Granted it's entirely possible that he doesn't know what he's talking about.

NDA will be lifted by Nov/16

My friend got gray varigated G80 board and he told me performance of G80 is above his expectation. ( 2 times 7950GX2 is plausible . )
Actually I'm bystander , a 3D Maniac and I oathed myself long time ago -" I cant get at 3D Field for my bread and butter ."

hmmm... yeah, sounds somewhat suspect... I don't frequent B3D, is this person reputable...?

 

[lopri]

Sort of. My expectation for G80 comes mostly from the economic ground and the very existence of 7950GX2. We now know the G80 will be a massive, power-hogging beast with $650 price tag (for the GTX). With such a profile, if all it can give us is a slightly better performance than overclocked 7950GX2, NV will have a hard time persuading consumers. I wouldn't be sure about double the performance of GX2, but 3 times the performance of single G71 wouldn't be too unreasonable.

 

[nitromullet]

I'm thinking it will be about 2x 7900GTX (not 7900GTX SLI, but actually twice the avg fps of a 7900GTX), which puts it a good notch above a GX2. Anything above that is gravy IMO. However, I think the real kickers will be:

-16xAA with a single card, which would be doable in a number of games with performance like that.
- HDR+AA ...all of a sudden games that didn't officially support it will through a patch (TWIMTBP at work)
- DX10 support, a checkbox feature at first, but an important checkbox and definitely a sales booster
- NV usually surprises us with a feature every gen as well. NV4x brought back SLI, G7x had transparent AA at launch, and later Quad-SLI, and no one suspected any of those prior...

Impossible, I've never heard of an NDA lifted more than a week after a release date. I wouldn't believe this guy even if you bet me a $1000.

Personally, I would hope this is true. Gotta justify the higher power demand IMO. Realistically though I prefer to see actual unbiased preofessional reviews first before believing something like that.

Yeah, I expect it to beat 7900GTX SLI. If it manages to eclipse a pair of 7950GX2, well, excuse me a moment...

everyone hopes this is true

but all we have is speculation on speculation on speculation . . . pretty soon we'll hear that it'll be 20 times faster than a GX2

. . . . and do we have *confirmed* that the flagship g80 is single core, right?

. . . G80's flagship is successor to the GTX, not the Gx2 . . . right?

. . . if that 700 million transistors if for a single core . . . then . . . yes . . . that is really impressive. . . . no matter how it compares with r600.
:Q

Think about it this way. G80 will have a successor - G85. nvidia likes to double performance between generations, which would mean g85 has to be faster than 4x 7950GX2. Question is can a die shrink and GDDR4 realise that sort of gain from G80?

That depends on if the G80 refresh is simply going to be a die shrink and new memory. We don't know exactly what a G80 refresh might entail, but I doubt that a G80 refresh will be twice as fast as a G80. Was the 7900GTX twice as fast as the 7800GTX? Nope. Was the 7900GT twice as fast as the 7800GT? Nope.

 

[thilanliyan]

I'd be impressed if it matches a 7900GTX SLI setup. I doubt it will match 2x7950GX2.

What about dual 8800GTXs?

i doubt G85 will double performance over G80

7800gtx -> 7900gtx didnt double performance
7900gtx -> 7950gx2 didnt double performance
6800ultra -> 6800ultra extreme didnt double performance
5800u -> 5900u didnt double performance
5900u -> 5950u didnt double performance

theres no reason to say the G80 -> G85 will

A 7900GTX SLI already matches 2x7950GX2 as well as the X19k CF counter parts. Quad-SLI just isn't worth it at the moment.

 

[Gstanfor]

6800U to 7800 GT did, 7800GT to 7900GT did. I still think it's a large ask. The performance may be capable of getting up around 2x 7950GX2, but I doubt it will be able to consistently sustain it. I'd like to be proven wrong though.

thats a different generation of cards. by your post it makes it sound like you're talking about a refresh within the same generation

7800GT to 7900GT did.

I was confused too... Not only is the 7900GT nowhere near 2x the speed of 7800GT, but neither of those are flagship cards.

 

[Gstanfor]

All those chips are nv4x deriviatives - remember G70/71 is really nv47/48.

The 7900GT was faster than 7800GT (or was it 7800GTX?) SLi'd - thats part of why it was such a huge success with consumers.

But that's not what you originally said. You originally implied that G71--the refresh for G70--was twice as fast as the original G70 when you said:

...nvidia likes to double performance between generations, which would mean g85 has to be faster than 4x 7950GX2.

I said that the 7800GTX to 7900GTX didn't meet the "twice as fast" standard. You then said that the:

7800GT to 7900GT did.

In fact, you said:

The 7900GT was faster than 7800GT (or was it 7800GTX?) SLi'd - thats part of why it was such a huge success with consumers.

when in reality 2 7800GT's or GTX's in SLI will beat a single 7900GT anyday.

Huh?

Are you trying to say the 7900GT was faster than the 7800GT x 2 in SLi, or that the 7900GT in SLI was faster than the 7800GT? If the latter, that's a no brainer, since the cost was twice as much, if not greater at that point, than a single 7800GT. If the former...

what? . . . speculation

we haven't even got an idea of G80's DX9 performance and you are already talking of doubling performance in the refresh
:thumbsdown:


and you can never be proven wrong . . .
--in your own mind

ANYway . .. do we know if the flagship G80 is a successor to the GTX or the GX2? Will those 700m transistors be 'single core'?
