15ドルPCの Orange Pi PC が来たので、動作確認をかねて、とりあえずベンチマークを計測。温度が80度近くになって心配でとりあえず、手元にあった放熱板を仮置き。
$ cat /sys/class/thermal/thermal_zone*/temp
結構、熱くなるようです。まぁ、それだけ速いということですかね。電源はPSP のがなぜかジャンク箱にあったのでそれで。
なかなか、速いんじゃないですかね。622.9 出ていますが。RasPI2が400くらいなので、それより速いことはわかりました。とりあえず、ログだけ乗せておきます。
重そうなmate desktop も実用に耐えうる速度。
VNC でつなげてみました。CPUパワーがあって、これが15ドルとは思えませんね。
OS は、とりあえずloborisさんの、OrangePI_Ubuntu_Vivid_Mate.img を使いました。デスクトップGUIで、ブラウザー起動しましたが、なかなか速いです。レンダリングはドライバーの問題か、少しもたつく感じ。環境を整えれば、何かの用途には使えそうですね。送料込み、2300円くらいの価値はあるかと。
