英特尔®安腾®平台企业级新技术 技术 描述 益处 节约功耗技术: DBS Demand Based Switching, I/O: PCI-EXPRESS, FBD, DDR 2 DBS: OS changes CPU power based upon utilization DBS: Reduced energy consumption with lower utilization for savings up to 30% Serial I/O, removing bottlenecks caused by arbitration of parallel I/O Increased performance, RAS and lower power. Headroom to accommodate LAN upgrade opportunities 分区虚拟化技术: Virtualization Technology Processor includes “hooks” VMM talks to hooks Easier and more robust way for virtualized partitions to support consolidation 稳定性技术: Pellston Technology to disable L 3 cache lines that exhibit hardware failures Brings Itanium family to/beyond RISC & mainframe reliability features. Helps to reduce risk of ECC errors in L 3 动态性能提升技术: Foxton Technology Processor feature which boosts system performance based on power consumption Dynamic processor frequency increase up to ten percent when application power consumption provides headroom 并行性能技术: Multi-Threading Boost system performance by doing more work with every clock cycle Increased performance, more throughput, better price / performance 双核心技术: Dual-Core / Multi-Cores, cache, interconnect and arbitration logic within single die Increased performance, more throughput, better price / performance; no recompilation Comparisons referenced are in relation to Intel product offerings today (as of May
