Since various turbo technologies are becoming ever more advanced, gaming performance depends more on whether or not the cooling is sufficient to sustain the higher clock speed. After all, if the card gets too hot after a few minutes of gaming and the clock speed is lowered, this will also decrease the performance. That is why we also do a throttling test, that shows the performance level after a period of gaming.
Our throttling test consists of looping F1 2015 seventeen times, which takes about half an hour. In the meantime, we monitor the clock speeds and temperatures every second of the way. Afterwards, we analyse the data to create the graphs you see below.
The Nvidia GeForce GTX 1080 Ti starts out at about the same level as the Titan X, but gains a lead of about five percent after a few minutes. Initially, the clock speeds are comparable. This may be why the Titan X performs better in most benchmarks: that is where the number of ROPs shows its influence, while a longer (and therefore more realistic) game session compensates for it with the higher clockspeeds of the GTX 1080 Ti. After about half an hour, the GTX 1080 Ti has a 81 MHz clockspeed advantage over the Titan X.
|Average||Titan X||GTX 1080 Ti||Difference|
|0-2 min||1758 MHz||1777 MHz||-1,1%|
|2-5 min||1680 MHz||1741 MHz||-3,5%|
|5-10 min||1659 MHz||1732 MHz||-4,2%|
|10-20 min||1654 MHz||1733 MHz||-4,6%|
|20-28 min||1652 MHz||1733 MHz||-4,6%|
We also looked at the temperature at which teh GTX 1080 Ti settles, and this turns out to be a little less than 85 degrees Celsius - the same as the Titan X.
