A12 Bionic Chip

Every year when Apple comes out with a new iPhone, it makes sure to upgrade on one thing that is the chip used inside the iPhones. This year’s iPhone Xs and iPhone Xs Max have A12 Bionic chip inside them which is the successor of the last year’s version A11 Bionic.

A12 Bionic Chip upto 40% Faster than A11 on iPhone Xs

In Andrei Frumusanu’s deep dive review for AnandTech, he took an in-depth look at the A12’s performance in the iPhone Xs/Xs Max. The deep dive tests claims that the new A12 Bionic is upto 40% faster than the A11 Bionic whereas Apple claims that it is just 15% faster than the last year’s A11 Bionic.

He also mentions that the A12 is as good as “the best desktop CPUs” which gives more credence to the rumours of Apple switch to using its own chips in Macs as soon as 2020.

A12 Bionic Chip Performance Test upto 40% Faster than A11 on iPhone Xs / Xs Max

Apple’s marketing department was really underselling the improvements here by just quoting 15% – a lot of workloads will be seeing performance improvements I estimate to be around 40%, with even greater improvements in some corner-cases. Apple’s CPU have gotten so performant now, that we’re just margins off the best desktop CPUs; it will be interesting to see how the coming years evolve, and what this means for Apple’s non-mobile products.

When it comes to the GPU, Frumusanu says it stacks up to Apple’s claims, but might do better to enable greater use of throttling.

On the GPU side, Apple’s measured performance gains are also within the promised figures, and even above that when it comes to sustained performance. The new GPU looks like an iteration on last year’s design, but an added fourth core as well as the important introduction of GPU memory compression are able to increase the performance to new levels. The negative thing here is I do think Apple’s throttling mechanism needs to be revised – and by that I mean not that it shouldn’t throttle less, but that it might be better if it throttled more or even outright capped the upper end of the performance curve, as it’s extremely power hungry and does heat up the phone a lot in the initial minutes of a gaming session.

The review also talks about the camera and battery performance on the iPhone Xs.

On the camera side, Apple made some very solid improvement all-around. The new sensor’s increased pixel size allows for 50% more light sensitivity, but the improved DTI of the sensor also allows for significantly finer details in bright conditions, essentially increasing the effective spatial resolution of the camera. SmartHDR works as promised, and it’s able to produce images with improved dynamic range.
