你是否拥有台式电脑或笔记本电脑,在你的机器的图形硬件有两个非常明显的味道。集成显卡的硬件共享电脑的内存与您的电脑的其他部分。换句话说,它没有其自己的RAM。专用的图形硬件有它自己的存储器,甚至可以有其自己的脑,称为GPU或图形处理单元。

这是什么意思吗?采用集成显卡的PC是由你的整个PC具有的内存量的限制。共享内存意味着你将要陷入了很多时间,尤其是当你已经得到了很多在屏幕上的图形。除了内存,集成显卡(通常由英特尔是确定的),通常具有较低的硬件给专门的表兄弟。即使你不玩游戏,集成显卡和Windows不喜欢对方。 Windows Aero用户界面确实受到影响。和PC上观看电影,而在同一时间做别的事情?算了吧!

专用的图形的PC机都有自己的内存,从512兆字节到数千兆字节。在台式PC,专用的图形将是自己的卡插在主板上。在笔记本电脑上,它仍然是主板的一部分,但将它旁边自己的内存芯片。专用的图形仍然可以在质量上千差万别,但总的来说,表现将优于集成显卡。有它自己的内存意味着你的系统不争取与图形硬件内存。有自己专用的GPU图形硬件意味着你不会打你的PC 的CPU时间,无论是。有些爱好者甚至有两个专门的图形卡提供额外的图形动力它们之间的桥梁,这种方法并不像你想象的那样昂贵。

谁想要多任务很多,或在电脑上观看电影,或做任何事情有3D图形(如游戏)做会希望为自己的桌面显卡好,或者说有一个NVIDIA或一台笔记本电脑它ATI的贴纸。这是两个主要的显卡厂商,而这样的贴纸告诉你笔记本电脑已经板载专用的图形,并会表现良好。

请记住,一个显卡升级往往需要一个新的电源。检查最低电压要求,标签和检查电源的顶部,当你第一次打开你的情况,看看你的电源是不够好。

    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.
