Just heard out of blue and read somewhere on the forums that some companies are planning on dualcore.
Just curious how true is that?
dude.. wrong place to ask this.
But... Yea its true. There are some 'dual core' processors out there now, but its mainly one GPU processor and a CPU processor.
Ive read somewhere that Qualcom are planning on makin a true dual core cpu ;-)
I think that they should hold off. 1Ghz is fast enough. We have not meet 2Ghz yet. In my opinion a dual core phone would be too powerful!!! But in many cases it would be a nice option. Everything would be instant and they would have to increase the nand and ram speed. Imagine, a phone with 0 lag with no matter what you do.....
think of the battery life with 2GHz processor!

They would probably find something more energy efficient - like the Intel N450 processors as opposed to its predecessors.

the processor behind every dual core chipset.
samsung announced releasing a 1ghz dual core processor for early 2011 , as well as qualcomm started shipping its 1.2 ghz dual core processor , but not yet applied on phones but is said to be in early 2011 too, but the qualcomm 1.5 was delayed for the end of 2011 , that is all the info i collected about dualcore processors
I own this 2 beast and I also quit confusing to compare this smartphone which is the best one. I like the speed of O2X, but dislike it ui or interface if compare to DHD htc sense. I also like DHD aluminum body more than O2X plastic. So, what do you think guys? which one is better?

Any one? just to know your opinion.

is there a massive speed difference?
Well the biggest difference is probably that Dual Core processor of the O2X (2 x 1GHz) while the DHD only has a single core (also 1GHz).
The main camera is similar, but the O2X is capable of 1080p video recording AND additionally has a front faced camera for video calls.
It has also got more internal storage (8GB) and a slightly better battery (1500 mAH)
So yeah, I would say that the O2X is better than the DHD.

yeh but it has an extremely buggy ui. the speed test show it beats the dhd in web browsing by 1-2 seconds. also some benchmark test show the dhd scoring higher.
also the dualcore phones dont have 2x 1GHz cpu... the total speed is 1ghz
so its (2x 500mhz) this is more efficient than single core.

Say what?!
A 1ghz dual core processor is not 2 processors running at 500mhz!!! It is a single CPU with 2 cores capable of processing separate threads. It runs at 1ghz and technically it is like 2 1ghz processors operating in tandem.
Shoot whoever is spreading the above misinformation lol.

He is definitely right.
You can't just add the speeds of two seperate cores up. The dual core runs at 2 @ 1Ghz. That's like two seperate CPUs, each with a clock speed of 1Ghz. So it is NOT 2 Ghz CPU but rather 2 processors @ 1Ghz. It may sound similar, but it makes a huge difference (for further detail you should look into how a processor works and what threads are).

Just google about dual core vs single core.
You will find info where dual core freq is same as single core. The only different is that dual core is way better when doing multitasking (avoid hang or jitter) and not to say double speed but can say nearly double speed.

Ok guys, it is clearly in term of hardware O2X is the winner. But how about its ui? software? And its unibody design? any opinion i do appreciate.
Thanks.

Im not an expert but correct me if im wrong.
1 CPU with 2 core. Each core have 1 ghz freq. 1 core to do 1 task, another core to do another task. Meaning freq each core still 1 ghz but since its have dual core it can do both task at the same time. More quick than a single core. If we compare to single core with 2 ghz, it can only do task 1 at a time. In term of speed i think dual core 1 ghz should be nearly the same as 1 core 2 ghz. I also read some where saying single core 2 ghz consume more power than dual core 1 ghz.
Just my 2 cent.

I'm 100% sure. Here's a brief history of multi core processors for those who are interested.
In the late 90's and early 000's, processor speed was constantly on the rise. Manufacturers were trying to out-do each other in regards to who had the fastest clock speed.
The way clock speed increases is by actually shrinking the microarchitecture (Semi-Conductors) of the processor, which leads to faster data transfer/processing rates. There was a pattern involved where each new generation of chip architecture yielded almost twice the clock speed of the past generation. However, as processor architecture grew smaller and smaller, eventually we approached a stage where physically, using current materials and manufacturing processes, a limit had been reached. It wasn't possible to continue shrinking the size of the processor, so logically, the next step was to integrate multiple cores on a single chip. This was the birth of the multicore processor.
The way a multicore processor works is by utilising multiple processor cores on a single chip. This way, instead of a higher clock speed, you have multiple cores running at the same speed, 'sharing' the workload. So, a 1ghz Dual Core Processor is a single chip, with 2 cores both clocked at 1ghz. A 3ghz Quad Core Processor is a single chip, with 4 cores all clocked at 3ghz.
This all sounds wonderful, but for a multicore processor to be used efficiently, it requires software to be multithreaded. This is where you have to question the use of dual core processors in smartphones, as none of the applications or the OS utilise multiple threads! So really, as it stands, you'll struggle to see truly improved performance from dual core handsets.
This will all change in the future. Android 2.4 will support dual cores by default and I'm guessing most software will start to aswell.
Anway, hope this was interesting for those wondering how dual core processors work and about clock speed etc.

