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. >Indeed: that suspicion is supported by Chris Hall's benchmarks here >https://www.riscosopen.org/forum/forums/5/topics/466?page=8 >where VRPC on a 2668MHz PC gives only 175% compared to a bog-standard >S/ARM RPC, i.e. 1524MHz = 100%; the corresponding figure for RPCEmu >here is approx. 1000MHz = 100%. Obviously that assumes a similar >processor type in the 2668MHz machine, which may not be the case. 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.
