1Ghz means 1Ghz... not 500-700Ghz. if the nexus s does have the orion dual core cpu running at 1Ghz, then it'll run at that speed. it will have two cores, both of which run at 1GHz. so what is the advantage of a dual core cpu if they're not going to up the processing speed? simple, look at your task manager. go into your apps, look at the apps you have running, or even the stuff running in the background or services. multi-core processors are designed to handle multiple tasks. they don't have a faster clock speed, they just handle multiple tasks. with the phones we have today, we are running just as many tasks on our phones than on a computer. since these phones are running so much, they have grown the need for multi-core processors. if it has a dual core 1GHz cpu, it will run at 1GHz. the only time you will notice the difference between that and the hummingbird 1GHz, is when running multiple tasks.. or gaming. the cpu isn't faster than the hummingbird, just much more efficient!
