Interesting stuff I'll take a look at it at work.

just got back from the airport and gonna post something from HKepc and go to bed.

It does seem to go +40 even on overclocks.

More info and investigation is needed, but interesting feature. Especially if it has a way of determining max overclock in the middle of a game (different per segment) where you'd seem higher for different parts of games as well as different games (think along the lines of how D3 suddenly made some OCs unstable).

It's not a question of cheating it's a question of being aware of what's happening.

Maybe they hid it to prevent ATi from getting ideas (it's an ingeniously simple idea...run multiple clockspeeds in a core)...I'm sure they have their reasons.

I'm surprised that this is getting more heat than the fact there are only 16 ROPs, but whatever.

It's not really a cheat though, they use 16-bit ALUs to make that happen. We're also discussing here mainly optimizations and hidden features. Intel has always disclosed the ALU trick, nothing wrong here.

Frankly, it doesn't matter how many bits it is or what it does, it's running at a different clockspeed, why not call all Prescotts twice the clockspeed they are? A part of them runs that fast.

Just realize that this is the design of the godd<b></b>amn GPU and that it isn't a cheat, it's simply a part of the core that ramps up under 3D....it doesn't cause any problems and could probably go faster and still not hurt anyone's OC. Anyway, look out later this month for a version of Rivatuner that can individually clock all three parts of the core.

I simply don't understand what you have against a part of the core that runs faster than the rest when it can? And if it can't ever be disabled, do you really care? It adds performance for nothing. If they have a major problem with it, they'll recall it I'm sure.

Anyway, I'm done arguing...you win for all I care, I'm glad nV didn't strap the whole core down to 430MHz and I'm glad they aren't BSing and calling it a 470MHz core (they'd get infinite more sh<b></b>it for that...you'd probably need quadruple bypass surgery after your heartattack and GGA would start seizing).

Oh, and btw, I meant this:
just because it's faster than your card and does something that you're not used to doesn't mean it's bad

Vapor i got a question, so in 2d the card runs at a set speed, at 3d it runs at the 3d speeds, what triggers the card to go to the 40mhz higher 3d speeds?
Click to expand...
Im a dumbarse thats obvious. Did you totally ignore what i said earlier or do you think that I am just that far off base?

With ASUS boards the boards PEG LINK function when set to AUTO allows the board to manipulate the clock speed. It scales as you change the speed of system. I just went into BIOS and made sure that I was set at AUTO. Then booted up and went into the NVIDIA OC software. The clock was sitting at 450. Then I verifed it through the details in PCMark 04. Then I rebooted and changed the PEG LINK to the FASTEST setting. NVIDIA says the same thing, 450. FM however has it clocked at 550. FM is correct. The board changed the PEG LINK MODE to what it considers optimal.

Im going to bed, yall can argue about it until the cows come home 😱

Considering the fact I'm not gay or have even claimed it here, you're already off on a bad start bud.
Bah, what's the point.

The G70 has 16 ROPs for 24 pipelines?!

Oh and for the async clock speed, I think it's just not too efficient to do so, because you're basically doing like running PC3200 RAM on a 333MT bus, it's just not gonna really go much faster as it's trying to get through the bottleneck.
Same thing for the P4 ALUs too, the double-pumped nature of them isn't necessarily very helpful because you still have to find a way to FEED them twice more data per clock to get that part of the pipeline to continue streaming and avoid bubbles. My guess is the initial instruction is 32-bit and is later split, but then the value would be lost as binary code's an exponential growth operation.

Alright, I'll say it then....I'll call you a fa<b></b>ggot regardless of your sexual orientation (I just did) but others I care about a little more might get offended (sorry!) even if they aren't gay.

It's an easy, one word way of showing what you think of someone. I could have called you shi<b></b>thead, coc<b></b>ksucker, a [-peep-]<b></b>er, a douch<b></b>ebag or what not, but I'm in the mood to call you a fa<b></b>ggot. And if you are a fa<b></b>ggot, I guess I was right and you shouldn't get so pissed about what you are.

For some reason I feel like laughing: ROFL... :smile:



So why do you have it against me here?

It's actually a lot of pent of anger toward this forum's bias of ATi. I want to attack GGA, but he's staying surprisingly neutral here.

