The Toshiba / MIPS R10000 Processor
The R10000 'T5' is the first single-chip 4-issue superscalar processor by MIPS, introduced in 1995. It gave a 70 to 100% performance increase over the R4400 at 250 MHz, previously the most powerful MIPS processor. The R10000 CPU was used in NEC supercomputers and various SGI machines like the Indigo2, O2, Octane, Octane 2, Onyx, Onyx 2, Origin and Challenge.
