The SuperSPARC is a microprocessor that implements the SPARC V8 instruction set architecture (ISA) developed by Sun Microsystems.

It was fabricated by Texas Instruments (TI) at Miho, Japan in a 0.8 micrometre triple-metal[1] BiCMOS process.

The SuperSPARC+ was developed to remedy some of the design flaws that limited the SuperSPARC's clock frequency and thus performance.

The SuperSPARC-II, introduced in 1994, was a major revision with improvements that enabled the microprocessor to reach 85 MHz in desktop systems and 90 MHz in the more heavily cooled SPARCserver-1000E.

The SuperSPARC-II was replaced in 1995 by the 64-bit UltraSPARC, an implementation of the 64-bit SPARC V9 ISA.
