今回は自宅のPentium4 2.0GHzでテストしてみました。
これを基準にその比を見ると概ねのPentium4相当のクロックが見れます。
(Pentium4XEを基準にするともう少し小さい値になると思います。)

Pentium4 2.0GHz 32:12=1932(s) 2.00 (kernel noSMP j1)
NX1750 39:14=2354(s) 1.64 (kernel SMP)
Opteron280 2.4GHz 16:20=980(s) 3.94 (SMP j1)
Xeon2.8GHz 23:43=1423(s) 2.72 (noSMP)
Xeon2.8GHz 21:55=1315(s) 2.94 (SMP)

自宅のCeleron900MHzの方を新しくしようと思っているところ
ですが、自分の行っている数値計算に限るとPentium系の方が
Intelコンパイラーを用いた場合に圧倒的に高速な場合もあり
選択が悩ましいところです。いまのところはTurion64にしよう
と思ってはいます。自宅の場合はいかに静かなLinuxBoxにする
かですので。

以下テスト結果
