顯卡的核心頻率是指顯示核心的工作頻率,其工作頻率在程度上可以反映出顯示核心的性能,但顯卡的性能是由核心頻率、流處理器單元、顯存頻率、顯存位寬等多方面的情況所決定的,因此在顯示核心不同的情況下,核心頻率高並不代表此顯卡勁。比如GTS250的核心頻率達到了750MHz,要比GTX260+的576MHz高,但在性能上GTX260+要強於GTS250。在同樣級別的芯片中,核心頻率高的則性能要強一些。主流顯示芯片只有AMD和NVIDIA兩家,兩家都提供顯示核心給第三方的廠商,在同樣的顯示核心下,部分廠商會適當其產品的顯示核心頻率,使其工作在高於顯示核心固定的頻率上以達到更高的性能。 顯存頻率
顯存頻率程度上反應著該顯存的速度,顯存頻率的高低和顯存類型有非常大的關係。
顯存頻率與顯存時鐘周期是相關的,二者成倒數關係,也就是顯存頻率( MHz)=1/顯存時鐘周期(NS)Xl000。但要明白的是,顯卡制造時,廠商設定了顯存實際工作頻率,而實際工作頻率不等於顯存大頻率,此類情況較為常見。
顯示存儲器
顯示存儲器簡稱顯存,也稱為幀緩存,顧名思義,其主要功能就是暫時儲存顯示芯片處理過或即將提取的渲染數據,類似於主板的內存,是衡量顯卡的主要性能指標之一。
顯存與係統內存一樣,其容量也是越多越好,圖形核心的性能越強,需要的顯存也就越大,因為顯存越大,可以存儲的圖像數據就越多,支持的分辨率與顏色數也就越高,遊戲運行起來就更加流暢。
主流顯卡基本上具備的是6GB容量,一些中顯卡則配備了6GB、8GB的顯存容量。
顯存類型
顯存類型即顯卡存儲器採用的存儲技術類型,市場上主要的顯存類型有SDDR2、GDDR2、GDDR3和GDDR5幾種,但主流的顯卡大都採用了GDDR3的顯存類型,也有一些中顯卡採用的是GDDR5,與DDR3相比,DDR5類型的顯卡擁有更高的頻率,性能也更加強大。
