanche and Blizzard cores.

The chip features a unified memory architecture for the CPU and GPU cores and supports up to 24 GB LPDDR5-6400 for a bandwidth of up to 100GB/s.

According to Apple, the M2 offers a 18% higher CPU performance at the same power consumption level compared to the Apple M1. In our tests, the MacBook Pro 13 with active cooling was able to reach the 18% in Geekbench Multi. In other benchmarks we measured 12 to 15% gains compared to the M1. Therefore, the performance is now near the M1 Pro with 8 cores. The passively cooled MacBook Air may however suffer from throttling in longer load scenarios.

The integrated graphics card in the M2 offers 8 or 10 cores and a peak performance of 3.6 TFLOPs.

Furthermore, the SoC integrates a fast 16 core neural engine with a peak performance of 16 TOPS (for AI hardware acceleration), a secure enclave (e.g., for encryption), Thunderbolt / USB 4 controller, an ISP, and media de- and encoders.

The Apple M2 includes 20 billion transistors (up from the 16 billion of the M1) and is manufactured in the second generation 5nm process at TSMC (most likely N5P). The power consumption is rated at 20W what we also measured under CPU load.

Apple A18 Pro

The Apple A18 Pro is a powerful smartphone processor and formal successor to the A17 Pro. This new member of the Apple A processor series debuted in September 2024 alongside the iPhone 16 Pro and iPhone 16 Pro Max; it features 2 performance cores and 4 efficient cores along with a 35 TOPS NPU and the 6-core A18 Pro GPU.

The chip is said to be in large part based on the v9.2A ARM microarchitecture for near-Apple M4 IPC. 5G, Wi-Fi 7, Bluetooth 5.3, various satellite navigation systems and NFC are all supported here.

The more affordable A18 SoC has the same 2 P-cores and 4 E-cores running at slightly lower clock speeds along with a significantly slower graphics adapter. The Pro version of the chip also boasts USB 3.x support whereas devices powered by the A18 are limited to USB 2.0 speeds.

Performance

Its multi-thread benchmark scores leave the Dimensity 9300 as well as the Apple A17 Pro and the Apple A18 pretty far behind with at least a 10% advantage. Overall, Apple M1-like performance is to be expected in short-term workloads.

In the meantime, its single-thread performance comes dangerously close to the M3 and M4 chips despite their higher clocks speeds and slightly more advanced architectures. (The A18 Pro's performance cores can run at just slightly over 4.0 GHz, as far as we know.)

Performance drops are inevitable when under longer-term stress since there is no active cooling solution of any kind here.

Graphics

Like any modern graphics adapter, the 6-core A18 Pro GPU is RT-enabled. It delivers benchmark scores that are most comparable to the Immortalis-G720 MP12, Adreno 740 and Adreno 750; as a matter of fact, it even manages to beat the 7-core M1 GPU in many tests which is rather impressive. Any 2024 and 2025 iOS game will be happy with such an iGPU.

Power consumption

It appears the chip is able to briefly consume up to about 10 W when under high load, with average sustained power consumption figures hovering around 4 W.

The pretty modern TSMC N3E manufacturing process makes the A-series chip very power-efficient, as of late 2024.
