Higher cycles per second means it gets more done in a second. So holding everything else the same, higher cycles per second (usually called the CPU clock rate) means faster. A 2.0GHz Athlon XP is somewhat quicker than a 1.8GHz Athlon XP of the same kind. But you can't compare clock rates between different CPUs. My Pentium 4 at 3.2GHz would be much slower than an Athlon XP running at 3.2GHz if there was such a thing. You can only compare clock rates for a given kind of CPU. CPUs get different amounts of work done per clock so they're not directly comparable.1.8Ghz, i know it's cycles per second (now) but would that mean the higher the better?
