There are a couple new things, For starters it has a new A8 processor, which is also in the iPhone 6, but since the ipod has a smaller battery than the iphones, it is a slightly dulled down version, less powerful at 1.1Ghz and 1GB of ram as opposed to its predecessor with 512mb of ram. Another new feature is the M8 motion coprocessor that efficiently your activity like walking, running and any other physical activity you do. The camera is a new 8 MegaPixel front facing camera, in which should be better than the 5th gen. Wifi connectivity and speed is much more efficient due to the new processor. Finally the a new addon to the iPod touch is the addition of the latest bluetooth hardware, 4.1. It is more reliable than the one that of the 5th gen. For those looking to keep up with technology, and the latest hardware, the new iPod Touch 6th Generation is on sale now starting at $199 for a 16GB up to $399 for 128GB.
