あけましておめでとうございます。毎年が魚年です。
手元のデスクトップPCのベンチマークをUnixBenchでとってみたのでメモ。

6年戦士の自宅旧PCがLive USBなのは、処分前でディスクをすでに抜いてしまっため。File Copy関連は参考にならない(低く出ているはず)です。
いずれもCPU scaling governerをperformanceにしています。
% sudo cpufreq-set -g performance
なおIntel CPU搭載のUbuntuであればperformanceとpowersaveモードが利用可能ですが、powersaveにしてもスコアは誤差レベルでしか変わりませんでした。

アイドル時は800MHzまでクロックが落ちるのでいいですね。
CPUファンをちょっと良いやつにしてみたので、CPU温度もアイドル時30度・UnixBench時や動画並列エンコードなど最大負荷をかけても50度にはいかない程度にとどまるので、とても安心感あります。空冷でもちゃんとしたやつならハイエンドCPUに対しても十分みたいですね。
この構成で1070Tiを載せてパーツ代全部で税込み17万円ぐらい。BTOだったら20万を下回ることはない構成(2018年12月現在)なので自作だとやはり結構抑えられますね。PC組むの久々なのでまる1日仕事にはなりましたが。

所感
i5 3570→i7 9700Kであっても倍精度演算(Whetstone MWIPS)が実はコア当たりだと全然速くなってないらしいのが意外。SIMDでなければ1FLOP/1clockに漸近していくからかな?
OS関連、プロセスとかシステムコールとかが圧倒的に速くなってるみたい。日頃の動作で差を感じることは多そう。
