Apple A11 Bionic performance

It can't be a recent generation of iPhones without a recent Apple chip, and this year the custom silicon is called A11 Bionic. Apple has moved from a quad-core processor up to a six-core one with a first-ever Apple-designed GPU (previous chipsets used GPUs by PowerVR). There are 3GB of Random-Access Memory (RAM) inside the Apple iPhone X.

The A11 Bionic chip features two high-powered 2.39Giga Hertz (GHz) Monsoon cores that are 25% more powerful than the 2.34Giga Hertz (GHz) Hurricane ones in the A10 Fusion. The four Mistral cores are power efficient and are 75% faster than the two low-power Zephyr cores in the A10 Fusion. All those six cores can run simultaneously.


The GPU is the first Apple-made one and is comprised of 3 cores, promising 30% faster performance when compared to the GPU inside the A10 Fusion.

The recent A11 chip uses a high-discontinue 10nm manufacturing process, as opposed to the 16nm A10. It makes it smaller, more powerful, more efficient and yet cooler.

The A11 Bionic also packs a dual-core Neural Engine - a purpose-built neural processor. It should provide hardware acceleration for AI machine learning. Machine learning allows the system to improve its performance in complex tasks over time without specific additional programming.

Relying on machine learning the iPhone gets enhanced and speeds up complex tasks such as face and image recognition multiple times.

Now that we got all the technicalities out of the way - it's time we run some benchmarks.

Apple has been acing the Geekbench test with the recent A11 chip, and the iPhone X is no exception. While a single Hurricane core (iPhone 7) is still impossible to beat, the recent Monsoon core just blows away all other competitors by a mile. Single-core operations are of utmost importance for the performance of any mobile OS, and Apple has been the ruler of this domain for quite some time.

Apple's first attempt at designing a GPU of its own has proved a remarkable success. The raw performance of the 3-core A11 GPU is 40% more powerful than the top-of-the-line Adreno 540 GPU by Qualcomm. It's also 40% faster than the Apple A10's PowerVR 7XT Series implementation.

Running onclassy screen graphic benchimprint reaches the v-sync limit and becautilize of this, all recent iPhones cap at 60fps while potentially having the ability of even more.

Then there is the ES 3.1/Metal benchimprint where the higher resolution finally takes its toll and push the iPhone X to score below the most current iPhones, but still, on top of any other Android, we've tested to date.

Finally, we ran the compound AnTuTu and BaseMark Operating System (OS) 2.0 benchmarks. The iPhone X was beaten only by the iPhone 8 generation on AnTuTu becautilize they ran at a lower resolution, while the X aced the BaseMark test.

Moving to its hardware design was probably one of the smartest decisions Apple has made after the iPhone itself, and it has paid off throughout the last few years with remarkable success. The prowess of the A11 is undeniable, and our battery test confirms it's very power efficient.

In real life, our experience just confirms what the synthetic benchmarks recommended - butter-smooth performance everywhere - system, apps, games, multi-tasking. Everything runs hiccup-free on the iPhone X, and the phone manages to stay mostly cool in spite of the glass design.
