At least for the A4/Hummingbird, Intrinsity optimised the existing Cortex-A8 design for Samsung and before Apple bought them, so you disagree based on faulty facts.
SAMSUNG and Intrinsity Jointly Develop the World's Fastest ARM® Cortex™-A8 Processor Based Mobile Core
"Seoul, Korea, Austin, Texas - July 27, 2009 : Samsung and Intrinsity today jointly announced the industry's fastest mobile processor core implementation of the dual-issue ARM® Cortex™-A8 processor architecture in 45 nanometer (nm) Low Power (LP), low leakage process technology. This Cortex-A8 implementation, code-named Hummingbird, delivers 2000DMIPS at 1GHz. The Hummingbird comes with 32KB each of data and instruction caches, an L2 cache, the size of which can be customized, and an ARM® NEON™ multi-media extension. Performance and power consumption of the Hummingbird have been validated in silicon. Samsung is currently developing standard mobile SoC products using this new core."

Your going to have tell me what you think is wrong, because I can't read minds. I can't see any problem, but I'll rephrase to see if it's just the sentence structure that's confusing you:
Samsung worked with a company called Intrinsity.
They took the Cortex-A8 design, and Intrinsity made it a bit more power efficient.
Samsung sells these chips, and uses them in their devices.
They also sell them to Apple.
Apple gets Samsung to put Apple logos on them, and refers to them as the A4.
Apple bought the company called Intrinsity after all the work on the A4 was finished, nothing they've done in the pay of Apple has any impact on the A4 or Hummingbird core.
I responded to someone claiming that Intrinsity customised the chips for Apple. This isn't true. I linked to a press release that shows this.
