CPCI规范自制定以来，已历经多个版本。
最新的PICMG3.0所规范的CPCI技术架构在一个更加开放、标准的平台上，有利于各类系统集成商、设备供应商提供更加便捷快速的增值服务，为用户提供更高性价比的产品和解决方案。
PICMG3.0标准是一个全新的技术，与PICMG2.x完全不同，特别在速度上与PICMG2.x相比，PICMG3.0速度每秒可达2Tb。
PICMG3.0主要将应用在高带宽电信传输上，以适应未来电信的发展，PICMG2.x则仍是目前CPCI的主流，并将在很长时间内主宰CPCI的应用。
三、CPCI的应用
CPCI所具有高开放性、高可靠性、可热插拔（HotSwap），使该技术除了可以广泛应用在通讯、网络、计算机电话整和（ComputerTelephony），也适合实时系统控制（RealTimeMachineControl）、产业自动化、实时数据采集（Real-TimeDataAcquisition）、军事系统等需要高速运算、智能交通、航空航天、医疗器械、水利等模块化及高可靠度、可长期使用的应用领域。
由于CPCI拥有较高的带宽，它也适用于一些高速数据通信的应用，包括服务器、路由器、交换机等。
