Looking at Ryan Smiths latest article concerning Nvidias GTC and its GPUs, i came over this bit:
So i asked myself, is the power"wall/roof" lower (more restrictive) for professional uses of Fermi? Isnt it the same 300watt roof?
GTX480 has 480 cores active right? The highest Tesla has 448 cores active to not cross that bar?
GTX470 has 448 cores active. Hows the power effiency of this Fermi part?
Comparishon between the 470 and 480 when it comes to power at load and idle:

The difference seems to be 70 watts more used on a 480 on a full system load.
So to users/owners of GTX480 and 470 too if possible, whats your single card power efficiency/usage like? I guess you cant give the numbers for the GPU alone but any number would be interesting.
Theory: Nvidia purposely crossed the PCie spesifications to provide "enough" of a performance lead for the GTX480 over the competing product HD5870?
GTX470 is now considered onpar with the HD5870, winning some, losing some, never by much and it wouldnt cut it as Nvidias highest performing card.
THere are Quadros with 512 cores active? Anyone got power usage numbers for those?
With GF100 NVIDIA basically hit the wall for power consumption (and this is part of the reason current Tesla parts are running 448 out of 512 CUDA cores),
