Intel Corp. coined the name "NetBurst" for its new 400-MHz front-side-bus IA-32 architecture for Pentium 4 and future processors.
Unlike the P6 architecture, the new FSB divides each clock cycle to achieve a much higher speed. Albert Yu, senior vice president of Intel's architecture group, said the new architecture will allow the arithmetic logic unit to run at different speeds.
The SIMD bus has also been increased from a 64- to a 128-bit word width to offer the highest streaming graphics and audio performance with the most security. Yu reiterated that Pentium 4 will be introduced in the fourth quarter.
Asked if the 1.5-GHz Pentium 4 performance at launch will be higher than the existing 1-GHz Pentium III because of the much deeper 20-stage pipeline, Yu said the higher frequency alone will assure performance greater than Pentium 3.
He demonstrated a prototype Pentium 4 chip that achieved 2-GHz speed and said 1-GHz Xeon Pentium III processors are now shipping to OEMs. Intel has shipped 6,000 prototype 64-bit Itanium processors to software developers, who have committed to porting more than 350 applications to Itanium, Yu said.
"We are working toward a Q4 '00 time frame to launch Itanium."
