遵循着摩尔定律,CPU的速度每12～18个月就翻一番。伴随着NVIDIA的开发周期,3D图形芯片每6～8个月就推出新一代产品。拥有2GHz的CPU已经不是什么新鲜事儿了,昔日的发烧显卡GeForce4下也已经飞入了寻常百姓家。相比这些部件性能的增加,内存子系统的频率和带宽也在不断提升,但它的性能已不能满足目前CPU和显示芯片数据吞吐量的需求,很快,内存将成为新系统的瓶颈。为了适应更新更快的系统,一时间,各个大厂纷纷发
Following Moore’s Law, CPU speeds double every 12-18 months. With NVIDIA’s development cycle, 3D graphics chip every 6 to 8 months to launch a new generation of products. With 2GHz CPU is nothing new, the old fever graphics GeForce4 has also been flew into the homes of ordinary people. Compared with the increase of the performance of these components, the frequency and bandwidth of the memory subsystem are also increasing. However, its performance can not meet the data throughput requirements of the current CPUs and display chips. Soon after, memory will become the bottleneck of the new system. In order to adapt to newer and faster system, a time, various manufacturers have made
