Core i7 7700Kとi7 9700KのUnixBench

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。

項目 自宅新PC 業務PC 自宅旧PC
CPU i7 9700K

OS Ubuntu MATE 18.04.1 Ubuntu MATE 18.04.1 Ubuntu MATE 18.04.1 (Liveモード)
GCC 7.3.0 7.3.0 7.3.0

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。
