5870 is faster than a 295. the image quality is no comparison. you could say the same with gt200 v. rv770 too. sometimes being objective is nice:p

hmmm from what i remember reading through a bunch of reviews, a 5870 is about 90-95% of a 4870x2, hows that not anywhere close to it?Originally Posted by 003
i think the 5xxx series is overpriced, i want gt300 as badly as anybody, if anything to drop ati prices, and depending on price/perf to get a gt300 based card myself. i was spending as much time speculating in the 5xxx thread before the cards came out as i do in gt300 threads now...my post was @ saaya/ati fanatics who all of the sudden are interested in fermi or who think fermi will be a slouch or a no show until next summer
we should embrace both ati&nvidia and i hope they leap frog each other more often than once/twice a decade
hmmm are you sure from what i remember from all the reviews it was 295 -> 4870x2 -> 5870 is most scenarios?
Hey, now that nvidia has stopped manufacturing 260,270,285 gtx, so will the new card takes over. Samone know any information about the card / cards and when they is coming ?
Obviously yes, new cards - new performance :P For now they will release new gpu with evga, so will be replacement for old cards i think

Water cooling:
WC HeatKiller 3.0 || 2x 120mm Koolance || Koolance RP-980BK || Koolance nozzles
That's with old drivers.
Pretty much 295 >= 5870 >=4870x2 now.
And I believe in a couple of months 5870 will claim the throne, once ATI driver devs find out how their own hardware works.

yeah but keep peak flops in perspective. rv770 is 1.2 teraflops and rv870 is 2.72 teraflops. something is bottlenecked! i think its off chip bandwidth. they are wasting die space with all of those shaders. maybe cache or a wider bus would help.
the framerate is lower but the quality is higher. fermi will also improve texture filtering. AMD says its free but i am pretty sure that number assumes the whole texture is cached which is unlikely.hmmm are you sure from what i remember from all the reviews it was 295 -> 4870x2 -> 5870 is most scenarios?

Because the 4870X2 isn't twice as fast as a 4870. And since the 5870 is slightly slower than the 4870X2...
No, the GTX295 is faster than the 5870, and while the 5870 does have a near perfect AF algorithm, GT200 still has damn good AF, way better than R600 through RV770. In practice it is very hard to see the difference unless you run that tunnel program that is designed to show the difference.

—Life is too short to be bound by the moral, ethical and legal constraints imposed on us by modern day society.
nvidia does handle AF more efficiently but if you compare the 5870 to the 4890 the hit is much worse. its double the speed but gtexels are the same as 4890? so much for them telling us it didnt come with a performance hit. ATi has historically been known for doing graphics efficiently. this card completely forgets that. SSAA and the new AF are there to prove it. brute force methods like those might be inefficient but the image quality is great. i am expecting fermi to do the same. the cards are so powerful it doesnt really matter.
In case you did'nt noticed.

NVIDIA is scheduled to release ExaScale machine architecture in 2017,Bill Dally,chief scientist of NVIDIA at the Global Road Show organized by Institute of Process Engineering on Oct,27th.The way of introudction of architecture of eight-year later seems a bit of suspicion.However, Nvidias ambition to enter the general-purpose computing market is clear.
According to Bill Dally, NVIDIA will put 2400 throuput cores and 16 CPUs on a single chip with 300W TDP.It is well known that NVIDIA will make CPU sooner or later.This is obvious evidence in definite roadmap at first. However, Huang stresses that NVIDIA will not make CPU, while the Bill Dally also takes Tegra as a shield in answering relevant questions.
This CPU + GPU chip from NVIDIA has also confirmed that they will achieve Fusion in the opposite direction of Intel and AMD.
Each throuput core include three single-precision floating-point unit and a double-precision floating-point unit, the chip is expected to provide a total of 40T single-precision floating-point processing power and 13 double-precision floating-point processing capabilities. Node using this chip also has 128GB of memory, and 512GB of phase-change memory, or flash memory as a high-speed local memory. This node architecture is very similar with current super-computer.Although the figure is amazing,this product can be realized as long Moores Law takes effect.
The wole system is made up of 128 cabinets,which can provide up to 2Efplop computing capabilities with a TDP of 10W.
NVIDIAs future product appears to be powerful.However,Green giant wont give detailed time frame just like the preparation of Exaflop, phase-change memory, heterogeneous processors.

Fermi GF100 to launch by early December
If not in very late November
Fermi, Nvidia's GF100 40nm DirectX 11 chip is selling great even though Nvidia still has to officially launch it. Sources confirmed that Nvidia is taking pre-orders like there is no tomorrow, but at this time Nvidia offers no guarantees when the chip will hit the market. Everyone expects shortages due to heavy demand from day one.
The original schedule of late November might skip in the first week(s) of December, but from what we learned over the last few days, it was always late November to first days of December.
Nvidia ordered much more 40nm wafers for its notebook and desktop entry level chip as well as for Fermi, as Fermi should sell good in the server market for parallel computing, workstation use and, of course, as a computer games graphics card. The server market will be prioritized as Nvidia can make more money on the same chip.
Performance wise, once again we can confirm that multiple sources strongly believe that a single core Fermi will end up significantly faster than ATI’s single core Radeon 5870.

