    Well, I think we were both right. :^) Mining ultimately comes down to the hash rate, or number of hashes per second, as you were saying. For example, this page compares Mhash/s, or millions of hashes per second, of various technologies:

    What I was saying is that the more raw CPU (and/or GPU) power (i.e., Gigahertz) you have at your disposal, the higher your hash rate will be, all other things being equal. However, specialized hardware (FPGA and ASIC) has been specifically designed to perform hashing, which makes them faster than a general CPU *for this specific task.*

    The following is not a real example, but the underlying idea is that you could have, say, a 2 GHz CPU versus a 1 GHz FPGA. Despite its lower clock rate, the FPGA could have a higher hashing rate because the CPU has to perform several instructions for every instruction the FPGA performs in hardware.

    Hope that helps.

    You were right Ken - It's Gigahertz that refers to computer mining power, not hash.

    Sounds like a fun meeting. One caveat: Remedy can get real busy on Sunday evenings so, while we should still congregate there, people might want to have nearby alternate locations in mind.
