所感

ダメ。

ラズパイ3で熱暴走の問題があったけど、3B+ではCPU温度70℃超えると、サーマルスロットリングが発生して600MHz~1.2GHzまでクロックダウンする。

config.txtで定格1.4GHzにしたら何度もハングアップした。

そもそも3からクロックアップしてあんなちっこいゴミみたいなヒートスプレッダでどうにかなるという考え方がどうかしてる。

そして、よくケースとかに付属してるヒートシンク、あれ1個ではサーマルスロットリングを回避できなかった。

今回、定格1.4Gz保ったままUnixBench完走出来たのは、別途ヒートシンクを何個か重ねて追加してサーマルスロットリングを回避出来たからであって、標準の状態では、よっぽど寒い場所でない限り、定格1.4GHz稼働は絶対に無理。

3B+の1.4GHzという表記は、IntelでいうところのTurboBoost時のクロック数の表記に近いものだと思ったほうが良い。

よって、個人的な所感としては、3B+は無印3をマシにした程度である、と思う。

となると無印3はゴミですね、今更買う価値無しです。

今回はちょっとガッカリだったので辛口となりました。

おわり。
