They are lazy because there is no one to fight with. 5990 and 5870 EF 6 are coming and so are custom designs of 5870 with 2gb and 1gb.Quote:

My last off topic here, video ram does decrease available memory address space which in turn limits available address space for system ram with a 32bit OS.Quote:

This is, hopefully, the final installment of "The Fermi Thread". As before, this thread exists as without it the news section is overwhelmed by Fermi-related rumors, the majority of which are entirely without substance.
The Rules:
- This thread is about Fermi and things related to it only
- Do you know something about Fermi that isn't here? Post it!
- Don't play with the tags. We can track those and depend on proper tagging for search engine traffic.
- Play nice or you'll get the hammer

If anyone has links to nVidia they feel are credible / official news feel free to send me a PM and I'll review and toss it up. Seriously, I know there is more info out there than the outdated stuff I have below!

So the only difference between them is the bus width and 32 shaders? 32 shaders don't mean anything performance-wise. If it's the bus width that will distinguish the two cards, it means the 470 is bandwidth limited even at 600mhz which I don't think is possible.
I think 480's clocks have to be higher.
just moderate anything that starts with i think or relies on unsourced information. should be managable then :)Quote:

So, diesize is around 530 mm^2, like what has been told by Charlie for months, who would have thought that ? LOL :rofl:Quote:

how about this nvidia wasn't sure which one to use ? since not only charlie changed his info but many others too :ROTF:Quote:

not for nothing but i'v see both sides rave about their new up coming drivers with fancy slides,then so so results on your pc.
it would be nice if ati let you make you own game profiles thuo..
ATI Tray Tools lets you do that and so much more that i gave up completely on CCC. I only install the driver and let ATT do the rest :up:

By that I mean, currently, when SLi is enabled, you only get 2 displays, and one must be via HDMI, thus is is limited to 1920x1200.
It seems that ATI is ahead of the game here, as I've been told that with Crossfire, you could have 3 displays, two of which are 2560x1600 and one that is 1920x1200.
Granted, you only get top performance on one, which is all I care about, but having 3 displays is making ATI seem more appealing (strange for me to say that after having NVIDIA cards for the last 10 years).
Any rumors on this changing with Fermi?

You do have to use one as display-port for eyefinity or 3 monitors, as one of the DVI's is shared with the HDMI on a 5870.Quote:

3) i run two 1920x1200 screens and ATI **STILL** hasn't sorted out the flickering issue on the second screen! That's completely unacceptable close to 4 months after launch! They may have eyefinity but when the card is in low power mode (ie most of the time) it cant run two screens (my damn 8400gs in my work machine can but obviously its too complicated for the 5870)! I had ordered a 5870 then i read about the issue and cancelled my order and am still waiting for it to be sorted out...
If the 480 launches in the $450~$500 price range I will buy one as there is no other choice, simple as that.
No way it will launch with that price. Even if it's MSRP, I expect artificial reseller markups to compensate for any reasonable prices on these new cards.Quote:

ATI should have more room to compete, especially if their yields start to improve.
All I can say is, for $500 it had better kick the 295's butt. I'm not anti-multi GPU like some are. I'm "pro best performance for your dollar." I know that multi-GPU setups have adversaries out there that would pay a good deal extra to get 295 performance without the dual GPU. I know some have had issues. Heck, it took me FOUR GTX 295's to finally get one that works!! But boy does it work good. That's why you just buy from someone with good service and a good warranty!! :D

no.

Please keep in mind, that what he hyped up was non the less the Uniengine benchmark results, which was what nVIDIA showed up (remember the 60 seconds screenshot slide?). So, yes, he was reliable.Quote:

He was right about the Gemini being a x2 card before others got wind of it.
He maybe wrong about GTX 480 having 512SP units tough.
Also idk if it has been posted yet or not GTX 480's main feature aka Tessellation relies on SP's and this has been told to me in 2 separate occasions. Now the 5970 has fixed tessellation units and it would think they perform better then the single tessellation unit in 5870. Now the GTX 470/480 has a variable tessellation unit who's performance varies with load.
The GTX 480/470 also has fixed tessellation unit but it is not the one that makes fermi all powerful in tessellation heavy environments.

