Safari 6.0(dev) vs Chrome

WWDC2012で一番気になったのがSafari6.0の発表だったり。*1
地球上で最速のJavaScriptエンジン(?)と公称していたのでSunSpiderで試してみた。
実行しただけなのでなんの工夫もないですが、メモがてら…。

マシン

* Mac OS X バージョン10.7.4
* Intel Core i7 1.8GHz, Memory 4GB

環境

* Safari バージョン 6.0 (7536.16)
* Chrome バージョン 19.0.1084.56

下に結果、そのまんま貼りました。
Safariの方が1.3倍高速と出てますね。
もっとも、ブラウザは使い勝手とかあるので、この結果が全てではないと思いますが…。
