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!

sorry ,i have no idea
Anybody. Please help

Four, if you count the GPU, which is also a processor. There's no average speed: It is what they say it is. A system with processor, DSP, GPU and cellphone chipset. If you want to know the processor speed, look at that. If you want to know how capable the GPU is, look that up. The DSP and cellphone chipset and their speed is rarely of interest to consumers, that's why that information is rarely provided, but all smartphones have both (although they may sometimes on the same die as the CPU)...
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 guys
My phone is Huawei Ascend G525 which comes with Android 4.1.2 .
My question is that, what's the meaning of QUAD CORE 1.2 GHZ?
That's my phone's CPU specification and I'm doubtful about whether it has four core and each cores' frequency is 1.2GHZ or the sum of four cores' frequency is 1.2GHZ.
Secondly, how do you assess this phone's performance?(Regarding to its CPU)
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!
Could somebody please explain why the Snapdragon 821 @ 2.4 GHz has TWICE the single-core benchmark score compared to the MediaTek Helio P35 @ 2.3 GHz!?

I can confirm that Snapdragon 821 devices indeed perform way better when it comes to say, emulation, but the question is... WHY? (considering it's only 0.1 GHz ahead in terms of clock speed)
