yeah that's true. But in all reality, if android wants to last then it can't just cover up its problems with faster processors and ignore the real issues.

The OS is by far the most important thing about our phones, if it can't keep up with the pace then sooner or later android will collapse on itself.

I just don't understand why people can't see that.
[EVO 4G General] Last-Chance:
re-read what i stated. You never witnessed it because it utilizes a single core with "decent" clock speeds. If you were to put in a single core with 2-3ghz in it, it would overheat and probably blow out the screen. (exaggeration, but you get the point.)

Well yea, i didn't mention multitasking cause i thought it was a given. And i did mention not raising clock speeds. The main point i was trying to make is the problems that arise when you raise clock speeds of a single core. They overheat, cause data loss, and consume a LOT more power, among other things.

Heat isn't as much of an issue with two cores, because each core can go idle when needed. So instead of having 1 core thats running constantly, and has the power consumption of 2ghz, you have 1 core that runs which has the power consumption of 1ghz, and have a second core in disposal if you need it (gaming and what not.)
[EVO 4G General] starplaya93:
ahh, i see what your saying....

Well good thing my EVO runs perfectly smooth on a year old processor at under 1ghz otherwise we may have some problems.
[EVO 4G General] bkrodgers:
No need to get all pissy about it. My point is simply that if dual core is ready to go, there's no reason not to use it (provided power consumption is comparable or better). The people who are designing these new processors are not the same people who need to be polishing the OS. Both can happen in parallel, and both will help the end user experience. There's no need for it to "hold up for another year or two" if something better is ready.
[EVO 4G General] Last-Chance:
lol it doesn't run fine at all. It lags. Even at a simple task of handling sense ui. With dual core processors, sense will actually be what htc wants from it, and not a bogged down lag fest.

Not only that, but it opens up a whole different type of development. The type of development that you see in the atrix. Where your phone becomes a computer.

As more cores are added, with better gpu, and better hardware, you will start to see phones like "seabird" come to reality. You stick with one core, and you will never see any development beyond the stage.
[EVO 4G General] starplaya93:
haha, sorry didn't mean to.

I get what your saying.
[EVO 4G General] mikkodd:
And a wp7 snapdragon still runs circles around the atrix LOL.. What we need is hardware acceleration point blank..
[EVO 4G General] Last-Chance:
although i do agree that android has probably the ****tiest acc there is, mainly because it's open source and the manufacturers suck **** at coding, i don't agree that it's better then atrix. But my guess is, you were exagerating.
[EVO 4G General] xHausx:
I agree sense can be laggy and that dual-cores would be a great addition to android phones but still believe single cores have potential as well. With a dedicated (and utilized) gfx chip UI performance can be improved and having faster single core performance will help with running older apps or cpu intensive games. Heat is always an issue but as long as the voltage needed is kept down it can be managed.
[EVO 4G General] novanosis85:
12ghz less power...... LOL
[EVO 4G General] tonyscha:
To play games!

But I agree with many of the posters here, increase GPUs before adding dual cores.
[EVO 4G General] xHausx:
One nice thing about dual cores though is that it should make it easier for developers to take advantage of them. Google is already implementing APIs to make use of them where with GPUs apps have to be customized for all the different types.
[EVO 4G General] Last-Chance:
didn't even see this. this must be a joke.

wake me up when you find a device with a single core 12ghz processor. hell, i don't think anyone would even attempt such a thing on a pc, let alone a phone.

Whats the point though? single cores have limits to what they can do. Why push the device beyond those limits when you can just keep increasing the cores. And once the cores are increased, you will start to see the each core being developed more and more. Just as intel did. They increased the number of cores, and then started increasing the ghz of each core. In the end they have a processor capable of handling anything you throw at it. Same thing will happen with phones. Once dual cores have their bugs worked out of them, you will start to see each core being developed more. Making them more powerful, as well as more energy efficient.

Why waste time on developing the cores now, when you can release to the public a better processor. Which in return gains money for the company for further research into developing better technology. Rather then sitting on their asses for a couple of more years, waiting to boost a single core to 2-3ghz.
[EVO 4G General] bkrodgers:
Incidentally, Honeycomb has implemented some level of GPU acceleration for the UI. Presumably the next phone-centric version (Ice Cream?) will include this as well. It's too soon to tell how well they implemented it and how much it will improve things, but at least we see evidence Google's working on it.

