Aparently the CPU may only be clocked to 800Mhz........
If you got this from the Au website, Whirlpool, than I think they are talking about the iPhone 4, not the Galaxy S
well it's from the galaxy s thread and one of the guy who's doing the testing and stuff for samsung says this......definitely not iphone.
Guess just wait and see when it's released I suppose
huh? wat are you guys talking about? its 1ghz cpu
forums.whirlpool.net.au/forum-replies.cfm?t=1409745&p=58#r1152 is the link to the post where the user suggests it is 800mhz underclocked.
Yh, sorry, was reading a thread where they were talking about the iPhone being underclocked, just reading more, it seems it may be the case.
Will mean battery last longer, not such a bad thing, as long as it doesn't effect any of the performance of the phone
If they say 1Ghz then it is 1Ghz or else they're going to have a lawsuit on their hands. Nothing in between(except of course scaling).
I have the galaxy s and im pretty sure its 1ghz.. at least system panel tells me its 1ghz but singapore set are all 16gb model.
information from system panel:
ARMv7 Processor rev 2 (v7I)
bogomips 797.90 (may vary)
min clock 100mhz
max clock 1000mhz
on Nexus one using pershoot kernel but cpuset at 245mhz - 998mhz, it shows:
ARMv7 processor rev 2 (v7I)
bogomips 662.40 (may vary)
min clock 245 mhz
max clock 998mhz
so maybe the 8gb are down clocked?
Doubt the 8Gb version would be clocked lower. Thanks for posting your findings!
It's just the power of forums and the internet, allowing mis-information to spread at the speed of light
lol yep, looks like he was confused at the sliding clock speed....
when i ran quandrant standard it read armv7 processor rev 2 , max 1000 min 100
set frequency 800
is that normal

It's 1 GHz, I checked the clock frequency with a monitoring application and it's dynamic but when required it clocks up to 1 GHz.

Wait, what?
The iPhone 4 may be clocked at 800mhz?
Can someone give source on this?

I don't have a link to that claim, but I think it was Gizmodo in their testing of the iPhone 4 and iPad noted the iPad did feel faster and the web browser rendered pages faster, despite both using the A4 processor. They hypothesised that it is the same architecture CPU in both, but different clock speeds.
After all, to get 10 hours out of the iPad the teardowns and x-ray scans show about 80% of the volume inside is all battery. If the iPhone 4 and iPad had the same processor, you'd think the iPhone's battery would be pretty bad considering the far smaller volume (although smaller screen not sucking as much power).
Wouldn't be surprising. After all, the Motorola Milestone / Droid has a mild underclock, as does the Acer Liquid to preserve battery life.
Probably cheaper for Apple to only have to manufacture 1 chip (the A4), but clock at different speeds appropriate to each device's battery life.
Apple doesn't focus as much on specs though, more that the user interface feels fast and smooth. If it achieves that purpose no need to worry about numbers, whereas since we have so much choice of handsets on Android specs do make a difference for us to know depending on our needs (eg: price vs performance vs battery).
My Samsung Galaxy S is running at 800mhz it sucks... i flashed it last night with the final build of 2.2 I9000XXjP6 for the Galaxy does anybody no how i can overclock it to 1ghz thanks People
The Galaxy S has a 1 GHz CPU. However, the clock speed is lowered while not needed to save battery life, just like on any modern PC. By default it is using the conservative governor.
The iPhone4 never was supposed to get a 1 GHz CPU. Apple never disclosed the number. But those who made benchmarks estimated the clock speed at about 800 MHz since is is about 20% slower than the iPad.
There is a Galaxy Lite version in some other countries that only maxes out at 800 Mhz
i think the guy reviewing the phone got it mixed up with that

He might have got mixed up, but the final 2.2 build for the Samsung Galaxy S is maxed out at 800 MHz for some stupid reason…. I’m going to flash it tonight again with a earlier build of 2.2 as I did some bench test and its only scoring a measly 900 points with the latest firmware installed.. Were as before it was scoring well over 2k…
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.

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.

