Temperatures, Clock Rates & Overclocking
The limits of this card are identical to competing boards with similar power ceilings. At a maxed-out target of 122%, we measured just under 215W. Voltage and (unfortunately) power were the identified limiting factors.
Our sample ran stably with a +200 MHz GPU and +150 MHz memory overclock.
Temperatures & Clock Frequencies
The following table includes starting and end values for our temperature and GPU Boost clock rates.
|Header Cell - Column 0||Start Value||End Value|
|Open Test Bench|
|GPU Frequency||1873 MHz||1784 MHz|
|GPU Frequency||1873 MHz||1759 MHz|
|OC (Open Test Bench)|
|GPU Temperature (~2530 RPM)||29°C||54°C|
|GPU Frequency||2101 MHz||2063 MHz|
Temperatures vs. Frequency
Here's a closer look at the data over 15 minutes, during our sample's warm-up phase.
IR Image Analysis Of The Board's Back
The airflow provided by Gigabyte's three-fan thermal solution is sufficient to keep its GeForce GTX 1070 Ti Gaming 8G relatively cool during our gaming loop. Apparently, the company is trying to keep GP104 below 70°C to avoid losing too many GPU Boost steps.
The same observations apply to our tests inside of a closed case, though we do see temperatures roughly three degree higher on average.
With maximum overclocking inside of a closed case, no changes to Gigabyte's fan curve, and a power consumption of ~215W, there's still enough airflow to keep the GPU below 75°C. The voltage converters stay at ~80°C and are thus at no risk of overheating, especially since those temperatures could drop another 3-4° with the backplate in place.
One measurement that really stands out, though, is the memory's lower-than-normal temperature. At this point, we're seeing the benefit of GeForce GTX 1070 Ti Gaming 8G's altered board layout, with GP104 rotated by 90°. Way to go, Gigabyte!
Even though our stress test shifts the thermal load toward the memory and its voltage regulation circuitry, the readings stay almost as cool as what we saw during the gaming benchmark.
Even in a closed case, temperatures don't increase by more than ~2°C at certain hot-spots. Also, don't forget that the backplate we removed for these infrared tests does improve cooling performance. Those readings should drop a little once we get it back into place.

I do not think it means what you think it means...
The Geforce 1080 beats the Vega64 in Tom Clancy's Ghost Recon Wildlands at 2560x1440.
The Vega64 is also a 295 watt tdp card versus the 180 watt Geforce 1080.
A 60% increase in TDP to be 0 - 12% better is not very efficient.
For completeness, the Geforce 1080 Ti is a 250 watt card.
On the other hand, Vega56/64 are both awesome monero miners even taking their 295 watt tdp into account.
If you don't have any problems, you can build your own... ;)
I wish you also a happy new year and have a nice time. :)
My uncle, Herr Professor, sent me German Erektor Sets for my earliest birthdays (or so I seem to remember), Your question brought to my mind a vision of an erector set tower held together by wire ties.:pt1cable: I guess it would be good for an earthquake, although I would not like to be on it at that time.
