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! 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, ...

In the Torture loop, the power consumption even drops below this value. A...

So, or something like that, the R&D department at Zotac must have thought when the new project was approached. But we will see later that even then something can go wrong and pencil-tipping accountants give up the rather worse designers.

Since the actual performance of all board partner cards of the GeForce GTX 1070 Ti must be very similar for all manufacturers due to the fixed base and boost offset, the real results achieved depend rather on the actual achieved in practice. Boost cycle, and thus indirectly from the cooling and primarily also the quality of the respective chip.

Each test based on benchmark bars is therefore only a random snapshot of a single specimen. This is precisely why we have focused on the actual technical implementation of each model and have been able to document this very well with our equipment.

Within the necessary tolerance ranges, it is definitely NOT possible that the performance of a particular card could be preceded by all others. We have therefore no longer used a manufacturer's name for the benchmarks, because according to chip quality, any card from any manufacturer can tend to the lower or upper performance limit.

Unboxing, dimensions and connections

The accessories are not only limited to the usual three-handers such as DVD, manual and 8-pin adapters, but also includes a VGA stand due to the extremely high weight of the card. We will discuss the exact board and cooling design separately later. The most important features are first summarized in a table:

Exterior views

The radiator cover is made entirely of light metal, which is set off with applications in carbon optics (carbon on rough anthracite). The card, which weighs 1350 g, is a whopping 32.5 cm long (slot aperture to the end of the card), 12.5 cm high (upper edge motherboard slot to card top) and 5.3 cm deep (PCB + radiator structure).

This length is mainly due to the arrangement of the three fans, each with a rotor blade diameter of 8.7 cm and the upper cover – and it is not easy to place this overlong card in the housing.

The back of the board is covered by a one-piece, almost U-shell-like backplate. Although it does not perform any active cooling function, it does not hinder the cooling process due to openings and a sufficient distance. In addition, parts of the side cover are still part of this housing part.

This backplate also requires a further five millimetres of depth on the back, which could be important for multi-GPU systems. The card is not really suitable for use in SLI systems, where every millimetre more distance between the cards is important, because the stability suffers extremely in an operation without a backplate.

The top of the map is embossed with the central, brightly colored Zotac lettering in a recessed acrylic surface, the color and lighting effect of which can be controlled by the software. The two 8-pin PCIe power supply connectors sit 180° rotated at the end of the card. Despite the extreme dimensions, the design looks rather dense and compact, which can be pleasing.

The end of the map is completely closed, as the slats are vertically aligned anyway and no air flow towards the end of the map or Slot aperture goes.

The slot aperture offers a total of five outputs, of which a maximum of four can be operated together (multi-monitor setup). In addition to the dual-link DVI-D (no analog signal looped through!), there is an HDMI 2.0 output and three DisplayPort 1.4 ports on the back. The rest of the slot aperture has some openings for the air outlet, but they have no real function.


Since the ex-factory specifications must be the same for all GeForce GTX 1070 Ti, the following table applies equally to all cards:

Test system and measurement methods

The new test system and the methodology have already been described in great detail in the basic article "How We Test Graphics Cards" (English: "How We Test Graphics Cards") and therefore, for the sake of simplicity, we now only refer to this detailed Description. So if you want to read everything again, you are welcome to do so. However, we have improved CPU and cooling once again in order to largely exclude possible CPU bottle necks for this fast card.