[EVO 4G General] xHausx:
All I'm saying is there are advantages to both. All of the cores are the same so the more they improve single core processors the better multi core chips will be as well. With smaller die sizes speed can be increased while power consumption (and heat) are kept down and as the Arm architecture advances processors will be able to do more and more with the same clock speeds. Just like how a Pentium 3 running at 2GHz can't do near as much as a single core from an i3 running at the same clock speed.
[EVO 4G General] detcup4evr:
You guys are missing the biggest reason to get to Dual or even Quad core phones with Gigs of Ram.

[EVO 4G General] ZachPA:
This is bunk, unfortunately.

I would like to call your attention to the Pentium 4. Intel touted it as the next best thing since sliced bread. The Netburst architecture, they said, would scale perfectly all the way up to 10 GHz. Inherent pipelining inefficiencies of the Netburst CPUs aside, the silicon just wasn't up to the task. Anyone who owned one of the P4-EE 3.73 GHz monsters will tell you that it took the cooling power of your average blast freezer to keep it within operating limits. Total design power for it was 145 watts.

Fast forward just one product cycle to the Core. Core 2 duo was built on a smaller process (65nm instead of 90) and was completely redesigned for significantly increased efficiency. The end result was a chip that, while clocked at half to 3/4 the speed, performed 2x the work (per core), and did it with half the energy required and heat thrown off.

The lessons learned through Intel's transition to multi-core can be applied to the ARM processors in our smartphones. While two cores always require more energy than one core, putting them together on the same die saves quite a bit, technological improvement to the architecture saves even more, and using smaller transistors and a smaller overall die size saves even more. The end result, just like the Core 2, is a smaller overall die size that is closer together and better oriented. The practical result, is arguably twice the performance with very little extra energy requirement.

So what good might dual cores be on a smartphone? For one, video conferencing could gain resolution while decreasing bitrate. Phones could capture and play back 1080 video at 30p or 60i using H.264 instead of 720 at 24p on older MPEG4 technology. Another is general power savings. If a phone has to work so hard to complete a set of tasks, with two cores it could complete them almost twice as fast, leading to drain and snappier response.

The neat thing is that Java code has been multithreaded for 10 years, so dropping a dual core into an Android phone will lead to immediate gains. And once dual cores are a reality, developers will be taking advantage of them.
[EVO 4G General] TorxT3D:
dual core?

TI already has a quad core omap5 ready for mobile applications.

technology has to progress, but at the same time you have to put some emphasis on the developers and their coding. updated mhz cant be the solution for weak programming, thats just being lazy... we all know this.

new tech brings on other supplement tech in mobile phones.

projections, 3d, virtual keyboards, kinect like interfacing, external keyboards and peripherals interfacing. The cellphons is rapidly becoming a desktop pc replacement, the industry is already trying to push tablets as being a desktop replacement where everything will be cloud based and we'll never own anything.. like cd/dvd media.

/end conspiracy rant before i go off topic.

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ and more $$$$$$$$$$$$$$$$$$$$

In an industry where your average gadget freak is always looking for the next latest and greatest thing, pushing a phone that has dual core is $$$ signs for these giant companies.

It happens every year, smartphone could be at their plateau technology wise and these people would still come up with something to sell. They would come up with the first smartphone to ever have mounted death lasers if it will get them the millions in revenue they see yearly.
[EVO 4G General] Mark_in_Tulsa:
I don't think it was mentioned yet, but what I think the biggest pro of the dual cores is the lower battery consumption.

A dual core 1G CPU can run both cores at 500 and use way less battery, and put out quite a bit less heat than 1 core CPU running at full 1GHz.

