ヤフオクで、130W電源が安く手に入ったのでThinkCentre M75q-1 Tinyにつけてベンチマークを測りなおしました。
Dell ACアダプター 130W DA130PE1-00 未使用品
まずは、Windows10環境で Cinebench R15とR20から。CPUは微増で OpenGLが少し上がった感じ。
Cinebench R15
130W → 41.57
65W → 35.77
もっと上がると思ったんですが、約1.2倍くらいしかあがりませんでした。
Cinebench R20
130W → 1715
65W → 1658
Cinebench R20は、 OpenGL がないので1.03倍という結果。
ついでに、Linux環境でUnixBench も計測。結果から。1.02倍。
UnixBench
130W → 6552.1
65W → 6422.2

うーん、微妙な結果でしたね。実際に、ゲームのベンチマークソフトで計測しないとわからないので、また追加でテストしてみたいです。
