cpufetchというscreenfetchインスパイアな感じのcpu情報表示ツールを見かけたので試してみました．
$ git clone https://github.com/Dr-Noob/cpufetch
$ cd cpufetch
$ make
$ ./cpufetch -s retro

###############################標準のスタイルでテキストで貼り付けると真っ白になるので retro です．通常の実行結果は以下に．
Linux以外でもWindows/macOS/Android(termux)でも動作するようです．
neofetch/screenfetch等はシステムの情報を表示しますがcpufetchはcpu情報に特化しています．未だサポートcpuは多くないようです．
/proc/cpuinfo, lscpu, lshw -class cpu とかのほうが実用的だと思いますが，楽しいので．
