A卡好还是N卡好 A卡和N卡的区别(2012版)

A卡好还是N卡好 A卡和N卡的区别(2012版) 曾经有不少网友问过小编“A卡好还是N卡好”这个问 题 快递公司问题件快递公司问题件货款处理关于圆的周长面积重点题型关于解方程组的题及答案关于南海问题 ，不过随着近年来，显卡性能大幅提升，中高端显卡对于多数用户来说已经处于过剩阶段，因此问a卡好还是n卡好的网友也越来越少了。今天又有一朋友问到，有点无语了，下面我们还是来看看2012年最新的关于A卡与N卡区别对比吧。看完大家就知道A卡好还是N卡好了。 >.怎么看电脑显卡 如何看显卡性能如何 N卡和A卡两家架构问题要深究就得写一本书了。在DX9以前的时代，两家的架构主要由像素单元、顶点单元、纹理单元、光栅单元组成，一个渲染流程的所有单元绑在一起组成一条渲染管线，管线越多，性能就越强。而游戏中的指令以4D指令居多(像素有RGBA，顶点有XYZW)，这些单元就被设计成了一次能处理4D指令的处理器，对于当时的游戏环境来说这种架构效率很高。但到了DX9后期甚至DX10时代，游戏中的1D、2D、3D、4D指令开始频繁混合出现，像素与顶点的渲染量比例也有了改变，原先的架构就变得效率低下了，比如一个处理单元一次能处理4D运算，当碰到1D运算时就只用到4/1的资源，剩下3/4的资源就闲置掉了，相当于效率降低了4倍。而有些游戏的像素渲染量明显多于顶点，那么这些绑在一起数量比例固定的单元就效率低下了，比如像素吃力的时候，顶点可能比较空闲，非常浪费资源。为了解决这个问题，NV和ATI都对架构进行了改进，但都治标不治本。这时候重新设计架构成为了必然，所以，从DX10时代起，两家的架构就起了翻天复地的变化。 当两家DX10产品面市后，人们惊奇的发现，竟然是两种不同的架构。 N卡的架构思路很简单，用强大的前端处理器把所有指令拆分成一个个1D指令，而下面所有处理单元都变成了1D单元(流处理器)，这些流处理器都能当做像素和顶点单元来使用，每个单元都能独立收发指令，这样不管碰到什么类型的指令都能“一拥而上”，效率几乎达到100%的理想程度，是标准的线程级并行架构，也是追求高效率的理想架构。 school)], 4 4 house building as well as more than 1000 copies of books, more than 10 kinds of collection of newspapers and magazines, fires burnt down.
