Intel的并不是在一个芯片上集成四个硬件核心，而是采用双芯片的组合方式，Intel只需要生产双核Core 2 Duo处理器，然后再将芯片封装在一起，成为四核心的Core 2 Quad。不过，Core 2 Quad 双芯片四核设计存在问题，虽然Core 2 Duo芯片内部的双核心可以共享二级缓存，具有较高的协作效率-Intel is not in a hardware chip four-core, instead of using the two-chip combination of the way, Intel only need to produce dual-core Core 2 Duo processor, and then chip package together, become a four-core Core 2 Quad. However, Core 2 Quad two-chip quad-core design problems, although the Core 2 Duo dual-core chip can be shared secondary cache, in collaboration with high efficiency
