Apple Launches Its Own CPU, the 1GHz A4

Apple's purchase of PA Semiconductor not too long ago, yielded its first product today, but it's not the fact that it was used in the iPad that makes it special. What's special is that Apple now has a real processor on its hands. And in case you're wondering whether or not Apple's own CPU can compete with the likes of ARM's Cortex or Qualcomm's Snapdragon CPUs, the A4 has potential to kick the living shnizzles out of those CPUs.

First, the A4 runs at a 1GHz frequency, which by mobile CPU standards, is quite high. Considering that Qualcomm's 1GHz Snapdragon powers Google's Nexus One, the Apple A4 could power the next wave of super-smartphones. In fact, at its current spec and frequency, the Apple A4 can play back HD video for 10 hours before requiring a full battery charge.

As of currently, other specs about Apple's A4 CPU are scant, but we're sure things will be more clear in the next coming weeks. We can see from the iPad's capabilities that the A4 is potent, but things are still fresh and we'll have to wait and see what software developers can come up with.

What the iPad showcases today and what it's an indication of, is a lot more interesting than the iPad itself.

唔知功耗幾多同SIZE大唔大, 如果細可能下一代IPHONE都用佢

P.A. Semi 設計, 交 Samsung 生產.
ARM core 的 SoC, 不知是否ARM Cortex A9 MP (Dual Core) ?
GPU 應該是 PowerVR SGX, 性能對比 iPhone 3GS 所用的有否加強就唔清楚.
