	[* black] Finally! We found some serious chips.
	[* black] This iPod features the same A4 processor that's found in the [guide\|2183\|iPad] and [guide\|3130\|iPhone 4]. The Toshiba chip is very similar to the one which was present in the [guide\|2183\|iPad] in the FCC teardown, that was replaced by a Samsung one.
	[* red] The key marking of interest on the A4 processor package is *K4X2G643GE*. This is identical to the marking found on the [guide\|2183\|iPad processor\|stepid=11198], but different from the [guide\|3130\|iPhone 4 processor\|stepid=15343]. The iPad has 256 MB RAM, while the iPhone 4 features 512 MB. Unfortunately, this means that like the iPad, the new iPod Touch includes only 256 MB of RAM.
	[* blue] The NAND flash memory is now provided by Toshiba, not Samsung like that of the iPad.
-	[* orange] ~~Probably the WiFi and Bluetooth-Chip.~~
+	[* orange] Murata KM0727121 Wi-Fi module
	[* icon_note] And no, there's no RAM upgrade slot.
