UnixBench 自分の常用端末でも試してみた

PCでUnixBench

そういえばNanoPi NEO/NEO2をUnixBenchで測ったけど、普通のPCだとどれくらいだろうと思ったので見てみた。

Pentium N3700のPC

まずは常用している端末。これはPentium N3700 1.6GHzというCPUを搭載しているPC。以前にルーター用として購入したASRock N3700-ITXが退役したお下がり。人に言わすと「何？その苦行」レベルの性能だけど、ブラウザでネット見てメールしてエディタで何か書く程度だとほとんど不満なく使えてんるだけどねぇ。

NanoPi NEO2のインデックススコア(前回)がシングルで298.9、4パラレルで771.2だったので単純にその数値で比較するとどちらも2倍に僅かに届かない程度。つまりオイラのPCはNanoPi NEO2の2倍速いんだぜってこと。

NanoPi NEO(無印)と比べてみた。
NanoPi NEOのインデックススコア(前回)がシングルで164.1パラレルで429.0だったので単純にその数値で比較するとどちらも共に3.48倍。つまりオイラのPCはNanoPi NEOの3.5倍も速いんだぜYeah!ってこと。

Core i3 2120TのPC

殆ど仕事らしい仕事をしていないサーバでも試してみた。
CPUはIntel Core i3-2120T 2.60GHz。これは、たしかSandy Bridge世代のi3の省電力版。要するにi3とか名乗っていてもドラクエの最初に出てくる敵のスライムなみのザコ。

全く期待してなかったけど本当に良くない。シングルでは748.3ということなのでN3700よりは流石にマシだけど、4パラレルだと1367ということでN3700の1496.5と比較して約9%低いスコアとなっている。
i3は2コア4スレッドなので4パラレルで良い筈。ちなみに2パラレルだとインデックススコアは1072.9だった。

もうちっとマシなCPUでも試したかったけど空いてなかったので今回はこれだけ。

っていうか俺のPCって15ドルのおもちゃの2倍の性能しかないのかよ・・・orz
