Apple’s new A20 Pro smartphone chip around 25% faster than its predecessor in leaked benchmark — the 2nm CPU in the iPhone Duo and 18 Pro hits nearly 5 GHz clocks

Why This Matters

A leaked Geekbench 6 result suggests Apple's 2nm A20 Pro delivers roughly 25% more performance than the A19 Pro, exceeding Apple's own 20% claim, with single-core scores that top many desktop PC CPUs. That would make the chip in the iPhone 18 Pro and foldable iPhone Duo a signal of how far mobile silicon has closed the gap with the PC market. The same silicon may also appear in a rumored Neo laptop or desktop.

Key Takeaways
Worth a Look

Apple iPhone 17 Pro — If the A20 Pro leaks have you itching for Apple's fastest silicon, the current iPhone 17 Pro is the one you can actually buy today — and it's the benchmark the new chip is being measured against. It packs Apple's latest Pro camera system, ProMotion display, and the kind of desktop-class chip performance that makes these Geekbench stories so fun to follow.

We reported on the new Apple A20 Pro system-on-a-chip (SoC) for smartphones yesterday, an integral attraction within Apple’s first foldable, the iPhone Duo, and in the iPhone 18 Pro devices. Now the first A20 Geekbench 6 benchmark results are starting to pop up online, and they’re very impressive, particularly in single-core performance. If the result spotted by Longhorn is a typical one, the 4,719 single-core and 12,677 multi-core scores mean the new A20 is around 25% faster than its predecessor. Its single-core score can also make some of the best PC CPUs look anemic.

Apple’s official performance claims are interesting, as usual, but we’re always happy to see the third-party performance indicators start to emerge ahead of independent reviews. Heralding its new 2nm silicon yesterday, Apple might have actually understated the boost the A20 can deliver, with the official line about this “desktop-class” processor being the “fastest CPU in a smartphone,” and a claim that it is ‘just’ 20% faster than the previous gen. However, Geekbench isn’t the best indicator of real-world performance, and this is just a sample of one to sprinkle salt upon.

What are numbers without relevant comparisons, though? For more perspective on Apple’s newest silicon, which might also be thrown into a new Neo laptop (or desktop) in the coming months, check out the table below.

Above, we’ve pitted the Apple A19 Pro from last year’s iPhone 17 Pro as the second comparison column entrant. Apple has worked on multiple angles to deliver improvements over last year. It says that it has both new super-cores and efficiency cores in play. Then there’s the refined 2nm process and the faster clocks, too.

For some wider context, we’ve also tabulated one of Apple’s newest M5 computer chips, a modern Qualcomm Snapdragon Elite X2 laptop chip, and the AMD Ryzen 9 9950X3D2, for a fun desktop PC angle. Less fun is the comparison with the Asus Zephyrus G16 2024 laptop I’m using now, with an AMD Ryzen AI HX 370 chip. Its Geekbench 6 scores of roughly 2,800 / 14,500 are easily outclassed by Apple’s new smartphone processor in 1T tests, but retain a little dignity by winning by ~1,800 points in nT tests.

Apple is opening up pre-orders for its new iPhones with A20 silicon shortly, with retail release on Friday, September 18. It usually lifts review embargoes a few days before retail. We should therefore see a broader range of benchmarks and tests from good sources in the coming week.
