So there were rumors that we'd not get the Hummingbird CPU here in the U.S. with our "Galaxy S phones" and after running the app Quadrant Standard, I'm a little confused. Here's the results that confuse me and it could be a simple lack of my knowledge so if anyone has the answer then please feel free to clue me in without flaming.
Result browser:
Device: Samsung Galaxy S
Other names: I900
CPU Name: ARM Cortex A8 (Hummingbird)
Max freq: 1000MHz
Now for me; I have a Vibrant...
Device: SGH-T959
CPU Name: ARMv7 Processor rev 2 (v71)
Current freq: 400MHz
Max freq: 1000MHz
So does this mean we are NOT running the Hummingbird CPU or is the application wrong?

I believe that the arm v7 is a part of the cortex a8 family of processors, or vice versa.

Hmm, I wonder why the app differentiates the two CPU's like that. I'm not able to come up with much info from searching for that exact CPU name other than info on the Motorola Droid X. Go figure...
I ran the benchmark and I was interested.
I hit up ARM's website and the ARMv7 falls under the Cortex A8 platform.
Now is there a difference in CPU's between the I9000 and the Vibrant I honestly cannot say. Very Very interesting though.
I wonder if anyone with a captivate can tell us what there's says I am interested in this.
Do you guys think that Samsung could have cheapened out and gave us a crappier CPU?
EDIT: I did some digging and found out that Apples A4 processor which is pretty much a hummingbird is under the ARMv7 instruction set which is a Cortex A8 processor.
I was able to pull up the same info in regard to the iPhone 4. I found that quite interesting. However, I'm still curious about a Captivate's results. The GPU is exactly the same on the app's results but it's just the CPU thing that bugs me. Is it normal for the phone to be running at 400 MHz? I keep turning up with that same result.

The processor will throttle itself based on demand, so yes it is totally normal to see a number less than 1000MHz

My Vibrant shows Current frequency as 1000MHz.
Let's put it this way - T-Mobile and practically all marketing for the phones states it is in fact the 1ghz hummingbird CPU. If it isn't, then it is clearly false advertising.

So do we have any definitive answers on whether it's the same CPU that EU has? I've turned up with inconclusive results.

The Cortex A8 is from the ARMv7 family of processors.
Think of it like Intel i7 family of processors, and individual processors being i7 965 or i7 920 or i3, or i5 or i9, etc. or better yet like intel processors being x86, then with all the different things they add on like mmx and hyperthreading and the like being additional instruction sets. so over time x86 gets tweaked for better performance, and the other instruction sets allow for specific tasks to be run faster. hence the difference between the different arm families. that and price tag.
any mobile processor will also dynamically clock itself based on requirements at the time. I don't know the exact frequencies because I haven't cared enough to find out, but the processor downclocks itself to something like 250mhz with the screen turned off, then up to 400mhz ish with the screen on, and then up to 800-1000mhz when running any applications or games or what have you. It does this to save battery life and not run too ungodly hot.
Laptops do the exact same thing, and desktop computers as well if you enable those settings to save on power consumption.
also the cortex a8 is just the cpu itself as far as i'm aware, that does not include the dsp nor the gpu.
ALL SGS phones run the same exact processor, Samsung's custom Hummingbird processor, with the cpu being 45nm based on the Cortex a8 (ARMv7 series) with some customizations, along with the SGX 540, i don't know what their dsp is off the top of my head though.
This is interesting!
I have an incredible. I've noticed the exact same description for my processor using two different apps. If anyone has an answer I'd love to here it!

Snapdragon is also an ARM v7 CPU. basically ARM v7 is the CPU core, Snapdragon, OMAP, Hummingbird are all SoC(Systems on a Chip), where the CPU portion is ARM based.
As many of us know, our chipset is already on Turbo to 800mhz. The recommended is 600. Most of us are on the belief that it can still be overclocked... is it possible? Anyone familiar with hardware here?
(It may be a waste of time for developers include it and test a phone being over-overclocked... not to mention probable damage too.)

Ya its possible...1GHz is the max...and no developer right now its working on overclocking..and that 1 GHz will m make ur battery drain faster.....

No need to be so aggressive sir that would just sound trollish.
"simple search" arrives at a thread of your question about ace overclock, rumor of "1.3 Ghz" but can you include your source?
The chipset we're using, the Qualcomm MSM7227 chipset, is a 600mhz processor which samsung overclocked to 800.. If it's overclocked already at 800 I'm asking if it would be safe to do it further? Since some of us are under the impression that the processor is packaged for 800mhz as original.
it isn't overclocked, it's turbo boosted.
i know that these things are 2 different things.

Weird though it runs "turbo" most of the time in use..
Do you know the difference? Google brings no results.
Qualcomm msm7227 turbo
I actually met a person working in Qualcomm and i had asked him that if the processor on our ace is overclocked or not. He told no. It seems that qualcomm uses a better processor on the chipset whose regualr clock frequency is 800 MHz. I have used a ZTE blade and tried to overclock it and it hangs at 729 MHz and it has msm7227 chipset. Our ace naturally is at 800 MHz so thus AFAIK it can be overclocked

That is really helpful. X10 Mini Pro uses msm 7227 chipset too and the best people can push is 768 before it freezes... Okay I feel better now, this phone can get 1 Ghz in the future. Awaiting the maturing of the development of this phone!

