Normal gpu boost will NOT put another 190 Mhz onto the base boost clock for any card not even a Lightning.

Techpowerup added 87 Mhz to the base clock of the Lightning to get it to 1518 Mhz overclock.

Bit-tech, Guru3d, ReviewStudio and Kitguru among others also reviewed the Lightning card and they were all in the high 1300 to low 1400 for out of the box boost block.

And yes, 1400 mhz is indeed a safe average overclock for a 980 Ti. Most can easily get another 75-100 Mhz sometimes more.

Maxwell overclocks well, but no need to exaggerate it to the moon.

Yes they are, I cannot wait for the 1st high end card to come out. 4K is too much for my fury...

If you really think that à 980TI Lightning can do 1493MHz boost out of the box and 1518MHz only by adding a +87MHz base clock, you need to read reviews again and understand why it's impossible.
On the other hand, nVidia will certainly not allow such a thing. Thats why, most of the time, top end 980Ti cards are around 1400MHz boosting by default, already an impressive number though, with kinda tremendous performance.

You haven't explained how GPU Boost 2.0 works, either. Why don't you do that first.

I concede your point simply because you did state max boost clock when you said it. But what is the point of talking "max" boost clock when it's not the boost clock the card is running at when it's actually being tested? If we're going to talk about how cards perform, actual in game frequency or sustained boost clock is the realistic measurement. That 1493 MHz figure, you aren't going to game at that frequency. Once the card gets warm, gpu boost 2.0 is going to pull voltage and clock speeds down based on the temperature of the card.

Just who the hell are you to dictate my purchase decisions with my HARD EARNED MONEY? mad.gif

I don't speak for everyone here but I've owned enough Radeons and Geforces in my lifetime and I know very well that in my case, I've simply had better overall user experience with Geforce cards which has led me to prefer them. Simple as that.

Because that's what TPU give here in their max. boost clock after OCing their 980Ti samples to the max. I'll give you the same advice I gave to the above poster, read the TPU reviews before replying to me.

Five of 980Ti samples when overclocked to the max don't even have a max gpu clock that reaches 980Ti lightning's max boost at stock.

Almost 13,000 980 Ti samples submitted.

1390 MHz average overclock on air.

1496 MHz average overclock on water.

Selection bias is what you should look up before using hwbot.

It'd be impressive if those numbers are not boost clocks but I don't think it's even capturing the clocks correctly considering how the memory clocks fluctuates between different types of cooling. Nevermind that these are based on one off benchmark runs.

The 980 Ti Lightning is not the fastest 980 Ti Techpowerup has tested.

The Gigabyte Waterforce is the fastest 980 Ti they tested. It and the Lightning were tied at 1080p and 1440p. At 4K, the Waterforce is 26.5% faster than a stock 980 Ti and the Lightning is 25% faster than a stock Ti.

This is why the 1493 MHz "max" boost clock you keep going on about is completely useless in figuring how fast the card really is simply because it does not run anywhere near that speed once warm. The Gigabyte card has a max boost of 1430 Mhz yet it puts up the same or better numbers than the Lightning including the numbers when overclocked in the TPU test.

To be fair to the Lightning, the reason why it's slightly slower than the Giga card is because the Giga is running on water 15c lower and as such the Giga holds it's max boost clock longer.

It's not hard to figure out why the memory figures are off. A tiny little bit of homework looking at couple pages of results quickly resolves it. Some people submit the actual memory clock as their results, others are giving the effective memory clock. One person puts in 2000 MHz and another puts 8000 Mhz. Looking at the clock speeds, they report that both ways as well. Which means the boost clock they report using the screen in GPU-Z actually boosts higher in reality meaning the 980 Ti average is actually higher than 1390 MHz.

So for some reason you don't accept that the 980 Ti average OC from HWbot with 12,000 submissions is 1390 Mhz. Yet, the source you took all your other data from in this debate, TPU, has 9 samples with a 1483 MHz average OC. Can't wait to hear why TPU is wrong in that instance yet all the other data is valid to present.

Okay man, continue to believe that 980L is bosting 1493MHz out of the box and don't look at others 980Ti behavior instead like mcg75 is showing to you. Maybe, one day, you will understand.
And yes, Maxwell is a real overclocker dream compared to Fiji that got difficulties running past 1100MHz.
This Nitro design will maybe permit to gain 20-30MHz better OC but it's still a joke compared to the sky-rocketted OC from Maxwell.
Comparing Fury Nitro OC to an ultra conservative 980Ti at stock, it's like comparing a 980 OC to the hell versus a 980Ti vanilla. You'll see that 980 OC is really not so far on 1080p and 1440p. But, once you put the foot on the 980 Ti accelerator, it's not the same song at all wink.gif