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

Im an Electronic Engineer so forgive my not understanding peoples confusion with the ghz thing but ...
Frequency is a rate, its speed, this is not a volume or value, were aren't saying they have 2MB of memory, is it 2 each or 1, 1.
Time runs at 1hz for me, as it does for everyone else in the world, do we share the 1hz or is it equal?
The hardware design determines the clock frequency of a cpu core, it doesn't, matter if you have a single for 1ghz, 2 core 1ghz or 20480 core 1ghz,
As long as those cores are they same, they run on the same clock.
To ask if they share the clock time would be like saying I have a guy that can do 2 sums every time the sun rises, now I have 2 guys that can do two sums every time the sun rises, do they do ne each? No, sun rises once a day and each of them does two sums, so you get twice as much work out of them in the same amount of time.
That might raise the question, well, while dont we just have 50 cores?
Well, its expensive to manufacture, its subject to low yield, it expensive and power consuming, also software has to be written to take advantage of all the cores (if you don't have enough sums to give your two guys, they can't give you results, right?)
Anyway, point is, the frequency is a rate, and don't for a moment assume that higher frequency automatically means more powerful processing. (Its true to an extent, but only within the same architecture.)
Macbots drool as I XOOM through the Galaxy to my hearts Desire.
good analogy, I use the car & highway one... 2 cars 1 lane for single core or 2 lanes and 1 car on each lane for dual core..

Lol, there is no _total_!
1GHz is the frequency that the CPU core clock runs at, they all run the same, on the same clock, 1 core, 2 cores, ten cores.
You need to understand this concept that "total" doesn't apply here.
This is not "1GHz per core", the core clock frequency is 1GHz, and there are two cores, they BOTH run at 1GHz.
This is the first dual core I've had, and I don't know much about the technology.
What's the difference between a dual core cpu running @ 1GHz and a single core running @ 2 GHz?

2 cores both running at 1ghz still equals 1ghz...1 core running at 2ghz equals 2ghz.
Lets try this:
If two cars are both going down the road at 60mph, how long does it take them to go 60 miles? Even though there is 2 of them, both running the same speed, it still takes 1 hour. Hope this helps you understand.
Am I right in believing that with two 1ghz cores, there would be no benefit in speed unless the app or OS were specifically designed to utilize both cores? My understanding was that if you had two 1ghz cores, and the app was programmed to utilize both cores, each core would handle it's own load. Is this wrong?
Does two 1ghz cores truly equal 2x the speed if the app is programmed to use both?

No, it depends on the application's workload more rather than the programming. If the application can split its workload into parts that can be done in parallel, you get a speed increase. However, if the application relies completely on having to have one part that cannot be broken up into parallel-running parts, then you will get absolutely no benefit from a multiple-core processor.
Mostly, dual-core processors are about *efficiency* rather than *speed*. Here's a good analogy. It's about being able to walk and chew gum at the same time, rather than having to walk a bit, stop, chew gum for a bit, stop, walk a bit more, stop, etc.

Hi there!
I am in the hunt for a 7"-8" Android 4/4.1 tablet. Currently my choices are the new Acer Iconia A110 (because of a microSD card slot), the Motorola Xoom 2 Media Edition (because of the bigger screen, excellent build and virtual surround sound), the Samsung Galaxy Tab 7.7 (again with a slightly bigger screen, a microSD card slot and an excellent AMOLED screen) and the top dog Google Nexus 7. But i am more interested with the Nexus 7 in terms of "Is it worth the investment" even on a small screen?. I will be using the thing mainly for checking email/news/weather, the usual Youtube, WIkipedia, Twitter, watching movies and also gaming. So, i'd like to ask:
1, Is the actual GPU dual or single channel? And what's the frequency? Does it matter?
2. Is the 1.3Ghz the base CPU speed? Or is it underclocked like what Apple is doing with its tabs?
3. Aside from connecting a mice or keyboard what other stuff can the Bluetooth 3.0 standard do?
4. Is it capable of wireless file transfer to & from a Macbook?
5. I'm aware that it doesn't have Flash but can i still install them via the Google Play?
6. Are they stereo speakers? Capable of surround sound? (some sound issues in some models i heard)
Please advice. Thanks.

