G70 has 'many' clocks - Nvidia
 

Nvidia's Chief Scientist, David Kirk has suggested that "People just don't know as much as they think they do" when it comes down to the "Many" clocks within the GeForce 7800, aka G70.

"It's somewhat hard for us to say 'the core clock in G70 is this single number'", says Kirk. "We didn't want to be accused of exaggerating the clock speed, so we picked a conservative number to talk about the core clock speed. But, yes, that is just one of the multiple clocks."

back in November 2004 Anandtech already reported on the flucuating clocks speeds

it's called clock gating and is borrowed from their laptop 6800 tech:)

i think it's an excellent thing they have implemented, who would be against it? it was kinda lame in the comments that the ati fanboys came back up with the 3dmark cheat which is over 2 years old, specially if you know that ati has cheated too before nvidia did it
