Really ? Then why bother with clock gating on a chip at all ?
Everybody does it now, from Intel to AMD to Nvidia. Your card won't be speeding away full throttle while surfing the web on AERO Glass. And you can't argue that some games are simply less taxing than others, sometimes on different parts of the same chip (texturing or shading, fill rate or memory bandwidth, etc), sometimes it even varies from scene to scene within the same game (different maps and levels of detail).

PCPer did a review of the Quadro CX 1.5GB (1.5GB GDDR3, 192 scalar processors, 384bit bus), and besides confirming the presence of the 55nm GT200b, they also showed what i believe is the first board carrying any GT2xx that only requires a single (!) 6pin power connector, which implies a TDP well under 150W.
Could this, coupled with the 384bit bus and 192 scalar processors onboard, mean the possible debut of a direct consumer replacement product for the 9800 GTX/GTX+, and perhaps even the 9800 GT ?
You misunderstand.
You don't need performance when there's no workload.
Get it now?
