[QUOTE=PyroCF;37698023]If Google would write Android in Native code it would be a hell of a lot better.
Also keep an eye for Samsung's A15 SoC the Exynos 5, looks pretty damn promising.[/QUOTE]
As I recall Google's Java VM isn't nearly as optimized as it could be; I'd expect to see improvements to it in subsequent versions of android. Project butter did some groundwork but it's just triple buffering and some prediction as to what you want to do, optimizing the underlying core will really help.
Not impressed.
It's doing what it is supposed to do.

There's no such thing as "Google's Java VM"; you mean "Dalvik VM", something completely different from that Oracle product ;-)
I wonder if Dalvik does or could do JIT.
EDIT: Hmm, Dalvik does do JIT as of Froyo.

[QUOTE=barttool;37699236]it's called software optimization. When you're building an OS JUST for one specific processor, then you can get much more power out of it because you can optimize everything to work for that specific processor.
It is the same case with OSX, which runs much faster even in older mac models with older processors than Windows, because it is optimized for those specific processors.
Same case with consoles, that despite the fact that their hardware is old as shit, they can still deliver rather good graphics because devs can work on that specific set of hardware.
Same case with windows phone, that only allows OEMs to use an specific processor, therefore you have 3 year old processors running smoother than your latest high-end android phone (OS performance wise)[/QUOTE]
Is android available as source so that you can compile it for your phone specifically? That should provide a minor performance boost, but nothing is a substitute for actually writing for the hardware specifically.

I think there are a few parts that are closed source, but you can access source for most of it.

OS optimization is not the explanation for the score. Optimization is a cool thing, and you can get some extra performance from doing it, but you should be looking elsewhere (in the thread, as it has been explained multiple times) for you answer.
They should benchnark the miui m2 IM sure it outperforms any device.

Yes, the software for the system 'Android' itself is open source, however, for the most part the drivers are not.

A dual core outperforming a quadcore, that's good engineering and OS optimization[/QUOTE]
This is still occasionally true on desktops as well. A very high powered dual-core will out-perform a quad core because most applications still are not programmed to utilize all four cores
Here's a benchmark of the dual-core krait SGSIII against the Exynos 4 version: [url]http://www.gsmarena.com/samsung_galaxy_s_iii_us_version-review-774p4.php[/url]
You'll see that the dual-core is actually outperforming the Exynos 4 in many cases, spare for the GPU-heavy benchmarks (which has little to do with CPU performance). The Apple A6 is like the Krait a hybrid, and as you can see, they perform very similarly - though the Krait [I]is[/I] running at a higher clock speed. The quad-core Krait phones coming out this month will outperform the A6 by quite a margin, and when the real A15 SoCs come out, it'll be no contest at all. This is very cool, but it's not as ground-breaking as it's toted.

A lot of applications will never be multithreaded. To use an example I've used dozens of times before, a 16 threaded notepad is just 15 different levels of moronic. The performance boost is essentially nonexistent, in some cases may actually cost performance, and the memory and overall processor use increases by an enormous margin.
Quad vs Dual core chips, all other factors like architecture and clock rate being equal, will only matter for some tasks, or when you are attempting to handle large numbers of tasks at once. Most of these tasks are things that you generally don't want to be running on a phone anyways because of battery life.
This is related to why most mobile processors have some option to turn off individual cores on the fly to reduce power consumption considerably.
Meh, I'm still happy with my Moto Atrix, it was one of the fastest when it came out, and mine hasn't slowed down since!
The battery life however...
The general rule is that multithreading helps with computation, but not memory access. The RAM is still serial.

I'm no expert on this shit :v:
On my Asus tf300 I just benched 1689. I don't know where they are getting their numbers from.
the lack of A6 chip in the new [b]iPod Touch[/b] irritates me, especially since I'll only ever afford the new [b]iPod Touch[/b] for the foreseeable future.
i've never heard of this itouch product you speak about
however, the new iPod touch would be even better if it had an A6 chip, though no really necessary.

oh no he does not want to say the entire name when everybody knows what he is talking about.
Think I say Asus EEE Transformer Pad TF300T every time?

sorry, your majesty
although what is this "no really necessary" you speak of?
however, I definitely wouldn't say the A6 chip is unnecessary, especially with theses massive performance boosts.
[QUOTE=SSBMX;37703604]oh no he does not want to say the entire name when everybody knows what he is talking about.

Well, it has happened before.

Honestly, I'm excited for the iPhone 5. You have to give credit to Apple on the improvements they've made from the 4s.
Although the 4s has OK battery life it's shit compared to the other iPhones, and it burns really fast. Sometimes you don't even have time to notice the battery bar go down.
Also I'm glad to see they brought back the metal backing cause I took my otterbox off one day and accidentally dropped the phone, now I have a huge crack along the back.
I want to know what the thickness limit will be on phones.
[editline]18th September 2012[/editline]
Personally I would like it to be 5mm
And there we go, quad-core Krait benchmarks: [url]http://www.gsmarena.com/lg_optimus_g-review-814p4.php[/url]
There is no doubt about the fact that some very talented people work hard on Apple's products.
Shame that the company itself is terrible so I can't see myself buying anything from them.
I like this, but with iOS it's so damn smooth anyway this won't make any difference, unless you play the rear view mirror car driving game
It took android a damn long time to get anywhere as smooth. Before that it felt really clunky to use. The only reason I didn't get android in the past.
Goophone FTW

Well of course you have battery -- if you actually have friends, or a girlfriend, and text people that usually kills the battery.
