The remainder of Nokia N97's technical details have been posted on the Nokia dev forum. Apparently the N97 will be powered by a single-core ARM 11 clocked at 434MHz which is just 65 Mhz than the 5800's. It is zippier but when compare it to the Samsung i810 which runs a higher-performance 600MHz ARM Cortex-A8, it is nowhere close to fast. Lastly the specs sheet reveals that the N97 can be charged via Micro-USB something which the 5800 cant.
