Apple's A20 Pro chip puts the iPhone 18 Pro well ahead of Android flagships — for now

Tucked inside the new iPhone 18 Pro and Pro Max is Apple’s latest flagship processor — the A20 Pro. Like most recent silicon announcements, Apple had quite a lot to say about the new chip’s AI number-crunching capabilities, but the processor also quietly boasts significant improvements for everyday workloads. Apple even claims it “sets a new bar for mobile computing.”

The question on the lips of every Android performance enthusiast, then, is whether the A20 Pro will see Apple reclaim the crown as the fastest smartphone. And if it does, can it sustain the lead once next-gen processors from MediaTek and Qualcomm land before the year is out?

The A20 Pro really is impressive

Apple scores early by launching the first smartphone processor built on TSMC’s 2nm manufacturing process, which enables the chip to pack more transistors into a smaller area and run those transistors even more efficiently — with early reports suggesting the A20 Pro could be up to 30% more power-efficient than the A19 Pro.

Starting with the CPU, the A20 Pro boasts two large performance cores, which Apple is classifying as “desktop-class,” presumably owing to their architectural similarities to its custom CPUs inside its M-tier of chipsets. In typical Apple fashion, these two large cores are backed by four efficiency cores to handle daily workloads without heavy battery drain.

In terms of performance improvements, Apple claims this setup is 20% faster than its predecessor. Our testing shows that the Snapdragon 8 Elite Gen 5’s custom Oryon CPU cores hold a roughly 11% lead in multi-core performance over the A19 Pro, while Apple’s last-gen chip has a slim lead in single-threaded workloads.

If Apple’s claims pan out, the A20 Pro’s upgraded CPU cluster should be the fastest in the mobile space. At least until next-gen Android flagships arrive on the market around the end of the year.

But the upgrade that really caught my eye is Apple’s claim of a 40% boost to graphics performance compared to last year. That’s a frankly outrageous gen-on-gen improvement in the current landscape. Currently, the A19 Pro benchmarks anywhere between 15% to 32% behind the fastest Snapdragon phones in graphics workloads, so again, this upgrade should put the iPhone 18 Pro back on top — for now.

To accomplish such a substantial leap, Apple has added an extra GPU core to the configuration, bringing the total to seven graphics cores this year. Combined with unspecified architectural and clock-speed changes and 50% higher memory bandwidth (reported to be expensive LPDDR6), we can start to see where this figure comes from, even if it is a best-case improvement.

Can the iPhone 18 Pro handle the heat?

Sticking with graphics for a moment, my biggest concern with all the powerhouse smartphones that I’ve tested over the past couple of years hasn’t been peak performance, but sustained performance. Processors often benchmark well on short tests but lose a substantial amount of their performance when stressed for several minutes.

To Apple’s credit, recent iPhones have often delivered better sustained performance than the competition, despite offering lower peak graphics performance. For longer gaming sessions of the industry’s more graphically demanding titles, performance between Apple and Android has often been closer than the benchmark suggests.

However, throwing a 40% performance boost and an extra core at the problem risks sending temperatures sky-high as well. Apple appears prepared for this problem by pairing the A20 Pro with a new vapor chamber that couples to both the processor and memory. The claim is 40% better sustained performance than the iPhone 17 Pro and its A19 Pro chip. If this means the A20 Pro retains most of its performance gains under stress, then this could be an incredibly potent little gaming machine.

As with all of these boastful claims, the proof will come when we can finally test the iPhone 18 Pro’s A20 Pro chip in the coming weeks.

It’s all about appearances AI

It wouldn’t be a 2026 chip launch without copious mentions of AI, and the A20 Pro has some notable changes here, too. Apple’s Neural Engine doubles its compute units from 16 to 32 cores this year, making the engine significantly larger than the previous three generations of A-series chips. Paired with significantly faster memory, the A20 Pro should indeed be much faster at crunching through on-device AI workloads. Apple claims there’s twice the compute available, but that doesn’t necessarily mean twice the performance, and it certainly doesn’t tell us where this upgrade stacks up against the competition.

For one, there is such a wide range of workloads, models, and quantization levels that make comparing like-for-like work very difficult. What I find more interesting is that both the Neural Engine and the neural accelerators built into the GPU now support 8-bit floating-point arithmetic. For comparison, Qualcomm’s NPU in the Snapdragon 8 Elite Gen 5 already supports FP8 and lower-precision INT2 and INT4 formats. Likewise, MediaTek’s NPU has supported FP8 and smaller integer formats for a couple of generations now. Unfortunately, Google doesn’t disclose which formats the TPU in its Tensor G6 supports, so we can’t see how these compare.

In any case, 16-bit floating-point math is a very common format for standard models, but 8-bit support means AI processors can crunch through quantized models faster or use less memory bandwidth, both of which are important for running on-device AI under the power constraints of the mobile form factor. While it’s taken some time to catch up, the A20 Pro’s Neural Engine shows that Apple is taking on-device mobile AI far more seriously.

Catching up with the competition

It’s early days for the A20 Pro, and we won’t know for sure just how well the chip performs until we get our hands on the iPhone 18 Pro series. Still, based on what we do know, the A20 Pro is shaping up to be a solid return to form for Apple’s silicon division.

Not that recent iterations have been particularly troubled or lackluster. The A18 Pro and A19 Pro have proven plenty powerful, with the former finding its way into the MacBook Neo, an impressive accomplishment for a mobile-class chip. That said, the last few years have seen Apple surrender some of its long-held performance advantages. Qualcomm’s custom Oryon CPU cores have caught up to, and in some cases exceeded, Apple’s custom smartphone cores, and have also allowed it to rival Macs in the Arm laptop space. And that’s before we talk about graphics and AI, areas where many of Apple’s mobile competitors have leapfrogged the iPhone in the past couple of generations.

The A20 Pro once again looks highly competitive in the classic CPU and GPU metrics, which is great for content creators and gamers alike. The Neural Engine upgrades also suggest that Apple intends not to be caught napping on the AI front ever again. Though it’ll still need more compelling software features to make use of these new hardware capabilities.

We’ll just have to see if next-gen chips from MediaTek, Samsung, and Qualcomm, expected to debut in Android phones in the coming months, have enough firepower to propel themselves back in front. Apple’s latest lead will probably be short-lived, but it won’t be that far behind either.