Never had any of these with any modern nVidia card, 7900GT onward through 8800GTS 640, 8800GT 512, GTX 280, etc. so I'm more confident in Fermi from my experiences, whereas the 4870 + 5870 have both disappointed me.Quote:
Windows 7 x64. A few examples include, but these aren't all of them by a long shot:
1) Street Fighter 4: Fences and flat background textures such as those on the "Underpass" fighting stage flicker depending on camera movement.
2) World of Warcraft; Warhammer Online (WAR): Many grass items flicker or become "transparent" partially while walking around.
3) Desktop of Windows 7: Occasionally I get green dots only in 2d mode on dark parts of my wallpaper, sometimes they're red. I have tried a different DVI cable (monitor is a 2560x1600 Dell 3007WFP-HC). This never happened with my GTX 280.
4) NFS Shift: Colliding with the walls or other cars more than a couple times in a race, even bumping them, would cause massive slowdowns as it stuttered slowly for a couple of seconds, then would "catch up" displaying frames rapidly as though it was in super-speed before returning to normal. This occurred with the 9.10's and NFS Shift patch 1, and is much less severe with Patch 2 and 9.12's but still occurs at times.
5) CounterStrike Source: There's a fog regardless of settings that fades things to gray a little in the distance.
6) Warhammer Online (WAR): Some characters and tents become transparent and detailed in only their basic textures randomly. Moving the camera fixes it; if the character moves, it remains a "ghost". I have tried swapping in an 8800GT with the same game version and do not encounter these issues; the ATI versions with my 5870 I have tried exhibit it.
7) Dirt 2: Enabling anisotropic filtering through drivers causes slideshow performance.
I also have a lot of texture corruption (random textures appearing on random objects instead of proper ones) in WAR and WOW when "adaptive MSAA" (transparency AA) is enabled, and additionally, the forcing of driver AA/AF doesn't work in some games, or just disables any in-game setting while not applying anything. There's a zillion little glitches/issues like this with the 5870 drivers even with 10.2's now that persist. In short, my experience with modern ATI cards has been that they're fast, but certainly not good. Hence, I am VERY much looking forward to getting back onto an nVidia card with Fermi.
I don't get why 5970's double fixed tessellation units should have to do with anything. It's not like one tess. unit of one GPU can help the other. They both help the GPUs they are in. Performance scaling shouldn't be different when there's Tessellation than when there's no tessellation.
Saying the second tess. unit should help in tess. heavy environments is like saying the additional 1gb of RAM in 5970 should help in 2560 + 8xAA.
if lets say a game uses alot of tesselation while at the same time uses alot of something else to render a scene this would mean fermi would be put down to its knews right ????
and the 5000 series with its fixed tesselation unit would run it decently right???
mature explaination welcomed!!!!
RAM is used for mirroring data but tessellation is used when rendering. SO its logical to assume that the tessellation unit will help GPU 0 to render half of scene while the other tessellation unit will help GPU 1 to render other half of scene.Quote:

I'm not being "an*l" I only posted it once here, at the end of the last thread in response to someone asking for it when I mentioned I had 5870 issues. The thread was locked so I posted it back in here so we could continue our discussion. The original quote was made at a different forum by me that I copied/pasted. These aren't minor issues that I am being "an*l" about and nitpicking: these are major visual glitches/errors that are persistent and constant, as well as other stability issues not listed. There's many many more that would be "nitpicking" to most people, believe me... I don't consider flickering bushes, being unable to force AA/AF in some games, etc. as "nitpicking" and I sincerely doubt many would.Quote:

In short, in my personal experiences, the 5870 drivers are mostly garbage: they get the card to run, but it looks like cr*p while doing so. As I said, I'm very much looking forward to being back on an nV card without all the rendering errors. In short, just because you disagree with my opinion and haven't personally had the issues doesn't mean many don't: no need to try to minimize me and claim "oh he posted it a buncha times, must be trolling!" when no such thing occurred :).
Anyway... 26th is NDA drop, anyone know if any cards will be available then or is it the 6th as rumored for being on newegg/et. al :(?

