“Meanwhile, we went straight to work on performance testing. As we’ve mentioned before, the A6 SoC makes use of a pair of Apple’s own CPU cores that implement the ARMv7 ISA,” Lal Shimpi reports. “These aren’t vanilla Cortex A9s or Cortex A15s, but rather something of Apple’s own design. For its GPU Apple integrated a PowerVR SGX543MP3 GPU running at higher clocks than the dual-core 543MP2 in the A5.”
Lal Shimpi reports, “The result is compute performance that’s similar to the A5X in Apple’s 3rd generation iPad, but with a smaller overall die area. The A6 has a narrower memory interface compared to the A5x (64-bits vs. 128-bits), but that makes sense given the much lower display resolution (0.7MP vs. 3.1MP).”
