Geforce GTX 1080 Ti is the latest GPU in Nvidia’s premium segment. It also happens to be the most productive single-chip solution at the moment. In this post, we’re going to take a closer look at the productivity of this video card for mining cryptocurrencies.
Geforce GTX 1080 Ti is equipped with 11GB GDDR5X video memory. This can cause some performance issues for those of mining algorithms that are not optimized for a new type of video memory. However, a large number of stream processors in the GPU can eliminate this problem.
The TDP of GTX 1080 Ti-based video cards is rather high – 250W. However, it is possible to slow down the heating of the video cards by reducing the power limit and thus avoiding productivity losses.

GeForce GTX 1080 Ti GPU card was designed with default 100% TDP. In other words, the power limit amounted to 250W, although Founders Edition allows for a 20%, or another 300W, increase (with cooling taken into account). All tests were performed at default settings and at a 100% speed of fans.
We deployed ccMiner 2.0 RC2 program developed by tpruvot to calculate productivity, and kept all the settings that it supports at their default values.
As you can see in the performance table above, hashing power and power consumption for each algorithm were verified (provided that they were launched successfully). The energy consumption is based on the data received from the video card and based on its TDP limits, not on the actual system data (which is due to be seen further).
An algorithm that does not limit the TDP to 250W can turn out to be more productive, however, it poses some cooling risks. On the flip side, not approaching the TDP limit critically allows to significantly reduce the power consumption with only a small corresponding decrease in the hashing power. This is a more profitable option in the long run.
BMW algorithm left us with an error of default intensity at 21 which we lowered to 15 to fix the bug. However, this resulted in a very low hashing power. With Cryptonight, we got an error of default intensity settings at 10.75 but its subsequent decrease to 10.25 helped us to rectify the issue. The results are outlined in the table.
Likewise, Jackpot algorithm left us with an error of default intensity at 20. Again, lowering it turned out to be helpful. Similar results were achieved with Quark algorithm. We experienced issues with Wildkeccak algorithm since it requires a scratchpad file which we were missing.
This video card is the most expensive in this product range. However, it’s also the most productive one. Therefore, it’s the most profitable option. With it, you can mine twice as fast as with 1070 GTX. If you are hesitating between 1080 or 1080 Ti, the answer is pretty obvious! 1080 Ti produces approximately 700 sol, 1070 produces 420 sol and 1080produces 510-520 sol. The profit is minimal but the price is much higher.

We were able to run a quick test of the new GTX 1080 Ti and the results look promising. The test was run using NiceHash Miner and the most profitable mining algorithms as per the NiceHash stats. The miners used for the test can be found in brackets.
Unfortunately, NiceHash Miner does not offer all of the most powerful miners. That’s why we ran additional tests using Claymore’s ETH miner. This allowed us to get a stable hashrate of 31.8 Mh/s (DaggerHashimoto) at GPU’s stock settings. In addition, while using EWBF’s CUDA miner, we’ve got 625 H/s (Equihash).
Now the time has come to boost Geforce GTX 1080 Founders Edition and run all tests once again using various mining algorithms to determine whether GPU suits mining purposes and whether the growth of the hashrate amounts to significant figures.
Founders Edition is somewhat limited in terms of maximum power consumption of the chip. There is only one 8-pin connector for additional power supply on the board. By default, TDP of the video card is 180W. Driver settings enable you to further increase TDP by 20%. (The highest possible figure will amount to 216W.)
The new Nvidia GPU chips have excellent boosting capabilities, particularly if you’re not much bothered with the power consumption by the video card. High boosting potential can be achieved thanks to the modern 16 nm tech process in the production of new GPUs.
Unfortunately, to boost the new GPU chips to even larger extremes, you will have to wait for the release of non-reference video cards based on GTX 1080 and GTX 1070. These will use original and more efficient cooling systems as well as additional power connectors to maximize the TDP.
Without changing the voltage of the core and setting power limit to + 20%, we managed to boost the reference GeForce GTX 1080 Founders Edition video card to +240 MHZ (chip) and +125 MHZ (memory). At the same time, the video card was able to continuously mine cryptocurrencies with various algorithms 24/7.

As you can observe in the table above, boosting the new GPU allowed us to increase the hashrate by an average of 12%. The results look pretty good and boosting the GPU even higher would allow you to achieve even better results.
Performance issues with Lyra2RE and NeoScrypt algorithms persisted. However, as far as Dagger-Hashimoto (Ethereum) is concerned, a slight productivity growth was observed for a mining farm run by Windows 10. If you have set to mine Ethereum, we recommend using Linux.
