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! Extreme on the same board as with the Zotac GTX 1080 Amp! Extreme, but there are still two clearer differences. On the one hand, the PCB manufacturer has switched from PALWONN to Victory Giant, ... Important preliminary remark
We had already mentioned it at the beginning that almost exclusively the resulting boost clock rates of each GTX 1070 Ti determine the final performance and thus the so-called GPU lottery and not the manufacturer and model.... Power consumption at different loads
The power consumption in the gaming loop is pretty much exactly on the point that Zotac set as the power target with 180 watts in the BIOS. In the Torture loop, the power consumption even drops below this value. A... 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 14...cooling system and backplate
The total of 24 MOSFETS of the eight phases of the GPU supply lie under a passive cooler, which is to be cooled by the air flow from above. What went wrong with the GTX 1080 works amazingly here.
... Summary
Where should we start in order to remain objective and fair? If a product comes with a completely loveless fan control and already in idle the same fan speeds as with Furmark in the closed housing,...
Power consumption at different loads
The power consumption in the gaming loop is pretty much exactly on the point that Zotac set as the power target with 180 watts in the BIOS. In the Torture loop, the power consumption even drops below this value. Even with the maximum possible power target of 140% being exhausted, the card with just under 230 watts remained a frame and even fell below Nvidia's limit of 240 watts. The limit is therefore the voltage, not the power as such.
The corresponding voltages for both loops in the factory state are shown in the following diagram:
Compliance with the standard on the motherboard slot
With a maximum of 3.6 amps (Gaming OC), the card is far below what the PCI SIG sets with a maximum of 5 amps (66 watts) for the 12-volt rail on the motherboard slot.
