What ’ s new Intel from “ ”

What ’ s new Intel Pentium ® M Processor Intel ® Centrino ™ mobile technology represents Intel's best notebook technologies designed specifically for mobile computing with integrated wireless LAN capability, breakthrough mobile performance while enabling extended battery life and sleek, easy-to- carry notebook PCs. From “ ”

What ’ s new AMD Desktop Processors Mobile Processors Server Processors Workstation Processors from “

Amdahl ’ s Law

EX:Consider an enhancement that takes 20ns on a machine with enhancement and 100ns on a machine without. Assume enhancement can only be used 30% of the time. What is the overall speedup ?

Amdahl ’ s Law

Performance Super Scalur execute more than one instruction at the same time. Ex:Intel Pentium ® 4 Processor with HT Technology

Performance Super Pipeline cut the instruction into more stages. Ex: Intel Pentium ® 4 Processor has 20-stage pipeline while P-3 has 10-stage pipeline. penalty
