The fact it can only draw 300W within specs?

Since when has spec ever stopped us? Even if it did 50w additional headroom is nothing to scoff at.

Nvidia said that it was due to the size of GK104, the higher voltage on that size of package caused migration to deteriorate the life of the GPU at an accelerated rate. It wasn't necessarily the clock speeds that caused the problem. With GK110 being so much larger, almost 2x the size, apparently it will be able to take that extra voltage and not impact the life of the package....so we should see some pretty solid OC out of Titan.

That being based off the fact that Nvidia said it was the small GK104 size, and that Titan is so much larger and won't be voltage locked.

Yea....a 7970 at 1200Mhz draws about 315 watts full load, which is about 60 W over factory TDP. I can't imagine what Titan at ~1000Mhz and 300W would look like in performance.....

A beast I would imagine.

I've never heard of die size affecting electromigration - process size, but not die size.

The reason GK104, the 600 series, has voltage control is due to the architecture itself. If you over-volt the package you get migration, which damages the package and sends out in a blaze of glory. That is why it was voltage locked.

This is not the case with GK110, it can take the extra voltage without risk of migration and subsequent damage to the package.

the concept of electromigration is universal. it can affect AMD and Nvidia chips. All these chips are manufactured on the same process - TSMC 28nm high k process. So the effect of excessive voltage is similar on all these chips. It can and does affect the life of the chip. do you mean to say Titan can run at 1.3v while GTX 680 cannot. thats just not true. we have already seen GTX 680 lightning users with unlocked voltage push the GPU to 1.4+ Ghz on air. same for Tahiti users who can go upto 1.35 Ghz. I am willing to bet with watercooling titan can get close to 1.3 Ghz provided they have custom designs with beefier power delivery. dual 8 pin power connectors and more PWM phases.

Nvidia is providing voltage control because they are selling this at a crazy price as a super enthusiast product. They also have significantly better margins than GTX 680 on this product to support for RMAs due to excessive overvoltage and eventual death within warranty period as it would happen in few cases.

Well, even so, if this thing has a 200% Power Target, as opposed to the 670's/680's measly 132%, we may see some big overclocks.

I'm not saying that the 132% gets in the way of overclocks on 670s and 680s, I just mean that with Nvidia giving us that much room, it seems like they planned on people really overvolting/pushing these things.

I don't know man I'd imagine the margins on a GK104 being sold at $500 (and even now down at ~$440) are pretty freaking good for Nvidia.

Nvidia knows how to market and sell products. AMD should learn from them. biggrin.gif
this coming from you!? eh-smiley.gif seems like Nvidia really did hit a home run with this GPU lol
