I understand that the Tegra 2 has a dual core process, but does the OS take advantage of it? From what I understand is no, what about FIFO?
since dual core is kind of like two chips working together!!! is it possible to make a Mod that would allow non- dual cores to work similarly???? like a mod that would work and make the best of it! Obviosouly wouldnt be as good as a real dual core! it was just an idea and i think it would be possible to alter the chip and make it run that way and it would be really cool
No. You'd need to redesign the whole processor. Sorry!
im new to android and ive read that the current gb 2.3.4 and below are not optimized for dual core processors.
however i also read that certain apps use the 2nd core for garbage collection and some background tasks to speed things up.
is there a list of apps that actually benefit from dual core processors like that found on my sgs2
Hello guys
I was reading history of Android and why applications weren't working good on all Android devices. I hear something its due to different versions of android and different API and that some applications work better on devices for which it was made for.
My question is: Why did some applications work better on some devices than the other? What does API has to do with it? I have read that ICS will fix this issue and that applications will not be optimized on specific device and will work on all devices becaus of API. Can someone explain me this pls?
Here is video where this guy talks about this but i don't understand it totally:

Some devices are much faster than others (single core, dual core, quad core)
Someone else pls? Cus dual core can be slower than single core if single core has application that is optimized for that hardware... Why do you think apple has only 1 phone? Cus they develop software for that particular hardware...
This is a hardware question, I have a friend who owns a Desire HD, now he goes on and on about how Single core phones are just as powerful as Dual core phones because, and this is his theory, a Dual core phone that says it is clocked at 1 GHz actually has either core clocked at 500 MHz, whereas the core in a Single core phone is clocked at 1 Ghz flat.
This just honestly seems like a frankly rubbish argument that doesn't make much sense to me, however I want to know if he's right, is there any literature out there that proves either way. Is he right? Or is he just being a boner?

long story short, he is wrong. keep in mind dual core s different from dual processor. the processor of a dual core simply allows 2 instructions to be carried out at onece adding performance to programs that have lots going on at the same time, but is still the same otherwise. They seriously help with multitasking so on android they would really help .

Correct! It allows 2 different "threads" to be computed at the same time. Your friend isn't all wrong though. Any app has to fully support dual threading. If it doesn't you will see the same performance from a 1ghz dual core phone and a 1ghz single core. Also remember the architecture of the CPU is important. In many cases a 1ghz phone may perform better than a 1.2ghz phone.

Well, almost.
Dual core means there are two independent processing units on the same chip. The chip itself operates at 1gigahertz, and that generally applies to anything on that die.
so your friend is wrong, as both cores run at 1 gig, but a lot more factors relate to actual performance.
In most cases, single core will not perform as well as a dual core at the same speed. (assuming they are the same arch)

Some dishonest Chinese sellers will do things like this.
Some places you'll see dual core NEC EV2 based tablets as "1ghz" even though it's two ~500mhz cores.
Other places you'll see a single core device deceitfully advertised as "dual core" as it includes a GPU in addition to the CPU.
They'll then add the GPU and CPU frequencies together and sell a 1.1ghz device as 1.5ghz.
(And don't get me started about seeing "Cortex A10" in the specs)
So long as we're discussing legitimate specifications, your friend is wrong
The most important thing is.... To tell your friend he is totally true.. When he revises his theory somedays later, then listen to him.

It really depends on the apps that you are running. Gingerbread does not fully support dual core processors but the Android (linux) kernel does. So if the apps you are running are written to take advantage of the extra core, they will run faster on a dual core phone. Where it does help to have an extra core is multitasking, with a dual core phone you will be able to smoothly run more apps at one time. But if you benchmark an app that only utilizes one core on both a single core and a dual core phone, the results will not automatically favor the dual core phone.
