NV40, NV41 and NV42 mentioned in Det 44.65

Been digging around the drivers.... :p :D

Uttar, NV33 is mentioned also, as you can see from the picture. It isn't a typo, thats for sure now. ;)

Hmmm very interesting, it seem Nvidia already has NV40 prototype made by IBM and probably already received first NV40 revision sample chips from IBM. :D

I knew it wasn't a typo as soon as a few hours after I posted it.
What it is, though, isn't much more exciting than a typo... Wasn't able to correct it though, otherwise it would have been too obvious it existed ( and I wasn't supposed to say that :) )

Good to get a confirmation of the NV40/NV41/NV42, though. Most likely emulations though.

Don't think it's emulation, I think it's more likely to be associated with different code optimisations in the driver. Like Aniso approach etc. It's a problem with a UDA that you have to support different architectures with the same code base when much of the code may not be shared.

Yeah, I know that - what I meant is that this is the driver nVidia is probably using on their emulation machines :) Because in order to see if the silicon will work, it's an awful lot easier to emulate it first.

Yeah i agree,

i bet by now they had enough time to setup one of those "IKOR" i think thats right boxes?

that can be switched to act like any chip you program, accpet at horrrrribly low speeds?

nvidia had a video on their website a while back that showed off their server farm. :eek: It was sweet.

could they use older cards on ln2 or very highly overclocked otherwise to give a close estimation or perhaps alpha silcon of the new cards underclocked and estimate how much itll scale?
