Nvidia's Chief Scientist, David Kirk has suggested that "People just don't know as much as they think they do" when it comes down to the "Many" clocks within the GeForce 7800, aka G70.
"It's somewhat hard for us to say 'the core clock in G70 is this single number'", says Kirk. "We didn't want to be accused of exaggerating the clock speed, so we picked a conservative number to talk about the core clock speed. But, yes, that is just one of the multiple clocks." David's comments come as he speaks exclusively to bit-tech about the issue which has become a hot topic amongst the community over the past couple of days, following the discovery that RivaTuner was reporting varied clock speeds for the 7800. We met with David in central London today, and he talked to us about many different issues. We'll have the full interview for you tomorrow, but we couldn't sit on this one until then. "People have said that G70 doesn't have any new architecture, but that's not really true. It has new architecture, it's just not always visible. "The chip was designed from the ground up to use less power. In doing that, we used a lot of tricks that we learned from doing mobile parts. The clock speeds within the chip are dynamic - if you were watching them with an oscilloscope, you'd see the speeds going up and down all the time, as different parts of the chip come under load." _______________ Read More/Source: Bit-Tech

"So why haven't we heard about this feature before?"
Becouse they had something to hide or didn't know how the entusiasts would take it. If it hadn't been discoverd and reported by the right people you still would never know about it. If it was such a usefull "feature" expect it would be advertised and given a flashy name... Why would they hide somehing that would sell them more cards??? (probubly dynamically over clocks it self based on temps)

I would have guessed they were using a version of AMD's Cool and Quiet except for their silence. I can't help but think they are somehow pulling another fast one based on nVidia's past history. If their driver is reporting one clock rate when it is really adjusting/overclocking the card (without notice to the end user), that is just as deceptive as reporting DirectX 9 shaders in benchmarks and replacing them with DirectX 8.1 shaders.

Last time I checked my PC was plugged into the mains and not ran on batteries. I couldnt give 2 flying monkeys about powersaving abilities, my electricity bill is hardly crippling me. When I switch on my PC I want cold hard power I'll leave the powersaving crap for my 3 laptops

Why do you think they are trying to hide anything? Maybe they figured it was no big deal.
Why would it matter any ways, other then the card being faster then anything from ATI right now? Don't worry we all know ATI will jump ahead of Nv when they release their next card, then Nv will jump ahead when it releases it's next card and on and on and on. The only one who wins is us, the customers. I don't see what the big deal is/was, please explain why having more then one clock is pulling a fast one or what they are trying to hide? No offense but it sounds like your trying to find something/anything to make the fastest card out slower ????

Im sure you'll find the only ones who really win are the manufacturers accounts department. Lets finish this generation before we start on the next one.

I live in North of England where it's always cold and im half deaf from firing pistols, throwing flashbangs during house clearances, launching artillery strikes and driving tanks so this time im afraid it's a definite no

Nothing to hide, they just tried to keep in under wraps to prevent ATI from copying.

the card is kicking butt. what is the problem? sounds to me like they might have more room for a speed upgrade when ati eventually does their release.

I guess really relying on overclocking now is a little bit of a mute point. I mean my MB can overclock(and underclock) my machine by up to 15% on the fly. I'm guessing looking at clock speeds for VPU's are going to go the way of the CPU's. Clock rates start not meaning dick all.
Which means confusing the hell out of people yet again when they want to buy the best card. |

In the end all that matters is the IQ and the number of frames that are being pumped out. I don't care if NVIDIA is telling me their cards are running at 5 MHz/20 MHz, if I can play my games at 1280x960 with IQ settings up at 60+ FPS, then I will buy it.
Like MSX said, clockspeeds are beginning to mean nothing.

Wouldn't it be hard to make a change at this point a few mounths before they ship?
Hmmm.. auto overclock acording to temps it kinda like overdrive iver reverse! Overdrive for the X850 reads the temps and keeps your set overclock If the temps rise it will lower the overclock to protect the card. their soultion is in the hard ware , is not disableable, sets the card to stock, then overclocks when a 3d application is opened according to temp Wich is EXACTLY like ASUS's AI wich is done via hardware (ASUS is nvidias b***) over clocks then a intensive application is run. So its not exactly "orgional" So saying ati might copy it, the qestion is who nvidia copied it from Asus? or reverse ATI? To me they just copied the idea from asus Quote:

