パチスロ 並び 段ボール　前回はラズパイ一体型キーボード「Raspberry Pi 400」の外観をご紹介した他、「技術基準適合証明」（技適）を通っていないデバイスを試すときの手続きについて紹介しました。今回はベンチマークソフト「UnixBench」を使って実機のパフォーマンスを確認していきます。

　UnixBenchはLinuxでは定番となっているベンチマークテストで、整数処理演算や浮動小数点演算、ファイルのコピーなどを行ってシステム全体のパフォーマンスを計測します。最終的には「System Benchmarks Index Score」の値で総合スコアが表示されますが、これは「Sun SPARCstation 20 SM61」という、1995年頃のコンピュータの性能を10として比較したときの値です。

　UnixBenchのインストールは、GitHubにアップされているファイルをフォルダごとそのままダウンロードすればOKです。UnixBenchがインストールされたディレクトリに移動して「./Run」で実行します。

$ git clone https://github.com/kdlucas/byte-unixbench$ cd byte-unixbench/UnixBench$ ./Run

　今回はRaspberry Pi 400とRaspberry Pi 4の2GBモデル、4GBモデル、8GBモデルの4つでUnixBenchを使ったベンチマークテストを行いました。それぞれでシングルコア、マルチコアでのテストとなります。結果は以下の通りです。

UnixBenchでのテスト結果（クリックで拡大）

　Raspberry Pi 4よりもRaspberry Pi 400がかなりいい値を示しています。これは搭載されているSoCの違いです。

　Raspberry Pi 4はSoCが「Broadcom BCM2711（Quad core Cortex-A72 （ARM v8） 64-bit SoC @ 1.5GHz」だったのに対して、Raspberry Pi 400は駆動周波数が高い「Broadcom BCM2711C0（quad-core Cortex-A72 （ARM v8） 64-bit SoC @ 1.8GHz」を搭載しているためです。

　またUnixBenchはCPUの性能が高いほどいい結果となるので、これだけの差がついたのでしょう。たったの0.3GHzですが、随分と違うのだなあと思いました。

　ちなみにRaspberry Pi 4は搭載メモリの容量による性能の差はありません。

　今回のテスト結果について、以下に記しておきます。
