nVidia G80 Specs Leaked

[rodney_ws]

I agree that folding will boost energy consumption, but I imagine that a lot of people here already leave their computers on... so it's really a matter of how much extra energy is consumed when having a 300+ million transistor GPU crunching away at some mathematical problem. A GPU under load consumes considerably more power than one at idle.

I'm @ home downloading the client now...I'll tell you how it is with my X1900.

8 TCPs & 128 stream processors
Does anyone have idea what are these?

i'd just like to say nvidia is crazy with their pricing. beofre they had unified pipes, i thought ati was gonna obliterate nvidia but now it's a battle i have to see. anyway, watch ati's flagship dx10 card be priced at 499USD or something sweet like that to punch nvidia in the gut. 100$ difference between ati/nvidia cards at equal performance levels? (not going past 1280 resolution) pfft.

oh man !! i can`t wait to buy a 8800GTX 😀
long live the nVidia :tongue:

i'm sure the 8800GTX will demand that premium when it is the only DX10 card on the market, when ATis card comes out either the GTX will be lower priced or ATi will price their card similiarly, ATis introduction price points have not been lower than nV in the past, don't expect them to be lower now

I think the price is pretty fair, considering it is dual core.

Seriously, everyone who's asking how it is possible to get that many times the shader performance, look at the transistor count. Its 700 million, it is a dual GPU setup. There is currently no way you could do that on a single die and expect reasonable yields.

Go read the wikipedia entry on stream processing if you're curious. It seems to be some sort of parallelism method they're probably using between the GPUs. It is probably a lot like Raven said, 256 bit memory to the main, 128 to the secondary and you get 384.

 

[Ycon]

Whats the deal with that 256-bit + xxx-bit memory interface?

I started to explain that in my post page back....

The other guy has mentioned about phyics, that might explain the odd amount of ramage on this card. I don't know if there's a possibility that this card can render graphics and physics.

its a possibility nvidia decided to integrate the second memory of 128mb with the lower bus width for physics for the second core, the first core with 512mb of ram at 256bit would be the standard gpu we've been used too,

this is just speculation but with nv and ati's attitude toward developing there own physics cards this could surely be an option that nvidia is going with

 

[chuckshissle]

That would be nice if finally we would be able to have good visuals and physics. 😀

 

[Santino]

wow some of the specs looking kinda weird, 256bit-128bit hybrid memory bus, 512-258 hybrid memory, whats that all about, it will be interesting to see how this would affect performance of the graphics card

 

[raven_87]

From my knowledge, the only thing thats prevent true physics calculation in current Nv architecture is memory caching and buffering. I doubt the extra buffer and ram is an onboard physics processor though....

It's not a possibility anymore. It's the only sane logic reason how such memory bus configuration can exist on a single chip packaging through two cores.

All explained here which kaotao pointed out and you participated in and got this idea from.

exactly, with these almost identical topics i was relaying the info from the other section that i thought was worth while

 

[chuckshissle]

If that's the case I can't wait to see some reviews and especially with the upcoming game Crysis which I'm hoping it will supports physics processing unit.

Thanx, I try to do my part.

Sorry didnt realise it was already posted..
