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.
I just picked up a Pantech Burst and it is advertised as Dual-Core 1.2Ghz, but when I ran Qualcomm's Benchmarking utility (and Quadrant) - they all show 1.5ghz.
I called Pantech Support Line and they confirmed its a mistake!
Anyone else who has a Burst, download Vellamo, which is Qualcomm's Official Benchmarking Utility, to see the specs:
Cores: 2
CPU: 1.5ghz
According to Google it has a APQ8060 CPU. They may have had plans to underclock it originally, my Touchpad shipped with the same chip underclocked to 1.2ghz. But the processor itself is rated at 1.5ghz. Even on devices that ship with it set at 1.2ghz, its relatively safe to overclock it to 1.5ghz.
Hi, if you overclock Pantech Burst from 1.2Ghz to 1.5Ghz, did you notice any battery drain faster , and performance boost ?
Most everything is currently being discussed on another thread. atleast until we can get our own section on here

Hi,
I have a INEW V3 Plus Octa core and for some reason Antutu only gives it a rating of approx. 20,000
from what I have read the cpu is a 1.7ghz cpu , however in this phone it is ran at 1.4ghz
can anyone clarify this for me ?
and if it is the case is it possible to clock the phone to 1.7ghz ?
hoping someone can help
thanks
Stef
No you cannot clock the cpu higher. This cpu has similar name but not exact as the 1.7 model
Hello everyone,
I'm looking for information. I have the current use case:
My smartphone is a Sharp Aquos Zeta SH-03G with lollipop 5.0.2 (I didn't get a choice on the device I could get )
By digging a bit in the system I found out that this smartphone is configured somehow to not use the full CPU capacity. It justs use 5 cores out of 8 of the snapdragon 810 whatever the activity on the phone.
However all the core are seen as possible to use by the kernel with correct frequencies.
Only the core up to 1.5Ghz are use normally. for the core up to 2Ghz, only one is used and not at the top frequency (max 1.4Ghz)
Which make this phone to act as a 5 core up to 1.5Ghz. I'm just curious to understand where I should look like to see where that configuration is done.
Is it in the custom kernel source code? Is it some arguments given at boot time? Is it in some configuration file somewhere on one of the booting partition?
They release the source code of the kernel so I just give at least a quick check in the processor core frequency definition for a snapdragon 810 and it was looking like all is defined approprietly to use all of them. Also the system report that it really see 8 cores and that 8 cores may be use if needed...
Any help appreciated, thanks!
Hello Developers,
Greetings to everyone!
I am looking at the specifications of a device using the Qualcomm Snapdragon 400 processor which is advertised at 1.2 GHz speed. When I tried to boot up the device, the internal specifications only show 1.19 GHz. My thought is that the device was designed at a lower clock speed considering performance vs. device heat & battery life. Is this generally true? and is it advisable to design a device at full rating?
In a project/business scenario, how do we explain this discrepancy in lay man's term? (e.g. the business requirement is for a manufacturer to create a device performing at 1.2 GHz using Qualcomm Snapdragon 400 but the device is running at 1.19 Ghz only). What information can we request from the manufacturer to address the concern?
Thank you in advance!