Would you trust Acer when it comes to build quality of its tablets compared to say samsung or Motorola?
1. Not sure(I think I heard about it being overclocked somewhere)
2. Default is 1.2ghz, can be overclocked up to 1.5ghz.
3. For example: File transfer. If you root you can also use it as a PlayStation controller with BluePutDroid.
4. There are a number of ways to do this, I would recommend AirDroid.
5. To get flash(no root required):
A. Go to settings->security and enable unknown sources.
B. Download and install the flash apk on your device from here: http://forum.xda-developers.com/showthread.php?t=1763805
C. Get a browser that supports flash like boat browser(from play store).
6. Stereo, probably not surround sound.

I believe the nexus 7 has dual channel WiFi, using speed test app the speed reaches or goes above my maximum speed from the other end of the house.

There is no such thing as a single or dual channel GPU. Channels refers to the RAM. It is a 12 core GPU.
1.3ghz is the maximum clock speed of the specific CPU used, the T30L. It is not underclocked.
this is the truth after reading some ****.no single or dual gpu.12 core has.channel intended only for the ram.this is the minor tegra3 out there,less freq. clock but high clocked ram and not the same as t30 packed.begginnning with the fact the clock cpu freq. is overcloccable without problems,the ram packed on n7 is IMHO better than ad example tf201 or htconex one's
Are you guys certain there is no such thing as single or dual channel CPU?
And If the GPU clocked speed is 1.3Ghz would it mean that there is 1.3Ghz on each of the 12 cores?

no you are wrong man.the CPU(4cores) is clocked at 1.3 ghz (4 cores running) and 1.5 (or 1.4 i don't remeber)in single mode (1 core running)
the GPU (12cores)is clocked at 416 mhz by default
apart them,if you flash a custom kernel,this Soc can reach (depending on tab,they aren't exactly the same chips)1.8\2.0 ghz for the CPU,and 484\520\600\650\700\750 with the GPU (here depending on tab as well)
I see. So, it is fast?
As a side question would it be practical to buy a new or latest tablet like the Nexus 7 than an older (and equally good in its own) say Galaxy Tab 7.7 or the Xoom 2 Media Edition? What i'm trying to ask here is the "problem" of compatibility with apps and games if a tab has an older GPU in them.
Would that be an issue or not?
yes,sure it's fast!a little bit faster than others with same chip.i do you an example regards the last question.
there are peoples with old gpus,that continue playing hd games with these old gpu without problems (not all games working,but many of them!).an example is the galaxy nexus that i own,it 's packed with a good cpu and a old gpu,that we found also on galaxy s,nexus s ecc,but honestly i never found a game that doesn't work for the odl gpu.i have also tegra2 devices,no prob with games,surely a tegra3 is more powerfull and you can play games with full effect enabled without problems.all apps works,not depending to gpu,but only the version of OS at least.
The Tegra 3 SoC only has a single channel memory. Specs are 1GB RAM of DDR3L -1333 MHz (Low Voltage) giving a total memory bandwidth of 5.3 GB/s, is this super fast, no, but it is more than than sufficient for the Nexus 7 display resolution.
To the OP, don't get stressed about specs, especially if you're 100% sure what they actually mean. The important part is user experience of the Nexus 7, due in part to Android Jelly Bean, it is smooth and enjoyable, it can play all the latest games well, I also run Playstation & N64 emulators on it without issue.
Finally, The Nexus 7 is fully unlockable, so it has great developer support on XDA and other forums, which is 50% of the device's appeal in my eyes. If you can wait a few weeks, the rumour is a 32 GB model will replace the current 16 GB version.
If you can manage to find a Nexus 7 used on Craigs or Ebay, I would do it. I got my perfect condition barely used 16gb for $160 from a buyer's remorse user on Craigslist. For this price I find the tablet to be very good. I would have a harder time paying the $250 plus tax in store for the same unit. Not that it's not worth the $250 but already owning a Galaxy S3 phone, it's too much of the same at the end of the day, much like I experienced when I had a iPhone and iPad together.
The Nexus7 for me is a great grab and go device for quick browsing, game playing, weather checking, etc.
If you've got to have the latest and fastest specs, the Tegra3 is getting dated already and you'd want to find something with a Qualcomm S4 chip (even this isn't really faster than Tegra3). Supposedly the OMAP 4470 in the bigger Fire HD and the Nook HD+ might be a little faster for more money.
i doubt 4470 it's faster than tegra3 (all 3 variant)..it's basically a 4460 with a bit more clock freq.,same 45nm tecnology and with a faster gpu (with dedicated 2d hw chipset).they claim it's up to 2 times more faster than sgx540.if it's true,i think that tegra3 is better (not for the quad).Anyway i have to agree with all the things sad in previous posts.OP don't care about spec,a nexus device is fast for many others things that i don't write,already sad,and also if tegra3 it's becoming an "old" chipset compared to new out this days,it performs very well with an optimized OS.wait for the 32gb version and never ever think only about cpu\gpu specs :good:

