Chip Teardown Firms Confirm iPad 2's A5 Chip Manufactured by Samsung

No Apple is not just concerned with battery life. They are concerned with the entire experience and package.
Just because these testers didn't get it to run 1 ghz. doesn't mean it can't.
As I wrote before, we all need the extra 139 to 106 or it's another 6 months of sleepless nights until the ipad 3 comes out.
Oh, did I mention NO Retina or 4LTE and HD everyplace with quad cores no buy
Needs to do my laundry too!
It does, and can, run at 1Ghz dude. Thats the point. The 894mhz number is coming from Geekbench. That program only reports the instant speed when the program opens.
Others have loaded a few apps in the background, loaded GB, and gotten 930-950mhz numbers for processor speed.
What I'm telling you is that the processor will run up to 1Ghz if needed, it's not capped at 894. All the reviewer would have to do is open and close Geekbench a few times, and it'll report diferent numbers every time, some higher.
See?
This whole thing is really silly. Do we really need to have an exact clock speed for "Fast as Hell"?
They have already proven, that with the right archetecture you can run at lower clock speeds and actually be faster than the generation before. See: Macbook Pros.

Exactly. If you could take a snapshot of the frequency when doing something like, say, running a game, we'd probably find it sitting at or near 1GHz, depending on the complexity of the game, of course. There's no reason for the CPU to be running at 1GHz when, say, opening a random app, or browsing the web. It makes more sense to throttle down the frequency and voltage in low-load situations to save battery life. Certain things just won't be any faster at 1GHz than 800MHz, for example, and there's just no reason to waste the battery in those situations.

Can go back earlier the 486sx and dx chips had a turbo function if you were old enough to remember lol
cmaier said:The A5 has 2.3x the die size of the A4 and the package is only 20% bigger. It looks like they conserved space in both the chip itself and in the iPad 2 with its weight and volume loss.
Apple is trying to get 28nm dies for the A6 vs 45 nm now, a 62% reduction. It appears the A6 may comfortably have 4 cores, a gig of memory, and integrated GPU(s) in addition to a likely 200-400 mhz bus and a 1ghz frequency range.
March 2012 iPad 3 and LTE, here we come.

When you shrink the minimum feature size by 62%, obviously the die size decreases by much less (since few features are drawn to the minimum feature size and things like metal thickness don't scale proportionally, necessitating maintaining large distances between metal to prevent parasitic coupling, etc.)
It seems to be an advanced chip that a system to adjust speed for battery consumption. Kinda like optimus thing that uses two different graphic cards: discrete vs integrated (?). This is a cool chip
Not at all like that. It just throttles the clock, like speedstep and powernow have done for a decade, and like has been done by other chips at least as far back as 1996.

Not dynamic, if I recall correctly - you had to press a button or execute a keyboard sequence? (Though there was a company that made a custom chipset for dynamic clocking based on monitoring bus accesses as a proxy for chip activity).
Each division in Samsung acts as a separate company. Samsung Mobile will go to an outside vendor for parts if Samsung Electronics (ie. RAM etc) doesn't offer best deal.
Again, imo Steve was way overboard in his taunting of his most important supplier but than he's not stupid. He knows who he should be watching as a competitor...

Hmm, I wonder if this is why my iPad 2 stutters when viewing certain videos on certain websites. And it's not the website's speed or my Internet connection as my friends 3 year-old MacBook handles them with ease. I should need the power of a MacBook to watch stupid videos on the net, should I?

What are you referring to with "this is why"? A 3 year old Macbook probably has at least a Dual 2 Ghz Core 2 Duo, which is still much more powerful than something that can go in an iPad or iPhone.
Samsung is a KOREAN company. A South Korean company. Not North Korean, the nation that's trying to illegally develop nuclear weapons.
iPad 2 production may be slowed (not that much I think) by other components made in Japan but A5 is made in South Korea.
ugh
Good thing a scanning electronic microscope is being used for such important things. Now mankind can rest easy knowing that Samsung fabricated a chip.

DID YOU really think video performance of iPad 2 would be BETTER than a MacBook? Really?
The size of the package is probably more dependent on how many pins it has and the size of the stacked RAM chips.
I think you misunderstood what newdeal wrote. He wasn't saying it's useless because it runs under 1 GHz, but that varying the speed in such a narrow range would seem have little or no benefit. At least that's what I thought.
Not illegal, just unwanted.
There is no law anyplace that forbids any nation to develop nuclear weapons.
The American "claimed" monopoly is ignored by many or the countries that don't want to listen didn't join the agreement.
BTW: I am not for ANYTHING nuclear as it is created by men and such makes it faulty!!
Proven now sadly by the Japanese disaster!
It had value beyond its scientific merit. I felt like someone handed me a print of the sonogram for my kid or something. It was a "that's cool" moment. Better than TV, dude.
