IBM adds multithreading to Power 5
Building on the technology it introduced with its Power 4 processor, IBM last week announced it will incorporate simultaneous multithreading into its upcoming 64-bit Power 5 processor. With its Power 4 chip, IBM was able to significantly improve performance by incorporating two microprocessor cores on the same dye. The Power 5 also packs two cores on a dye, but each chip will be able to handle two threads simultaneously, increasing performance by 40 percent over its predecessor.
