Sun (stock: SUNW) also laid out a new product road map, setting a target for 1.5-GHz UltraSparc III processors in 2001 and successive MPU generations that lead to the introduction of a 2.1-GHz UltraSparc V in 2003. The new UltraSparc III chip is being produced by Texas Instruments Inc., which is using a 0.15-micron process technology to make the RISC processor. The high-end 900-MHz UlraSparc III is being made with copper interconnects, while the initial 600- and 750-MHz processors are being fabricated with aluminum-metal layers. The UltraSparc III has 29 million transistors and seven layers of metal interconnect. The memory controller and system controller functions occupy one-third of the UltraSparc III chip, according to Sun. The 900-MHz copper-based UltraSparc III processor will be ready for system shipments in the first quarter of 2001, said Ron Melanson, senior director of engineering for Sparc processors at Sun. "We are now ramping copper production [at TI] and have 900-MHz processors in-house for qualification of systems," he said Wednesday. Sun, Mountain View, Calif., said its new RISC chip supports a 9.6-GHz/s data rate for cache-address data transfers inside the processor module -- from Level 2 cache memory to the processor. The system has a bandwidth of 4.8 GHz/s from memory to the central processor. This is up to four times the bandwidth of previous Sparc processors, said Sun officials. The new processor runs all applications that also operate on UltaSparc II central processors. Sun rolled out a 600-MHz UltraSparc III for low-end workstations and server applications. Sun itself will use the processor in low-end computer products that will be sold to customers in an auction format over the Internet. The faster systems will be sold through Sun's traditional distribution channels. The UltraSparc III has been designed to link to several hundred processors, and the processor contains a large amount of logic for multiprocessing support. The 9.6-Gbyte/s address bus allows coherent cache storage among a massive array of interconnected processors, according to the vendor. Sun urgently needs the new RISC processor -- a year-and-half late to the market -- to update its five-year old chip architecture. With Intel (stock: INTC) and Advanced Micro Devices Inc. (stock: AMD) planning to introduce 64-bit processors with gigahertz performance next year, Sun needs a new MPU to hold its lead in workstation and server markets.
