I'm not a computer engineer so I don't know that much about CPUs. But what I understand is that Octa-core CPUs are technically Dual Quad Core. In the case of the Z5, when process demands lower performance, it only uses the 1.5 GHz Quad Core. When a process demands higher performance, it uses the 2 GHz Quad Core.
But what I noticed when I used SetCPU is that the Maximum CPU Speed of Z5C is just 1.5 GHz.
I would like to know how to set my phone to use the faster 2 GHz CPU.

It uses 2.0 GHz,
as long as the kernel supports it and the bigger cores are used, the smaller cores are limited to 1.5.
You're most likely using a CPU tweak tool that isn't big.LITTLE aware - so that isn't shown or not correctly
Cool Tool, SetCPU, and NoFrills CPU Control, all shows that the maximum limit of my CPU is 1.5 GHz, when it should be 2 GHz.
Could you please point me to an app which would show my actual CPU speed?

Try this one to detect speeds, you're not able to set anything with it but it should support BIG.little

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.
Hi all,
I have a problem with my 5770d tab.
The cpu only makes 1,2 ghz max. But it must have 1,5 ghz.
I had rooted it but any cpu app dos'nt work.
also it shows me the cpu is a arm v7 but it must be a cortex a8 i think.
can someone tell me what is wrong!?
Thx for your help and sry about my english.

Looking at the specs of the device it says up to 1.5 GHz max the manufacturer likely limited the max frequency to battery life and performance. To get the CPU frequency to 1.5 GHz and higher you would need a custom kernel that allows for the higher CPU clock speeds. Also the processor that is used is based on the cortex a9 architecture and uses the arm v7 instruction set (Hence where the arm v7 comes from). Let me know if you still have questions .

Hey, thank you very much! :good:
Then i know that everything is ok.
It´s too bad that there are no Custom Kernels and Roms up today.
Hope this will change in the future.

i´m not really shure but as far as i know the 2.1 revision of snapdragon 810 cpu should have a gpu clock speed of 630 MHz max., correct?
So, on my device the max gpu speed is 600 MHz. so i think the "old" 2.0 revision is buildt in or am i wrong?

Sony merged commit to enable 630MHz on Z5, but they didn't on Z3+/Z4 for now.
Maybe Sony will include it in future release.

I did not read the SoC's specs, but the clock limitations may differ depending on the manufacturer, not on the SoC.
Thinking of the overheating issues it's possible Sony reduced the GPU clock to reduce heat dissipation.

Yes.
Sony uses same S810 for Z3+/Z4 and Z5.
So I have the m4 aqua for quite some time, and I never actually read anything about it's SoC. Until just recently I came to see that Snapdragon 615 actually supports 1.7GHz frequency on the big cores. And I was about to ask if the cores are already clocked at 1.7GHz, and if not, can you even increase the frequency by any method (root required ofc)? I don't mind the heating if the raw performance can be improved, mostly asking for gaming purposes.

Idk but we have sources and good way to compile kernel with over clocking.. But i dont know, this is only my opinion

I think there's no difference. The best thing is the fact that CloudyRom is stock-based and Xcam is working. Xcam will not work with Marshmallow or Nougat. There is no driver.

How has your battery life been so far? I've read somewhere after some months it degrades, so on and so forth. Performance must be good though, no?

3 years old phone, it lasts a day with average usage.
When I set up maximum cpu frequency, I get better performance but lower battery life, still can be considered moderate.

I use these settings;
master core section
- cpu governor; alucard
- touch boost frequency - 1.95 ghz
- cpu touch boost interval - 350 ms
- affected cores on touch boost - 4 cores
- cpu governor sample rate - 10000 rate
- max cpu - 2.80 ghz, min cpu - 499 mhz
- max screen of cpu - 1.95 ghz, min screen of cpu - 499 mhz
cpu hotplug section
- hotplug driver; autosmp hotplug
- cpu hotplug sample rate - 10
- touch core boost - quad core
- touch boost duration - 1250 ms
- max cores online - quad core, min cores online - 2 cores
this can be considered as high performance profile, you can increase values but be careful of cpu temp. I use device for daily needs, I don't play games. It doesn't heat too much but battery drains a little bit faster.
Lineage 14.1, with the supplied kernel. Very stable, camera is so-so but otherwise the phone is a pleasure to use.