Is there really no way to overclock our p500 to default 800mhz? i saw the samsung galaxy ace is running the same processor with us but the default cpu is 800mhz
Is there possible to overclock more to 800mhz for our p500?for me,748 stable for me,but when i change to 768,sometimes it will black screen and no responding n i got to take our my battery..
Sorry, physically it is NOT the same processor. I have explained it many times here. All those Intels/AMDs with exact same stepping sold at different freqs are also the "same" processor.

but i heard that for galaxy ace samsung has overclock itself to 800mhz?they say the original fre also 600mhz?
it has to do with the way the mass produce IC. They are not the same cpus. Google for terms, stepping and waffer to get the picture
This is just absolutely lost cause trying to explain this, apparently. If you assume that LG are complete morons who could sell their phone with 800MHz CPU but they decided that would be too cool, continue to do so. You own experience shows that the chip is NOT stable @800 MHz. Guess what, yeah it is not rated to run @ that frequency, that is why LG buys it cheaper and why it sells it clocked @600 MHz.
Bye.
[Discussion]
This thread is purely a discussion about our phone's processor ability to be overclocked.
Does anyone here have any idea how our beloved xperia mini/minipro/lww processor can be clock as high as 2GHz as opposed to its default clock speed(1GHz)? If you carefully goes beyond our phone subforums into the realms other phone you can see that much of the phone there can't be overclock as high as our phone can go. Eg; other phone with 1GHz processor can only be overclock to 1.3GHz.
Any ideas? Developers facts can be very helpful.

Well 1600 mhz is stable for me,I will try 2000 mhz as soon I install supported rom.About 1300 mhz max for some models looks stupid to me,I didnt read post that says that.

I've tried 2GHz on my phone, seems to be okay w/o any instability issue.
Fortunately our phone isn't maxed out at 1.3GHz, almost all kernel for our phone support up to 2GHz, what I meant is, phone like x10 seems to be maxed out at 1.3GHz. Just small increment from 1GHz to 1.3. While our phone can go all the way up from 1GHz to 2GHz doubling its default clock speed.
Sent from my Xperia Mini Pro using xda premium
i've only tried to run benchmarks on my phone up to 1.6GHz,
did not try higher speeds because i am worried about the CPU might break...
as per x kernel latest release, they have set the limit to just 1.8GHz.
seems that would be the safest our CPUs would reach but still its not same for all units.
i am not completely aware about the technical specifics of the CPU but it seems that it could have been made that way.
the only thing that would limit the CPU capabilities is the temperature and the battery capacity, since running an overclocked CPU on a 1200mAh battery is not that efficient.
You're not exactly correct OP.
My Active, with the OC Spartan kernel, goes up to 2Ghz on my device and its perfectly stable.
On my Desire Z however, stock Mhz is 800, and i have oc'd it to 1.9Ghz stable, thats over 140% (russian election pun not intended ) oc. It is one of the most highly overclockable devices yet.
So it's not only our devices that go to 100% of stock speeds. Ill remind you that companies, take some "malfuncioning" processor chips that might have a specific part of them not working, lower their speeds to make them stable chips, and then ship them out to manufacturing.
That is why some devices dont go over 1.9Ghz. Its just a matter of quality of the CPU. I know this because back in the days of the ATI9500, which was actually a ATI9700Pro, just underclocked because a pipeline was malfunctioning, so instead of throwing them away, they locked the pipeline and sold them as a lower budget Video Card. With some tools though you could unlock the pipeline and if you were lucky you could have an ATI9700Pro in the price of a ATI9500
I have one question while we are on this topic.
Our phones have MSM8225 chipset while the Arc S has MSM8255T (clocked at 1.4 GHz). I'm curious, is there any noticeable difference between these two chipsets? If there isn't why aren't our phones clocked at 1GHz?
The reason these go by 8255 and 8255T are stated in the post i made above. Same chips, different quality. It seems that not all 8255 can be stable up to 1.4-1.5Ghz, so they released a cheaper 8255 line that is clocked at 1Ghz.

You are completely right but I have to say that architecture has something to do as well on my old x10 mini arm6 I had a 600 MHz processor going at Max of 800 and something and now my lww arm7 can go as high as 2 ghz lol.

The maximum CPU clock frequency is placed by kernel developer, what he thinks is fine. It is not that phone's CPU can really put up with that high clock frequency.

