  The Crusoe is a family of x86-compatible microprocessors developed by Transmeta. Crusoe was notable for its method of achieving x86 compatibility. Instead of the instruction set architecture being implemented in hardware, or translated by specialized hardware, the Crusoe runs a software abstraction...
  
  )

Thanks to its unique architecture Elbrus 2000 can execute up to 23 instructions per clock so even with its modest clock speed can compete with much faster clocked superscalar

Superscalar

A superscalar CPU architecture implements a form of parallelism called instruction level parallelism within a single processor. It therefore allows faster CPU throughput than would otherwise be possible at a given clock rate...

Elbrus 2000 Highlights

produced	2005
process	CMOS 0.13 µm 130 nanometer The 130 nm process refers to the level of semiconductor process technology that was reached in the 2000–2001 timeframe, by most leading semiconductor companies, like Intel, Texas Instruments, IBM, and TSMC....
clock rate Clock rate The clock rate typically refers to the frequency that a CPU is running at.For example, a crystal oscillator frequency reference typically is synonymous with a fixed sinusoidal waveform, a clock rate is that frequency reference translated by electronic circuitry into a corresponding square wave...	300 MHz
