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.

Are you sure?? I have read everywhere it is 500mhz!! Othwise why do manufactureas say it is a 1.2ghz dualcore phone?! Why dont they say it is a 2.4ghz phone? I think you may be wrong

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.

thanks, but why does it say for ecample that the htc sensation runs at 1.2 ghz? If they want to be more impressive, why dont they just say its running at 2.4 ghz?
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.
Regards.
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

Because they would be lying. If I have two towers each being 50m tall I can't advertise that I'm selling a 100m tower because I'm not.

i see you logic now
but you could say in total you have 100m tower? so could you say i have a 2.4 ghz clocked phone?
pk i saw there is a new kernal to over clock the iconia running 3.1 up to 1.6ghz.
ok now for the total noob question since this is a dual core tegra do both cores over clock? i guess what i am wondering is all the specs say dual core running at 1.0 ghz stock so is that 1.0 ghz per core or combined? and if you over clock is it both cores or combined that over clock?
side note love that this is first tab with ddr3 lol take that xoom now if they just would have put the ips screen in it and 16 mil colors instead of 256k this would be the tab to beat hands down.
Is 1GHz per core; overclocking will increase the maximum speed of both cores. Note however, as with virtually every modern processsor, the Tegra2 throtles perfomance based on current activity to increase battery life
Thanks
I figured that was a silly question, thank you for answering. Its been 110 degrees here and I work outside, I think I baked my brain because as of late simple things really confuss me. LOL thanks again.
While reading anandtech's review for nexus 7, It says "The only difference is that CPU clocks are 1.15 GHz for all four cores at 100%, or 1.3 GHz on a single core." Does this mean if I underclock my nexus 7 to 1.2ghz I'll be able to use all cores? Thanks in advance!
What the review is stating is that with standard rom and kernel from google its settings mean that it can only work at 1.15ghz on all four cores at once, with other kernels you can overclock this to be more at once or less depends what kernel you choose. Tbh mostly you wont notice a difference unless benchmarking but what use is a benchmark Id say you should judge a device by using it not by what a test tells you
Anyone knows why all apps i downloaded (cpu-z, monitor cpu, setcpu) only show max mhz at 1300?
i have a sm-g900h with arm15 cortex r2p3 , i understand that is an octa core with 4 cores at 2.1 ghz and 4 at 1.5
It is a phone problem or all these app don´t support the system?

It's likely most app do no "fully" support this new octa-core. I would suspect they only show the little CPU 4 cores @ 1.5GHz, however seeing 1.3GHz as the max is weird. In S4 octa-core, the max frequencies was used by both CPUs and frequencies below 600Mhz where meant to be used by little core (600Mhz being 1.2GHz on the little CPU, 700Mhz being exactly that on the big CPU), so there might be some similar tricks on the new S5. This would mean the kernel would only show 4 cores at any point in time.
Have you tried Android Tuner, it can adapt to any number of cores automatically (a little down arrow allows to switch to multi-core control) ? If you try it, can you post a screenshot here? I intend to buy the Galaxy S5 with 8 cores for testing purposes, so I'd be interested by first-hand screenshots, if any. You can check and post screenshots of the main CPU tab and also the Times tab which will show available cores timings for each frequencies.
Hi all,
The Snapdragon 625 is one of the best mid range processors. It is powerful and very power efficient. I can get at least 5 hours of sot. In cpu z only all 8 cores can be used at the same time and they all have the same frequency (generally 652, 2016 or 1401 MHz). Does anyone know the clock speed of the two quad cores that make the Snapdragon 625

The Snapdragon 625 is not a littleBIG architecture processor, all cores are the same, it is a true 8 core processor, not 2 quad core processors.
Ok thanks! So can each core can't go at their own frequency and all 8 cores must work at the same time.

No, hey can throttle independent of each other, my guess is the default governor of the kernel does it that way because there is no real power savings.
True. I have a feeling that if the kernel allowed each core to run when it was needed and stopped when it isn't it would have been more power efficient.

Maybe... But the SD625 is pretty efficient as it is, plus there is a lot of issues with programs that report core usage on Nougat, it might actually be doing that but reporting incorrectly.
True. I tried 3 apps similar to cpu z and I got the same 3 frequencies and all the cores were being used. Do you think the Oreo update might fix that issue.

No idea... My guess is no, most of this is due to changes in Android permissions, but honestly it works, it's quick and lag-free and great on battery, so I don't care about the details.
