Asus ROG Strix GeForce GTX 1080 Ti OC in review

The two 8-pin sockets for the external power supply are followed by two coils in the input area for smoothing the tips. Asus relies on a design of 5+2 phases, with the 5 phases for the GPU being designed.

Asus uses the same board as the ROG Poseidon Platinum hybrid card, but with slight modifications to capacitor assembly.

Otherwise, the Strix cooler of course has much more space, which can only be advantageous. The map follows the Strix line purely visually, even though some minor cosmetic surgeries have been performed.

DirectCU was yesterday and we present in advance the scheme of the Aus-PR, which should explain the map and its structure in detail. We will of course go into all areas in more detail and with our own measurements:

Since the actual performance of all board partner cards depends more on the actual boost clock achieved, and thus causally depends on the cooling, the power target and above all the quality of the respective chip, any test based only on benchmark bars is more of 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.

Unboxing, dimensions and connections

The accessories are limited to the usual three-handers such as DVD, manual and 8-pin adapters. Otherwise, there is only the card. We will discuss their exact board and cooling design separately later. The most important features are first summarized in a table:

Overview of installation dimensions, features and connections
Installation length:
30.0 cm (slot aperture to end cover)
Installation height:
12.5 cm (upper edge slot to top card)
Depth:
4.8 cm (2.5 slot)
0.5 cm baking plate
Weight:
1263 grams
Backplate: Yes, without passive cooling function
Cooling: Air
Horizontally aligned cooling fins
Fan:
3x 9 cm (8.5 cm rotor diameter)
Connections Slot blend:
3x DisplayPort 1.4
3x HDMI 2.0
1x Dual-Link DVI-I
Other shots:
2x SLI Connector
Power supply:
2x 8-pin PCI-Express

Exterior views

Let's start by looking at the map from the outside. Asus, like many others, is back on a matte, graphite-coloured plastic cover that is haptic and visually fine, but does not rip off the stool. Color applications outside the RGB light effects are searched in vain.

The backplate is purely for the look and carries an RGB backlit ROG logo. The two 8-pin sockets of the external power supply are installed rotated by 180°. The logo on the top is also equipped with an RGB backlight and can of course also be customized by means of its own software.

The cooling fins are vertically aligned, which pushes the exhaust air undirected against the top of the motherboard and the front panel of the case.

In addition to the two DisplayPort jacks, the connectors are based on two HDMI outputs, which is e.g. VR glasses, of course. The Dual-Link DVI connector is a nice, but now hardly necessary entry.

Specifications

The GPU-Z screenshot shows us the most important key data in advance, whereby the actual boost achieved was of course higher with our model. This in turn relativizes such theoretical data a little, so that we really want to refer to the following test results later:

Finally, the whole thing again as a tabular comparison to the other relevant graphics card models:

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.
