iBookG4ベンチマーク

14インチのコンボモデルをXbench v1.0で測定しました．iBookG3@600MHz（Dual USB）と比べて，メモリーがほぼ3倍，ディスクがほぼ2倍の速度を叩き出してましてますね．描画速度は1.5倍程度．もっと速度出ると思ったんですけどねぇ．
体感速度は2倍くらいでしょうか．Windows（Celeron@1.2GHz）と比べるとMacの方が遅く感じます．．．でもいいんです．静かだし布団の上でも使えるし*1．
iBookG3では普段，完全に無音だったのですが，G4になってから空冷かHDDかの音が常に聞こえます．我慢できる範囲内なのでいいですけどね．

*1:Winノートの多くは底面に凹凸があったり吸気/排気窓があったりして，布団の上で使えないんですよ．
