Neoseeker has posted an analysis on Dual core
[...] n represents a processor with the highest clockspeed and each stepping is a 200 Mhz drop. A concrete example would be the FX-55 at 2.6 Ghz which would be n; n -1 would be a processor at 2.4 Ghz, n-2 would be 2.2 Ghz etc. Note that scaling back two steps is roughly a 40% reduction in power consumption. Because of the doubling of transistors however, heat output remains is actually a bit lower on the dual core 'n-2' processor whe compared to a top of the line single core processor with clockspeed n.Read more
