显卡的核心频率是指显示核心的工作频率,其工作频率在程度上可以反映出显示核心的性能,但显卡的性能是由核心频率、流处理器单元、显存频率、显存位宽等多方面的情况所决定的,因此在显示核心不同的情况下,核心频率高并不代表此显卡劲。比如GTS250的核心频率达到了750MHz,要比GTX260+的576MHz高,但在性能上GTX260+要强于GTS250。在同样级别的芯片中,核心频率高的则性能要强一些。主流显示芯片只有AMD和NVIDIA两家,两家都提供显示核心给第三方的厂商,在同样的显示核心下,部分厂商会适当其产品的显示核心频率,使其工作在高于显示核心固定的频率上以达到更高的性能。 显存频率
显存频率程度上反应着该显存的速度,显存频率的高低和显存类型有非常大的关系。 
显存频率与显存时钟周期是相关的,二者成倒数关系,也就是显存频率( MHz)=1/显存时钟周期(NS)Xl000。但要明白的是,显卡制造时,厂商设定了显存实际工作频率,而实际工作频率不等于显存大频率,此类情况较为常见。 
显示存储器
显示存储器简称显存,也称为帧缓存,顾名思义,其主要功能就是暂时储存显示芯片处理过或即将提取的渲染数据,类似于主板的内存,是衡量显卡的主要性能指标之一。 
显存与系统内存一样,其容量也是越多越好,图形核心的性能越强,需要的显存也就越大,因为显存越大,可以存储的图像数据就越多,支持的分辨率与颜色数也就越高,游戏运行起来就更加流畅。 
主流显卡基本上具备的是6GB容量,一些中显卡则配备了6GB、8GB的显存容量。 
显存类型
显存类型即显卡存储器采用的存储技术类型,市场上主要的显存类型有SDDR2、GDDR2、GDDR3和GDDR5几种,但主流的显卡大都采用了GDDR3的显存类型,也有一些中显卡采用的是GDDR5,与DDR3相比,DDR5类型的显卡拥有更高的频率,性能也更加强大。
