How does 512Mb. of Dual-Channel RAM compare to 1Gb. of full RAM?

I am wondering on how 512Mb DDR2 dual-channel memory (RAM) stacks up to 1Gb of full DDR2 memory (RAM)? Which is better in performance wise? Aimed at LG Thrill 4G ( Optimus 3D).

512Mb DDR2 dual-channel the better

More info please

does it have a duel core processor?
i am pretty sure that the new lg phone your talking about has a duel core processor as well which allows it to process data more like a computer, basically it can do two things at once instead of one thing.

The way I understand it (or try to) is that dual-channel memory works a lot like dual-core processors. It's not as simple as just doubling the speed (like 1ghz dual core is just like 2 ghz, or 512 dual-channel memory is just like 1 gig)
It boils down to better efficiency in handling calls to the memory. Double the available roadway, traffic goes smoother. You get a faster speed (although not quite double speed), and you do so using less battery.
I might be totally wrong, but I'm sure a google search into the difference would yield tons of reading material.

yes the RAM makes it more efficient, in handleing calls to the memory, and what calls the memory? the processor. and a duel core processor allows the computer to make two calls at once, it allows it to process data faster and more efficiently because it can handle two inputs instead of one. why do you think the numbers on processors core keep going up? their way higher for computers now. and optimus is the first phone to have a duel core, i believe, unless a apple product does but i don't have a clue about their phones.

So apparently dual channel ram is nothing but two 512mb pieces of RAM both exactly identical. The advantage over single channel RAM is that programs can access two pieces of data simultaneously whereas in single channel RAM a program can only access one piece, store it, and then read the next.
Obviously you still have the limitations of having 512mb total capacity - only being able to run so many apps simultaneously, but whatever you can run simultaneously should be able to access data twice as fast.
I read somewhere that the dual channel RAM isn't fully optimized in the Froyo build that shipped with the Thrill, but the Gingerbread update right around the corner will make better use of the dual channel technology.

Now is the best time to upgrade?

Has anyone noticed the jump from 512MB of ram to 1GB? I think now is the perfect time to upgrade. The RAM combined with the processor Specs are evolving quickly. But i think the amount of ram we see in android phones will bank at 1GB for a while. Until android apps find a way to fill up that memory. Even android tablets don't fully use 1GB of the RAM they have. This means customers will be satisfied for quite a while with 1GB of ram. and in return, longer upgrade lifetime. I honestly don't see android phones with 2GB of RAM coming soon so right now would be the perfect time.
And yes, processors may evolve but i think they aren't going to be much faster or have more cores until new battery technology is found that can pack 2-3 amps per battery.
In conclusion, Phones should stay at 1GB RAM and 1.5GHz Dual-Core for a while
What do you think?

I think the phone's are very good now and way better then the 1GZ and RAM phones, but I don't think they will stop at 2cores/1.5gz. I got my SGS2, becuase it was the first smart phone that I liked and it takes alot to make me pay 600 for a phone.
I would say that Smart phone will likely start to slow down a bit like PC have soon.

That's what i forgot to mention
Buying a phone with 2GB of ram is like buying a netbook.
Soon laptops/netbooks will meet the android phone

as soon as the Quad cores hits the streets you'll most likely see 2GB RAM and newer version of ICS 4.x that will use up all that memory
our phones are turning more and more into a portable PC

Is it meaningful to have 2-cores, 4-cores, or 8-cores in the phone?

I use a phone with single core yet and I managed to buy a new phone recently, do you think it is meaningful to have 2-cores, 4-cores, or 8-cores in the phone?

with the abundance of quad cores nowadays flooding the market, developers and apps would surely catch on optimizing apps to take advantage of
4 cores. As for octa cores, if you're seriously into multi tasking or using your phone/tablet for number crunching, then 8 cores would help.

...

I think today Quad core is must, and even better if it comes with 2GB ram.
The prices keep dropping and if it fits the budget it better.
For the Octa core- I think it's the same stupid race like with the Camera MP - "look!- I have 30MP!"
Strong Quad core with 2GB ram in enough I think.

The Bigger. The Better
I had a dual core phone with half a gig of ram until a few months ago..then i switched to quad core & a gig ram..i really didnt notice much of difference..until last week, when i switched back to my old phone(as it has beautiful AMOLED screen..i just love that)..i realized that my old is quite slow n can't keep up to me speed..
so..there u go..the bigger the better..

Same thing happened in PC industry.
The software, especially video games will use every bit of your cores,no matter how many they are.

totally agree with you! :good:

I think that the Quad-Core cpu is the best, it will works perfectly for years and years (that s my opinion)
But the software optimization is even more important
Sorry for my bad english

Poor Performance on Snapdragon 1.5Ghz Krait?

