If THAT's true, HOLY SH**T
 
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...?
 
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.
 
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.

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.

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