What is a dual core processor? What is a dual-core processor?

Dual-core processors are the integration of two computing cores on a single processor to increase computational power. The concept of "dual core" was first proposed by IBM, HP, Sun and other high-end server vendors supporting RISC architecture, but because of the high cost and narrow application of the RISC architecture, it did not attract wide attention.

The concept of "dual-core", which has recently become hot, mainly refers to dual-core technology based on X86 open architecture. In this regard, the leading manufacturers are mainly AMD and Intel two. Among them, the two ideas are different. AMD has been designing from the outset to take into account the support of multiple cores. All components are directly connected to the CPU, eliminating system architecture challenges and bottlenecks. The two processor cores are directly connected to the same kernel, and the core is communicated with the chip speed, further reducing the latency between the processors. Intel uses multiple cores to share the front-end bus. Experts believe that AMD's architecture for more easy to achieve dual-core and multi-core, Intel's architecture will encounter multiple kernel contention bus resource bottlenecks.
