Speaking of which...guess who said this in the past, relative to R-300's power supply:

"How is that a "wild" assumption? It was a card in a lab with no heatsink assembly on them that I noticed. Of course, it could have been a final reference board, but it is hardly "wild" to even think they are boards designed for testing."
My, aren't we sensitive today. It was a guess pulled right out of air, thus making it wild. There are no jumper wires visible on those boards, they look rather finished to me (if extremely HUGE compared to the R9700s rather sleek design, especially considering the NV30 isn't going to use a 256-bit memory interface).
"In any case, the way I take the wording is that he was not even assuming they used a different card for "test cards" than the final board design, just that those cards were being used for testing, and being in a lab and all I'm not sure what other conclusion you could draw."
I think you're reading things into his words that weren't there to begin with. Note he says "test cards" as OPPOSED TO "final boards". Pretty clear-cut to me...

my assumption was that they were final silicon being texted in the lab. From my memoery of the shots of rampage in the 3dfx labs being tested that came out, all kinds of extra connectors, separate power supplies/connections were used on the test bed motherboard & cards.
Therefore I was proposing this might be the case here, that even if it is a molex connector (which I beleive it is) - it doesnt mean it will be on production boards.

Please explain to me why clock speed has anything to do with this?
Its about power consumption.
And while clock speed influences power consumption, its not the be all end all predictor of it. Things like processor die size matter...
Also, i suggest you read up on the power supply capabilities of AGP 3.0

Why? These chips are going to be using the .13 micron die process, which means that they'll almost certainly have less power draw than the R300. They could just be on those boards for testing purposes.
And don't forget that besides PR, nVidia has a direct incentive not to require such things: their sole customers are board vendors. You can be certain that board vendors are going to put as little on the boards as possible (And don't forget that putting a power connector on the board requires more than just the connector itself...that power needs to be converted to a form that the chip can use, meaning lots of capacitors, resistors, transistors, and whatnot).

You will need them with or without the power connector, the difference is just that the source is from the AGP bus or the connector.
If you have any doubt, simply check out pictures of a GF4 Ti4600 (or a physical Ti4600 card), my ELSA 925VIVO have regulators, capacitors, resistors, chips and inductors near the end for regulation and conditioning.

Chalnoth said:
So, given your arguments against NV30 having an external power connector...how would you explain the power connector AND the cooling supply then?
I really would like your answer on this....
maskrider said:
Correct, but the power supplied by the power connector and the AGP bus are different.
And while the engineers might be able to share some of the same circuitry between the two power supplies, you can be certain that the additional power connecter will need a good deal more circuitry (Unless, of course, the graphics card attempts to take all of its power through the power connector, but that's not been the case to date).

Obviously there's going to be a card released with this stuff on it. However, weren't there two versions of the GeForce FX announced? I would venture to guess that only one will feature the exotic cooling and power connector.
Regardless, there is another silicon spin to go and a little while before final production begins. As we've seen in the past, shit happens. Remember the GeForce3 launch? How that card was supposed to cost $500? The yields changed so much within a month that that price dropped to about $300. I'm not saying that I think this sort of thing is likely here, I'm just saying that it's still not definite, and I doubt that all GeForce FX's available at launch will include the exotic solutions.
And one last thing. I wasn't really expecting 500MHz clock. I was expecting 400MHz.
Update:
Well, I guess I'm not certain about the two versions announced anymore. Maybe I was just imagining things. Regardless, I would be very surprised if every GeForce FX sold sported the exotic cooling (the power connector is more likely to be there...as I'm sure it's more expensive for most board vendors to redesign the board than to just put the power connector on).

The AGP 4x and higher slot still delivers both 3.3V and 1.5V. The 3.3V is intended for gpu/ram main power supply, and the 1.5V is intended for I/O, as is clear from the AGP specification. Older versions of the AGP slot could supply either 1.5V or 3.3V for I/O, as selected by the graphics card; Voodoo5 5500 was the last card to require 3.3V I/O support. In addition, there is one 5V and one 12V pin in the standard AGP slot, each capable of delivering 1 Ampere of current.

Exactly. Shit happens. Just because it would "cost more" for a particular implementation (such as a monster cooler and power supply connection), and it wouldn't be ideal for such a configuration...doesn't mean it won't happen.
Just because something is running on 0.13, doesn't mean it has less power requirements than something similar on 0.15.
Which is why I always cringe when I hear you utter the words "almost definitely", "for certain", etc.
