I assume your adding your core speeds together in making this magic 16Ghz chip, If the electricity is free? as much as you want. If not, don't bother. The whole idea of CPU mining is flawed esp. for all these scrypt clone coins that use it as some kind of badge even tho GPU miners are already out there and make CPU mining them irrelevant. The only coin of not recently that had any leeway into CPU only mining is YAC, but now that the N-factor there has risen the hash rates have dropped considerably.
You forgot to mention, that difficulty at YAC keeps adjusting quickly, so the avarage earning doesn't change too much. There maybe are some individuals that are mining YAC with their GPUs (instead of mining some more valuable coin), but these will stop latest in August when N is high enough to make GPU mining worthless. So with your 16Ghz CPU power you will mine maybe 10YAC per day in a pool which is about 10-12 USD a month at the current bter price.
