纳米科学技术是以许多现代先进科学技术为基础的科学技术,是动态科学(动态力学)和现代科学(混沌物理、智能量子、量子力学、介观物理、分子生物学)。
CPU内集成了以亿为单位的晶体管,这种晶体管由源极、漏极和位于他们之间的栅极所组成,电流从源极流入漏极,栅极则起到控制电流通断的作用。
单个晶体管大小,数字越低做的越小越节能越发热量小,但做的太小晶体管与晶体管过于接近又会造成漏电增大发热量,所以某些人预判制程在3纳米的时候会是晶体管群极限。

对于CPU而言,影响其性能的指标主要有主频、 CPU的位数以及CPU的缓存指令集。所谓CPU的主频,指的就是时钟频率,它直接的决定了CPU的性能,因此要想CPU的性能得到很好地提高,提高CPU的主频是一个很好地途径。
而CPU的位数指的就是处理器能够一次性计算的浮点数的位数,通常情况下,CPU的位数越高,CPU 进行运算时候的速度就会变得越快。现在CPU的位数一般为32位或者64位。

纳米此处应为连线的高度,线宽在一个技术时代里(比如45nm工艺)是可以不断缩小的,而线的高度是不变的。
芯片的制造工艺常常用90nm、65nm、40nm、28nm、22nm、14nm来表示。现在的CPU内集成了以亿为单位的晶体管,这种晶体管由源极、漏极和位于他们之间的栅极所组成,电流从源极流入漏极,栅极则起到控制电流通断的作用。
扩展资料:
栅长越短,则可以在相同尺寸的硅片上集成更多的晶体管——Intel曾经宣称将栅长从130nm减小到90nm时,晶体管所占得面积将减小一半;在芯片晶体管集成度相当的情况下,使用更先进的制造工艺,芯片的面积和功耗就越小,成本也越低。
同样的制程工艺下,实际栅长也会不一样,比如虽然台积电跟三星也推出了10nm制程工艺的芯片,但其芯片的实际栅长和Intel的10nm制程芯片的实际栅长依然有一定差距。并且差距还是不小的。
手机处理器的多少多少纳米其实可以理解为SOC(就是手机处理器)的导线粗细~越细越先进~处理器的复杂程度就越高~这个多少纳米就是制造技术 也叫制成吧~越先进同样构架的SOC发热功耗越低~效能越高 ~更容易跑高频率~就像最近的骁龙625其实性能一般但是16纳米比较先进发热低~省电~但是同样构架的615发热就大性能还不好~ 652也因为28纳米制成倒是没有比同期的650强多少~为因为功耗高不能4大A72全开
这是处理器制作工艺,一般纳米数越小,集成化程度越高,耗电量和发热量都会降低。
