http://www.kitcc.org/~bugyo/b-log/?p=133 Continue reading RH3450-LE256H/HS取り付け]]> 放置していたRH3450を取り付け。
CPUの水枕も取り外し、Kama Angleに付け替え。
これで水冷ともおさらば。

で、ベンチマーク。
確かにGDIが遅くなっている。
ただ、GDIのアクセラレーションが効いてないからかどうかは不明。
そもそもGDIのアクセラレーションってどういうものか結局分からない。
BitBltがほぼ半減している。
これが原因ではないかと。
X700ProのメモリバスはGDDR3、432MHz*256bit*2、
HD3450の方はDDR2、800MHz*64bit*2、
でレイテンシが同じならほぼ半分。
BitBltのスコアもほぼ半分で合ってそうなと思ったのだけど、
メインメモリがDDR400なのでこっちの方が遅いような。
じゃあなんで差が付くんだろう。
こんなことなら、自分でベンチマーク用のコード書いておくんだった。
