I know this device has a 1ghz Snapdragon in it.
But ... what I want to know is if it is underclocked like my G1 is?
no, it has profiles (similar to speedstep in intel CPUs) that automatically lowers the frequency to ~600mhz if the CPU is idle. Under load the CPU will go up to a max of 998mhz. This is according to the SetCPU app.
no wonder i see the cpu is 662 Mhz
but why the total physical memory is showed as 228?
where do you see that?
I think the 288MB you see is the total user usable memory. the rest of your 512 is used up by the system, radio and such.
download an application called "quick system", it will show the information
wow! you drop from 512MB total RAM to 288MB usable RAM?!?! that's worst than the G1's 198 to 97.
I'll tell you what, either way, it's fast as hell.
The device scales itself from 245-998MHz. BogoMIPS as indicated in /proc/cpuinfo is not accurate clock-for-clock for CPU speed on the Snapdragon.

All tools i used to identify pocessor speed says that on my Loe CPU clocked at 512 MHz.
Is there any proof of 1GHz ?
Most such tools need to specifically support a CPU to give you a reading. Its probable that none of them support snapdragon. It could also be giving you a reading based on power saving throttling.

is it necessary to check and confirm it?? An experienced user will feel the difference right away! HD2 is so speedy and instant, it tells everything!
I need to know that as well
go to qualcoom site, for this what is there our snapdragon is have the same number identity or else like this from htc hd
sory for my english
So I was wondering if there is any hack that would add more ram to the GPU, comparing to RAM hack that takes GPU RAM and gives it to Phones RAM, Could it be done vice-versa, so take ram from Phone RAM and giving it to GPU, could it be done? and would it increase GPU processing power?
i too was wondering this too because im a heavy gamer
I'm just assuming but, the RAM pool is all the same RAM chips. It's just being managed and distributed between the GPU and CPU by software.
But I'm not sure.

Same here, but again im not sure
http://en.wikipedia.org/wiki/Tegra#Tegra_3
Wasjust reading this and it says the CPU goes to 1.3Ghz in single core mode. does that mean 4 cores run at 1.2 then it shuts 3 down and bumps one of them to 1.3 if it needs it?
also anyone now the memery the gfx uses
4 cores @ 1.2Ghz = 4.8 G-ops/sec
1 core @ 1.3Ghz = 1.3 G-ops/sec.
So, the answer to your question is yes and no. Under an idle condition (not sleep) where there is little processor load or runnable threads, there will be only one CPU running @ 1.3 Ghz Fmax. (It can of course be running at a slower speed than this based on what the rate governor has decided) If the demand changes so that one or more additional cores need to be brought on line, the Fmax is constrained to 1.2 Ghz, and those additional cores are brought on line as needed. It may or may not have actually been clocking at 1.3 Ghz when this happens, but probably it will be.
This answer applies to the STOCK kernels. All of this behavior is under control of the kernel, and some of the dev kernels alter this code with different behaviors.
cheers.
Niice info man. thanks very much. any idea on how much RAM the gfx uses?

No clue. Don't even know if the GPU has some private SRAM on the SoC. Consult the Tegra 3 TRM for that. But, a single-layer 24-bit framebuffer @ 1280x800 needs 3MB for a single layer. Add in z-buffering and whatever else the openGL ES (1.0 & 2.0) libraries do with offscreen/onscreen primitive storage in userland memory space and I suppose it can be much much higher than that.
Somehow I sense you are asking about kernel-reserved memory; I don't know if the kernel reserves some minimum amount of general-purpose RAM (e.g. for the framebuffer) or not. Sorry. (Use the force, read the source!)

No im thinking more a portion of the 1gb system RAM was given to the gfx to play with. so our system RAM is only say 768mb
I want to raise question is it possible to overclock the CPU, or GPU or memory speed. We all know that ze550kl / z00l performance with msm8916. Is almost in the limit to run apps and games, wanted to know if possible or not, and if there is any development has this respect. I like the device and it is great but it is clear that it is getting weak in the matter of hardware, if someone can work in this respect to give a breath / power to our device

i don't think so , if its possible to overclock the processor to its frequency,
you can costumize it too max frequency of it or to lower , as u need
But if is then i would love like to know too
I am already extracting the maximum, from him that I can of him, already put using ex kernel, with governor ordenad, frequency of 200mhz @ 12000mhz, and simple GPU ordered frequency of 200mhz to 400mhz, active zram of 512mb, and entropy of 128/256, then Of course, here with standard frequency of the paddle extracting nothing more than that, the problem and that we have a large bottleneck in memory lpddr3 of 533mhz, that opera and 32bit, there is a single channel giving bandwidth of 4.2gb / s that It has to be split between CPU and GPU. What is clearly one of the pro soc power limiter, I do not know much about the arm architecture, but I can not do over clock in lpddr3 memory, since I did not see any software or tutoring Citing this. Although this would be a solution, if you do over clock in the CPU or ns GPU will force the clock controller up what will increase the memory performance consequently, something else, not good will lock the clock at maximum in 1200mhz and GPU at 400mhz, as there will be a large power consumption and the performance will be limited by the cords of the tempering control and the low frequency of the RAM, # excuse me to have been so far more enthusiastic about hardware,
even with my old htc explorer i could increase cpu clocsk from 600mhz to 900mhz why we cant do it on zenfone 2 just we need good developer and kernel
it's up to the hardware
If you look at the specs from qualcom it has a max speed and not every device is possible to reach the max, but if you have the proper kernel you can reach that speed and "overclock"
ok so as we know the xt has a Qualcomm snapdragon 616 cpu, the GPU frequency is 550mhz as max but everytime i see the stats it stays locked at 400mhz no matter what you task you do. Is there a way to override the frequency lock and make it reach 550mhz?? i think that would make the phone feel smoother and handle intensive tasks even better. Hope i get an answer soon.
