Ok guys, I am pretty sure the OC Kernels
do not overclock the CPU. Either this, or the power management / frequency management gets messed up and the CPU ends up not running at higher speed all the times.
I tested stock and with 1200MHz Kernel.
I did not root the phone, I just flashed the OC ROM, so if that is needed in order for the frequency to be applied please let me know (however, the software does see the CPU at 1200MHz).
For testing, I used a bunch of apps (some of them are 3D, I know, but I wanted to see if CPU OC has impact over 3D performance, just like with 3DMark on PC's, for instance).
Besides the synthetic benchmarks, I also used two real life applications to make sure if the real life performance is changed or not.
With Batch Image Resizer I resized 72 JPG pictures (84 MB total size) to 50%, and I also rotated them 90 degrees clockwise. This resulted in 72 files with a size reduced to 15MB. The operation took 57 seconds with the OC kernel and 52 seconds with the stock Kernel...
With Video Converter Android I converted a 3GP movie I shot with the camera (75.6 MB) to MP4, with default settings, resulting in a 28 MB file. The operation took roughly the same time to complete with both kernels (186 seconds).
That being said, it is pretty abnormal for a 50% frequency increase to have little or no impact for performance, so most likely the OC kernels do not affect the real operating speed of the CPU.
However, I would very much like to see how this baby runs at 1200MHz, so if I can be of any assistance for testing kernels and stuff, please let me know.