As you go up in speed the voltage goes up exponentially. So to reach the higher speeds you need more voltage.
[EVO 4G General] justinisyoung:
the main reason for dual-core processors isn't just so that companies can market it and get more money. i'm pretty sure it has to do with the evolving ARM instruction set. I don't know when ARMv8 is coming, but i think we all can be sure that it'll have lots of efficiency and power saving optimizations to it.

i think dual core plays perfectly into armv8, it'll provide huge performance gains and lots of power savings, especially since the cores won't have to work at higher clock speeds.

but, like the OP said, android is still a really new operating system, and i don't think it's too well optimized for multi-core processing. one way or another, the inner geek in us tells us that dual core is going to be awesome.
[EVO 4G General] m4xwellmurd3r:
The thing with dual cores is that they have great performance for the heat and power they use. And has quad core processors that put out 45watts of heat where a single core may put out equal or greater than for the same or less performance. Single threaded programs run the same on duals as they do on singles but threaded apps run faster on duals and multi tasking makes less of an impact on performance as singles. The big things with dials will be video recording performance if they can optimize it for dual cores, gaming if they can patch the system to off-load the work to both cores, and multi tasking. And just because a game wasn't built for dual cores doesn't mean the OS can't be optimized to take the work evenly.

[EVO 4G General] z28marols1:
The most common sense answer which has only been brought up once is that different people... hell, different companies all together are responsible for developing newer processors versus android OS. Both teams are working to make progress. One is just making progress faster than the other. You cant expect them to slow down developement on the hardware side just because the OS side can be optimized on the current hardware.
[EVO 4G General] Success100:
exactly, had harware acceleration been implemented in android, then there would be no need for damn dual core cell phones (at this moment in time at least). Hell, realize that the only dual core phones are ANDROID PHONES. Not iPhones or WP7 phones. Because the have single core setups but with hardware accel and they run circles against the top of the line Droids.

As long as they aren't related to me, I don't see any issues.

Also, forget about dualcore, tegra 2 has 10!
[EVO 4G General] SayWhat10:
I cant see why HEAT would be the main reason. Because my EVO and former phones were single core of course and I never had any heat problems. Only time I saw my friend with heat problems is when they tried to overlclock the CPU to speeds the manufacture suggests not to.

And dual-core for multitasking? I dont get it, My EVO and my last Palm pre multitasked just fine with single core.

I'm with the OP, i dont really see the super need for a dual-core processor in a cell phone. I mean all you really do is browse,text, and watch some video.Single core has been working fine for that so far.

Seems like i would need dual-core for a desktop or laptop where I can use REAL programs to do number crunching and other stuff that is really CPU intensive. I dont know of any apps in the market that really put a heavy load on my EVO's CPU.
[EVO 4G General] SayWhat10:
but why focus on the CPU to save battery? why not focus on battery technology itself? Let technology evolve and get 4500mah inside of a slim EVO battery instead

http://www.engadget.com/2010/12/08/nvidia-touts-the-benefits-of-multi-core-processors-for-smartphon/

Here's a little explanation on how dual cores will be more efficient when it comes to battery life.

I agree we need a better optimize os but the phone manufacturer's have nothing to do with that. That doesn't mean they should stop evolving. Google ****ed up by not working close with the phone manufacturer's closer from the get go therefore causing a fragmented ecosystem. Well, whatever we have to deal with it but dual core is not a gimick, it's more like an evolution for our phones.

For all the people who are afraid to evolve I feel you because I seen terminator and the matrix. First multi core handhelds than comes skynet. Damn where's my Google is skynet shirt. ;p
[EVO 4G General] xHausx:
woh woh woh, that says the dual cores have their clock speeds cut in half. that can't be right
[EVO 4G General] Mark_in_Tulsa:
It's not that they will be cut in half, but to do the same work that a single core 1ghz it only has to run both cores at half speed. They can both run up to 1ghz if they need be under hard stress, but can do the same work of a current single core 1ghz by running both cores at half speed.

[EVO 4G General] m4xwellmurd3r:
I know it may seem that this is true but it couldn't be further from the truth single threaded applications ( every Android app) would show the same performance on a dual core running at 1ghz as a single core at 1ghz. Running a dual core at 500mhz would actually have a negative impact on performance that will be highly noticeable. Look up benchmark tests on multicore pc's against similar power single core CPU. Running pi calculations would show that a single core at 1ghz would destroy a dual core at 500mhz if they ran the same architecture.

