几款不同的CPU一些数据--备查

几款不同的CPU一些数据–备查

背景

方便大家对不同的CPU混个脸熟，有个整体概念。本来发布在知识星球，但是知识星球上格式看起来太影响阅读效率了，所以特意拿出来发到博客上

简单查看CPU我一般用 lscpu(默认自带) 命令，或者用复杂点的工具：hwloc 工具安装：

1
yum install hwloc -y

安装后生成结构图片命令：

1
lstopo --logical --output-format png > kunpeng_920.png

生成字符结构，不要图片：

1
lstopo-no-graphics

后面展示的都算是整体机构，所以还会附带有内存怎么接(一个多少条，每条多大，一个Numa node插了几个物理内存条)，这些我博客上都有，就不展开了。一般都是对称的(每个node、socket对称，不对称肯定发挥不出来好性能)

intel E5 2682

大概是Intel 2012年的主流服务器CPU

作业：7260和7280的区别是？为什么搞了这两个差异很小的CPU？

//继续在7280上看看L3的大小和共享，能够识别他的Die设计理念

//7280上 L3 由8个超线程，也就是4个物理核共享
#cat cache/index3/shared_cpu_list
0-3,64-67      //就这里核数不一样
#cat cache/index3/size
8192K          //L3大小和7260一样

还记得7260是3个物理核共享一个8M的L3吧，计算机的世界大多是1、2、4、8，看到3我就觉得有些别扭。评论区告诉我为什么会搞出3个核这样一个奇葩设计？（星球图解专栏里有答案）

AMD 7T83

整机256核，一路128超线程，单CPU 64个物理核，很猛了

总结

希望通过具体又不同的CPU案例展示，让你对CPU的结构有一些整体认识

请问：Hygon C86 7260 这块CPU每个Die的L2、L3分别是多大？

请思考，最近10年CPU的性能没啥大的进不了(如下图红色部分，每年3%)，但是这么多年工艺还在进步，集成的晶体管数量
