The Official GTX480 & GTX 470 Thread

[rjbarker]

If EVER Nvidia come with a dual GPU with Fermi, which I seriously doubt they will considering the astronomical engineering obstacles they already face with 1 GPU, it will be even more castrated, probably around 418SP, and even lower clocked than the 470, probably around 550Mhz, in order to stay withing the 300W PCIe power cap, which they already blow with the 480 anyway!! The result could be something between a 480 and a 470 SLI, or about the same as a....5970!!! LOL forget it, it won't happen

An aweful lot of speculation....their has been a dual GPU Card since when...78xx Series....you honestly think that thier won't be...I would bet dollars to doughnuts in th next 6months we'll see not only a 512 core 480, but also a 470x2 Card.

Actually here is what I'd like to see:
5870 owners run an hour long loop of Vantage with your Fan set at Auto and post up your Temp results via Screenshot.........would be interesting to see those results.

i believe the first was a dual 6600gt by gigabyte..wich gave nv ideas later on :)

There is no PCI-E power cap.

[_dangtx_]

the new pci-e buses give out 150w or something right?

I'm sure he was referring to the maximum amount of power supplied by PCI-E connectors. IIRC, the board slot can supply a max of 75w, each 6 pin is 75w, and each 8 pin is 100w.

[burebista]

75W through PCI-E slot, 75W through PCI-E x6 cable and 150W throught PCI-E x8 cable.

burebista beat me to it. I was coming back to edit my post.

Here's a good page for the power connections specs BTW: All about the various PC power supply cables and connectors

I know what he was referring to. However, there's no limit as far as the PCI-E spec is concerned. A PCI-E slot can supply 150W (PCI-E 1.x is 75W, so most cards limit themselves to drawing 75W from the slot), 6-pin connectors are 75W, and 8-pin connectors are 150W. However, there aren't any limitations regarding what the connector arrangement is on the card. nVidia could easily stick two or even three full 8-pin connectors on a card, which would be plenty for even a dual GTX480 card (heat would be another issue, but I'm not talking about that right now).

Is this place legitimate? If not, we could PM with NCIX assuming this isn't below cost...Unfortunately, my abysmal French fails me at their telephone menu.

Wow. Those are some good prices.
