Power7是IBM的第一个八核处理器,每个核都能够进行四路并发多线程操作。它的主要架构特征包括具有三级片上高速缓存的高级存储器层次结构;用于最高级别高速缓存的嵌入式DRAM设备;以及新的存储器接口。这种平衡的多核设计可在商业和科学环境中从1个插槽扩展到32个插槽。
The Power7 is IBM's first eight-core processor, with each core capable of four-way simultaneous-multithreading operation. Its key architectural features include an advanced memory hierarchy with three levels of on-chip cache; embedded-DRAM devices used in the highest level of the cache; and a new memory interface. This balanced multicore design scales from 1 to 32 sockets in commercial and scientific environments.
