以Cnet 所的新聞所提, 多核ARM  (也是CPU 的一種) 將於2010 推出, 多核ARM 也可能推出在其他手提電話內

“You’ll definitely see handsets shipping with a dual-core A9 in 2010,” James Bruce, wireless segment manager for ARM, said in a phone interview earlier this week, referring to the next-generation Cortex-A9 processor from ARM.

目前i3GS  可能使用ARM Cortex A8 處理器, 使用者也可以留意速度的分別,不過, 如果Apple 公司明年推出新一款的iphone , 本人也相信當中的ARM 是多核的 (可能是iphone 3G ES 也不定).

“What we’ve done on the A9 is actually make it more power efficient than the A8. The dual-core A9 will be coming out on 45-nanometer rather than the (current) 65-nanometer process,” Bruce said. Generally, the smaller the geometries, the faster and more power-efficient the processor is.
Bruce continued. “With the dual-core running at maximum load there’s probably going to be an increase of about 10 to 20 percent in power consumption but in general day to day use you’re actually going to see better battery life.”

 A9 可能使用45 nm 科技, 也許A9 處理電源效能比A8 的好(約減電能使用量10~20 %),但目前為止, Apple 公司還沒有定案
