Kepler Nvidia GeForce GTX 780

[GoldenTiger]

So, the GTX 780 has finally arrived, and no one really cares 'thanks' to the GTX Titan.

Not sure where you're getting that from... most people won't get theirs until this coming week due to shipping.

So, the GTX 780 has finally arrived, and no one really cares 'thanks' to the GTX Titan.

Given there are OCd versions that outperform Titan for gaming, and even the stock ones are ~10% less performance than Titans for 2/3 the cost, I think a lot of people "care".

I'd think anyone in the market for a high end gaming GPU would only consider a 780, unless they're a 1080p gamer and just can't spend over $400.. Those guys should nab a 7970.

how did you arrive at this conclusion? mine is overclocking quite well. A stock 780 can boost up to 900mhz... mine is boosting up to 1241mhz. That's better than my Asus 670 TOP. That's a 38% gain on clock speed, my ram is going up to the low 7ghz range. Thios card is by far the most fun i've had

Well its very possible that they integrated bridges on die that are cut in the binning process, nothing to alter on pcb or via driver hacks.

The amount of work it would take to cut all of those bridges (it's not just one tiny bridge or something) would be incredibly cost inefficient. Also, if you understand how Titan can do FP then it's clear that it's a software switch that allows it to do FP64, if the "hardware bridge" was cut it wouldn't be able to do FP64 at all.

There is one other quirk to Titan?s FP64 implementation however, and that is that it needs to be enabled (or rather, uncapped). By default Titan is actually restricted to 1/24 performance, like the GTX 680 before it. Doing so allows NVIDIA to keep clockspeeds higher and power consumption lower, knowing the apparently power-hungry FP64 CUDA cores can?t run at full load on top of all of the other functional units that can be active at the same time. Consequently NVIDIA makes FP64 an enable/disable option in their control panel, controlling whether FP64 is operating at full speed (1/3 FP32), or reduced speed (1/24 FP32).

So it is clear it's simply a software switch and there is no reasonable way to hardware limit to 1/24 speed.

during the next 3 months, and this is exactly what are doing Nvidia ... sold them thoses next 3 months. .. Im sad allready for them...

Don't be sad for 780 and Titan owners, as my son would say "they are beast cards".

Not cheap cards, but very good cards.

[kromosto]

if nvidia was released 780 as 680 then there can't be any bundles that make me but 7970ge but 780 is not 680 and it is a bit late. while it has significant boost over last gen cards, there are still a very few games that make you thinking of upgrading from 7970ge or 680 to 780.

[TurboDiv]

That 780 looks really good thanks to the overpriced Titan ! At this moment the Titan is just a benchmark toy. In real world gaming, the difference of 2-3-4 FPS will not be noticed. I predict Titan will slowly disappear from the market. They milked it first since they know that 780 would be the preferred card. Of course that's just my opinion. I hope we will be getting the modified 780 boards soon !

Tony Tim Logan pretty much confirmed there is a MSI lightning gtx 780 coming out and already has one.

Supposedly some higher ups in EVGA have confirmed that there won't be 6GB 780s coming out.

If you or anyone here understood how it works then you or somebody here would know how to enable or disable it, there would be no discussion.

So what is clear at this point is you nor nobody else know what to do no more than anybody else here.

Doesn't matter how its locked or unlocked, once somebody has done it for sure we will know...

I'm a hardware engineer, not a software engineer. All I can say is the hardware is there to do it, the software switch has to be flipped. Is it a matter of PCB resistor values (like Tesla vs. GeForce)? Is it a matter of BIOS card ID values? I can't say for sure, as I don't own a 780 and I can't fiddle around with the drivers. It doesn't mean I don't know anything about it saying "you haven't done it, therefore you know nothing about it" is not a valid point. I know that there is the same FP64 hardware, it just needs the driver switch to allow them to run at their full speed, and it would be very difficult, if not impossible, to somehow "slow down" the hardware to 1/24 speed.

But yes, until someone actually makes the switch it isn't anything absolute. I'm just saying it's only a matter of programming, not hardware.

That is true. Jacob with eVGA confirmed this already. However, he did confirm that nvidia is allowing custom PCB off of this card, so they may do something later on.

Is there a way to read and write the vBIOS on the 780 cards yet?

Can't get it to work :/



Tried via latest nvflash for DOS as well, same issue.

Running a EVGA 780 SC ACX.

Regarding the fact that the vBIOS is posted in the techpowerup vBIOS archive, it has to work (at least reading) in some way.

Depends what your resolution is and if you want to run Crossfire or SLi. I'm re-thinking that lately, liking the feel of a single GPU again.

At 25X16 a 780 or Titan is almost a necessity.

[Rollo]

It would pretty much end the Titan SKU if there were 6GB, OCd 780s.

Have you tried this tool? Doesn't mention GK110 support but it can't hurt to try.

[ralle_h]

Thanks, the thread you linked gave me a golden hint idd:

You will need to extract your bios from your card with this version of GPU-Z

Finally I was able to read out my vBIOS with the old GPU-G 0.6.4 and edit as desired:



Now I just need a working nvflash version to get it on my card

[Rollo]

Interesting new development:

People selling Titans for $800-$900 losing $100+ in hopes getting the same performance with an OCd 780 and coming out $150 or so "ahead".

LOL-

"Aiiieeee! Must...not.....be...stuck...with...card that now looks overpriced!"

My Titan won't be the next card I replace, my 7970 will be, and only when AMD comes out with Hawaii.

[Zloyd]

Or they are doing this so they can get a 2nd 780 when the prices drop 50-100$ but ofc you cant see it that way.

And? eVGA did nothing to the Titan card except slap a sticker on it and put it in a eVGA box. If nvidia is allowing custom PCB's, why would eVGA not make a custom card?

[GoldenTiger]

Anyone know where to get nvflash v5.136, which is supposed to be the version needed to flash the 780?

They're coming out in the coming weeks.
