RISCS AGAIN WHITEWASH COMPLEX INSTRUCTION SET CPUS IN SECOND ROUND OF SPECMARKS

The latest benchmarking figures just released by SPEC – the Systems Performance Evaluation Co-operative – show that Motorola has usurped MIPS’ pole position in the Unix RISC system performance stakes – the first round of results is in CI No 1,282. The 88000-based Delta Series Model 8612, using Diab Data AB’s D-CC/88K C compiler, achieved a SPECmark of 17.8, besting MIPS Computers’ M/2000 machine by 0.2 of a SPECmark. However MIPS’ RC6280 system based on the new R6000 chip set and rated at 55 MIPS – not included in the tests as yet – is sure to regain the top spot when it comes to be benchmarked. Data General and Solbourne Computer Corp weighed in with their first results Solbourne making a strong showing at fifth place with its latest Series 5 Sparc machine. Most SPEC members have upped the compiler and cache configurations on their respective machines to improve on their previous results, although the processor architectures and clock speeds remain the same.

Newcomers to SPEC are Du Pont Co, Intel Corp, Solbourne and Unisys Corp, bringing membership up to 16 – and SPEC has set up three subcommittees in multiprocessing, commercial processing and input-output to develop benchmarks covering all systems. The suite of benchmark tests – Release 1.0 – is available from SPEC for $450.
