TechnoBuffalo published a comparative video featuring the performance of the new iPod touch against the iPhone 4.
As a reminder, the new iPod touch integrates the same processor as the iPhone 4 (Apple A4) but has 2256MB of RAM against double for the new iPhone. At the sight of this video, we can only note that the performance of the fourth generation of the iPod touch is very satisfactory or equivalent to the iPhone 4 in many situations. The dual RAM capacity for the new iPhone, however, allows it to be more flexible when many applications are launched, especially in the background. As a reminder, the iPod touch also incorporates a Retina-type LCD screen.
We discuss it on the forum.
