集成顯卡與專用顯卡:有什麼不同?Integrated Graphics vs. Dedicated Graphics: What’s the Difference?


Integrated Graphics

你是否擁有台式電腦或筆記本電腦,在你的機器的圖形硬件有兩個非常明顯的味道。集成顯卡的硬件共享電腦的內存與您的電腦的其他部分。換句話說,它沒有其自己的RAM。專用的圖形硬件有它自己的存儲器,甚至可以有其自己的腦,稱為GPU或圖形處理單元。

這是什麼意思嗎?採用集成顯卡的PC是由你的整個PC具有的內存量的限制。共享內存意味著你將要陷入了很多時間,尤其是當你已經得到了很多在屏幕上的圖形。除了內存,集成顯卡(通常由英特爾是確定的),通常具有較低的硬件給專門的表兄弟。即使你不玩遊戲,集成顯卡和Windows不喜歡對方。 Windows Aero用戶界面確實受到影響。和PC上觀看電影,而在同一時間做別的事情?算了吧!

專用的圖形的PC機都有自己的內存,從512兆字節到數千兆字節。在台式PC,專用的圖形將是自己的卡插在主板上。在筆記本電腦上,它仍然是主板的一部分,但將它旁邊自己的內存芯片。專用的圖形仍然可以在質量上千差萬別,但總的來說,表現將優於集成顯卡。有它自己的內存意味著你的系統不爭取與圖形硬件內存。有自己專用的GPU圖形硬件意味著你不會打你的PC 的CPU時間,無論是。有些愛好者甚至有兩個專門的圖形卡提供額外的圖形動力它們之間的橋樑,這種方法並不像你想像的那樣昂貴。

誰想要多任務很多,或在電腦上觀看電影,或做任何事情有3D圖形(如遊戲)做會希望為自己的桌面顯卡好,或者說有一個NVIDIA或一台筆記本電腦它ATI的貼紙。這是兩個主要的顯卡廠商,而這樣的貼紙告訴你筆記本電腦已經板載專用的圖形,並會表現良好。

請記住,一個顯卡升級往往需要一個新的電源。檢查最低電壓要求,標籤和檢查電源的頂部,當你第一次打開你的情況,看看你的電源是不夠好。

最後一個念頭:如果你有一個緩慢的PC,一個新的顯卡可能沒有答案。試圖通過我們的運行九個步驟 ,看看你是否可以解決該問題,而無需進行升級。祝你好運!

    Graphics cards are not always the answer, since you won’t need them 24/7. I personally would choose 16 GB RAM over 12 GB RAM + 2 GB VRAM (as an example) in a computer. However gamers who need 16 GB all the time should get a graphics card.

  • Agree with you here Brett. A RAM upgrade is always a great first place to go for an upgrade, especially considering how cheap it is.

    my laptop contain intel hd graphic 4000 and amd radeon 8600 garaphics in this both graphic i dnt what is what .in my laptop specifications it was written i have 1 gb dedicated graphic iam aa video gamer i need to upgrade the the graphics to at least 2 gb or 3gb can i upgrade help me

    Buying cheap 2or3or4 GB graphics card isn’t gonna benefit and the motto is,higher the cost,Better the card.and also look for the number like,for nvidia-gt610,gt620…gtx650gtx660….higher the last two nos, better the performance(if you have a desktop).

    In a laptop,it is mere impossible to upgrade your graphics and the better choice is to sell your old one and buy a new one with more specs.

    How about the AMD radeon HD? is it good or not?

  • VR

    Not all of them. The lower/ cheaper ones are crappy.But the higher ones (whch have been give new names under R series) awesome.A R7 can play most games with medium to ultra with not much fps drop. But still, higher the numbers, better the performance. ie; a R7 270 wont be a match to a R9 290X. So, if you budgets are tight, dont buy and HD series or nvidia gt series, instead get a little more money and buy atleast a R7 ( and if you are lucky, you may find a second hand R9 that someone havent used cause it wont work in their pc for the price of a R7, that’s how i got my R9 290X) And for those who wants to buy a gtx 690, think about R9, same performance, lower priced. Amd i doing a great jb with their cheap yet the most powerful ones and gfx cards that are also cheap and does the work it is made for. nb: Amd processors are way better than intel ones, just compare an i7 and any of the processor from Amd FX series.
