780 Ti user experience

[toyota]

pretty much all Kepler cards run well above what there advertised boost is.

 

[Spidre]

Which model did you get lava?

 

[lavaheadache]

EVGA reference

Indeed, I noticed this as well. And doesn't require a ridiculously high fan speed to boot.

780ti has some extra power delivery circuitry on the PCB.

It has not and if not throttled the card temp close
to the VRMs is 96.2°C.

They do have extra power circuitry. It is called "Power Balancing". That isn't to say it doesn't throttle, only that they have extra circuitry to balanced the power load.

http://www.overclockersclub.com/reviews/nvidia_gtx780ti/

With this card NVIDIA introduces a new power management strategy called Power Balancing to ensure no single supply source is overloaded. By load balancing the power source the expectation is a higher maximum overclock — something realized in my testing.

Further explained here:

The final improvement that we’ve added to the GeForce GTX 780 Ti is a new power balancing feature that’s been made so enthusiasts can get the most out of their overclock. As you know, the GPU gets its power from three sources: the 6-pin and 8-pin power connectors, and the PCI Express interface. Under normal conditions, the power sent to the GPU is balanced across these three sources, but when a user overclocks their graphics card they can unbalance the power delivery and draw more power from one source than the others, potentially maxing it out. With this new feature we can steer power from one input to another, so if you max out one power source, you can draw more power from the others to make up the difference. When overclocking, users should be able to push the GeForce GTX 780 Ti even further than they have with prior GeForce GTX TITAN/GTX 780 GPUs thanks to this feature.

For me thoses explanations do not make sense at all ,
it s not like the usual rail cant output 500W if needed
for an overclocked card.

Why suddenly pumping power from secondary rails
whould be more efficient.?.

Besides the rails provided by the PCIe connectors have much higher serial resistance , i would even add that it s not cautious to try to drain high current through the MB electrical tracks , this sound to me as a necessity due to a limited GPU usual power supply rather than an actual feature.

It may be necessary for high OCing, but it is a feature, or a necessity that has never existed before.

Could you run regular FireStrike and post a results link? I'd like to compare my results to yours.

Mine with SLI turned off (single card): http://www.3dmark.com/fs/1123661

SLI on: http://www.3dmark.com/fs/1123496

[BallaTheFeared]

Wut?

That's over 20% higher on the gpu score isn't it?

You guys both at stock/reference cooling?

 

[MrK6]

Very impressive results! Sounds like you got a really good chip. I might have missed it, but any plans for alternative cooling or are you sticking to reference?

 

[skipsneeky2]

Yup, out of the box my Zotac 770 is supposed to boost to 1098 but mine boosts to 1150 without touching a single thing at all which i think is fantastic and temperatures on load stay usually around a max of 75cel.

 

[lavaheadache]

yup, still on reference cooling and plan on sticking with it.

I have 2 reference 780's that I'll be looking to move soon if anybody is interested

 

[tg2708]

Itching to get the 780 but I think I can hold out awhile longer because the verdict has not been decided on the 290/x. At least their is no aftermarket cards for amd that will make deciding which to go with easier. And then again at the resolution I play at I still think their is no need for such cards but the price is right especially that 290. Main draw to nvidia is phys x, weird but true because I love the extra eye candy.

That is decent for stock performance. My 780 overclocked is not much faster

[Nintendesert]

Threads like this make me want to unload my 680 and get a Ti. I need to force myself to wait until there are games that actually need it for me.

Which aftermarket cooler is the best bang for your buck for a 780? Will they work with the ti, pictures looked like a slightly different PCB.

^A 290X overclocked is not much faster than his 780

Crap that's a fast graphics score. Wish Futuremark told you how high the GPU overclock was.

 

[BallaTheFeared]

Says 1,335 MHz Core, 1,740 MHz mem.

13235 is the best you can get from your classified on water?

A suicide run. Doubt those clocks are actually playable.

That's about as good as it gets on water for a 780. You can get a few more hundred on that if you have one of the golden 780s that can clock to 1500 on 1.35V, or use an EVBOT to run an insane 1.5V+ through it to brute force it there, but anything significantly higher is done on LN2.

That score is a 1409/3600 clocked 780. It's not entirely game stable, I have to do 1359/7200 to pass any game.

 

[lavaheadache]

Sorry guys I wasn't clear. That 3dmark run was with a +200 core.

This one is +200 core and +300 mem

http://www.3dmark.com/3dm/1603043?

 

[BallaTheFeared]

You gained hardly anything with the +300 mem.

 

[lavaheadache]

You gained hardly anything with the +300 mem.

memory speed probably isn't a bottleneck in 3dmark.