[EVO 4G General] felacio:
...duh, and neither froyo nor gingerbread have native 4G support. SENSE UI is what makes 4G work. Just because dualcore processing isn't native to froyo or GB doesn't mean the phone developer hadn't thought about it and implemented it another way..... right?..

[EVO 4G General] Product F(RED):
I have an AMD Phenom II X4 @ 3.0GHz and I can safely say that even at this point, Quad core is overkill. Dual Core will suit you fine in most situations but it's nice to be future-proofed. The reason is programs have to be written to utilize each core.
[EVO 4G General] novanosis85:
Take a 1 ghz CPU and run a program... what happens?

It runs at 1ghz.

Now take a dual core CPU at 1ghz meaning 2 cores running @ 500mhz...what happens if coded correctly?

It runs the program @ 500mhz while the other core sleeps. Saving energy and power=battery life.

When you multi task then both cores go to work. So now we run at 1 Ghz like the EVO but its smoother and faster.....
[EVO 4G General] driguez:

[EVO 4G General] gpz1100:
Are you saying a quad core processor rated at 2.8ghz has each core running at 700 mhz?
[EVO 4G General] Product F(RED):
Each core is not running at

Advertised Clock Speed/# of cores

. No offense, but that is a retarded assumption. They're all running at the same speed. What's distributed is the workload, and again, that's only if the application is written to make use of multiple threads.
[EVO 4G General] gpz1100:
Fred, what you say is correct, however I was hoping the other poster would have responded first.

Although with the newer core cpu's (i5 and i7), the cpu has the ability to clock individual cores higher than the base frequency, depending on the load. However, under very heavy load, 'turbo boost' does not go into effect. This is different than core speed being base speed/# of cores.

Look at the applications on your pc. Besides the operating system and perhaps some specialized application software (cad, photoshop, vm, games), what else is a) 64 bit, or b) designed to take advantage of multiple cores....

[EVO 4G General] xviiivx:
Funny thing is most idiots feel the same way.

As for why dual cores... it's really a dumb question. Sorry, there is such a thing. 99% of the time, a single core processor may be adequate, but do you really just want adequate?? And gaming is a big deal.. not for me, and maybe not for you, but it's a big money maker. Now imagine a game (or any app) is utilizing 100% cpu.. and then you get a phone call. If the cpu is taking it up the ass by some game, it may not be able to process that phone call in time. That's a big deal. With any smartphone, you want to have enough cpu power that there is NO chance of any core phone functionality not working due to the resource demands of other apps.

Battery life is no issue for me (I get 36 hours on a charge easily)

Build quality on my Evo is great. i got it on launch day, and it still looks brand new. I'm very rough on phones.. used have trouble making it a full year on my last several phones.

I think the quality of the Evo camera is great. Most bad pictures come from bad focus or bad settings that don't match the lighting. Sometimes it's hard to get a good shot in certain conditions, but the same can be said for $2000 cameras. Not saying the Evo's camera is in the same league as an SLR or anything, but it's good.

And then you mention crappy software. Are you talking about Android itself? If so, you are an idiot and you need to GTFO. If you're talking about apps in general, then you still need to GTFO.

[EVO 4G General] coiledwire:
We all can all understand how processing would be divided and each core does some work and overall energy is saved so its better on the battery. And people have mentioned the coding has to take advantage of having multiple cores.

I don't think its been mentioned yet in this thread but the real power savings comes from the size of the transistors. When we go from a single core CPU to a dual core, the size of the actual chip is relativity the same. The transistors are shrunk in size, allowing for more in the same area and giving us 2 cores instead of 1. Very similar to when people talk about intel's or nvidia manufacturing process going from 90nm to 45nm, they are discussing the size of the transistors. And when they shrink, they need less power to turn on and off. It goes like this:

Smaller transistors > smaller voltage to turn on > less current needed > less heat generated > better efficency > less power used.

If designed right, a 1GHz dual core CPU that's only using 1 core will be consuming less energy than a 1GHz single core CPU for any given program.

But I can understand the OP; I think my EVO works very well. It seems to be a buzz word for companies this year, trying to get more of our money. But in the end, we have a good chance that our next phone will have multiple core CPU and GPU, and we'll probably be very happy with it.
