NVIDIA Fermi: Architecture discussion

Another small clip of the sled demo. Around 0:55 there's a collapsing bridge that the legit guys didn't get in their video.

I'm getting really tired/bored of all the it's fast/slow, hot/not nonsense. Time to cut the BS and see what the real deal is with this thing.

 

The pdf says: "<225W".

I remember numbers below 200W being given by NV (190W afaik).

 

Not to add to the paranoia.. but ehm.. why.. after last night's (for me) talk .. does nvidia suddenly cover the PEG connectors with a sticker?

 

190W is the "typical" power draw, kind of like AMD's ACP on Opterons. As for the max power being <225W or 225W... it's supposed to be a limit anyway.

 

They're not stickers, they're a reflection in the case window of a lighted NVIDIA logo behind the camera.

(I presume you knew this, and are just being silly. Not that this thread needs any more silly).

 

IIRC it was <=225, not <225?

 

This could be an explanation for the strange supply cables issue...

Currently there are no >300W DX11 cards on the market...
Could it be an hint of Fermi sporting two 8-pin connectors?

 

New 28nm wafer from GF on the spot

Some real silicon ASIC, says Charlie - not an SRAM test vehicle.

 

what ? it's late did I just read that right.. TWO 8P connectors :

since when are there any >300W DX11 graphics cards to begin with. Even the gluttonous 5970 is under 300 at stock (and shoots frighteningly upwards when OCed) and thats 75W less than what dual 8Ps would offer. Wouldn't PCI-SIG have to sign off on the addition of a 2nd 8P PCIe power connector ? I just don't see any card using dual 8P connectors and (imo) it's a "More is Better" approach by Enermax to sell more (expensive/power hungry) PSUs.

 

It's the same thing, "<=" or "<" mean 225watt maximum power draw.

Surprising no one is suspicious with their "max board power" though, as they actually have some boards above their official max board power.

Try GTS250 (150watt, but measured 25 to 50 watt over HD5850), GTX285 (204watt, but 20 watt higher than HD5870 188watt) and GTX295 (289watt, but 25 watt higher than HD5970 294watt).

Little video of NV Surround Gaming. Today there should be more material about that.

 

Yeah that bridge looked cool too, even though the quality of the video was kinda poor. The previous demo runner always crashed (the sled) so he never got that far.

 

Since when there are cards with two 8 pin connectors, like the MSI HD5870 Lightning.



If an humble HD5870 can draw more than 300W in extreme OC, then also Fermi could, even at stock.

 

Ah, no? You see clearly that GF100 has only one 8-pin connector. But you have a 5870 card from msi which supports two 8-pin connectors.
I hope that nvidia and amd will not go over 300 watt with their cards.

Can somebody writes what andre fear is saying about fermi and Surround Gaming in the first part of the interview?

 

It has only 1x 8 pin connector, but with way more cables than necessary in it. Could it be a way to disguise the need for power of the card?
Anyway, I hope that no one goes over that limit, too.

 

You can put two 6pin connectors to one 8pin. Then you have a lot of cables, too.
Look at the other pictures of GF100: Both have a normal 8pin cable.

 

Has MSI released the clocks of this card? There seems to be quite a bit of potential, but I still haven't heard anything. I also wonder if they're using 5GT/s GDDR5, in which case there probably won't be much of a difference in bandwidth, or if they went for 6GT/s memory.

 

1Ghz core. It's an overclockers card so the twin 8-pin connectors are there for that reason. It doesn't mean it uses over 300 Watt.

 

This is a pretty good video of the demo:

Thanks goes to Zogrim.

There indeed will be "SLI -certified" cases now, too
