Two weeks ago we took a look at an amazing graphics card from NVIDIA, the Quadro P6000. If you noticed in that review, we had another high-end graphics card from ASUS in the graphs, the ROG STRIX GeForce GTX 1080. We picked this card up about six months ago and have been very happy with it. Our workstation uses two Xeon E5-2699 V3 processors which we also game on with a 4K display (3840×2160). Currently, the game that puts the most stress on our system is Star Citizen; the STRIX 1080 handled it with no issues with very smooth gameplay. Everything was running very good. Of course, with the introduction of the 1080Ti, we had to upgrade. Fast forward to about three to four weeks ago we saw the ASUS ROG STRIX GeForce GTX 1080 TI 11GB OC Edition making the rounds on different review sites and decided that we must have one. 

The STRIX Ti OC version was a hot selling card with limited stocks available and seemed to be out of stock everywhere. It did become available for about an hour at Newegg, and we grabbed one. Being very impressed with the STRIX 1080 we were very excited to run the TI OC version through our benchmarks.

We have to admit that the ASUS ROG STRIX GeForce GTX 1080 Ti 11GB OC Edition is one impressive card. It’s very large, thick and has a good solid feel to it. The size of the card has a length of 11.73 inches. Make sure your case can handle a card of this length. The next factor is how thick it is; it is a 2.5 slot card. Double check other PCIe devices you may want to install so that space is given for air-flow to cool the TI OC properly.

At the back end of the card, we find two 4-pin fan connectors operated through ASUS FanConnect II. Tuning options that allow you to adjust external fan speeds for efficient cooling. GPU Tweak II allows you to adjust the fans in three modes, Auto, Manual or User Defined. This is a great feature because in many systems the GPU is now (by far) the hottest single component. Being able to control chassis fans directly to cool the GPU area is important.

Now looking at the end of the card we see at the top, a DVI-compatible connector. At the bottom row left we have DMI port, HDMI port, and 2x DisplayPorts.

  • DVI Output: DVI-D
  • HDMI Output: HDMI 2.0
  • Display Port: 2x Regular DP
  • HDCP Support: Yes

Software

The driver DVD that comes with the kit is rather limited and only has a few options.

Clicking on the install button brings us to this screen. In fact, most options will direct you to the ASUS website for downloads.

We advise heading over to the ASUS website and downloading all drivers and software to a USB drive before installing the card in your system. The website will give you the latest software for your new card. The same goes for the latest NVIDIA drivers, at the time of testing were 381.65.

AURA

The AURA Utility is used to control the cards LEDS. For those that use a case with windows, this is a nifty utility to help show off your card.

ASUS GPU Tweak II

This utility is one we find useful and use every day. It allows simple to use presets that control performance of your TI OC. These are Silent, Game and OC modes. Also, there are full manual controls for overclocking.

The STRIX GTX 1080 Ti OC shows strong performance with this benchmark.

AIDA64 GPGPU

These benchmarks are designed to measure GPGPU computing performance via different OpenCL workloads.

Single-Precision FLOPS: Measures the classic MAD (Multiply-Addition) performance of the GPU, otherwise known as FLOPS (Floating-Point Operations Per Second), with single-precision (32-bit, “float”) floating-point data.

Double-Precision FLOPS: Measures the classic MAD (Multiply-Addition) performance of the GPU, otherwise known as FLOPS (Floating-Point Operations Per Second), with double-precision (64-bit, “double”) floating-point data.

The next set of benchmarks from AIDA64 are.

24-bit Integer IOPS: Measures the classic MAD (Multiply-Addition) performance of the GPU, otherwise known as IOPS (Integer Operations Per Second), with 24-bit integer (“int24”) data.  This special data type defined in OpenCL on the basis that many GPUs are capable of executing int24 operations via their floating-point units.

32-bit Integer IOPS: Measures the classic MAD (Multiply-Addition) performance of the GPU, otherwise known as IOPS (Integer Operations Per Second), with 32-bit integer (“int”) data.

64-bit Integer IOPS: Measures the classic MAD (Multiply-Addition) performance of the GPU, otherwise known as IOPS (Integer Operations Per Second), with 64-bit integer (“long”) data.  Most GPUs do not have dedicated execution resources for 64-bit integer operations, so instead, they emulate the 64-bit integer operations via existing 32-bit integer execution units.

And we are back to the STRIX GTX 1080 TI OC outperforming the other cards.

Zcash Mining Performance

We had a request to run Zcash on our system to see what performance numbers the STRIX GTX 1080 TI OC would generate.

ASUS ROG STRIX GeForce GTX 1080 TI OC Zcash
ASUS ROG STRIX GeForce GTX 1080 TI OC Zcash

Here we set the card to OC Mode and let it run. The STRIX GTX 1080 Ti OC pulled 267watts and generated 695 Sol/s. Very impressive.

Given the current valuation ($230 USD : 1 ZEC) that yields approximately $9/ day in Zcash mined with the breakeven at an insane $1.40kWh. Compare this to a GTX 1080 which can mine at around 500 Sol/s at 190W. That is almost a 40% improvement in mining speed and the GTX 1080 Ti is currently profitable to mine with on all but the most expensive power.

Power Tests

For our power testing needs, we use a Yokogawa WT310 power meter which can feed its data through a USB cable to another machine where we can capture the test results. We then use AIDA64 Stress test to load the system and measure max power loads.

ASUS ROG STRIX GeForce GTX 1080 TI OC Power Test
ASUS ROG STRIX GeForce GTX 1080 TI OC Power Test

For our tests, we use AIDA64 Stress test which allows us to stress all aspects of the system. For this test, we selected all parts of the system to be stress tested, except for the OS SSD. The results show max power use from the wall. The max power draw we saw was 543.44watts under max loads.

Conclusion

Making plans to get a new graphics card is always a problem for us, when they are released there are many cards to look at from different manufacturers. Each manufacturer comes up with different cooling setups and GPU speeds. At the time when we first got our ASUS ROG STRIX GeForce GTX 1080 we were very happy with it. Gaming on a 4K (3840×2160) screen is very stressful on GPU’s, and when we do game we like to play with maxed out details and settings, the ASUS ROG STRIX GeForce GTX 1080 handled this with ease.

Then about six months later the Ti version of the GeForce GTX 1080 Ti came out, and we knew just the one we wanted to get, the ASUS ROG STRIX GeForce GTX 1080 Ti 11GB OC Edition. Was this new card worth the wait? Yes, it was. It chews through benchmarks and games with ease. It is truly an amazing graphics card. In many cases, it outperforms the Quadro P6000. If you do not need certified drivers for your applications, then look at the GeForce GTX 1080 Ti series of GPU’s. The day of the Ti is back.

ASUS has done a wonderful job with this graphics card; the card is amazing to hold in your hands, quality is top notch. The software used with this card, GPU Tweak II, makes switching OC settings a breeze. If you like LED’s on your cards, the AURA software will not disappoint you.

It’s hard for us to comment on noise levels, our office has a lot of machines running. We could not hear the card spool up under heavy loads. The difference in power draw between the different OC settings is minimal at best.

If you are into Zcash Mining, the ASUS ROG STRIX GeForce GTX 1080 TI 11GB OC Edition performed very well and can pay itself back in 4 months. You can check out our guide here.

When we look at how this card performs with our needs, workstation, and gaming, we do not feel getting a second card for SLI would be needed, one card handles everything we throw at it without issues.
