Apple unveils the 2nm A20 Pro, featuring a 6-core CPU with two up to 20% faster super cores, an up to 40% faster 7-core GPU, and 32 Neural Engine cores in total

Apple today revealed the A20 Pro chip in the iPhone 18 Pro and iPhone 18 Pro Max, built on a brand new architecture using 2nm process technology.

Context & Ripple Effects

Apple’s mobile silicon arc has moved from the 5nm A15 and its 16-core Neural Engine in 2021 to a 2nm A20 Pro with 32 Neural Engine cores. The change pairs a process-node advance with a more explicitly heterogeneous CPU, GPU and neural-compute design.

The A20 Pro also brings iPhone silicon closer to themes in Apple’s M5 Pro and M5 Max architecture, where GPU-side neural acceleration was a central part of the pitch. Public reaction focused on the claimed GPU, memory-bandwidth and efficiency gains rather than CPU clock speed alone.

First-order effects

Apple’s iPhone 18 Pro and iPhone 18 Pro Max gain the A20 Pro’s 2nm architecture, two high-performance CPU cores, seven-core GPU and 32-core Neural Engine as their compute baseline.
The claimed up-to-40% GPU gain makes graphics and neural-processing performance a more prominent differentiator for Apple’s Pro iPhones.

Second-order effects

Apple’s iPhone hardware and software teams must make use of the larger Neural Engine and GPU uplift to turn silicon specifications into visibly better on-device experiences.
Commentator David Imel characterized Apple’s GPU claim as a comparison with Google’s Tensor, increasing the pressure for rival premium-phone chips to compete on AI and graphics performance alongside CPU performance.

Third-order effects

If Apple continues to carry CPU, GPU and neural-accelerator design ideas across A-series and M-series chips, its product lines will increasingly share a common on-device AI compute foundation rather than treating phones and Macs as separate silicon tracks.
The move to 2nm reinforces process technology and specialized accelerators as joint levers for premium-device differentiation, with efficiency as important as peak throughput.

The trend: Premium-device silicon is converging on heterogeneous, on-device AI compute, combining advanced process nodes with CPU, GPU and dedicated neural accelerators.

A20's 2nm efficiency plus improved vapor chamber means biggest battery claims for iPhone yet: 18 Pro should be same as 17 Pro Max. And 18 Pro Max should be “30 hours of usage” and charges faster: 50% in 15 minutes. Not ground breaking, but definitely welcome

The A20 Pro has a massive improvement It now has Super cores (same as M6, they said desktop class), 7-core GPU with FP8 neural accelerators for 2x perf, new microarchitecture changes Oh and dual-ANE with 8-bit support and 50% higher memory bandwidth all around

Apple now dual Apple Neural engine with new A-series and M series SoC. Also wider memory bandwidth and advanced packaging for memory now sitting next to compute blocks.

I've never seen an uneven amount of cores. Is it binned?
@mkbhd Marques Brownlee on x
A20 Pro chip - 2nm process node - 6-core CPU - 7-core GPU - Doubled 32-core neural engine - 50% more memory bandwidth
@davidimel David ImeI on x
Apple touts “up to 40% GPU performance increase” - might be a pretty strong swipe at Tensor

The new Apple A20 Pro SoC seems to use the new “Super-cores” that come with a private L2 cache. Interesting.
@davidimel David ImeI on x
A20 silicon is now connected directly to the vapor chamber, which Apple says should dramatically increase thermal performance.
@viticci Federico Viticci on x
Apple is really going hard on gaming and local LLM performance with the A20 Pro. 40% faster graphics, M series-like chip packaging, another Neural Engine for a total of 32 cores. Very keen to see what local models run on this thing. #AppleEvent
