記得Apple的A系列核心是跟Arm授權，自己設計的，為了這個核心他們還花大錢買了Intrinsity 跟 P.A. Semi，怎麼大家都認為A系列是三星設計的啊。

我沒說是三星開發的 而是他們合作開發的
A4幾乎等同Samsung S5PC110
只是刪減了部份的部件 其餘如晶片佈置幾乎一模一樣
你自己PO的WIKI說明裡面也有講到這點
The Cortex-A8 core used in the A4 is thought to use performance enhancements developed by chip designer Intrinsity (which was subsequently acquired by Apple)[11] in collaboration with Samsung.[12] The resulting core, dubbed "Hummingbird", is able to run at far higher clock rates than other implementations while remaining fully compatible with the Cortex-A8 design provided by ARM.[13] Other performance improvements include additional L2 cache. The same Cortex-A8 CPU core used in the A4 is also used in Samsung's S5PC110A01 SoC.[14][15]
