[讨论] 各版本的iphoneCPU频率不同

700我晕!!!!!!!!!!!!!

TOP

超iphone,上700MHZ玩PS不错

TOP

iphone的cpu就是可以达到700的那种,不过如果升到700,不知道还能待机多久了!
我估计最多也就到500了!

CPU         620 MHz ARM 1176

就是三星的 Samsung S3C6400 ARM CPU。

http://www.engadget.com/2007/07/ ... r-found-620mhz-arm/

    *  ARM1176JZF chip with TrustZone (enables trusted computing environment for media, apps, network, OS, etc. -- very bad for hackers)
    * Can vary in clock speed up to 700MHz or more, depending on implementation (thanks, Nigma)
    * ARM Intelligent Energy Manager (claimed to reduce power consumption 25-50% in portables)
    * 16K / 16K cache
    * Features vector floating point coprocessor ("for embedded 3D-graphics")
    * ARM Jazelle enabled for embedded Java execution (hmm...)
    * SIMD, high perf integer CPU (8-stage pipeline, 675 Dhrystone, 2.1 MIPS)
    * 0.45 mW/MHz power draw (with cache)

Whatever it is Apple's got that thing doing, they're doing it right. Thus far our iPhone battery life tests have far exceeded expectations (more on that soon).

Update: Sascha at Gear Log seems to think given the recently discovered Samsung chip in the iPhone, perhaps the processor in question is a Samsung S3C6400, a recently-produced 667MHz ARM1176JZF-based CPU that seems to fit the bill.

LS正解,这颗ARM11处理器是相当强悍的

说是620的cpu,那为什么运行时只有412呢~~~怎么也要上500吧~~~

主要是省电啊,就象PSP那样,CPU降频了~~

超频功能没啥用,电池肯定扛不住,但600的u跑400也忒浪费了吧?!
不过现在这应用400应该也差不多够了,以后有更强大的应用时应该方便扩展!
要是跟PSP似的,运行音乐和电子书以及待机时自动降频那就更省电了!

!!

1.1.3也是412的

很好!很强大!
