Game Development Reference
Table 2-1 summarizes the most important hardware differences that concern game
developers. The iPhone and iPod touch models are listed by generation, with the cor-
responding iPhone model suffix in brackets. Where there are two numbers for Pro-
cessor speed or memory, the first number is that of the iPhone model and the second
number is that of the iPod touch model.

As you can see, with every new generation, iOS devices usually have a faster CPU, a
more powerful graphics chip, and increased memory and screen resolution. This trend
will continue, with newer devices getting more and more powerful.
With cocos2d 2.0 you can't target the first- and second-generation devices, which make
up an increasingly smaller fraction of the iOS market. That means you're looking at a
minimum of 256MB of memory on the oldest devices you can support. However,
there's still a wide range between 256MB and 1024MB of memory, respectively a 600
MHz CPU and a Dual-Core CPU with 2x 1 GHz on the third-generation iPad.
