Why are Nvidia cards so power hungry but dont perform ?

Compared to an ATI card for instance ?

Is it the way a Nvidia card is made, why need a nuke reactor to run
it, Nvidia must have Clue to fix this ?

Thanks.

The same reason AMD chips run hotter then Intel chips.

They just havent kept up with lowering the micron production, and lower
voltages = lower heat = lower noise cooling fans needed.

Don't start flaming. I use both AMD, and Intel, as well as nVidia, and ATI.

But my fav (SILENT) fast machine , is a P4 2.8GHz and a 9800Pro .

Isn't it intersting that nVidia who bought out 3dfx , would come up with the
same "overpower at any cost" card in the 6800? Remember the Voodoo5? With 2,
or 4 processors, to compete with a GeForce2/3 .

Except now it's Intel chips that run hotter than AMD.

And now Nvidia has just shown the NV45 cards, with a single connector
(though with more pins), and bridgeless. Will it work in an SFF? Probably
not, but they seem to be trying.

Might want to flip that, current generation AMD chips run cooler than Intel.
That's part of the reason Intel has decided to go dual-core.

The way I understand it is this. NVIDIA uses more transistors, which
requires more juice to push through all the resistance, but all the extra
caps gives us more features. I don't see the power consumption as a big
problem, only for the people with older or low quality PSUs.

A slightly fact-less observation............

Presumably refering to the 6800 ?

Read the specs and reviews ?

You do know that the 6800 has significant VIDEO-processing functions
that have not yet been turned on by the current drivers, even "beta"
ones ? These functions also consume transistors and some power, even
when nominally "inactive" The power in the 6800 is solely-related to
transistor-count --- the process technology is 130nm, same as ATi
X800. Anyway, nVidia is being deliberately conservative in their
power-supply recommendations, and assuming that a PC with the 6800
will also have a top-end CPU (Prescott, anybody ?) and a bunch of fast
disks.

Wait 3-6 months until both the 6800 and X800 drivers are mature, then
publishing your performance-functionality/power observations at that
time may make a lot more sense.

Word is that the new ATI crop of cards ought to have the same video
processing functions.

Heat plays a big role in the noise level of a PC and power consumption has
to do with heat generation. Dumping excess heat into the case just means
that the fans have to work harder and louder.

Not flaming just liked to know now i do.

I Upgraded from a Geforce 3 Ti 200 and before TNT2


I just buy the best card for the money i can afford, which was a
Radeon 9600 Pro, might get a 9800 pro when the prices come down.

See ya.

Personally I think it's the GPU manufacturing process isn't as efficent as
ATI's. That's not saying Nvidia GPU's themselves are'nt as efficent as
ATI's. Also Nvidia in general has more power-hungry cooling solutions than
ATI.

Power consumption is proportional to transistor count, which depends the
number of features implemented in hardware. Full-precision FP32 throughout
the pipeline increases transistor count. Full SM3.0 support increases
transistor count. ATi chips don't support these, so the transistor count is
smaller. It's as simple as that.

Take a look at this article:
http://www.anandtech.com/showdoc.html?i=2068

There will be a dedicated single power lead for video cards in
next-generation power supplies, similar to the ATX12V lead for P4
motherboards. Both nVidia and ATi will be using the same connector.
