G71 specs according to Vr-Zone

[Ronin]

There are several sites (including AT) that say the memory jump from 256 to 512 doesn't make a tremendous difference (if any). Using that as a reference point for comparison isn't as valid as using other specifications (such as shaders, pipes, clock speeds, etc).

It was meant to beat the X1800XT, which it does...

They had to know about the X1900XT. R580 was on the roadmap for ages, and ATi isn't very good at keeping "secrets".

I have a feeling that will change when the new Unreal-based game is released.

Which is where G71 (7900) comes in.

That isn't the point. They also knew about G71, which sounds like it will beat the X1900's. It looks like their current strategy is to give ATI the lead for about 2 months this year, while they hold the crown until the next gen cards.

i agree with sickbeast

the 7800gtx was meant to compete with the x1800 series
and now G71 competes with x1900 series

ati was just late to the party with the x1800

Looks like they're hoping to scare away those who like to buy the second best (7800GT, 6800GT, etc.).

The 7900GTX looks killer, but as was mentioned, the 7900GT seems kinda weak, unless they price it really well i gues...

 

[5150Joker]

I wonder if ATi will respond with something faster - maybe a PE edition or something ala 512 GTX just to retain the PR crown.

Which makes sense. Sorry, I thought you were saying that the 7900 cards won't beat out the X1900 cards. I think you mis-read my post. When I said "that card", I was referring to the 512mb GTX debacle.

I wouldn't doubt an 80nm die shrink on the X1900 core.

That said, it's only a matter of time before the graphics companies "hit the wall" the same way intel/amd did. Based on current architectures, I would guess that ATI will hit the wall first.

you made an omission.

Looks like NV will have the performance lead til the R600, unless we see a X1900 refresh with die shrink etc.

I think G80 will re-establish NVs reputation in both IQ/feature/performance.

 

[moonboy403]

i'm sure ati will release a phantom card such as the pe edition

both companies have been doing that just for the pr crown (with limited quantity)

and it really sucks for us consumers

Hmm I dunno Intel/AMD are still continuing with die shrinks so I doubt ATi/nV will hit the wall until at least 2-3 generations and be forced to go dual GPU for high end performance.

Feature wise it might with HDR+AA. As for IQ, if they add in angle independent AF but it takes a large hit, that will be useless as well. Lastly, they need to work on improving their Quality AF (default mode) so that it is on par with ATi. Right now that's far from reality.

It's possible, but honestly it would be disappointing to me. G71 will only really be interesting if the 7900GTX is just a complete monster of a card. Personally, I think that a new core that supports WGF would be more exciting. If ATI shrinks X1900 then it will be a re-re-fresh of R520, much like the 7900's are going to be a re-refresh of the 7800's.

Now if NV makes the dual chip (quad SLI) cards available with G71, that might be a different story. I imagine that these dual chip cards are extremely diffcult to keep cool, that might exlain the "slow" clockspeeds of the GT.... hmmm...

It sounds like a yield issue, or else they will re-brand the old GTX cores as 7900GT's. The latter case is more likely.

 

[Cookie Monster]

I said that, because the G80 is NVs new architecture. It is there NV50. It has been in the works for a LONG time. It will probably be different to the G70 architecture like what the R520 was to the R420.

G71 is probably the last of its kind. (nv30 --> nv40 -->nv47/g70 --> g71)

 

[CP5670]

It's interesting that the memory speed on the 7900 GTX is actually a little lower than the 512 despite having the same kind of memory. I guess Nvidia learned from the fact that everyone is buying the 7800 GTs over GTXs these days and made the GTX a lot faster than the GT with the 7900 line.

The March 9 launch sucks though; it's three days after my step up period ends. I need to make sure I sell at least one of my existing cards quickly before it drops a lot in value, so I can upgrade to one of these GTX cards.

