Apple A6 Found To Have Custom Apple Core Instead Of A15 Or A9By cheatmaster 08:01 Wed, 14 Jul 2021 Comments
When Apple announced the iPhone 5, the only details they revealed about the recent processor was that it was called the A6 and that it was twice as quick as the older one in Central Processing Units (CPU) as well as the GPU.
Rumors started circulating shortly afterwards that Apple was seemingly using the brand recent ARM Cortex A15 cores for the CPU, being the first in the industry to do so. Turns out, that's not the case after all.
Thanks to some super sleuthing by AnandTech, it has now been revealed that Apple is neither using the recent A15 nor the older A9. Instead, Apple has chosen to go with a custom design based on the armv7s architecture instead of licensing a specific core like the A9 or the A15.
This is similar to what elegant Qualcomm does for its CPUs, such as the Scorpion or the Krait, which are based on the ARM architecture but utilize Qualcomm's custom core.
This go would give Apple greater control over the size, performance and the power consumption of the recent chip, something you can achieve better with a custom chip than off-the-shelf ones.
As for the GPU, things are still fuzzy at the moment but AnandTech is guessing it could be the PowerVR SGX543MP3, a faster version of the SGX543MP2 used in the A5. It's unlikely Apple would have gone for the PowerVR SGX543MP4 used on the A5X, due to its large size and higher power consumption. Besides, that GPU is way more than just twice as quick as the 543MP2.
Things should become clearer once the devices start shipping and people start running benchmarks on them. We'll haged you posted if anything recent comes up.
