Yeah that score seems about right.

The fastest clamshell was the Key Lime one @ 466MHz over a 66MHz FSB.

The chiclet was launched @ 500MHz on the same 66MHz FSB.

Minus a point or two hear and there, they should bench roughly the same.

I do think the snow ibooks saw updated video. Yes it was a Rage and 8MB of RAM. How much does the Clamshell have?
