Atom330の実力 – B-LOG

Atom330の実力

サークルでサーバ用途に組んだAtom330マシン(D945GCLF2)でFFMpegを使用して動画のエンコードをしてみた。

手持ちのAthron64 3000+なマシンとほぼ同じ速度だった。

低消費電力でマルチスレッド指向なAtomはサーバ向きだと思っていたけど、いろんな所でベンチマークを見るとマルチメディア性能が非常に高い。

それはSSE3が搭載されていることからも見て取れるのだけれど、ねらったところにぴっしりはまっているなと言う印象。細かいところのストラテジーの勝利。

unixbench (v4.1)ではshell scriptの性能がCoreに匹敵していて驚いた。

makeに関しては期待したほど速くないという印象。「マルチコアCPUだとmake worldが10分で終わる!」なんて根も葉もない噂を聞いた後だったからかもしれない。ただ、FreeBSD 7.1でmake worldしたのは初めてなので他のマシンでやってみて数字を出さないことには何ともいえないはず。
