The G92 Architecture Rumours & Speculation Thread

Well, the article compares it to two RV670 chips, so I assume they mean 3TFlops in SLI. 1.5 per chip isn't too far out there if the shader clock is >= ~2.1 Ghz.
 
We don't know the performance of a part launching in 3 weeks yet we speculate on rumours heard from a "friend" about a part that could very well land a year from now. Nice...

:)
 
3Tflops?

I fail to see how that's possible, even on 45nm, and wonder where they'd have the bandwidth to feed something like that, when the fastest thing conceivable right now would be about twice that of G80, 512x2800/8...or perhaps 512x3200/8.

A GX2-type part, maybe, but even one GPU@1.5Tflops would require something like twice the shaders (256x2+1 or 256x3) @ ~2ghz shader domains. While possible, especially on 45nm, and perhaps even 55nm/65nm, pushing a GX2 part of that so quick would seem nutty. Perhaps they mean SLI?

EDIT: 9/11 beat me to it while I was refreshing my coffee cup mid-post. :)

Not just your everyday SLi, but i bet they are talking about the three way SLi.

This would mean 1TFlops per chip, and this backs up the claim of the 1TFlop rumour from B3D regarding G92.

The plot thickens yet again.. :LOL:

note - are they referring the 3TFlops number with the geforce 9 series or G92??
 
GeForce 8800 GT Has 112 SPs Clocked @ 1.5GHz

Several sources are suggesting that the upcoming GeForce 8800 GT has 112 stream processors like the new GeForce 8800 GTS 640MB SKU. We also heard that its shader clock is running at 1.5GHz. CJ did some nice analysis on the Nvidia's strategy here on why is there a new 8800 GTS SKU. He revealed that there is a shortage of GTX cores but plenty of GTS cores going around that didn't quite make it as a GTX. So if you launch a new product that is faster than a 8800GTS, no one will buy the more expensive GTS unless you up its stream processor count for higher performance. Also with a 320-bit memory interface, it certainly perform better at high resolutions and with lots of AA/AF/HDR. This way Nvidia can still get rid of the inventory.

About 3 Way SLI... their implementation is kinda interesting and I doubt that it will really lift off... You need a special SLI bridge which kinda looks like this:

Code: 
A xxxxxxxx B           C
                 x
           x
     x
A          B xxxxxxxx  C
Card A connects to B (from left to right),
Card B connects to C (from left to right)
Card C connects to A (top right to bottom left across B)

I don't think it'll become a big success because it's a very expensive connector. ATi's solution is supposedly cheaper.

Only 680i and MCP72XE (780a SLI) mainboards will support 3 Way SLI and for now only G80 supports it since it has 2 SLI connectors on each card. G92 won't support it initially because the PCB only has 1 connector. The interesting part is that MCP72XE sports an onboard graphicscard (first for a discrete chipset!) and supports Hybrid SLI. This Hybrid SLI isn't so much for extra performance, but for a lower power consumption. When your discrete graphicscard(s) isn't doing anything, the drivers will turn it off and the onboard GPU will take over.

What's not expensive in SLI, especially in the tri-card variant ? ;)
Only works with the most expensive graphics cards of the line-up, only works with top motherboards and likely top power supplies, RAM modules, etc.

Now the IGP in MCP72XE looks interesting. May preclude a real boom in mobile Nvidia chipset usage in the near future.

I'm sorry if this has been answered already (it's a long thread), but why no Direct3D 10.1 support?
