Yesterday we saw the first AnTuTu scores of the Apple A14 Bionic inside the iPhone 12 and 12 Pro. Now results have come out for the same chipset, except this time with an iPad Air (2020) and they are much higher.
In the past, we have seen X versions of Apple’s chipsets used in iPad Pros, for example the A12X had two extra-large cores and a more robust GPU. But as far as we know, this is not the case with the new Air and iPhone 12 series, they both use the standard Apple A14 chipset. There’s an Apple A14X on the way, but that chip is intended for newer MacBooks.
AnTuTu tests the Apple A14 chipset: iPad Air (2020) • iPhone 12
AnTuTu does not list CPU and GPU clock speeds, however, judging from these results, the chips inside iPhones are clocked lower than the iPad. It’s not a big difference, but it’s there.
Note that the iPhone 12 actually scores slightly lower than the iPhone 11 Pro on the GPU benchmark, although official Apple numbers say that the Apple A14 GPU should be 8% faster than the A13. That may be true for the iPad, in fact its scores are 20% higher than the iPhone 11 Pro, but the lower clocks have put the iPhone 12 series in a tough spot.
Note that both the iPhone 12 and iPad Air (2020) that were tested have 4GB of RAM and 256GB of storage, so memory shouldn’t have affected the results. Both displays also run at 60Hz, the same for the 11 Pro.
Apple’s chipsets have grown quite a bit, the A14 has 11.8 billion transistors. Even though it’s built on a 5nm process, it’s a hungry beast and therefore Apple probably had to dial in the frequencies due to heat resistance and battery considerations. The larger iPad has a larger battery and more metal to dissipate heat.