 

[akugami]

Judging from those unconfirmed numbers, the 7900GTX will indeed beat the X1900XT. The question then becomes, by how much? A 7800GTX 512MB at 550mhz is only slightly behind in most benchmarks to the X1900XT. Not enough to matter if you have either card. A 7900GTX at 650mhz should easily surpass the X1900XT. I think the jump to 32 shader units will help nVidia out in games such as FEAR where it wasn't doing as well as before but it won't help out much in most current games.

http://www.firingsquad.com/hardware/xfx..._7800_gtx_512mb_xxx_review/default.asp <----- Stock out of box overclocked.
http://www.hardwareoc.at/Gainward_Ultra3550PCX_GeForce7800GTX_512MB-4.htm <------- Not in english, shows overclocked benchies though.

The last link fron those 3 above is interesting because they show an overclocked 7800GTX 512MB at 640 core and 1770 memory. Assuming the quoted 650mhz core 1.7ghz memory is correct for the 7900GTX, that overclocked 7800GTX 512MB should be very close to what the 7900GTX is. The few games they showed did show a solid improvement in the games but nothing spectacularly so over a stock 7800GTX 512MB. In fact, I think that the performance jump will be quite similar to what that overclocked card showed. If anyone has better benchmarks of an overclocked 7800GTX 512MB, I'd be interested to see them.

Obviously we won't know fully how the 7900GTX will do and all we have is speculation. But if those overclocked 7800GTX 512MB's are an indication (and this being a refresh product it should be a decent indicator), the 7900GTX will be very good performors and should beat the X1900's. Just not sure it'll beat it by a large enough margin for owners of teh X1900's and 7800GTX 512MB's to upgrade.

 

[CP5670]

I am planning to upgrade just because I want a single card that's faster than my existing cards, as I'm not quite satisfied with SLI for my purposes. This GTX looks like it will be such a card.

 

[RobertR1]

I think VR zone is bit optimistic over the number of pipelines. I still expect 24. The 7800GTX 512 is plenty close to the x1900xtx is most benchmarks and the extra 100 on the core speed should help it eclipse that.

The performance difference is way too big between the 7900GTX and 7900GT if you were to believe that info about pipelines. Hopefully, I'm wrong and this card is the monster that it's suppose to be. If that's the case, I'll definitely have to consider getting it.

 

[Stoneburner]

IF (big If) the specs are true I dont see how the g71 wont be dusting the x1900. We are already familiar with the architecture and can extrapolate performance easily. I'd suspect just a 650mhz core would be enough to make it competitive with x1900.

We have got to know the specs for the upcoming 90nm G71 series already. There will be two models as we have revealed before; the GeForce 7900 GTX and GeForce 7900 GT. However, the performance differences between the two models seem to be pretty huge and we can expect quite a huge price difference too. We have yet to confirm on the number of pipelines on the 7900 GTX and GT but current sources point towards 32 and 24 pipelines respectively.

GeForce 7900 GTX will be clocked at 650MHz core / 1.6GHz memory and has 512MB GDDR3 1.1ns memories onboard while GeForce 7900 GT will be clocked at 450MHz core / 1.32GHz memory with 256MB GDDR3 1.4ns memories. We have also heard that GeForce 7900 GTX will win Radeon X1900 XTX in most benchmarks so we shall eagerly wait for the launch on March 9th at CeBIT.

So, it stands as

7900GTX
650mhz core clock
1600mhz Memory clock
256bit GDDR3
512mb

32pipelines
10VS (Assuming the architecture has 8 quads)
24?ROps

MSRP of $699?

7900GT
450mhz core clock
1320mhz memory clock
256bit GDDR3
256/512 mb variants

24 pipelines
8VS
16ROPs

MSRP of 499? This card might replace both the 7800GTX and GT. Since its 90nm, it looks like it will be OCable up to 500~ or more. The Gap seems to be huge though.

7900 gt could use 32 pipe otherwise it won't be much dif than the 7800 gtx
