This one is for the “techies” among you who would like to know about low-level performance specs of the iOS devices. Maybe you’ve heard of Mike Ash before? He’s a Mac programmer who writes about his profession on a weekly basis and Mike’s development blog is well worth browsing for highly interesting material. Back in March 2008 he published one of the first iPhone performance comparison for common operations.

Stuart Carnie then took this performance comparison and updated it with results for iPhone 4 and iPad, and published them in his Micro-Benchmarking blog post along with the source code. If you’re interested to learn how long it takes to perform a floating point division or a 1 MB memcopy across several iOS devices, these are the tests you were looking for.

I very much enjoy the learning process, the pushing of boundaries (mine and yours and that of technology), having the freedom to pursue whatever is on my mind, to boldly program what no one has programmed before, and to write about what I've learned. Help me help you by browsing the products in the Learn Cocos2D Store.
