とりあえずCPU性能を測ってみるよ!いつものUnixBench
ストレージはmicroSD(クラス4,8GB)、OSはUbuntu13.04(arm版),もしかしたらbeaglebone版みたいなものかも。

139ポイントだった。
ラズベリーパイ(ノーマルモード)は73
Raspberry Pi(ラズベリーパイ)を使ってみる -4.性能 unixbench- | Linuxブログ
ラズベリーパイ(ターボモード時,raspbianのみ使用可能)は156.7
Raspberry pi(ラズベリーパイ)を使ってみる – 新raspbian20120918版でターボモードを試してみた – | Linuxブログ
感覚的に、安定して早くなっている感じ。ラズベリーパイターボモードは常用すると寿命縮むかもだから、評価に入れるかどうかむずかしいところ。
ラズベリーパイよりCPUが速いとは聞いていましたが、本当に速いみたいです。
