"the use of Cortex-A15 could help explain how Apple has achieved the equivalent talk time to the previous iPhone 4S" - no it couldn't. The die shrink from 45nm to 32nm would explain that. Why does EETimes keep publishing baseless speculation from unqualified analysts? The analysts in that iphone 5 predictions article yesterday got 2 out of 9 predictions correct.

Better Power efficient architecture -- lower power consumption. Process is just one part of the power puzzle.

there is a pro-ARM ( pro Brit ) agenda being pushed here by the reporter based in Londonistan at the expense of giving US readers of EE Times a well-informed or balanced perspective. Thx to EE Times employment policies we will just have to do it ourselves.

Conspiracy everywhere. hah? BTW I dont think ARM necessarily needs a boost by EETimes. Its already so far ahead of Intel

"Its already so far ahead of Intel" Power consumption -- yes Performance -- no.

This should be an interesting mix of processing power vs battery life. If the performance has been jacked up to 2x as they claim then assuming it consumes the same power as it's predecessor it should still result in longer battery life and faster response times. So I guess the quad core version of it will go into next Ipad.

Yeah, and which factor is more important in the fastest growing market segment?

@neo1 And dont forget there is the chance to upgrade with a couple of Cortex-A7 cores tucked in to a corner of a dual-core Cortex-A15 processor design. That would create a quad-core processor that implements the "big-little" power-saving technique. Such chips are expected to arrive and be powering smartphones in 2013 as I remember Warren East saying at the launch of Cortex-A7 in 2011.

Well in my opinion it is too early to see an A15-based SoC powering such an important and high volume product as the iPhone. The 2x claim by Apple is quite unsubstantial and not based on a specific metric (e.g. a benchmark). Therefore compared to the A5 processor in iPhone 4S, my best guesses are that this "2x claim" could come from the following: - using 32nm process instead of 45nm could lead to an increase from 1GHz dual A9 to 1.5 GHz (maybe more?) again dual A9 - certain tweaks here and there - beefier memory subsystem (maybe another memory controller or higher frequency DRAM?) - beefier graphics and... - software improvements.

I understood them to say 2X over the A5 - in the iPhone 4S, not the A5X - which resides in the 3rd generation iPad.
