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。