So, NO! The tesselator in GF100 is not a pure SP one, same as ATI is not pure fixed function! Those are myths created by Charlie and ATI FUD machine.
i like to think of the $ per mm2. yes the 4800s were cheaper when they were released, but they were also alot smaller than the 5800sQuote:

they are practically identical comparing their release prices. both were not the first they did on the node (55 and 40nm) and both are the biggest they did on the node. so theres alot of similarities between when trying to think of the simplest cost and revenue potential. based on this its pretty safe to say they were priced competitively, and there is room to drop prices now that this card is quite a few months old. if fermi came out at the very end of last year, then we would have seen prices drop then, slowly over time like normal markets. but since its a few months later, AMD could either drop it a massive ~30% to make up for the lost time, or kinda let time skip, and start a slow price drop from here on and enjoy their last few months ahead of the curve.
What gets me is that people are saying fermi does not have a dedicated Tess unit. Can anyone explain why by specs it has approx 3 times as much triangles than the 5870? Is this assuming shaders are used and how would 3 times more triangles not be better with dx 11 tesselation?
Alright, Zed_X came here exclusively to "leak" about Fermi, so I did a bit of a trace:
5-jan-2010
NVIDIA at CES: GeForce 3D VisionFinity and Dark Void PhysX
At CES will NVIDIA to demonstrate new "(nV)Eyefinity" technology :D (true)
Three displays with GeForce 3D Vision and Dark Void PhysX game - on ONE Fermi card! GeForce 3D Vision and Eyefinity together (false)
All of you will see what is Fermi in TWO days,...
All of you will see what is Fermi in TWO days, and someone will be hardly surprised :) :) :) Performance is BRUTAL! (false)
7-jan-2010
No one reviewer will get GeForce 300 this week, NVIDIA will send samples later in february. But they will have many infos about GeForce architecture, features, performance - but no CLOCKS! In few days NDA lifts (someone will leak it, for sure) and every server will bring article about it, be patient. (true enough)
9-jan-2010
GeForce 380 has huge :) power consumption (true), but performance is only few percent under HD 5970 and far away from HD 5870 perf (false). Trust me, will see next week on many servers, when NDA for info lifts!
NDA will lifts few days after 14th, today is main GeForce 300 Deep Dive meeting. I can say this: GeForce 300 has higher perf then GTX 295 with lowest power consuption. Look at GTX 295 vs HD5870/5970...(at this point, I say false)
11-jan
Every invited journalists has complete Fermi Geforce slides now, NDA will lift in few days, but i hope someone broke it and publish something on B3D or somewhere in Asia like always. If you want to know +/- perf. look at my previous post here in this thread. Dont worry about TDP, on CES are only first silicon unfinished products, remember first black press samples 4870X2 with TDP 400W? (true about NDA, likely false regarding TDP)
12-jan
Deep Dive meeting has over, and we already know how powerful GF100 is, and IT IS! Performance is better then expected, most peoples here will search in own words and feel to shy for craps in thread....(false)
that TGD news is bull:banana::banana::banana::banana: (it seems they were not invited), i told you before a WEEK, there will be NO CLOCK, TDP info fo journalists (am not a journalist!). (I'm saying false, everybody is saying 270-280w for GTX 480 today)
You are wrong, Deep Dive was not "Fermi architecture white-papering", like in October was. Every info are brand new, every slide talking about perf in real numbers. I am sure, no one will be (false, Farcry 2 was the only performance number we had)
13-jan
his screen i found on TPU forum, represent GF100 power truly REAL!
http://www.czechgamer.com/pics/clank...6-19_fermi.jpg
Between 20-23 percent above HD5870 and only little under HD 5970(false)
24-jan
thats all is BS, For Surround are needed TWO VGAs in SLI, not only ONE GTX 285, this graps says "estimated" performance, not "measured". Absolutely nonsens
PS. For 3D surround you need TWO GF100 too, not only ONE (true, correcting himself on the 5-jan claim)
Hehe, you are wrong like always. You meant poor launch availability of Radeons HD5870 and no buyable HD5970 till today, dont ya? For launch, will be enough card for enthusiast! (remain to be seen, though I can't believe that GF100 will satisfy enthusiasts' demand)
15-feb
NV finally found final CLOCKS of GTX 470/480. Cards are ready to launch, will be in second half of March in reviews. There is one word: Gemini, when GF100 will be launched, remember for that word!(true)
22-feb
Tomorrow will be exciting date, for fans! (false, it was anything but "exciting")
launch is still in Q1/2010 :) (true)
23-feb
GTX 480 has 512SP, i thought it is a taken as a facts, where are you was last few weeks/months triniboy? (false)
7-mar
yeah FAKE, frequencies are higher ... more higher
PS. GF100 is fully supported in 196.75 (ID removed from inf), and final release of driver is 196.78-196.80 NOT 197.xx
PS2 - i am guarantee, last GPUz did not recognise GF100 cards
(we'll see about this)
12-mar
Yeah, GTX 480 is not competitor for 5970, but 5870 :) This is not NEWS. (again, contradicting his earlier post)
Against 5970 NV has planned dual GTX 470 (we'll see)
To me, the guy seems to have some real insider's info. But his view point is rather ... inflated. He hyped GF100 as least as much as giving out some info about it.
Well, good job at pointing out some of the mechanics of how tesselation works, but you did fail to mention the singular reason why the 4xx Nvidia hardware will ALWAYS have a huge advantage over the ATI 5xxx series in tesselation. You did part of the work for me, mentioning that this was a 3 stage processes but left out the most important detail, in ATI 5xxx hardware, this is a multipass operation which requires it to go out to board memory and back the core at least once, and more depending on how much tesselation is used, this slows down the process considerably. Now on Nvidia 4xx hardware, it is also a multipass operation, but due to a unified cache architecture it doesn't require a trip out to main memory for each pass, only a trip to on chip cache making very significant gains over the ATI 5xxx series on tesselation, this also caries over to big gains on any multi pass shader such as some of them used in Crysis.Quote:

