How about this:

Another think noticed....

Why isnt technical preview (released last week) of QTSDK include Meego Support? Is thios cause Meego is dead?

Hell No I am really bad person spreding rumors like this I guess there will be tweets about this soon :-O

haha b/c today MeeGo got a updated SDK with added Windows 7/XP support

= different manufactors, different ways the CPU works.

Same goes for dualcore vs singelcore. If the OS isn't optimized for dualcore maybe singlecore infact is faster.

Also what I meant was even if the CPU SUPPORTS xxx feature it doesnt always means the core OS is ready to support it but still people beleive it cause the "specs" says soo.
Well the Snapdragon uses basically the same core as the Cortex A8. The thing why such a Qualcomm at 800MHz may be slower than a "standard" Cortex A8 at 600MHz is because the Snapdragon uses a crappier GPU than the A8. So at pure CPU power the Snapdragon at 800MHz would be faster but when you benchmark a combination of CPU and GPU intensive tasks the opposite may be the case.

The other thing is: If an OS is not "dual-core optimized" - meaning it simply can't switch tasks to one or the other core and schedule accordingly - it wouldn't make any sense to produce such a device with such an OS, right?
And even if the OS could use just one core of a dual-core CPU it wouldn't be any slower than the single-core variant of the same CPU at the same clock, like you're stating.
Meego, because it's using the Linux Kernel, is able of using multiple CPU cores, so it definately could make use of 2 cores instead of 1.

The other thing is (and that's what you were probably thinking of): If a program isn't optimized for multiple cores, which means it's making usage of single and serially flowing threads and isn't able to do anything in parallel, than it really isn't any faster on a dual-core CPU. That's the case for example older games, where they aren't running any faster on dual-cores, because they're utilizing just 1 core of the CPU. But the whole OS will still be able to do more work at the same time: For example you can do other things that are utilizing the second core and it won't slow things down running on the first core.

So even if programs aren't optimized for running on multiple cores, the OS can still benefit from such a processor and so can the user .

[begin sarcasm:]

We all should be just happy: Nokia has shifted their timeline from "release product - give users 1-2 firmware updates - scrap product" to "design product - scrap product"

I mean, how can I be upset about a device not receiving official support, when said device is scrapped before I even get one? Perfect customer relations strategy from Nokia, bravo!

[end sarcasm]

If it was up to the brilliant minds of TMO, we'd have an N9 in our hands already with a discussion how to OC it to 2.5GHz... Alas, it is in the hands of love/hate-Nokia, so we wait.

Another rumour was that N9 (***i) was canned because it was very late - a possible reason it was so late was that it was rumoured that something in the graphics subsystem was completely respec'd leading to a massive re-design of the UI.

If it is the case that symbian has still managed to control Nokia's future then I can't see Nokia surviving the next two years. Symbian has poisoned nokia's future and killed all progress. It was disfunctional years ago and instead of culling it they positively rejoiced in turning everyone into a engineer inside the symbian organisation.

That said if one of the particular projects I've seen in Nokia survives as a small ninja team and doesn't get bloated with bureaucratic leeches that seem to survive in Nokias warm socialist ideal, then maybe they will actually deliver a compelling UI.

No. It uses the same ARMv7 instruction set, but the core design is Qualcomm's own creation.

OK, because hype is almost tangible, let's get a few things (marketing) straight.

* 1080p encoding and decoding without consuming all the cpu cycles
No self-respecting ARM does on-CPU video decoding. Even the much stronger dual-atoms had difficulty keeping up without dedicated video hardware. Case in point - the N8 has a weaker CPU than the N900 and yet kicks it's butt when it comes to video de/encoding.

* Multitasking will be smooth and less time to do tasks
More often than not hiccups are caused by disk IO and/or memory bottlenecks. Having 2 CPUs does not *inherently* give you any more smoothness, ditto for tasks.

* gaming will be on a different level
I doubt it. In what way are games limited by the CPU nowadays (except for emulators/simulators) ? Games are graphics hardware and memory bound.

* smoother GUI transitions
Transitions have nothing to do with number of cores whatsoever.

[quote]* better batter usage (in theory, two horses can climb steeper hill than one horse)[quote]

That one CAN be true. In reality I would expect the gains to even out the losses when both cores are burning juice.

The bottom line is that *today*, the benefits of dual core are mostly marketing, as clocks have topped out, megapixels too, now we will play the core count game, regardless of real-world results.

So how many horses does it take to climb a 90 degrees 'hill'?

Oddly enough this must some moores law going on in the mobile chip arena. I mean to really make an incremental leap, this chip manufacturers should of made some dual core 600MHz-800MHz chips, as the speed would improve and battery consumption will reduce since processor loads can be split and done quicker. But 1.2GHz dual and now I hear Quads is insane I am really concerned about battery life here.

As for Nokia, honestly this silence is eery even for Nokia. I hope to see some good products, but honestly with the track record they have had for the past 5-8 years I wouldn't be suprised about such rumours as the N9 cancellation or MeeGo being canned or WinMo7. I just can't believe the Titanic of the mobile world was sunk not by the iPhone but rather through sheer incompetence of the management body. Every move has been wrong, every decision has been draconian and all were half measures. Nokia at the end of the day was not hungry enough ... see what Palm did when they had no more options (granted they still failed because the sweet WebOS was not paired with the right Hardware for the second, and third iteration. Look at the turnaround Moto has made. Nokia hasn't commited to compete, this is the problem. If every quarter they still are number 1 albeit losing market share ... then they are still complacent.

Wait until you see Q4 results from 2010. Symbian and Nokia dead? not so much.