Sure then the cpu had nothing to do when you clock a 600 mhz cpu to 845 mhz and it crashes?? come on that is a lame thing to say in this thread

What I ment, was that the actual maximal overclock frequency, where you can set it, is set by kernel developer.
You can set the CPU max frequency 1Ghz, 1.2Ghz, whatever. But the really maximum, which you can set, for example 2Ghz in Rage Kernel, 1.8Ghz in X Kernel, is set by kernel developer.
It is not tested that phone can put up with that high frequency. That is your own responsibility to try and risk.
Imagine cpus being made like cookies.Although you use the same ingredients not all cookies are baked the same, not matter how good your oven is.Cpus get out of the "oven" and tested for stability.The less stable are clocked lower, the more stable higher and that depends from the voltage they need to run and the maximum safe temperature that is allowed so the chip can last long time.So they say that chips which fall between A and B specifications (temp voltage etc...) are going to clocked to 1 GHz and those that range between C and D to 1.4 GHz.But those who are close to A are not the same as B, same with C and D.That's why some cpus clock better than others even though they're clocked at the same speed.At least that's how computer cpus were made if i recall correctly.
Its marketing trick.
Why should I buy WT19i when I can buy Arc S with higher clock rate.
Same processor because if processor is diffrent they would need to make new S1Boot,if in arc s is new bootloader patch wont work.

Hi all.
This is my first post here so forgive me if I've put it in the wrong forum.
I recently (6 days ago) bought a new phone, Ezio i95.
It looks like Samsung Galaxy S3/S4.
The specs are:
Quad core 1,8 GHz
2 GB RAM
Dual Sim
5" Super AMOLED screen (1920x1080), 440 ppi
But... In Antutu benchmark system info it correctly says that it is 1,8 GHz CPU (1741 MHz, to be precise). But, when I do the test, it sees only 1,2 GHz. When I try any app that does cpu scaling or any other cpu work, it also sees 1,2 GHz.
I searched for it on the net, but I didn't find anything conclusive. Actually, it seems that the CPU clock is really 1,2 GHz, but I don't know why and how do they sell it as 1,8. And how the hell Antutu sees it as 1,8?!?!?!
Here are screenshots:

And here is from mediatek wiki:
MT6589[a] Cortex A7 (ARMv7) 28 nm 1.2*GHz quad-core PowerVR SGX544 @ 286*MHz
Any Ideas?!
Thanks in advance.
System won't let me to post a link, because I'm new, so I tried this workaround. Hope you don't mind. I've put two spaces.

I am not familiar with the device or the ROM you are using (stock?). But if you install cpuspy it will tell you all the freqs that are allowed and how much time your cpu spends at each freq. My guess is that the freq table goes up to 1.8GHz but that somewhere the maxfreq is set to 1.2 GHz. You might be able to up the maxfreq using an app like setcpu. The cpu you have is rated to 1.2 GHz so any overclocking you do comes with the risk that you will damage your phone. Basically if the cpu is getting hot....better back off the overclocking.

Every app I tried, including SetCPU and CpuSpy, shows 1,2 GHz as max frequency. As you can see on screenshots, Antutu benchmark shows in system info 1,8 GHz (1741 MHz actually), but in test it uses 1,2 GHz. TBH, the only place I saw 1,8 GHz was in Antutu, not anywhere else.
I contacted the seller, and he is trying to convince me that the phone has CPU Booster and that frequency is really 1,8 GHz. I now sent him screenshots in order to convince him that he is wrong...
I researched that cpu, mt5689 and its max freq is 1,2. mt5689T is 1,5 GHz, but this one is without T.
Kernel version is 3.4.5, from 19th June this year
Baseband version: MOLY.WR8.W1248.MD.WG.MP.V6.P4, 2013/05/04
Android version is 4.2.3

If that anything means to you...
I am not trying to overclock my phone, I just want to be able to use what I've payed for. I could have bought 1,2 GHz, but I payed for this one and I want to use it, that's the poing...
Unfortunately, only after I bought it, I found all this. I didn't inform myself enough, before purchasing...
Thanks anyway
The seller is still trying to convince me that the max cpu freq is 1,8 GHz, with cpu booster, but I still cannot see or use it in any app, except that Antutu benchmark sees the 1,8 GHz as max, but still uses 1,2 GHz.
Chipset and cpu is rated to 1,2 GHz, as I saw on mt6589 reviews, so I think that I am fooled...
Good morning, my name is Jorge Martinez, I am another ezio buyer i95, I arrived with several flaws, the most serious the gps it is impossible to make it work, even after following many online tutorials.
The on / off button sometimes gets caught and resets.
The headphone connection is not good and sounds bad.
Reviewed this to the salesman told me they would give me support, etc, etc, told me I was going to wait to send another new model, gave me all kinds of options, but ultimately it only to gain time.
Once you pass the time of the vote, and has forgotten all its commitments and ripped me off.
I recommend everyone to not deal with the seller, who has only good words but deceives.
I hope my mistake serve for one to be saved from falling into this trap, but also effectively tells you it's quad core 1.8, it's actually 1.2.
Greetings all, I hope this information will be useful.

ezio 95
hi,
I have read that some of the specs get rewritten within the operating system to fool antutu.
However I am also after a copy of the stock rom. I have a enzio s89 that I have bricked before I made a rom copy. This ezio i95 uses the same processor and is about the same size Maybe it will work in mine.
Are you able to download MTK droid tools and make a copy of your stock rom please. That is always worth doing in any case.
