国内的话 I9000 CPU、GPU都要比IP4更强

但可悲的是更强的GPU也没多少游戏软件能发挥

其他的 I9000 相机没补光灯  屏幕分辨率要比IP4差些

软件方面 不用说了 APPSTORE无疑还是相当领先

但系统方面ANDRIOD比IOS更自由

IOS得越狱后 把APPLE强加上去的不自由补掉 才能相当

视频播放方面 三星对I9000的播放内核优化相当成功，连MKV都可以调用硬解

IP4只能对MP4格式进行硬解

硬解水准倒是一致的，起码X264 1080P 4.1@HL 30M没问题

i9000如果是3GS那颗A8处理器怎么可能是IP4升频的A4对手？

youku全系列视频直接硬解，什么破FLASH啊，烂货。。。。

I9000那颗是3GS的A8升级+1G频率版

A4其实就是根据三星S5PC100改进的版本 一样都是ARM A8架构  

同频下谁胜谁负还真不好说

GPU集成的SGX540MP是肯定搞定SGX535的

Apple A4 is based on the ARM processor architecture.[5] The first version released runs at 1 GHz and contains a Cortex-A8 CPU core paired with a PowerVR SGX 535 graphics processor (GPU)[3][6][7][8] built on Samsung's 45 nm process.[9]

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)[10] in collaboration with Samsung.[11] 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.[12] 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.[13][14]

The A4 processor package does not contain RAM, but supports PoP installation. The top package of the A4 used in the iPad & iPod touch[15] 4th gen contains two low-power 128 MB DDR SDRAM chips for a total of 256MB RAM. For the iPhone 4 there are two chips of 256 MB for a total of 512 MB.[16][17][18] RAM is connected to the processor using ARM's 64-bit-wide ABMA 3 AXI bus. This is twice the width of the RAM data bus used in previous ARM 11 and ARM 9 based Apple devices, to support the greater need for graphics bandwidth in the iPad.[19]


有个关键是IP4是降频到800MHZ

I9000 还是运行在1G的

资料基本都说 S5PC110和A4架构差不多吧

我理解是A4是APPLE根据S5PC100的基础上 以自己的理念进行改进

S5PC110就是三星自己继续发展的结果

两者CPU部分性能差别不会非常大

GPU 按理540胜出
