    7700go = 7600go unlocked?

    pure speculation, but it seems to me that the 7700 is just a 7600 with a firmware upgrade to unlock the the extra pipelines.

    thats pretty interesting. Right now I have a Compal HEL80 but next spring I'm going to get another notebook. I might consider getting a laptop with a GO 7700 or the Go7700 GT. I can imagine the battery life.

    That X-Bit labs article is all messed up. I know nVidia is claiming they got the first 80nm chip with the Go 7700, but that's not true. ATI got there first with the RV535 which is the 80nm shrink of the RV530. The RV535 is used in the X1650Pro and X1300XT.

    This statement also doesn't make sense. First, they are implying that the Go 7700 was just a die shrink of the Go 7600, and because "there is no difference" between the two that the Go 7600 had 12 active pipelines too. That obviously isn't true. At the very least, the Go 7700 had 4 pipelines activated, although I think those 4 pipelines are completely new. There report on the clock speeds also don't make much sense since that means that the Go 7700 and the Go 7600 operates at the same frequencies. However, the Go 7700's performance advantage over the Go 7600 doesn't reflect it's 50% more pipelines since it only gains 100 points in 3DMark 06 for instance. That seems to mean that the Go 7700 is clocked lower than the Go 7600, not the same, which will also allow it to control power and heat. (The 80nm process is a cost node so it doesn't offer much benefits over the 80nm process in power consumption.)
