G71

[Ailuros]

The R580 won't be coming until early 2006 and my gut tells me that the 90nm version of the G70 will be around the same timeframe, ie. December/January.

December/January still belongs to the winter season, doesn't it?

If the R520 manages to make it to the market in any significant quantities and outperforms the GTX nvidia will release a dual slot Ultra at around 500+ MHz and a little faster on the ram (or slightly slower if they decide to go the 512 MB route). Mark my words.

I don't think so for any of the above.

I doubt this is all due guesses, rather orchestrated misguidance. What's worst is that it actually works....

Which presumes a conductor. Cui bono? NV? That would presume they are worried enuf about R520 to be starting up market-freezing FUD while their own part is Graphicus Rex, and hence gets hurt too.

Two Sapphire & tonics and I'm into Latin. One more and I may start on the Greek.

 

[Ailuros]

Ah, didn't the Inq already say the R520 is a 32 pipe card? Why make special note that R580 is the 32 piped card?

Neither/nor have actually 8 quads.

Start with german; ideally with Schadenfreude which the INQ used recently. A feeling I might preserve for the site itself in the foresseable future

Always been a weltanschauung guy, meself.

That would be congruent with information I've seen - G71 being an NV43 replacement, with a quoted "2x" performance increase.

Hmmm. 12 pipes @ 400-500MHz? Sounds like they'll have to move it to 256-bit to make that work. I'm encouraged by $150 X800s, though, that it's a workable config at $200-250.

 

[Fodder]

2 x NV43 (8 pipelines, 128-bit memory @ 500/500) sounds like 16 pipes, 256-bit memory @ 500/500, or rather like the long-awaited PCIE-native NV40 die-shrink.

 

[Arun]

I'd much rather guess on 12 Pipelines and 550Mhz, personally, with so-called "efficiency improvements" handling the rest (and they'd compare it to SLI anyway, which is not exactly doubling the performance).

I would guess the 256-bit bus depends on what they can do RAM-wise for it then. Perhaps 400Mhz 256-bit for the GT and 500Mhz 128-bit for the standard? Still, that sounds like it'd reduce their margins to me.

Perhaps, but G72 is also supposedly a 12 pipeline part (though on 110nm), and it would be odd to replace it so quickly, unless it's a similar case to NV41 and NV42.

The guy who posted the pics thinks it's the 7800 Ultra. But if it has something to do with G71 only god knows.

The cooler should be pretty effective. Nice to see a big (92mm?) fan too, should be quiet enough.

 

[CJ]

Ok, let's see what the Inq said about G71:

On prototype boards, cooling solution is separated in two halves, with nicely sized 72 or 80mm fan in the middle. Both halves feature large number of aluminium fins, through which two heat pipes lead the heat from the center block (hidden under the fan) which covers the GPU completely. Also, background of the board is identical to the one found on 7800GTX (plastic "heatspreaders" on GDDR-3 memory, plastic stabilizator on to release strain on the PCB).

So, to sum what we know about G71, possibly dubbed the 7800 Ultra:
- 110nm process, modestly revised GPU
- unexpected clockspeed (up till' this story, of course)
- dual-slot aluminium cooling with at least four heatpipes
- ultra-silent, large-fin large-diameter fan

In their "G71 is also dual slot" topic.

So far they've been spot on.... 4 heatpipes, large-fin, etc... now let's see that "unexpected clockspeed"...

Nice design, that ^^

 

[ChrisRay]

That cooler cant be cheap to produce. Of course I dont figure the 7800GTX cooler is all that cheap either.

 

[Jawed]

It's a shame that it doesn't vent all the hot air out through the rear of the case.

I guess that kind of design would increase noise significantly. I can well believe NVidia is going for a "silent" design here.

I was thinking the same thing. It looks like a Thermalright XP-120 and that thing ain't cheap. But man, is it effective? Yups!

 

[Xmas]

That certainly looks like an "Ultra"...

Who knows, maybe the dual-die rumours are true, and this is 2x G71, 2x 16 pipes and 2x 400MHz (=800MHz).

 

[neliz]

Why doesn't NV go for an "arctic cooling" kind of design? with offboard fan etc?

Now it looks like it's either pulling or pushing 50/50 from inside/outside the case..

Nah, that would prove "solid snake" over at nvnews right.

he pointed out back in may that the ultra would have 512 bits (2x256) and was a dua core/chip design...

I thought "dual GPU" when I saw that cooling design as well, but if you look at the pictures, especially the one showing the back of the card, you can see that there is only one GPU on there. The dual heat sinks are just there to dissipate the heat from the central area where the GPU is located, using heat pipes. So, I think it's just an example of extreme cooling for a single GPU solution. Might be exciting.

 

[neliz]

Might be exciting.

Might be necessary