I have been using my Atrix HD for a WHILE, and it has been a pain most of the time. At first I assumed it was the Processor, I quickly ruled that out with the Pantech Flex(Uses the same processor.) My second idea was the ram, which is about 808 MB, or at least that is what CPU-Z is detecting. Even when the phone is idle it only has about 45% ram free to use. I am even running Cyanogenmod 11 rom. Most apps are unresponsive as well, even the System UI.
Basically, Why is the Atrix HD slow, and unresponsive? The Pantech Flex is the same phone, and it plays games like Asphalt 8, ShadowguneadZone,Dead Trigger 1 & 2 and I experience little to no lag at all.
I am getting a new Samsung Galaxy SIII:victory:, hopefully the 2GBs of ram will improve my experience.

Don't use task killers. Keeping apps running in memory means they're quick to bring up again, since they're still running. Closing them and/or freeing up RAM with a task killer means they have to reload from storage each time.

The Atrix HD has nearly double the pixels to push.1280x720 vs 960x540 = 921600 pixels vs 518400. With equal CPU/GPU/RAM, the one with the few pixels to push will have the smoother performance and faster framerate.

Why an S3? Yes, the extra RAM will help, but it's still the same CPU/GPU. If you're on a serious budget a Nexus 4 will give you much better performance than an S3 (although you're stuck with 8/16GB). If you can afford a bit more, there's a seller on eBay that has brand new AT&T LG G2s for $250, and that's a performance vs price ratio that can hardly be beat. There's also some Optimius G's brand new for $170-180, which is basically a Nexus 4 with LG software and a microSD card slot, and that's a pretty good deal too.

8GB or 16GB - Does it really matter?

There seems to be some good deals around on the 8GB model at the moment but not for the 16GB. Obviously more memory is always better - the phone it will replace is the Samsung S2 which has been memory bound, however with an SD slot in the Moto G will it actually be an issue having less onboard?
I know that Android M has ability to use SD cards for system storage and that it hasn't been released yet. This can only be a few weeks away?
At near half the price of the 16GB, is the 8GB a much better purchase?

What about the difference in RAM? 2gb better than 1.

Oh, I hadn't appreciated that - thanks for pointing that out....I guess it could be a bit of a dog without enough RAM?

Size does matters my friends....

My 1GB RAM model is pretty great for the price. Battery life is fantastic, however having the low_ram flag enabled in build.prop is a bit of an issue for some apps.

1 GB RAM vs. 2 GB RAM really does make a difference.
Initially I bought the 1 GB Moto G, as here in Germany the 2 GB version is only available with a hefty price tag via Moto Maker. Later on replaced this with a 2 GB Moto G ordered from Amazon Italy (less expensive than the 1 GB version here in Germany ).
At first glance performance is pretty much the same.
Though the 2 GB version can keep more apps in memory in the background.
With 1 GB I had sometimes the problem that Android did kill e.g. the Music player running in the background while surfing the web with Google Chrome (Chrome is a huge memory hog).
So far I didn't have such issues with the 2 GB Moto G.
Also the 2 GB version is for sure more future proof. Which is important if you are not willing to buy a new phone every 1-2 years.
My previous phone was a Samsung Galaxy S Plus. Which was perfectly ok for my everyday tasks since I think back in 2011 until a few weeks ago - thanks to good custom ROM support.
What made me exchange it for the Moto G in the end was the performance bottle neck caused by the lack of free memory (512 MB) and not the CPU or the rest of the hardware.
So I hope thanks to 2 GB RAM the Moto G will last me at least as long as my old Galaxy S Plus.

It doesn't really matter if you picked up a high speed SD card and use Marshmallow. I've seen no problems with the external SD -> internal SD feature.
About the RAM difference, you should use virtualized RAM as soon as you can if you're using the 1 GB model.

I only paid the extra because of that extra 1gb of ram. Believe me...it matters!! If you want to keep app updates coming, xposed modules running, etc etc....you need that extra ram. This is a great phone out of the box, but if you're here and you're asking, you're probably not leaving it untouched

I've got the 1gb model, and never found myself wanting more. Of course I keep my use simple. But for what I do, its more than enough.

My previous device had 1 GB of RAM. In my opinion, the 2 GB is definitely worth the extra cash. The multitasking difference is night and day to me, and I no longer have to worry about what is running in the background slowing the device down. I do a fair amount of gaming on Android as well, it is nice to sit back and play a game with Pandora or similar running without the OS killing it to free up memory for the game.

The 2gb makes it much more future proof. I have the 2gb version and I have never had to close any app most of the time. With 1gb of ram, you will have to close apps much more often making multi tasking a little more difficult.

What is 'virtualized ram?'
I'm in the boat with the 1 giggers and I'm curious how to do that.
I mainly use this phone for office tasks and it performs incredibly, but hey! An increase is an increase right?
Also curious about the posters response about low_ram flag.

In Kernel Adiutor there is a Virtual Memory section and if you scroll down all the way there is a slider called Z-RAM. You can adjust the size of the memory there. Instead of using a swap file this compresses the RAM, making room for extra storage. But it has downsides, the extra processing required to compress the RAM eats the battery at a slightly faster rate.
I haven't heard about the low_ram flag, I'm afraid that I cannot tell you about it.

Thanks! It passed me honestly because I haven't messed around with any kernels since my n5. Usually just flash and let it fly lol I'm gonna check it out now though, appreciate the push!