I wouldn't say they copied it from Asus since their mobile parts have done some thing similar to this for awhile.

setting right next them. I was there for at one such event. Thats true Intel and AMD mobile CPUS have done it too again before nvidia. So much of it being "orginal" though... They down clock to censerve power when the cpu isn't being fully utilized. The but cpus aren't sold at one clock speed and they don't self overclock behind the scences. something that if impmented wouldn't have to be copied form them like they like to say even when ATI is 1st in introduceing something. people still say they copied... None the less if there wasn't something to hide they would of annouced it... isted of makeing it look they jumped so much with just a 100mhz more memory, and 30 mhz more core... improvement over the 6800U Also it likely to verry from card to card so that too could not make buyers happy. Trying to make thier hardware look so much better at 430 mhz, like they actually impoved the desighn alot insted of simply getting better clock rates . Its a matter of pulling the wool over the consumers eyes like useal with them.

because they did not know that, as usual, everybody with the capability was going to be analysing the card to the outmost of their ability & nobody would be able to figure out that something was going on? please.
wha texactly are they hiding? does this have anything to do with your evil empire theory? do not get me wrong, i am really curious as to reason & effect of the differing speeds. they probably made a pr mistake in not announcing it, but until we get all the facts can we please not jump on the big, bad conspiracy band wagon?

Evial empire thery? If I had to give Nvidia tatics since many years ago has been if I had to put a name on it it would be "smoke and mirrors"diverionary tatics and tricks, wich can also be seen as deceptions wich thier good at. lieing, hideing things form you, doing stuff that could be considerd unfair pratices but tricks & deceptions covers it all. "smoke and mirrors" man "smoke and mirrors" Their logo should be have you been douped today? Quote:
430 mhz core they would have been advertised a "470" but there is more then one clock rate it possably can run at... It not advertised and if rivia tuner hadn't read the correct registers we wouldn't be talking about it now! You still wouldn't know about it. Maybe never would of or at lest not for a long time. especailly since they wil get the tools to repart the allways accurate clock speed of 430 at all times The cards are not as advertised being 430 mhz all the time. To make the card look like they made a leap in design as oppsed to a leap in core clock rate since thier finaly uses process like lowk used by ati for years. They they said were "dangerious". Wich would be be more apt to buy? 1) A card thats a magor improvement in desighn and decent boost in performance? Small clock rate change over pervious genertion but big performance boost, Wow!2) A card thats a minor improvement in desighn and decent boost in performance? Clock rate change over pervious genertion = the resulting performance boost, oh!As in a overclocked card would displace alot of the need to bother upgradeing... I mean If your runing a 6800U/X850 there would far be less buyers that think they need to jump on thier G70 banad wagon. There was less of a chane then thier letting on it seems.

what i dont like is the claims of sneaking/cheating. if the cgpu runs at that higher speed in bemchmarking & gaming then it is not cheating. period. but until we get all the facts none of this really matters because we just do not know. i think it is a kickass(though overpriced card) card that is going to get faster down the road. i think some people have sour grapes about that.

neon, the card is much faster, period. you cant 'dupe' people with 'smoke & mirrors' into beleiving that.
like i said it was a foregone conlusion that somebody was going to figure out what was going on. somebody ALWAYS finds out.

In my honest opinion I think neons got a long standing hatred on Nvidia and any HINT of anything untoward he jumps on and makes a scandal, we still do not know whats fully going on here, or in fact how the G70 core works, to be accusing them on scant evidence is setting yourself up for a fall neon, wait for the facts, the FULL facts, then you can flame away, until then, you're making yourself look quite foolish and biased.

still think the card is runing a 430 MHZ all the time as "advertised" by sellers and by reviewers who were unaware of this hidden fact. Othen then that it seems the over clocking is limited. Becouse If you dro better cooling on the GPU like watter cooling / promethia etc and if the temps drop below 50C the gpu foces down clocks and protects it self. wic is something thier working on fixing

[color=White]"Even if you overclock your GeForce 7800 GTX towards 500 MHz the actual realtime monitoring results would show back 540 MHz, again that 40 MHz difference" There is more to this than you know neon, there ARE clocks that stay at 430mhz in games, there are others that move up, if they said it was a full 470Mhz you'd be saying "OMFG not all clocks are 470MHZ, some stay at 430, MIS-ADVERTISING!" right now, Read this, realise this issue isnt as open and shut as you'd like, and wait to see what pans out, ok?
