After an analysis and high-resolution diffusion images taken of the A6 die, UBM Insights believes that the chip is being manufactured by Samsung in a 28 nm process. AnandTech further showed an image that suggests that Apple is using three PowerVR SGX 543MP3 GPU cores at 266 MHz. There was no information whether the ARM cores are based on ARM's Cortex-A15 or the previous Cortex-A9. However, Apple promised twice the performance of the preceding A5, which is a hint that the switch to the A15 has been made.
UBM Insights said that the A6 die has an area size of 95.04 mm2, down from 162.54 mm2 of the Apple A5X, and down from 122.21 mm2 of the A5.
