▸创新点1:采用32纳米高k金属栅极工艺技术,显著提升晶体管密度和能效比,相比前代45纳米工艺,在相同功耗下实现更高核心频率(如接近4 GHz)和更大缓存容量(12 MB L3缓存)。
▸创新点2:引入Turbo Boost动态频率调节技术(系统创新),通过实时监测工作负载和温度,智能提升单核/多核频率(最高提升至4 GHz),兼顾高性能与能效,特别适用于移动和桌面场景。
▸创新点3:支持低电压DDR3内存控制器(电路创新),在保持兼容性的同时降低内存子系统功耗,结合多核架构优化,使服务器处理器在1.17B晶体管规模下仍能控制芯片面积(240 mm²)。
▸创新点4:采用多芯片模块封装技术(方法创新),将处理器与45纳米芯片组通过专有互连集成,优化I/O性能并降低延迟,为客户端平台提供灵活的配置方案。

Abstract—Westmere is the latest IA processor family for mo-
bile, desktop and server market segments, implemented on Intel’s
second-generation high-k metal gate 32 nm process. Westmere not
only increases core count, cache size, and frequency within the
previous generation’s power envelope, it also provides further im-
provements in power efficiency, feature set, and support for co