Well i have both phones now... i missed the sence weather and clock from DHD but fancy widget fixed that. O2x still has a few bugs ie black screen and auto reboots but i only had 1 bs a 2 reboots in 2 weeks now . games work better on o2x also with normal lock screen o2x is snapper all over at stock than a oc to 1.2 ghz DHD but the best part is the real HDMI out (no need for a ps3) but i will keep both phones

It will always show as quad core as its only going to be using one set of quads at a time. Either the big or LITTLE set, the change between them will be seemless.

ì got it..
Which one do i get!?!?!?! I cant decide... help me!
I don't think i will get 4G anytime soon (too expensive on my network) so i really don't know which version to get? which on has better battery life etc..
pls help, detailed answers will be really helpful. I need to make a decision before Friday.
I suggest, go for S4 I9500 Octa-Core. Check my detailed previous reply to a similar question.

I would recommend the quad core. I have the octa cor myself but the quad core is said to have better battery life and it has LOTS of custom roms
Octa core is not octa at all. It's rather dual quad. Eight cores never work at once in this cpu. This is so called big little architecture designed to save battery while keeping high cpu power. Looks like this attempt failed for now. Take a look at gsm arena comparison.
IMHO 9505 is way better deal.

I dont think it failed entirely. If the exynos 1.6GHz quad can beat the 1.9GHz quad Krait in terms of performance than that's a feat in itself.
Get the one which is officially sold in your country.

I have the octa core and i love it! Although I would add that i do not have the quad core to compare with. Both are great.
In the end it all boils down to LTE or not to LTE. I chose not to. For me, anything above 3Mbps is quite handy. And i get 6Mbps+ approx on my AT&T prepaid HSPA+.

http://www.gsmarena.com/samsung_galaxy_s4_i9500_vs_i9505-review-930p6.php
"Performance-wise, the octa-core Exynos has a slight advantage, but that's not because of the higher number of cores. You have got to remember that only a single set of four cores is active at a any single time - either the power-sipping Cortex A7's or the number-crunching Cortex A15's.
It is evident from our tests however, that the Exynos version of the Galaxy S4 is not much more powerful than the Snapdragon 600. Furthermore, the battery life performance of the Exynos-touting variant is consistently worse than the one by the Snapdragon 600 version."
Which is why i picked i9505. Almost no difference in speed but big difference in battery. My i9505 lasts almost 2 days sometimes.
Why GT-I9505 is faster than GT-I9500 if it's a quad core? Apparently I'm lucky enough that GT-I9505 is even cheaper than GT-I9500 in the Motherland marketplace.
Also, is there anything that I need to check before purchasing? I can open the box, check what's on it, etc etc before buying it. Is there any fault I should check? Like S2 has few faulty models with bad chipset and you can check that easily before purchasing.
afaik the 9505 model has a Qualcomm 600 or 800, both in my opinion are better than Samsung's octa core. And besides only 4 cores are running at a time on the octa core.
It's more like two quad cores than eight concurrent cores. The one in the i9505 is faster.

2.there might be lags in overall animations but benchmark wise the octa core beats the quad core to the ground

I9500 is one of Samsung biggest failure, they rushed to launch it with their "octa" core, and they released an unfinished product with flaws.
I9505 it is faster after newer updates, and btw i9505 has OpenGL ES 3.0, i9500 doesn't.
So games will run smoother and with better graphics on Android 4.3+ on the i9505.

I lost my trust in Samsung Exynos processor due to the Mali issues in I9300 which make the development of I9300 way slower than the USA's S3. It took CM team so long to get a stable build out of it.
Anyway the good thing about the I9505 over the I9500 and for me even the Note 3 is having a Google Edition. At least porting new Android versions from I9505G to I9505 is easier and faster access to updates.
