Yesterday, we reported that a teardown of 3rd gen. Apple TV has revealed that it sports a newer A5 chip which contains a dual core processor, but with only one core operating. So, the folks at AnandTech couldn’t resist but check out Apple’s cost reduced 16GB iPad 2 (CDN $419) for the same processor and looks like they were right. The cheaper iPad, a.k.a iPad 2,4, does sport the same 32nm A5 chip but with both cores enabled, as opposed to the single core configuration of the Apple TV 3.
Detailing from the source:
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.
The end result is that if you’re an iPad2,4 owner, you’ve got Samsung 32nm HKMG silicon inside. There’s no doubt about iPad2,4 being out and in the wild either, as a number of geekbench 2 runs have popped up since release on their online result browser, which I’ve been watching like a hawk. As an aside, performance between the S5L8942 (A5R2) and S5L8940 (A5) is virtually unchanged between the iPad2,4 and iPad2,1 if you compare runs on the result browser.
Now the interesting question is whether iPad2,4 owners have improved battery life compared to those with iPad2,1 (WiFi)?
