Performance Characterization of Mobile-Class Nodes: Why Fewer Bits is Better

Mobile-class nodes---small, low power netbooks with limited available memory---are becoming increasingly popular in the personal computing market. Though originally designed with a 32-bit processor, these netbooks are now being shipped with a 64-bit mobile-class processor. We explore a variety of performance differences between mobile-class processors and server-class processors. Using the SPEC CPU2006 integer benchmarks, we show that the mobile-class processors do not benefit from the move to 64 bits like server-class processors do. We show that the limited memory available on these mobile-class nodes, along with the in-order nature of the processors, produce the greatest disparity in performance.
