Gigazine編集長の魂の叫び

【求人募集】GIGAZINEのために働いてくれる記者・編集を募集します

「長としてどうなの？」などと思う部分もあるけれど、
当人にしかわからない現実があるのでしょう。
私個人としては、ちっちゃい爆発は仕方ないけど、おっきな爆発はしたくないと思う。

体調が悪いので今日はここまで。

Intel モバイル向け省電力CPU スペックまとめ

Intel のモバイル向け省電力CPUのスペックです。

今回も情報はインテルのウェブサイトより転載。

簡単にまとめると
・i3はターボブースト非対応の為、性能には期待できない。
・i5 5XX以上になると、周波数以外の違いがほぼ無い様子。
・i7-620UEは特性が他と異なる。

Intel G1101 G6950 i3 i7 のスペック比較

先日購入したNEC製サーバ GT110b の CPU Celeron G1101 がどのようなスペックか気になったので、
G6950, i3, i7の主要製品と比較。

今回も情報はインテルのウェブサイトより転載。

廉価版とはいえ、最近のCPUなので VT-x、64bit には対応しています。
i7-970 はソケットが異なるので注意。

2010/07/23現在気になる Intel Mobile CPU i3, i5 の比較

IntelのノートPC向けプロセッサ（モバイルプロセッサ）の比較ができるように纏めてみました。
なお、情報はインテルのウェブサイトより転載し
独自に気になる点を強調しています。
■まずは、CPU毎の基本的な違い
i3 3XXM⇒ターボブーストが無い。グラフィックのクロックが劣る。
i5 4XXM⇒ターボブーストが控えめ。
i5 5XXM⇒ターボブーストが強い。
