That dual-core A5 processor also (according to Apple, at least) gives rise to the iPhone 4S’s only unique feature: Siri.
That processing power isn’t only apparent in synthetic benchmarks: demanding 3D games such as FIFA 2012 are flawlessly smooth, even if the back of the phone does get a little toasty when the processor is pushed multitasking doesn’t trouble the processor – we had the TomTom satnav, the music player and iOS notifications running simultaneously without a hint of slowdown and there’s none of the occasional juddering witnessed on previous-generation hardware upgraded to iOS 5. This is the fastest smartphone we’ve ever seen, and by some distance. The 4S ripped through the SunSpider benchmark in 2.2 seconds – 0.4 seconds slower than our iPad 2, but a third quicker than the Galaxy S II. The full BBC homepage loaded in only 2.5 seconds – as fast as an iPad 2 running iOS 5, and a second and a half faster than the A-Listed Samsung Galaxy S II smartphone. In comes the same dual-core A5 processor that powers the iPad 2, delivering tablet-like performance in the confines of a 3.5in smartphone. This only applies to iPhones sold in the USA though, and many other countries will offer contract-free and unlocked iPhones for sale.On the inside, however, Apple has made a few significant improvements. The “no commitment/no contract” price does not mean the iPhone 4 comes unlocked, that just means it is without the two year service agreement from AT&T. The iPhone 4 price goes down dramatically when you do sign onto the two year commitment, at $199 and $299 for the 16GB and 32GB models respectively. The reason the iPhone 4 is so expensive without the two year contract commitment is that it isn’t subsidized by the carrier (in this case, AT&T), so you have to pay the full premium price to get the phone. Here is the cost chart from AT&T, you can see the price of iPhone 4 without contract in the highlighted “NO COMMITMENT” column on the right hand side. Interestingly enough, you can actually still buy the iPhone 3GS without a contract too, but it comes at a cost of $499 which makes the iPhone 4 seem like a much better deal for $100 more considering all the additional new features. This price data is directly from AT&T and applies to both the White iPhone 4 and the Black iPhone 4.
