Time for another group of tests of the newly released GeForce GTX 1080 Ti Founders Edition video card by Nvidia. This time we have used the latest released of the ccMiner 2.0 RC2 fork by Tpruvot in order to test how all of the supported algorithms perform on the new GPU. Do note that not all of the supported crypto algorithms by this miner may be performing the fastest, so you should use the results as a reference if comparing results from 2.0 RC2 release only. We have managed to successfully test the hashrate on most of the supported algorithms by this miner, though we still did have trouble making some of them work, but that is to be expected with a new GPU release…

We have used ccMiner 2.0 RC2 by tpruvot in benchmark mode with all of the default settings for intensity on all algorithms supported by the miner. The GeForce GTX 1080 Ti GPU was running at the default 100% TDP or with other words a Power Limiter at 250W, though on the Founders Edition GPUs you can increase it by up to 20% all the way to 300W (mind the cooling though). The tests were performed on stock operating frequencies of the video card with the fan set at 100% in order to keep the GPU cool and prevent thermal throttling (dropping of the boost frequency) because of high temperature that might be reached with auto fans.

As you can see in the table with performance results above we have posted the hashrate and the power usage for each algorithm tested (if the test has successfully passed). The power usage values are the ones reported by the video card itself only and are based on its TDP limit, not the actual values measured at the wall (these will be higher). The algorithms pushing the 250W TDP limit might be able to benefit from a power limit increase, though you might want to be careful with that in terms of being able to properly cool down the card. On the other hand forcing the TDP limited down might bring significant power reduction with a little sacrifice in terms of hashrate thus giving you better performance per Watt than the stock settings.

With the BMW algorithm we got an error at the default intensity of 21, and we’ve had to decrease it down to 15 in order to make it work, resulting in very low hashrate. With Cryptonight we got an error at the default intensity of 10.75, but down to 10.25 it worked and you can see the result in the table. With the Jackpot algorithm we also got an error at the default intensity of 20, however lowering it did not seem to help at all and the same thing also applies to the Quark algorithm. With the Wildkeccak algorithm we had trouble making it work properly in benchmark mode due to the specifics of the algorithm needing a scratchpad file.

The GeForce GTX 1080 Ti is the latest addition in Nvidia’s lineup of high-end gaming GPUs, but here we are more interested in another aspect for using these video cards – crypto mining. Tomorrow, March 10th, the sales of the new Nvidia GeForce GTX 1080 Ti should start priced at $699 USD, though initially there will be only Founders Edition models only with availability of non-reference designs expected to start showing for sale in April. The GeForce GTX 1080 Ti is based on GDDR5X memory clocked at 11 GHz, so the memory timings might not be the best for memory-based crypto algorithms, but the serious number of CUDA cores is there to compensate in terms of performance. Do note that the TDP of the new cards is set at 250W, though we expect that you should be able to lower the Power Limit a bit and get a better results than at stock settings.

We have managed to do some quick testing of the new GTX 1080 Ti and the results do seem promising. Starting with the currently more profitable algorithms on NiceHash and benchmarking with their NiceHash Miner that uses various fast performing miners (the miner used is noted after the algorithm). Not all of the latest and highest performing miners may be included, so we also ran some additional tests using the Claymore ETH miner that managed to provide a stable hashrate of about 31.8 MHS with stock settings of the card as well as the latest EWBF CUDA miner that managed to squeeze a bit more at about 625 H/s from the GTX 1080 Ti.

You can use these numbers as a reference, including the expected daily profitability if selling the hashrate form a GTX 1080 Ti on NiceHash that their miner also reports. Hopefully we are going to be able to run some more benchmarks in the next couple of days and play around to see what the GPU is capable in terms of overclocking, though with the pretty high boost frequency and a TDP of 250W you should not be expecting a lot more at least from the Founders Edition version that is launching first. Do note that properly powering and cooling six of these GPUs in a mining rig is not going to be as easy as with GTX 1070 Founders Edition for example that consume much less power and are a much more popular choice by miners using Nvidia GPUs.

