In a revealing story at the Touch Arcade, research has shown that the iPod Touch 2G sports a faster CPU clock speed and possibly some GPU tweaks that make it not only superior to the previous generation iPod Touch, but also the iPhone 3G.
“The most clear difference is that fact that the iPod Touch’s processor was quietly boosted to 532MHz (up from 412MHz) with the 2nd generation model introduced in September. Meanwhile, the iPhone 3G, Original iPhone and 1st Generation iPod Touch continue to run at the original 412MHz.” says the report on Touch Arcade.
Backing up a bit, we find that the iPhone’s ARM processor is actually capable of a speed of 620Mhz, but is downclocked to 412Mhz. This is most possibly to reduce heating and battery life issues. While we have no idea whether Apple will increase the clock speed via a firmware update or as a brand new device, we have one instance where Apple has pushed the Mhz via a firmware update.
Apple better do something about this, as developers are having a hard time developing games for the varied configurations. Tests have shown that there are performance differences between even those with the same clock speed.
“Where we can easily display two 1500 polygon tennis players with 32 bones each on the iPod touch 2G and maintain fast and fluid game play, the original iPod touch just chokes, and in some instances so do the iPhones.” Thomas Fessler, a game developer, reports to Touch Arcade.
To all those who have been wondering why their friend’s iPod Touch 2G provides better frame-rates than their iPhone, know that Apple has been discriminating under the hood. Well, at least this will please those users who are bummed about the missing Street View on the iPod Touch.
