NVIDIA前不久推出Ge Force GTX1080的强悍性能令人印象深刻,而造就其澎湃性能动力的源泉,除了新工艺、新核心以外,一项名为GDDR5X的显存技术也是功不可没。GPU对带宽的渴求CPU芯片自身就内置多级高速缓存,可有效缓解与内存进行数据交换的中转时间。作为PC系统中的另一个计算核芯,GPU由于缺少内置高速缓存的设计,GPU与显存之间进行数据交换的效率(带宽),将对GPU自身性能的发挥产生决定性影响。因此,在GPU核芯越来越强的当下,显存带宽也需要同步革新。 NVIDIA introduced the impressive performance of the GeForce GTX1080 not long ago, and the source of its surging performance power. In addition to the new technology and new core, a memory technology called GDDR5X is also contributed. GPU’s thirst for bandwidth CPU chip built-in multi-level cache itself, which can effectively ease the transit time with the memory for data exchange. As another computing core in a PC system, the GPU’s lack of built-in cache design and the efficiency (bandwidth) of data exchange between GPU and video memory will have a decisive impact on the performance of the GPU itself. Therefore, the GPU core is more and more nowadays, memory bandwidth also need to synchronize innovation.
