I know N82 uses a TI OMAP 2420 as CPU and a TI OMAP DM290 GOLDENEYE for camera. Within OMAP 2420 there is an application core and a DSP, the first one is based on ARM11 and runs at about 330MHz, and the second one is ARM7 @ 206MHz. So for N82, no matter how heavy the task for the phone, the basic function like dialing won't be affect. But the OMAP 2420 doesn't support 5M Pixel camera, so NOKIA adds an OMAP DM290 which supports up to 7M Pixel's camera, realtime encoding up to VGA @ 30FPS, and multi format decoding. For this reason I think N82 will be strong not only in running applications but also in multimedia usage.
