The Mother of all NV40 INQInfo™ summaries revealed

HERE'S SOME READING matter for you over the long Easter weekend.

More INQInfo™ confirmation
The beagle eyed at Beyond 3D are discussing Nvidia ForceWare 60.72 drivers which seem to have seeped onto the Web at this address.

Confirming our Fudo's earlier story that Nvidia's NV40 will be pitched as a GeForce 6800, the nv4_disp.inf file contains the following entries:

NVIDIA_NV40.DEV_0040.1 = "NVIDIA GeForce 6800 Ultra"
NVIDIA_NV40.DEV_0041.1 = "NVIDIA GeForce 6800"
NVIDIA_NV40.DEV_0042.1 = "NVIDIA NV40"
NVIDIA_NV40.DEV_0043.1 = "NVIDIA NV40 "
NVIDIA_NV40.DEV_0049.1 = "NVIDIA NV40GL"
NVIDIA_NV40.DEV_004E.1 = "NVIDIA NV40GL "
NVIDIA_BR02.DEV_00F0.1 = "NVIDIA Device ID 0x00F0"
NVIDIA_BR02.DEV_00F8.1 = "NVIDIA Device ID 0x00F8"
NVIDIA_BR02.DEV_00F9.1 = "NVIDIA GeForce 6800 Ultra "

A Patchwork Wilt
As we're back on the subject of Nvidia's GeForce 6800 Ultra (NV40GL) we thought you might like to know more of what we know.

Firstly we've received threads of info that the current reference boards in the hands of the NDA gagged, predominantly seem to differ from the engineering samples Nvidia demonstrated at CeBIT, in that they have numerous trace patches and wires running off of them!

We suggest this indicates that Nvidia are rushing around having to fix and hand finish boards just to get these few pieces to its trusted reviewing partners.

Earlier at CeBIT, select people were told that Nvidia were “in production” of NV40, but we're not sure which reality of “in production” they were being pitched with...

Mine's a large slot of NV, with no ice if you can
Sucked from official Nvidia documentation, leaked pictures of GeForce 6800 Ultra have also started to appear on several discussion forums around the web.

These apparently show a board that occupies only one PCI slot, however... we can tell you that, just like those engineering samples shown in the back rooms in CeBIT, most all the products which have just been seeded to the Press and partners - who have been 'encouraged' into signing Nvidia's ludicrous five year (!) Non Disclosure Agreement - the qualification and review samples still encroach on two PCI slots.

Maybe we should call this the NV480?
However, amongst other things, this picture confirms our earlier story when we got our hands on an NV40 sample at CeBIT.

We exclusively reported here that “the primary shocker was that the board requires two large 4-pin power connectors as opposed to the single power connector on current high-end products”.

We speculated that “perhaps a lot of end-users who have been thinking that they might wait and upgrade to NV40 when it becomes available, should start saving their shekels to upgrade to a new power supply unit (PSU) as well.”

Today we can confirm that Nvidia recommends that the PSU for GeForce 6800 Ultra should be no less than a stonking 480W!

And don't be thinking that a PSU bundled with a cheap ass system case or PC typically sold for thirty squid or so will be up for the job

. If Nvidia doesn't produce a detailed list of 'approved' 480W PSU for GeForce 6800 Ultra, then perhaps it should bundle a 480W PSU with each GeForce 6800 Ultra?

No doubt savvy resellers like Dabs or Scan will be rubbing their hands together concocting GeForce 6800 and PSU bundle deals. If GeForce 6800 Ultra ships at say circa £399 ex VAT @ 17.5%, then early adopters who don't have the kind of PSU that Nvidia have in mind, should perhaps budget for another £60 or so. This would mean that the 'solution' price, including UK taxes could be vertical of a whopping £540 (almost a $1000 USD)!

Caught with their clocks out
Somewhere along the way Nvidia seem to have dropped the GPU clock on its 6800 Ultra. This was originally anticipated to be 475MHz but the reference boards are running at a meagre 400MHz. Perhaps Nvidia is thinking 'what's 75MHz between friends'?

