Six Generations of iPhones: Performance Compared
Section by Anand Shimpi
Cross platform smartphone benchmarks are interesting, but they do come with their own sets of issues. Before we get to that analysis however, let's look at how the iPhone's performance has improved over the past six generations. Luckily Brian has a set of all of the iPhones so he was able to run a few tests on all of the devices, each running the latest supported OS.
We'll start with SunSpider 0.9.1, our trusty javascript performance test:
The transition from iPhone to iPhone 3G shows you just how much additional performance you can squeeze out of simply a software change. There's likely even more that could be squeezed out of that ARM11 platform, unfortunately newer versions of Safari/iOS aren't supported on the iPhone 3G so we're left with a runtime that's around 37x the length of a single run on the iPhone 5.
The rest of the devices support and run iOS 6, so we're at least on a level software playing field. The performance boost from one generation to the next is quite significant still. Going by this chart alone, the best balance of minimal upgrades and maximum perceived improvement would be from the original iPhone to the 3GS then again from the 3GS to the 5.
The BrowserMark results tell a similar story. The jump from the ARM11 based iPhone/iPhone 3G to the 3GS running iOS 6 is huge. Both the 4S and 5 offer doublings in performance, albeit for different reasons. The 4S delivered a doubling thanks to a doubling of core count and a move to the Cortex A9, while the iPhone 5 doubled performance through a much higher clock speed and microarchitectural improvements.
Finally we have Geekbench 2, which only runs on the iOS 6 supported devices so we say goodbye to the original iPhone and iPhone 3G:
None of the jumps looks as dramatic as the move to the iPhone 5, but we already know why. The Swift CPU architecture does a great job improving memory performance, which shows up quite nicely in a lot of the Geekbench 2 subtests.
On the PC side we often talk about 20% performance improvements from one generation to the next being significant. It's clear that the mobile SoC space is still operating along a hyper Moore's Law curve. The rate of progress will eventually slow down, but I don't see that happening for at least another couple generations. The move to ARM's Cortex A15 will be met with another increase in performance (and a similarly large set of power challenges), and whatever comes next will push smartphones into a completely new category of performance.

'Right, so if you have good vision, like I do, then at a foot away, you can see those pixels.'If you can see that then you would also be capable of observing that the SG3 doesn't have full pixels, it uses a PenTile display which overall has fewer sub pixels over a greater area than the iPhone 5 screen, making it both absolutely lower quality and relatively lower quality per area.

You can discern individual pixels on an iPhone 5 display?Lies.

Im sure this guy said the same thing when the 4 came out...3.5 was "big enough"Just watch when apple adds an even bigger screen he will be saying it is "perfect"
The problem with iSheeps is that they need to get out there and actually use a different phone from a different ecosystem for a month, then switch back.
Apple's devices are well built and tightly integrated, but there are serious shortcomings, drawbacks, and flaws that you will notice once you return to the platform.
That said,
Personally i purchase apple products due to the insanely high resale value, which allows me to keep up with new gear on a yearly basis for a reasonable price.

"iSheeps"? Must you resort to name calling to make your point?rarson - Thursday, October 18, 2012 - link
"Personally i purchase apple products due to the insanely high resale value, which allows me to keep up with new gear on a yearly basis for a reasonable price."I don't see it. Maybe if you buy the newest thing as soon as it comes out and sell your old last-gen device that most people are still happy with, then you're selling it for a decent amount, but you're still spending way more money than any reasonable person would. There's absolutely no monetary argument to buy Apple products, because if money is your concern, then you shouldn't be buying them in the first place.
Apple's phone prices are much closer in line with their hardware; for laptops and desktops, the resale value argument goes WAY out of whack.

I bought an early 2011 MBP last year for $2650 AUD. got a high res screen option etc. I heard rumours of the retina model and sold it just before the 12 months was up so the new purchaser still had a little warranty me could buy AppleCare if they wished. I sold it for $2300 AUD. This means I lost $350 over the year, it cost me $350 to have that machine for a year. I didn't buy AppleCare ($429 AUD) either.The retina model came out, and retailed for $2499 AUD
I've been doing this since my first Mac, in 2006. I can't believe the crazy used prices on Macs especially if they are still current model and about a year old. I pay about $300-$400 a year to have the latest and greatest and a machine that is always in warranty. If I bought a cheap PC notebook for $400 I'd be suffering with an underpowered plastic machine with little ram, no SSD, and it might last more than a year but I wouldn't be happy with it anyway. Each to their own. I could never stay current with PCs because a year later the system was next to worthless, even if I'd put a $1000 video card in it at the time. (I now, reluctantly, game on consoles or a little in bootcamp)

"there are serious shortcomings, drawbacks, and flaws"So what are they?
The problem with trolls is that they just spout bull.

Apple refuses to pull its head out of its ass or LEARN. One profound impediment to making iOS devices useful is Apple's ridiculous fear, which you can see in its crippled SDK. One example: the lack of developer access to the dock port.But then there is just plain stupidity. There's no excuse for bullshit like this: http://goldmanosi.blogspot.com/2012/06/will-apple-...

Um, when someone calls me and I miss the call, iPhone shows a missed call. Then my carrier (Telstra) sends me a text message "You have a missed call from 0412xxxxxx" then "Please call 101 you have 1 new voicemail(s)"I get multiple alerts for both those SMS messages.

Why going all the way in calling people that like apple products as sheeps?I think you should accept the fact that some people like small phones, and maybe like small smartphones, which neither iphone5 or sgs3 are.
From my perspective iphone 4/4s screen was maximum I would go with something called phone into my pocket, but I do not, instead finding xperia mini great sized, although too thick.
My point, why would we have to considere as progress only bigger screen phones as such, we do have plenty of tablets to pick from for that usage?
