Read more about the new iPad
UPDATED: Apple's pretty good about specs. It displays most of them clearly on its website. But it left out a few of the new iPad 3's juiciest bits. Want to know the full story?
We already knew the new iPad battery is bigger than that of the iPad 2, but the actual capacity isn't seen on the tablet's page. We're not sure why Apple wouldn't want to show if off, though, because the thing is ruddy enormous.
It's a 11,666mAh capacity unit, where the iPad 2 had a 6930mAh model. That's an almost 70 percent increase. Those complaining about the 0.6mm extra thickness of the new iPad should probably pipe down at this point.
It does beg another question, though. If the quad-core GPU and 4G LTE connectivity are such astonishing power drains, how hot is the thing going to get under strain? If the iPad starts setting houses on fire, it could be the PR gaffe of the century.
The A5x processor
From Apple's presentation on the new iPad alone, you might think the A5x is a "quad-core" CPU. However, it's actually a bit more complicated. It's a SoC (system on chip) that combines a dual-core CPU and a quad-core GPU. As a very reductive explanation, the CPU crunches the numbers in Excel while the GPU throws out the pixels in 'yer video games.
Apple also didn't let slip about the processor speed. Its CPU has a 1.5GHz clock speed. That's up from a 1GHz model in the iPad 2. In summary it's a very significant upgrade you might not at first appreciate from clocking the "dual-core" part.
UPDATE: recent benchmarks suggest the new iPad processor is 1GHz, like the iPad 2, rather than 1.5GHz. However, the GPU is still significantly more powerful.
RAM is the memory that greases the operation of any system software. The iPad 2 uses 512MB , but the new iPad has a whopping 1GB.
This huge increase in RAM suggests Apple may have some big plans for iOS - things that require a little more power. It also suggests that iOS will one day run like a dog on the iPad and iPad 2. Oh well, I guess we'll all have to buy a "new" iPad then, eh?
Although the 3G/4G version of the iPad is certified for use worldwide with 3G, the 4G chip is designed for use with North American networks. The rest of the world that uses slightly different standards will be stuffed.
However, as there's no 4G network in the UK to use anyway, who cares?
The new iPad will be available from 16 March.