Talk about good marketing when they are able to sell alot of something that does'nt even exist and nobody (except nvidia themselves) know anything about it.

This is really a 'no back up plan' strategy in works. If Fermi is a flop, Nvidia will get slapped really hard, so they better do something already!Talk about good marketing when they are able to sell alot of something that does'nt even exist and nobody (except nvidia themselves) know anything about it.

uh where are these stupid cards (angryface) at this rate ill wait it out till 6XXX gt400/gf200

Nvidia finally gets Fermi A2 taped out
7 weeks into a 2 week process
IT LOOKS LIKE Fermi A2 silicon has finally taped out, so the timetables are a little firmer once again. There is no chance of a real launch in 2009, making the chip a shining example of Nvidia's engineering mire.
Lets recap a bit. We said that Fermi, then called GT300, taped out on about Work Week 28 (WW28), and it did. We said that silicon was due back in 6-8 weeks, and cards could possibly be shown publicly on Oct 1. We admit that we overestimated Nvidia's ability to engineer its way out of a wet paper bag with a map, flashlight and a bunch of wood screws here.
It hasn't shown a card yet at all, yields are miserable, but it did in fact get silicon back on either WW35 or 36, which is right where we said it would be, almost to the day. The fact that yields were a joke, coupled with 'puppy' inflicted own goals, made things downright laughable for Dear Leader and company. Nvidia didn't have enough working dies to do the testing it needed, much less show some off for PR, so it faked that.
Back to the chips. Normally the debug and respin process is about two weeks or so, a marker that should have been passed before not-Nvision. As of mid-October, we heard that NV didn't know what the problem was, and that it was going down the metal stack to desperately try and figure it out. People inside honestly honest green said things were rather desperate.
The latest word was that the chip was set for a WW42 tapeout, or was imminent that week. Let's give Nvidia the benefit of the doubt that it did tape out, something anecdotally confirmed by Fudo saying that the chip will be out in early December. If by 'out' he means A2 silicon samples, then it will in fact be out in December. If you use a definition of 'out' grounded in the reality that humans occupy, then no chance.
Assuming that Nvidia parked a few wafers to speed up the next hot lot, it could indeed have a few A2 chips in late November, and boards to show a week or so later. The go or no-go decision could be made on December 1 if all goes perfectly.
From there, if the risk wafers did not need to be scrapped, you are about six weeks from production silicon, best case. Add another two weeks for boards, and you are into February. Given Dear Leader has scheduled a press conference at CES on January 6th, that should give you a good idea of the public timing. For those curious, although Nvidia seems to have forgotten to send us an invitation to their yawner, it will be at noon at the Venetian Hotel on January 6.
Anyway, if all goes perfectly, we are looking at February for the start of real quantities. There will be A2 silicon before that, but nothing in real quantities. Anyone who says otherwise has ulterior motives or doesn't understand how the industry works.
During not-Nvision/GDC, Nvidia was telling people who mattered and AIBs not to expect Fermi until March. Internally it was saying May, but the AIBs were not told that. About the A2 tapeout time, Nvidia's AIB messaging was changed to April or May.
It would be safe to read into this that the A2 stepping is not going to cut it, and an A3 spin is on the cards. Eight weeks added to early February gets you into March, so that lines up nicely with what Nvidia is telling people.
Another bit of anecdotal evidence is that there is no sign of the other four GT300 variants taping out. Those are usually kept in house until the first chip is fully baked, and the fixes are backported. If A2 would have done the trick, there would have been much more movement at TSMC on the variants, and there does not seem to be.
To wrap it all up, A2 is out, but it took about four times as long as it should have. A3 seems very likely, and the chance of anything more than a PR stunt launch in 2009 is zero. Don't believe the hype, Q1 is best case. When you don't have product, spin.S|A

Still completely up in the air, in my opinion.
Well I guess we find out the 7th...
Did anyone notice this.
EVGA and NVIDIA would like to invite you to a new graphics card launch at the NVIDIA campus in Santa Clara, CA. No it’s not based on the new Fermi architecture… we are still finalizing those details, so stay tuned. It’s a rocking new graphics card designed by NVIDIA and EVGA to take PhysX to the next level.

Does that mean that they are going to launch the GT300 soon?
lol.. I don't think it could say "Halloween Launch Event" any bigger than it doesDid anyone notice this.

That was for the 275+physx card.
I know that too but look at the line in bold. Doesn't that mean that they are finalizing the details for Fermi?lol.. I don't think it could say "Halloween Launch Event" any bigger than it does
That was for the 275+physx card.
For the extremely general definition of "finalizing", yes, I'm pretty sure they are.
I think they're at A2 stepping right now, so it's all going to depend on testing/etc.
