Geekbench single-core score indicates the A20 delivers a significant generational CPU performance boost this year.

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.
