Clockspeed bears any useful relation when comparing different microarchitectures. Here's an extreme example from the MIPS history:
o R4400 250MHz ~ 130 SpecInt92, ~ 138 SpecFP92
o R8000 75MHz ~ 135 SpecInt92, ~ 320 SpecFP92.
An R10000 delivers about twice the performance per MHz than a Sibyte SB1 or SB1 CPU core.
As for the microarchitecture of the Loongson, it has about every feature you can find in a book. It's mostly handicaped by the manufacturing process available to the ICT.
