Powerful, cool and loud: Zotac GeForce GTX 1070 Ti Amp! Extremes in the test

So, or something like that, the R&D department at Zotac must have thought when the new project was approached. But the fact that even then something can go wrong and pencil-tipping accountants hand over the rather worse designers, will be... Zotac bets on the Zotac GTX 1070 Ti Amp!

Overclocking

Whether it's the propagated 1-click overclocking via Zotac's software or a real manual overclocking with suitable tools- the limits of this card are identical to those of the competitors. With an adjustable Power Target of 140%, the card approved almost 230 watts and was already slowed down by the voltage. We were able to increase the GPU clock by 180 MHz and the memory clock by 150 MHz to achieve a stable result over a longer period of time.

Temperatures and clock rates

First, we compare the achieved start and end values for temperatures and GPU clock (boost) in tabular form:

	Initial	Final value
Open Benchtable
GPU Temperatures	29 °C	53 °C
GPU clock	1860 MHz	1784 MHz
Ambient temperature	22 °C	22 °C
Closed Case
GPU Temperatures	30 °C	57 °C
GPU clock	1974 MHz	1784 MHz
Air temperature in the housing	22°C	40°C
OC (Open Benchtable)
GPU temperatures (approx. 2530 rpm)	29 °C	47 °C
GPU clock	2101 MHz	2088 MHz
Ambient temperature	22°C	22°C

For better illustrations now again the respective courses considering our timeline of a total of 15 minutes each for the warm-up time.

Thermal analysis of the back of the board

Finally, we consider the thermal analysis of the respective load states.

Gaming and overclocking

We see that pretty much all areas stay pretty cool with the gaming loop, because the airflow is completely exaggerated. But we'll get there right away.

This also applies to the use in a closed housing, where we average around approx. three degrees higher temperatures.

If we overclock at most, but leave the fans to themselves and close the housing, this draught is sufficient at then approx. 228 watts power consumption completely to freeze everything down to the foundations.
