Radeon8500 vs Radeon8500LE
ATi製チップを使ったカードはクロックが違うバージョンが複数あり、かなりややこしい。Radeon8500もその例に漏れず、
いろいろなクロックのものがある。ここでは、純正品(core/memory:275/275)と一般に8500LEと言われているもの
(core/memory:250/250)を比較してみようと思う。今現在(2002/1)での純正8500と8500LEの価格差は10000円強(だと
思う^^;)だが、価格差ほどの性能差はあるか調べてみることにした。

(3) Quake3 Arena ver1.30 DEMO
左側の結果がRadeon8500、右側の結果がRadeon8500LEである。
| 1024*768 16bit | 143.1 fps | 137.7 fps |
| 1024*768 32bit | 138.4 fps | 131.9 fps |
| 1280*1024 16bit | 135.9 fps | 129.6 fps |
| 1280*1024 32bit | 115.5 fps | 105.9 fps |

| 2048*1536 16bit | 59.2 fps | 53.1 fps |
| 2048*1536 32bit | 33.7 fps | 29.8 fps |
1600x1200x32bitから差が目立ってきていることが分かる。1024x768では体感的に差は感じられなかった。
(4) Aquanox オープニングデモ
グラフィック設定は最高にして計測(垂直同期はoff)
・Radeon8500
1024x768 32bit Average 71.2 fps
1024x768 32bit Average 36.4 fps
・Radeon8500LE
1024x768 32bit Average 65.4 fps
1024x768 32bit Average 33.0 fps
この項目ではクロック差に応じたフレーム数の差が出ている。
＊まとめ＊
他にもいろいろゲームをプレイしてみたが、1024x768より低い解像度ではフレームレートの差は体感できるほど開かないと思う。ただ、1600x1200ぐらいになると多少問題になるかな、という程度の差なので普段1024x768あたりの解像度でゲームをしている人にとっては、8500LEはC/Pの高いビデオカードになるだろうと思われる。