Do note that with the launch of the GTX 1080 Ti, Nvidia is also going to have a new pricing for the GeForce GTX 1080 Founders Edition and GeForce GTX 1080 partner boards that will get a bit more cheaper. There is no word on reducing the prices of the GTX 1070 as well however. Furthermore two new models with higher clocked video memory should be available soon, the GeForce GTX 1080 with 11 Gbps along with the already available 10 Gbps model as well as GeForce GTX 1060 9 Gbps along the already available 8 Gbps versions. The faster memory variants might be of interest especially for the miners that are into mining crypto currencies based on algorithms that are more memory dependent such as ZEC or ETH for example.

A couple of days ago Nvidia has introduced their new lineup of GTX 1050 and GTX 1050 Ti GPUs, entry level for gamers and the successor of the popular GTX 750 Ti and the more recent GTX 950. We got an MSI GeForce GTX 1050 Ti 4G OC video card to give it a quick test and see what Nvidia has to offer with their new GPUs in terms of performance in some of the most popular crypto mining algorithms. While the GTX 1050 Ti may not be the most powerful solution for mining, the interesting part here is the lower power consumption per board just like it was back when GTX 750 Ti was released. So while it may not be the best choice for more serious multi-GPU mining operations, it could still be a viable option for a lower power home mining rig with 6x GTX 1050 Ti for example.

The GeForce GTX 1050 and GTX 1050 Ti are originally intended to be used without external power and have a TDP limit of 75W (because of the PCI-E slot), though we expect that there will be some companies offering more serious models with external PCI-E power. Do note that if you plan on building 6x GTX 1050 Ti GPUs mining rig you will still need to use powered extenders in order to avoid the possibilty of damaging the motherboard as the power draw from these will be significant.

When we consider the fact that the new GPUs are based on 14nm production process (the first GPUs to go down from 16nm to 14nm for Nvidia) and apparently do have some nice headroom for overclocking. We have managed to get +195 MHz on the core and +150 MHz on the video memory with the default voltages and what was limiting us from going further was the power limiter as the card was hitting the TDP and could not boost the operating frequency that much. Still the maximum frequency of the GPU it managed to hit briefly was 1911 MHz, so with higher power limit and with better cooling such operating frequencies might be available for constant boost.

Here are the numbers, comparing the performance of GTX 750 Ti, GTX 950 and GTX 1050 Ti using the latest NiceHash Miner software to get the hashrates of various popular GPU mining algorithms at the moment. As you can see there is a really nice improvement in hashrate between GTX 750 Ti and GTX 1050 Ti, maybe with some decent overclock the new GPU could even get to double the performance in some algorithms. Nevertheless the improvement from GTX 750 Ti is good in terms of performance and while there is also decent improvement from what GTX 950 offers, it is not that significant really. The main reason for that is the fact that specifications wise the GTX 950 and GTX 1050 Ti look pretty similar, even though they are based on different architectures it is much like the older one is just a bit slowly clocked and has somewhat higher power usage. Still the GTX 950 is pretty much in between the GTX 750 Ti and GTX 1050 Ti in terms of hashrate in pretty much all algorithms apart from Cryptonight where the weird result is most likely due to the lack of optimizations.

In the end the new Nvidia GeForce GTX 1050 Ti is really a good improvement over the GTX 750 Ti in terms of mining performance, you could probably get the a bit higher mining performance from 4x GTX 1050 Ti as with 6x GTX 750 Ti, and the power usage will be lower. You could still build a good mining rig with decent hashrate using 6x GTX 1050 Ti GPUs and do with a 600W power supply just fine. Of course, as already mentioned it might not be the best choice for serious mining operations where GTX 1070 would perform much better in terms of performance, but for home miners it could still be a viable option… just like GTX 750 Ti did when it first came out.
