Iphone S6 Plus - A1699 Octa core, 2GB Ram Hardware Question

It's either the Mali-450 or the Adreno 320 (I found one link which says that). I'd be more inclined to say it's the Mali.

It also has a clock speed considerably lower than 2.5GHz, most devices it comes with run at 1.7GHz, but Mediatek claim it can reach 2GHz.

What do you mean by a cracked version of Google Play?

 

I agree completely that the OS is mocked-up. There is no way it is really running iOS of any sort - it'll just be Android that's been hacked to tell you it is iOS.

I also second El Pres: the more reliable sites I've looked at say Mali 450, and MTK processors generally use Mali GPUs.

 

MediaTek itself states that the cores are "capable of clock speeds up to 2GHz", but production samples are most commonly clocked at 1.7/1.8GHz.

The 6592 has a Mali 450 GPU, as stated previously. Other variants of the 65xx family utilising the ARM big.LITTLE architecture use PowerVR dual-cluster GPUs.
