在一个集成电路中，多个芯片、共享内存以及互连形成了一个紧密集成的多处理核心(参见图4)。

On a single integrated circuit, multiple chips, Shared memory, and an interconnect form a tightly integrated core for multiprocessing (see Figure 4).

CMP 紧密耦合的本质使处理器与内存之间的物理距离很短，因此可提供最小的内存访问延迟和更高的性能。

The tightly-coupled nature of the CMP allows very short physical distances between processors and memory and, therefore, minimal memory access latency and higher performance.

虽然这个小小的接口对大部分显示工作来说并不是什么大问题，但它却无法应付CPU、GPU和内存紧密结合的并行运算。

While that little port isn't a big problem for most visual jobs, it's a hassle for parallel computing that works the CPU, GPU, and memory all in close association.