This may explain why it thinks will be able to deliver a single slot card which does not feature the heatpipe cooler and centrifugal blower which we, again, exclusively reported upon here.

That said the reference boards currently in the field – bar the patches and fixes mentioned above – do still have the same heatpipe cooler and centrifugal blower as on the CeBIT engineering samples. Though we want to make it clear that these thermal solutions can hardly be called noisy and the centrifugal blower is similar in size to that on the GeForce FX 5950 Ultra (NV38))

One reason why this is the case seems to be because these boards have been shipped to review with memory clocks set at 550MHz.

This effectively overclocks the GDDR-3 video memory - we first reported on this, here – which is rated at only 500MHz.


We've been told, that unlike the leaked images of the single slot variant of the GeForce 6800 Ultra, the heatpipe may be used to aid thermal control of the Samsung GDDR-3 modules.

Apologies that we can't be more distinct on this but we learnt classical Elati not the strange dialect used to describe this feature to us.

Our article here reported upon several eyewitness accounts of NV40 exhibiting "noticeable "artefacts" during performance demonstrations of Unreal Tournament 2004. We speculated whether “the engineering samples memory clock had been adjusted to dizzy frequencies. Frequencies that the Samsung GDDR3 video memory employed, really couldn't hack.”

Although Nvidia claimed this was down to an immature driver that had now been resolved, we think that this new information – that the reference samples are apparently running overclocked memory – again makes us wonder whether we were so far off the pitch...

Perhaps the single slot thermal solution pictured in Nvidia's leaked documentation is for later (much later?) GeForce 6800 Ultra variants which will have proper GDDR-3 rated at 600MHz? Perhaps when those 600MHz G-DDR3 modules do become available, there will be GeForce 6850 Ultra that just bumps up the memory and GPU clocks for a fall refresh?

Everything out of the Shaders
So, 220 million transistors, 16 Pipelines, 400MHz GPU clock, 550MHz memory clock, memory specifications, thermal power of circa 150-160W, thermal control designs, power requirements, retail product name, product briefing dates, launch dates, retail availability and 3DMark 2003 performance scores, what other fundamentals haven't we reported? Ah yes, the final part of the NV40 puzzle we can reveal today, is that it has has six Vertex Shaders.

Honour and trust
Here at The INQUIRER we're presently happy to leave the detailed analysis to others who in some specialist areas - such as 3D graphics – are eminently more knowledgeable, perhaps than even our Fudo. Presently, the best we can normally do is bring you guys what any manufacturer tells others.

I've been given the heads up on a lot of stick Fudo was receiving, for simply reporting stuff that he was told by numerous reliable sources. These reliable sources had been provided with this information directly from the manufacturers.

If manufacturers are willing to feed their own customers red herrings in a campaigns of FUD and spin, well how much trust should an end-user place in any of these companies, and the claims it makes publicly? Basically what I'm saying is that if these companies are willing to bullshit their own 'friends', then in an effort to extract a wad from a customers wallet, would they not be prepared to bullshit them too?

I'm increasingly thinking that perhaps this whole NDA nonsense needs to be rethought by the graphics companies when it comes to dealing with the Press. We've had in hand a bit of info regarding ATi's next gen 3D accelerator that I was just about to write up, but today we were given the heads up that Anandtech had broken that embargoed information in this cool news piece here.

Before we even started our INQuiries into NV40, and at each stage on the way, we have offered Nvidia numerous opportunities to brief us. I even suggested that unless information subsequently came to light through a third-party, I would honour its embargo date on elements of information discussed if I was convinced that publishing it would compromise its commercial advantage.

Nvidia refused to do so, but never explained why. I took it as a simple issue of trust. ATi did bother to explain its policy and said that its NDA requirement related to Selective Disclosure. However Nvidia did put us right on one small detail on something that I had mistakenly reported (sorry guys I was tired and hungover..) on the proviso that I agreed not amend my original article. I have honoured that agreement with them, and always would do so in every instance. Yet Nvidia still refused to brief us.

Nvidia, to its everlasting credit, doesn't try and throw any of us off its stands at CeBIT any more.

