Toshiba America Electronic Components Inc is now shipping its 200MHz version of the MIPS Technologies Inc R4400 microprocessor, saying it was the first to get a 200MHz part to MIPS for certification. The new chip is fabricated in 0.3 micron CMOS and has a die size of 134 square millimeters integrating 2.3m transistors, and based on MIPS’ new Application Benchmark Suite of real-time 32-bit Windows NT applications, it performs up to three times faster than the fastest available Pentium processor, the P54C at 90MHz. It has 16Kb instruction and 16Kb data cache, and comes in three versions, all 3.3V. The R4400PC supports primary cache for desktop and high-performance embedded control work. The R4400SC supports primary and secondary cache for workstations and servers. The R4400MC adds multiprocessing support. Samples June, volume in third quarter at $1,600, $1,950 and $2,150 respectively for 10,000 or more.
