现在我们使用的显卡就只有AMD(超微半导体)和Nvidia(英伟达)2家公司开发的显卡,很多朋友对于组装电脑选择显卡上面感到迷茫,到底是选用a卡还是选用n卡,而a卡和n卡又有什么区别呢?下面,小编给大家带来了显卡a卡和n卡的区别介绍。
有些用户在给电脑安装软件时,有时候某些软件对电脑的显卡配置有一定的要求,这时候就需要用户了解自己的电脑的显卡是N卡(Nvidia卡)还是A卡(Ati卡)。那么如何区分电脑显卡呢?下面,小编给大家分享显卡a卡和n卡的区别。
显卡a卡和n卡有什么区别
N卡的优势和A卡的劣势
N卡的GPU中每个流处理器都具有完整的ALU(算术逻辑单元)功能,在发出一条操作指令时每个流处理器都能充分工作.而A卡的GPU中每个流处理器的5个流处理单元都是固定的,不能拆开重组,如果在处理纯4D指令的时候,每个流处理器只能处理一条4D指令,有一个流处理器单元闲置,但却无法加入其他组合来共同工作。

简单地说,一个指令任务派发下来的时候,N卡的GPU是需要1个“人”独立工作即可完成。而A卡的GPU则需要5个“人”。结组工作才能完成ATI的人数虽然多,但这5个“人”中有可能会有4个“人”闲置,因为这4个"人"不具有独立完整的ALU功能,不能执行函数运算,浮点运算和Multipy运算。

N卡的劣势和A卡的优势
ATI的设计也有其显著的特点——浮点运算能力强大。也就是说如果单纯比拼显示核心在浮点运算上的能力的话,可能ATI则要强一些,在目前GPGPU(通用图形处理器)项目应用比较多的科学计算方面,理论上能适应GPU和CPU融台的趋势。

从性价比来说:A卡会更具有性价比。2012年前A卡在影音和图形设计方面会比N卡来得出色。而N卡在游戏性能方面则是胜出。当然对我们一般电脑使用者(不追求专业)来说,两款显卡其实区别不是那么大。
从游戏的视角来说:建议选择N卡,(2012年前)因为大部分游戏只针对N卡做了优化。有句话这么说,玩游戏,N卡孔武有力,A卡色泽艳丽;N卡像男淫,A卡像女淫。不过这句话是很多年前讲的,以前A卡的显卡驱动不完善,导致游戏方面表现乏力,现在情况已经大幅好转。
这两种从设计看高清和玩游戏选择相应的显卡的说法都是之前遗留下来的,导致现在大部分人还是这么认为。其实最新的N卡与A卡的区别在游戏中表现是各有优劣,在多数游戏测试中都是互有胜负,平分秋色。

a卡和n卡哪个好?
各有特点,看所需要。
A卡是AMD显卡 N卡是英伟达的显卡。
一般多做专业作图设计都用A卡,A卡的色彩度好,N卡相对来讲没有A卡的色彩度好,但是游戏性好一点,同等级别的显卡A卡软件跑分要强于N卡 ,相差不会太大,略高一些,但是游戏性能方面N卡有物理加速,N卡会比A卡表现的更好,N卡的驱动成熟,针对游戏这块很下工夫,A卡的驱动,针对游戏这儿容易出问题,所以喜欢游戏的人,大多会选择N卡,稳定性好一点,如果你是个硬件高手懂得怎么调配这些东西,A卡N卡对你来讲就都一样了,知道自己的需求,如果是小白就建议直接上N卡,什么都一样玩就可以了。

总的来说N卡和A卡虽然架构有别,但为了与各类软硬件兼容,都是遵循一定的标准进行设计,所以在性能的实现上都是一样的。