We are delighted that this is the case, and most every Nvidia face I've dealt with during the past few months had a smile on it that I was welcome to see and in the main believed was sincere. As my editor said last night over a damn fine Thai meal and a Singha beer or two - ironically courtesy of ATi Technologies - hacks just don't like being controlled and told what to do. [Are you sure I said that Paul? Ed.] µ

If Nvidia doesn't produce a detailed list of 'approved' 480W PSU for GeForce 6800 Ultra, then perhaps it should bundle a 480W PSU with each GeForce 6800 Ultra?

***** dia saem com fontes de alimentação...

Ao k parece a placa não vai ser nada má, em relação a ser superior á r420 ou não só com as duas cá fora mas parece inovar em relação á sua irmã mais velha...

Será k vamos ter nv40 em São Francisco dia 13 com overclock a correr o UT2K4???

Na volta akele akeles artefactos é pk tavam a usar o LOD bios e eskeceram-se do desligar pois vinham d1a ronda de marks os quais foram publicados anteriormente sem quaisquer imagens do mesmo LOL


Há rumores de release date da r420????

26 de abril a Pro e 31 de maio a XT. Provavelmente dia 26 fazem o "paper lauch" da XT.

Quanto à NV40, entre 150 a 160 W 8o. Se verdadeiro, isto é um bocado ridiculo.
 
Será que temos uma nova parhelia a nivel de clocks? (inicialmente 300 a 315 e depois ficou-se pelos 220).
Esta 6800 Ultra,
No artigo da Maximumpc : Core -> 500 a 600 Mem -> 600
Gdc : Core -> 475 Mem -> 600
Placas que foram para os reviewers : Core -> 400 Mem -> 550

Eles ainda não divulgaram os clocks finais (só dia 13), mas se for o mesmo que as dos reviewers, se calhar ainda vamos ter a X800 Pro (12 Pipes) a ficar lado a lado com esta Ultra. Para ter o mesmo fill rate basta que venha com 533 mhz de core, o que não deve ser impossivel. Falta saber os mhz da mem da Pro.
Vamos lá ver o que é que a ATI tem.
 
é mais um Wblock pra juntar ao watercooling....

isso dos WAtts.... preocupa-me mais que sejam no Cpu...
Porque numa grafica, eu nao passo 24h/dia a jogar... se forem 4h ja é muito, logo a conta electrica ou "calor" da placa nao me vao afectar...

no maximo aumenta a temperatura da agua alguns graus (mau pro cpu), mas se forem placas realmente rapidas, compensa perder 3 ou 4º....



Edit: se mesmo em Idle ela for muito quente... faço o mesmo que faço na minha 9800pro...
quando precisar de jogar meto a 490mhz, quando nao preciso desço pra 290mhz...

Mas a mesma logica vai para para o CPU. Quanto tempo tens o cpu em load ou em full load?
A não ser que tenhas algum prog 100%/24horas.

SETI.... e muito Prime95 (tou a condicionar as mems..)

qualquer coisa que faças, é CPU..... Mas em Windows na grafica so mesmo o ramdac ta a funcionar, e este nao faz "gastar" 150watts...

por isso nao me preocupo muito com os watts da Grafica... a minha 9800pro a 490mhz Vgpu 1.95 não deve andar muito longe dos 100 e muitos watts, e só lhe tenho um dissipador aluminio de um AMD 1800+ tbrebA...

só é lixado por causa da fonte... precisa de 2 cabos independentes (um molex por cabo... )... mesmo assim, a minha fonte tem 4 cabos.... i'm ready :D

Ok ok. Assim é diferente, mas se for verdade que por exemplo a NV40 faz decoding/enconding de uma data de coisas (não me lembro quais eram), a coisa já é diferente.
Veremos........deve ser engraçado um precott com Oc com um grafica desta geração tb com Oc, mais todos os outros componentes.
As Antecs deste mundo devem estar a esfregar as mãos de contente.
 
Oh se tá! :D O que vale é que ja nem é preciso comprar aquecedores para quarto/escritorio! :lol:
Esperemos que os preços das 9800 XT venham por ai abaixo! Fingers crossed! :009:
