Apple's iPad 2,4 also uses 32nm A5 S5L8942 SoC
 

Through Chipworks, we recently learned that Apple's revised A5 SoC (S5L8942) is built on a 32nm Samsung HKMG process. While its presence in the Apple TV (3rd generation) which we've reviewed and inspected is an absolute certainty, up until recently it hasn't been as common knowledge that the iPad 2,4 ($399 cost reduced Wi-Fi model) also contains the same S5L8942 SoC but with both A9 cores enabled, as opposed to the single core A9 configuration of the Apple TV 3.

To quell any possible naysayers, I grabbed the "iPad2,4_5.1_9B176_Restore" image a while ago, opened it up, and inspected the kernelcache for references to S5L8942, which there are. Note that the iPad2,4 is k93aap, there are numerous other references to S5L8942 elsewhere, including the buildmanifest plist, eg "Firmware/all_flash/all_flash.k93aap.production/glyphcharging.s5l8942x.img3." There's no question about S5L8942 (A5R2) being inside iPad2,4.
