Haven't heard this one personally, however I should point out !Desk_Bogo is utterly useless as a benchmark, as it benchmarks literally doing nothing (hence the name). Dhrystone is only marginally more useful.

The frequently quoted 2668 MHz machine is most likely a Pentium 4. The Core i7 quoted for the RPCemu results will be vastly quicker clock-for-clock, therefore comparing performance across the different emulators based solely on clock speeds of these two very different machines is not very meaningful.
