can anyone confirm that cellphone CPUs runs like a ex, core 2 duo (speed step, etc) ???? i really doubt they use same function as a PC.
You're right - the great majority of cellphone CPU's don't come anywhere near PC/notebook performance.
It's only recently that higher powered CPU's like the Qualcomm Snapdragon became incorporated into mobiles such as Toshiba's TG01 :

SE,Nokia , HTC and other companies are seriously considering it for their next generation cellphones.
Some key features taken from the above site :
1GHz CPU
600MHz DSP
Support for Linux® and Windows Mobile®
WWAN, Wi-Fi and Bluetooth connectivity
Seventh-generation gpsOne® engine for Standalone-GPS and Assisted-GPS modes, as well as gpsOneXTRA™ Assistance
High definition video decode (720P)
3D graphics with up to 22M triangles/sec and 133M 3D pixels/sec
High resolution XGA display support
12-megapixel camera
Support for multiple video codecs
Audio codecs: (AAC+, eAAC+, AMR, FR, EFR, HR, WB-AMR, G.729a, G.711 , AAC stereo encode)
Support for Broadcast TV (MediaFLO™, DVB-H and ISDB-T)
Fully tested, highly-integrated solution including baseband, software, RF, PMIC, Bluetooth, Broadcast & Wi-Fi
you've been driven away in confusion with plank's post, we are talking about speedstep/cool and quiet(a feature that reduces clock frequency on processors while in idle to save power)-like feature on mobile CPUs and not on the comparability of their performance!
One more time: that JBenchmark test knows nothing about the CPU speed. It rather tells the story of software optimization. When it comes to C902 vs. C905 the right conclusion would be that the tested firmware on the C902 is better optimized than that of the tested C905. Which is no surprise since the C902 has been around longer.
