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.
Hello, Good Day.!!
Hey guys i am little bit confuse about my Xperia mini Hardware
According to GSM ARENA The phone has
Chipset Qualcomm QSD8255 Snapdragon
CPU 1 GHz Scorpion
GPU Adreno 205
What does the CHIPSET stands for i mean what is the work of chipset? is it a Mainboard??
Some people said the phone has Snapdragon processor but here it says Scorpion.Snapdragon is a processor or a chipset??
http://wiki.answers.com/Q/What_is_t...the_functioning_of_processor_chip_and_chipset
http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip)
Snapdragon is a chipset, Scorpion is a CPU. Every computer nowdays has both CPU and chipset, including smartphones. Also, in smaller/portable devices GPU can be embedded into chipset. IIRC Snapdragon is one chip that contains it all, CPU, GPU and Chipset.
Motherboard is a board that contain those chip(s)
The trends we are seeing in this part of the World (Asia) with the New Crop of "Value for Money" Smartphones is MediaTek Processors...
Be it Lenovo, Alcatel or all major vendors in Asia, China, Indonesia...they are starting to go with these Processors...
Having said that We see a lot of Bad Mouth about this brand of Proccy....so what the real deal?
All of us would agree when we are looking at a dual core smartphobe at under 200 $ prce bracket.....we cant expect a Snapdragon S3!
And looks like all new VFM Samrtphones from China OEM or other places who rebrand OEM are ending up being MediaTek!
Starting this thread to get some discussion going for more enlightenment....
Current MediaTek Proccys in Market :
- MT6575 : Single core Cortex-A9 solution with an unidentified 5-series PowerVR GPU
- MT6577 : Dual Core 1GHz Cortex™-A9 application processor from ARM, a PowerVR™ Series5 SGX GPU
MediaTek breaks into Top 5 in Smartphones Procy sales Worldwide!

bad mouth about mediatek, well i don't think so. mediatek processors should be at par with any other processors but the problem is afaik they dont release their kernel sources and they are still stuck with their sgx 531t gpu which is almost at par with our adreno 205 but not any better. however i might be wrong. i read about this a long time back and i dont remember the exact source.

They are on PowerVR GPU Now...on eh 1Ghz Single Core and 1 Ghz Dual Core chips
I'd suggest to move the whole discussion to "Android General". There you will certainly find more people to discuss your particular issues and do not spam this board. Thank you....even if I sound like forum police now :laugh:

I have some question on my mind before i buy new Android Smartphone !
please guide me about Processor
Like MTK / Cortex / Qualcomm / Scorpion / Snapdragon
may be its a brand but which one is better if they all is 1 GHz ?
or if they all Running on 1 GHz that means they all Dual Core or Single Core?
personally ask which one is better Processor ?
MTK6573 With PowerVR 531 GPU
or
Qualcomm Scorpian With Adreno 200 GPU
both are 1 GHz !
Dual core > single core

Both if both dualcore then which one is good? If both singlecore then which one is good?

Adreno 200 is a bit old for these days. All the processors have their pros and cons. It's up to you which one you buy. I prefer Qualcomm. But its not always the better choice
that means PowerVR SXG531 GPU is better then adreno 200 right ?
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!