A full fat OMAP 4470 is faster than the Tegra 3. I read a review of the Archos 101 XS which runs an OMAP 4470 @ 1.5 GHz (GPU 384 MHz)
In the ultra demanding GL Benchmark 2.5 - Egypt HD (Offscreen 1080p)
Nexus 7 = 8.9 FPS
Archos = 11 FPS
Transformer Infinity = 11 FPS
There is scope for the 4470 to run at 1.8 GHz, but that is probably only for larger devices like Windows RT tablet, Amazon apparently have clocked it at 1.5 GHz. Overall in a tough benchmark the N7 is slower, however the Transformer Infinity is the same speed, which is basically as fast as an easily overclocked Nexus. As the OMAP is a dual-core, in theory a game developed specially for our Nexus (Tegra Zone?) could be faster or more feature packed in terms of physics etc, if it use all 4 cores.

months ago the 4470 was supposed to run at 1.7 ghz.i remember when i bought the gnex in november 2011 that 4430 is at 1.2\4460 at 1.5\4470 at 1.7.theese number was in the official omap site and guide line referments.only after being out the fact of the 4460 bug (major part of them,wasn't capable of 1.5 ghz,and this Soc it isn't a downclocked one,from 1.5 to 1.2 by google.it's a 1.2 cpu.)they change also in the site some numbers.now the 4460 is at 1.2 and the 4470 there's write 1.3+,in this case of the archos 1.5.what a strange thing from omap!i saw same anandtech reviwe like you sad times ago,but honestly i think that in the total of bench that regularly they do,there are some in favor of 4470,and some in favor of tegra3,at least depending also if referred to cpu or gpu.with 4460 they did a good job,i really like it,but after have a look at 4460\70 documentation,seems that in term of cpu,there aren't so much differences.if i clock my 4460 at 1.5\16,do a bench and compare with a same bench do with a 4470,i think that the most differences are gpu related..and when i compare my bench with n7 and gnex,in term of cpu and both ultra-tweaked i see a big gap in scores...it's for that i continue to think in the total user exp and bench scores as well tegra3 remain more powerfull.but certainly the differences aren't visible by end user..but with bench at least and in th end what really count it's how's the user experience,not bench

An area the 4470 does hold a significant advantage over Tegra 3 is memory bandwidth, as it utilises dual-channel memory, hopefully Tegra 4 will sort out that deficiency. Ultimately the OMAP's GPU is not powerful enough to be bandwidth limited anyway, overall I like the Tegra 3 from a UX perspective, looking forward to a Tegra 4 in the next Nexus 7 v2:good:
Using a nexus 7 now. Very happy with the money I paid for it. In terms of spec? This beast will last you for awhile. Even if they are pushing specs already to the next level, it'll be a long time until a quad core 1 gb ram machine will be considered slow.
Simply put, at this price and quality, anyone can buy it and everyone should.

The 32 gig will be replacing the 8 gig model. Two versions will be available by Christmas: a 16 gig model and a 32 gig model. The 16 will be priced at (or below) $200.00. The 32 will be at (or below) $250.00.

You have a link confirming that, or is that inside knowledge
It's the logic step for Google. The 32 gig is already being sold and nobody really wants the 8 gig model. To compete with the "other" tablets and to make up for the lack of an SD card slot, it only makes sense.
IOW.....my speculation from 40 years of computer use....starting with the Heathkit H8.

Newbie here and first post.....
When I purchased my note it was touted as having a quad core 2.3 GHz processor. When running AnTuTu the max CPU speed seems to be limited at 1.49. Is there something that I am missing?
Any guidance is appreciated!

Should be in QA but turn power saving off.