I said fermi has both hardware based fixed tessilation unit as well as the ability to use SP's for tessellation. The scores you see on Unique are a result of that, one does not need huge tessellation processing in games "at least for now" so in this case Fermi will use its hardware based tessellation unit. But once the tessellation load gets heavy enough they may use SP's to do tessellation.
The end thing i want to point out is Fermi's BIG thing is tessellation power it carries and the flexibility it offers. Fermi owners maybe in luck if next gen games use tessellation more and require less raw SP's to render. If one looks at Unique one can notice that it slows down quite a lot on 5870's when a scene with heavy tessellation is rendered "dragon" but in such a scene there is lesser use of its SP's because the tessellation unit is loaded to the max.
yeah, because this guy is insider :)Quote:

Do you know anything about GeForce GF100 GPU versions ready to ship or about to ship in the near future?
Is GF100-375-A3 a 480SP version?
Is GF100-275-A3 a 448SP version?
Is there a high end 512SP GPU version?

Could Windows Vista/7 coarse context switching affect the multi GPU tessellation performance?

According to our dear Charlie, nVIDIA has tapped out GF108:
Even with somewhat good news, he cant resist to make it look bad:ROTF::Quote:
GF108 is what Nvidia taped out, so its triumphant vaporware GF100 is indeed going to be followed up by a huge wave of GPUs, all of them low end.

At this rate, Nvidia will have a full line of parts, in quantity, but not until Q4. Q4 2011, that is.
Ok, good point, the whole fixed function tesselator discussion is a bunch of BS spouted by people without the first clue how the process actually works.Quote:

By Q4 2011, Nvidia will have the first 28nm GeForce Fermi based cards at stores.
You need to make up your mind, does Charlie post news or not? It seems when it's news you like, you're fine calling it news. Selective reading 101.Quote:

but Q4 2010 is horrible .. its 1 year after the official announcement right ?? :|
I'm afraid Mr. CD proves right even when he's joking.
So just in case I had to write it.

"Windows 32bit" will only see and utilize no more than 4 gig (just a little under), but all the other programs installed will use eveything available. So when playing a game, it is not windows 32 managing the memory, but the game itself and the hardware in question (which is sort of a program on its own).
So basically you guys are half right and confuse.
Everything will be in use, but windows 32 will only use what it can, 2 different thing.
Very scalable architecture indeed! :clap:Quote:
