TL;DR: Apple says A20 Pro adds a 7-core GPU, a 32-core Dual Neural Engine and 50% more memory bandwidth than A19 Pro.[1] Its redesigned package also improves the route from silicon to the phone’s vapor chamber.[5] Compared with A17 Pro through A19 Pro, Tensor G6, Snapdragon 8 Elite Gen 5, Dimensity 9500 and Exynos 2600, the meaningful story is how each platform combines compute, memory, cooling and software to run useful local AI.
What this means for a phone purchase: Start with the local AI feature you need, then check whether the phone and its software support it. The chip specifications below explain potential constraints, but they do not establish an A20 Pro versus Android winner. For sustained workloads, look for tests using the same model, precision, context length and thermal conditions.
The real story isn't an A20 Pro victory lap. It is Apple moving closer to the constraint that shapes local generative AI after a model fits: memory traffic, sustained power, and the runtime sitting between a model file and the silicon. That is a sharper strategy than chasing a single TOPS number, but it leaves Apple with the same execution problem as everyone else. Hardware capability does not make a useful assistant, and it does not settle the local-versus-cloud boundary.
Apple has disclosed a 2-performance-core plus 4-efficiency-core CPU, 7-core GPU, Dual 16-core Neural Engine, and 50% more unified-memory bandwidth for A20 Pro.[6] The significance is headroom for a shipped phone-and-runtime combination, not a claim that one published percentage proves a universal AI winner.

Apple’s Four-Chip Arc: The New Bottleneck Is Memory Movement
A17 Pro made the iPhone a more credible high-end graphics device. Apple called it the industry’s first 3-nanometer chip, added a 6-core GPU and hardware-accelerated ray tracing, and said its Neural Engine was up to twice as fast as its predecessor.[2] A18 Pro then made the memory system explicit: Apple disclosed a 6-core CPU with two performance and four efficiency cores, a 6-core GPU, a 16-core Neural Engine, and 17% more total system-memory bandwidth.[3]
A19 Pro changed the design language again. Apple highlighted Neural Accelerators in each GPU core, a 16-core Neural Engine, larger cache, more memory than A18 Pro, and a vapor chamber in iPhone 17 Pro. Its up-to-40% sustained-performance claim belongs to that cooled phone, not to a naked chip on a comparison chart.[4]
Now A20 Pro retains the six-core CPU, adds a seventh GPU core, and doubles the Neural Engine core count to 32. Apple’s Duo technical specifications identify the CPU as two performance “super cores” plus four efficiency cores. Apple says the new chip has 50% more unified-memory bandwidth than A19 Pro, up to 20% faster CPU performance, up to 40% faster GPU performance and twice the Neural Engine compute. It does not publish RAM capacity, absolute GB/s bandwidth, clocks, watts, TOPS, or an end-to-end model benchmark harness.[1][5][6]
