AMD64处理器已内置双内核？

根据Theinquirer的报道，AMD64处理器在设计之初，就已经考虑到双内核设计，目前AMD64处理器仅有1个内核，但是因为已经完成双内核架构设计，因此可以迅速完成双内核AMD64处理器的设计工作。目前，仅有IBM等等少数厂商出品双内核处理器，Intel则在Pentium4处理器上采用超线程形势的双执行单元设计，比较起来，双执行单元需要共享处理器二级缓存，因此在执行效率上弱于双内核处理器。AMD未来双内核处理器当中，每个内核都有独立的HyperTransport总线连接系统请求单元（SRQ）和系统内存，目前AMD仅开放CPU0运作模式，关闭CPU1携同模式，预期AMD会在Intel推出类似产品的同时，发布双内核AMD64处理器。
