AnTuTu scores suggest that the iPhone 12 chipset is downclocked, the GPU is slower than in the 11 series

In the past, we have seen X versions of Apple 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 for the new Air and the iPhone 12 series, both use the Apple A14 standard chipset. There’s an Apple A14X on the way, but that Chipset is supposed to be destined for the new MacBooks.

AnTuTu does not list CPU and GPU clock speeds, but judging by these results, Chipsets inside iPhones have a lower frequency than those inside the iPad. It’s not a big difference, but it’s there.

We point out that the score of the iPhone 12 is actually slightly lower than the iPhone 11 Pro in the GPU benchmark, although Apple’s official figures say that Apple’s A14 GPU should be 8% faster than the A13. This may be true for the iPad, in fact its score is 20% higher than that of the iPhone 11 Pro, but the lower Clock puts the iPhone 12 series in a difficult position.

We point out that both the iPhone 12 and the iPad Air (2020) that were tested have 4 GB of RAM and 256 GB of storage, so the memory should not have affected the results. Both screens operate at 60 Hz as well, the same for the 11 Pro.

Apple’s chipsets are getting smaller in size and bigger in transistors, the A14 has 11.8 billion transistors. Although it is built on a 5 nm process, it is an energy hungry animal and therefore Apple probably had to lower frequencies due to heat and battery life considerations. The larger iPad has a bigger battery and more space to dissipate heat.