While this is a small issue (talk about the 16 ROPs with 24 pipes, PLEASE), it pisses me off that GGA makes an informative post and people jump all over its subject matter for being, in some fashion, dishonest. Then you come in and call it a dishonest optimization (I call it a design feature--<b>IT'S ALL GAIN</b>).

Anyway, you're the ring leader of this pro ATi bullshit to a fairly large degree--you know more than most and you're smarter than most....don't let it get to your head. You tremendously help sustain this forum's extreme ATi bias. I don't like that.

There's a LOT wrong with this forum, it's parent site is certainly one of them, it's senior members are another large component. I don't know what 'my deal' is exactly, maybe I'm just getting too used to XS's unbiased, help-based nature and realizing what a crappy forum this is for true advice.

Why I attacked you (I've essentially already said this) is because your post was that fuc<b></b>king feather that broke the camel's back for me. I'm calling you a fa<b></b>ggot because your post pissed me off. Other posts certainly pissed me off too--this entire thread pisses me off because everyone's anti-multiclockspeed stance is shenanigans...there's a reason they have it speed up in 3D (because it can and it helps, otherwise they wouldn't have added that stress) and I'm sure they had a reason for not disclosing it publicly (as I THINK I said earlier, they might not have thought ATi would find this out otherwise--unfortunately, the registers that most major apps use for reading clock speeds read 470Mhz in 3D).

BTW, since the 7800GTX has been released, you've seemed especially anti-nV as your X8x0XT(pe?) isn't top dog any more...that's technology, my 7800GTX will be slower than the R520 come Sept/Oct, I know it will be and don't really care (unless the difference is enormous, then I'll upgrade and the point is moot then).

Maybe you and GGA can take your knowledge and followers and beat to a more even drum.

Fu<b></b>ck off, that entire OTHER forum is full of weirdos that should be in solitary confinement. Whenever one of those freaks traipses up here, something truly repulsive is said...it's disgusting. That entire section of the forum should be deleted and the leaders should be given therapy (or maybe the victims? the leaders should be locked away).

Geez, what's going on here? Everybody getting all wackey! 😱

The G70 has 16 ROPs for 24 pipelines?!
Click to expand...
Yeah, this builds off of the GF6600's architecture (and to a lesser extent what they started with the NV30 [still not enough to say the design of NV30 payed off Anand!]).

The G70's ROPs can each do 2(z-only) or 1(z+colour) opps per clock. Because of this they can replace the usual Fragment cross bar using 1:1 with an adaptive one that allows the pixel pipes to feed the ROPs with enough to keep them busy. This can offer lower overall fill rates, but have higher output rates using just Z, and lower output if colour writes are needed.

Because of the increased time in the pipeline (shader length, etc.) you find that you get higher idle times with 1:1, now this can be 'solved' by reducing ROPs, but like Vapor said it's more of a fab saving than anything else. a 24+24 design will still outperform the 24+16 design, but the areas that may be noticeable in may be so rare as to not justify the transistor expenditure. This also really speaks to the influence of shadows and such which would benifit more from the z-only side of the equation. Fog and blur effects however would likely be impacted somewhat.

It's still an efficient design, but like I said this mhz boost issue is more about the clock-to-clock efficiency comparisons than the architectural efficiencies. And how do you measure the later without knowing for sure the former?

Anywhoo, interesting how this thread kinda devolved rather quickly. Oh, well, back to the grind, and maybe check on a few things at lunch (like mozzartusm's tidbit about the PEG-link).

I don't know what that's supposed to be in reference to, or what motivated it. Kinney's actions last week or somethng new that's got you all hot and bothered? Whatever it is let it out, cleanse your spirit and be free of whatever burdens your soul. 'Cause whatever it is it's obviously eating at you.

i would like to add to that by mentioning MSI/ABIT too has AI(CoreCell/Guru) in their mobos and gfx cards as well. question is, is it all that bad to an average joe who doesnt know or to an
overclocker? purely subjective, but a lil'stable performance boost, when needed, wouldnt hurt et al...in fact, its all good imho...and yeah, its "ALWAYS" nvidias fault in the th forums, lets blame them for all our troubles from here on.

Careful dude, you're starting to sound like Kinney. You wouldn't want that now, would you?
