NEC Corp is readying its first internally produced 64-bit MIPS processors, dubbed ‘T-Rex’, for launch later this year. The company will first produce the 400MHz R1200, built on a 0.15 micron process design rule and then the R1400 next year. The R1400 will have copper interconnects.
According to the Electronic Engineering Times, the R1200 will have a SPECint95 rating of 23, and a SPECfp95 rating of 36. A second version of the chip, the RS1200 S will have a SPECint95 rating of 26 and a SPECfp95 rating of 41, when it arrives later this year.
NEC licensed 64-bit ‘Ruby’ chip technology from MIPS Technologies Inc in January this year. Previous NEC-branded MIPS chips had been largely developed by SGI but NEC took up the baton for the new designs after SGI spun out MIPS last year.
