I'd prefer Apple's own ARM based dual-core design over Nvidia's ARM-A9 in this device.
Does it? Eh I'm all for faster dual cores thumb.gif

The nature of my statement is an opinion. I'm saying it's better because it improves everything, whereas the quad-core is limited to improving apps which support it, and for intense multitasking.

This defies reality. It makes no sense if true, or Apple is hiding something (which I doubt since everything they do is the first time it's ever been done so it must be advertised).

Incorrect.

The nature of your statement isn't necessarily wrong, it just ignores a few important things such as POWER CONSUMPTION... If it weren't such a lost cause I could go on, but alas...

The only thing I think we can take away from these results is just how BAD the 4S really is. My 4 is garbage.

The score shouldn't be compared to Android devices, if that's what you're referring to as "makes no sense". It does look to be more than two fold better than the 4S though.

I don't agree that a quad-core will improve battery life. It's possible that it uses a similar level of power as the dual-core because it simply isn't used, but if you fully stress the quad-core it will use twice as much power as a dual-core with the same architecture and clock speed.

No. The Android and iOS results shouldn't be compared. The 4S is quite powerful and runs iOS incredibly smoothly -- it does very well in SunSpider compared to other Android devices with higher clock speeds and more cores. It also does pretty well in Peacekeeper too. The 5 is substantially faster, due mostly to improved IPC.

It is the same core architecture. How can the IPC be improved? And if it is improved, why is the score not notably higher than that of he international Galaxy S3? I haven't read anything on the GPU.

The iPhone 5 CPU isn't the same architecture as the Tegra 3 or any other ARM variant out there. It's a custom SoC built by Apple.

Guys, this is the same damn story back in June when you compare the US SGS III to the International version.

The US version beats out the international version by virtue of its dual Krait (a15-class) cores versus the International's older A9 cortex quad cores.

And since not a whole lot of apps really took any advantage of 4 cores in phones (same thing as faster i7 quads better than AMD Phenom ii hexacore due to six-core optimized apps being rarer) and the result is obvious.

We don't know what it's based off, but it's been extensively modified. You can read more about it here: http://www.anandtech.com/show/6292/iphone-5-a6-not-a15-custom-core and here: http://www.anandtech.com/show/6298/analyzing-iphone5-geekbench-results.

As I've said earlier you can't compare the scores from Android to the scores from iOS. The software interferes with the score, so it's not a fair comparison.

Besides that, the international S3 is running at 1.4GHz and has two more cores. Even the dual-core A15 only offers an improvement of 40% over the A9. With Apple doing custom architectures now they can suit the processor perfectly to iOS. According to Anand it looks like Apple have significantly overhauled the memory and cache aspect of the processor which is why it has such high memory scores and apparently that is also aiding everything else.
