Due to titans pulling a bit more power and thus having a harder time on the stupid stock bios compared to the 780. When you remove the bios bottleneck both will be limited by the voltage which is the same.

They didn't OC the Titan memory at all while the 780 had +500.... as I said previously, that's huge for GK110.

So clearly to me i can see a real treat if you set up the sliders, titan and the gtx 780 will end up pretty close to one another. The key figure here is the dissipation ability of the cooler. With boost 2.0, Titan is limited by its temps and the temps limited by its cooler. The same cooler is on the 780. With the sliders up for temps and fan profiles (and/or volts), using the same cooler as titan they both should end up really close to one another. Real close. This is because although they start off with different core count and different speeds, they both will have identical heat dissipation capabilities. Since they are both kepler cores and all use about the same power, NO MATTER HOW YOU SLICE IT you will get about the same performance out of each watt. So if the top end is set the same, a 780 consuming 250watts will put out about the same calculations as a titan capped at 250watts unless there is are specific impending factors. These factors i think would be rare in feasible gaming workloads.

What i am saying is, i expect that they could perform very close when they are both pushed to the max. That the extra cores of titan will be matched by the consistently higher boost clocks of the 780. I expect this will be the case unless their is an artificial crippling for the max settings with the 780s overclocking using the new boost. So as an example, Nvidia would have to specifically handicap the 780 to max boost to a 240watt tdp and titan can burn 255watts (just as an example)-but see since boost2.0 is tied mainly to temps, this would be a very hard thing to imagine at all. Since its heavily based on temps, then it all becomes the coolers ability to dissipate heat on two cards that have almost identical performance per watt. They start out at different levels but should max boost to around the same. This i would think.

I think that's pretty accurate... perfect, no, but it'll probably be borne out.

Unless the etailer/retailer makes a mistake, you will not receive any game codes. This is straight from the Geforce product manager himself on our conference call - no games will come with the GTX 780.

Thank you, And this is exactly one of the things that bothered me. I know we are on OCN, and we can all flash, but these should not have been gimped by boost 2.0, as a matter of principle.

I've yet to see a proper review though. That quote only applies to stock BIOSes and stock coolers... Pushed to the max the power output doesn't really matter. Both cards will be limited by the voltage and not power.

That and the comparison you posted previously had no memory OC at all on the Titan while the 780 had 500+. Not really a fair comparison at all. In heaven/valley for example my Titan gains nearly 6% from OCing the memory alone.

lachen.gif oc memory is useless.
1-2fps to the max in games at Titan lachen.gif

The comparison as I said wasn't the best one, but I have seen one from a US site showing the same results basically with actual games instead of 3dmark as well. The posts I've read about the Titan say the memory oc doesn't particularly help much in games, either. I'm not quite as into the whole synthetic benchmarking scene, but other than as a curiosity it's not really important as it relates to gaming performance.

After the 670 P/E OC Triple Overvoltage shenanigans MSI is off my list.
time to do something about that 4.0GHz overclock...
time to pump up the voltage and 'man-up'..

How high do your 7970s go? if you have one that can top 1250Mhz i'm interested in a sale wink.gif
