集成显卡与专用显卡:有什么不同?Integrated Graphics vs. Dedicated Graphics: What’s the Difference?


Integrated Graphics
插图: 戈登麦克阿尔平

无论您拥有台式PC还是笔记本电脑,机器中的图形硬件都有两种截然不同的风格。集成图形硬件与PC的其余部分共享PC 内存 。换句话说,它没有自己的RAM。专用图形硬件有自己的内存,甚至可以拥有自己的大脑,称为GPU或图形处理单元。

这对你意味着什么?具有集成显卡的PC受到整个PC所具有的内存量的限制。共享内存意味着你会在很多时候陷入困境,特别是当你在屏幕上有很多图形时。除了内存之外,集成显卡(通常由英特尔识别)通常具有与其专用同类产品相比较差的硬件。即使你不玩游戏,集成显卡和Windows也不喜欢彼此。 Windows Aero用户界面真的很糟糕。在同时做其他事情的同时在电脑上观看电影?算了吧!

具有专用图形的PC具有自己的内存,从512兆字节到几千兆字节不等。在台式PC中,专用图形将在其自己的卡上插入主板。在笔记本电脑上,它仍然是主板的一部分,但旁边会有自己的内存芯片。专用图形的质量差异仍然很大,但总的来说,它的性能会优于集成显卡。拥有自己的RAM意味着您的系统不会使用图形硬件争夺内存。具有自己的GPU的专用图形硬件意味着您不会在PC上争用CPU时间。一些发烧友甚至有两个专用显卡,它们之间有一个桥接器,可以提供额外的图形功能,而且这种方法并不像您想象的那么昂贵。

任何想要多次执行任务,或在PC上观看电影,或做任何与3D图形有关的事情(如游戏)的人都会想要为他们的桌面或具有nVidia的笔记本电脑提供良好的显卡或ATI贴纸就可以了。这是两个主要的图形制造商,这样的贴纸告诉你笔记本电脑上有专门的图形,并将表现良好。

请记住,图形卡升级通常需要新的电源。检查标签上的最低电压要求,并在首次打开机箱时检查电源顶部,看看电源是否足够好。

最后一个想法:如果你有一台低迷的PC,新的显卡可能不是答案。尝试运行我们的九个步骤 ,看看是否可以解决问题而无需升级。祝你好运!

    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.
