First things first: The iPad is fast. Web browsing is fast, games are fast, app switching is also fast, especially compared to the iPhone.
But if you think there are some crazy specs under the hood, you might be in for an unpleasant surprise. Doing a little coding, we’ve discovered that iPad apps only have access to 256MB of RAM and the processor thinks it is a single core (probably ARM Cortex A8) processor.
You can verify these results by building an app with the following code in Xcode:
int count ;
size_t size=sizeof(count) ;
if (sysctlbyname(“hw.memsize”,&count,&size,NULL,0)) return 1;
When using sysctl() to query the amount of memory available to the iPhone OS, the following values are reported:
|Physical (HW_PHYSMEM)||258,998,272||247 MB|
|User (HW_USERMEM)||210,284,544||200.5 MB|
