NEC Corp has announced the VR4400, its version of the R4400 version of the R-series RISC microprocessor family, with over 2m transistors per chip and performance of 113 SPECmarks. NEC is targeting use in workstation, high-end personal computer and multiprocessing system applications. The 64-bit chip uses a 0.6 micron fabrication process, and has an external clock speed of 75MHz and a clock-doubling internal clock speed of 150MHz. Sample shipments have begun in Japan with a sample price of $3,200, and production will be ramped up to 10,000 units per month. US engineering samples are scheduled for April 1993.
