If this is true, then it would be PASemi teams first product - after 4 years! That is a long time for this much hyped acquisition to be paying dividends and after all that the performance is comparable to the A15? That is a shame.

I would argue that the application processor is now rivalled in importance by the graphics processor. So in this case it is likely an ARM, Imagination combination.

Does it matter what Apple has done? Today, put HTC phone in iPhone package, college grads will take loans or charge credit cards to get it. No one wants to know what is in there. It a fraternity!

First die shots are over on anandtech. Confirms dual arm cores. Also confirms 3 gpu cores (543MP3). Now where is that techinsight article that was posted here a few days back that stated the gpu was being switched to Mali ?

It was anandtech that first came out with the "speculation" that the A6 has some in house cores rather tahn A15. Linley and others are merely embellishing in that. Best to wait till someone like Chip works does a teardown on iPhone 5 and carries out a similarity analyses with SoCs following pure ARM designs - like Samsung's Exynos in the S3.

I would contend that the difference between a custom core from Apple and the Cortex-A15 from ARM may not be the black and white choice it is at first glance. see http://www.eetimes.com/electronics-news/4396818/Could-Apple-A6-be-a-big-little-processor

A custom ARM core from Apple! Awesomeness. Saw the benchmarks. A6 easily beats the quadcore A9s from Samsung and Nvidia.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
