Nvidia GeForce GTX 1080 Mining Spectacle Review
The GTX 1080 series were released by Nvidia past year spil an upgrade to the 980 series. Originally, those GPUs were meant to be used by gamers only, but the deficit of AMD mining GPUs made miners interested te the GTX 10x0xx series too. Ter this article I will dive spil deep spil possible into the possibilities those card offers for mining.
For those of you who are into Ethereum mining, I will embark this article by anticipating that the GTX 1080/1080Ti is not good for this crypto coin. Hashrate-wise it can be configured to throw big numbers, but power-wise it will remain inefficient, spil well spil the high cost of the card makes it have high ROI.
That being said, the GTX 1080/1080Ti can be employed for mining other algorithms, which is something I will review here. While no one will recommend you to purchase a GTX 1080/1080Ti for mining purposes only, you can profit from it if you already have one or two ter your gaming equipment.

Spil you could notice, the GTX 1080 series use GDDRX memory, which seems to be the fresh VRAM standard for Nvidia high-end cards. While on paper GDDR5X is quicker than its predecessor – the GDDR5 – it proved to perform worse for mining. Experts say that this is due to different clock timings and architectural nuances. Whatever is the case, it is certain that GPUs tooled with GDDR5X VRAM are not meant to be used for Ethereum. Some speculate that this kwestie could be immovable by modifying the BIOS, but no one could prove that yet.
Nvidia GTX 1080 Series Ethereum Hashrate
GTX 1080 Ti
On stock settings, the GTX 1080 Ti FE outputs 32.04 MH/s. This is a bit better than the GTX 1070 which starts at 26 MH/s and can be overclocked up to 31-32 MH/s. The tests were performed using Claymore’s Dual Ethereum GPU Miner 9.Four on Windows Ten v1703 (which is considered the best Windows Ten version for mining).
Now, wij can achieve up to 35 MH/s te Ethereum if wij overclock it (memory clock +300 MHz), 37 Mh/s memory clock +750. The power draw becomes about 10% more, so it goes arm by forearm with the increase of hashrate. It can be undervolted by lowering power limit to 80% / 85% either 75% depends on the GPU if it can treat it.
The GTX 1080 is about 40% slower, hashing only 20.35 Mh/s using the same setup. This means that it outperforms the GTX 980 eight times, with the 980 hashing only Two.95 MH/s. While that is a hefty improvement indeed, it is still far from the AMD line, with the RX 480 outputting 24.86 MH/s on stock settings.
180 – 216 W (stock – OC, respectively)
Wij can conclude that the GTX 1080 Ti does not have the same VRAM timing issues the 1080 has, therefore it performs notably better on Ethereum. However, the differences end there – most miners will still agree that either GPU is not profitable for ETH because of their elevated price and power consumption.
It is worth mentioning that Nicehash provides us with even lower hashrate. Another significant note is that the GTX 1080 might hash up to 23 MH/s if you run it on Linux rather than Windows Ten. Looks like Win Ten still got driver compatibility issues with fresh Nvidia cards, even however they are not spil bad spil they used to be a year ago.
GTX 1080 Series Non-ETH Hashrate
On stock settings, the 1080 Ti outputs 740 Sol’s with a power draw of 285 W. This can be further improved by reducing the power target by about 75% – 80%. While this will druppel the hashrate to about 600 Sol’s, the power draw will be diminished to 150 W, which will notably increase power/hashrate ratio. Depending on the price of ZCash and how much you pay vanaf KW of electrical play, underpowering your card might be the best solution.
Overclocking them might get you up to 775 Sol’s, but the power draw increase might not be worth it, depending on the cost of the coin, electro-therapy cost at your place and the card edition.
The 1080, on the other mitt, goes about 500 Sol’s on stock.
Thanks to Cryptomining blog, wij know how the GTX 1080 performs on other algorithms. By ‘overclocked’ wij mean Power Limit + 20%, , Memory Clock + 125 MHz and Core Clock + 240 MHz.
Once again, it is worth mentioning that overclocking is not always the way to go. Depending on your card manufacturer and batch, it will react differently to overclocking. However, thesis numbers can be considered a ge baseline – while overcocking and underpowering will certainly lead to better results, do not expect those to be better than 10-20% (the average spectacle boost is 12%).
Spil for today, I haven’t found any magical clock/power target setting that would make either the 1080 or the 1080Ti have notably higher hashrate or notably lower power draw. Obviously, there is difference inbetween OC and non-OC hashrate, but it is the same spil you would expect from any other GPU.
It is also worth mentioning that Neoscrypt spectacle went form 265 KH/s to 985 KH/s once the ccMiner 1.7.6-r10 came out.
The GTX 1080 series were around since June 2016. If you’re looking for reviews of the card on the web, it is significant to check the date of any review you find. Until some months ago, it wasgoed almost unlikely to run a GTX 1080 on Windows Ten for mining. People would get enormously low hashrates on their 1080’s, sometimes spil low spil 4-5 MH/s for Ethereum. This wasgoed partially solved by the latest Windows Ten updates, however.
Also, the elevated power draw of the GPUs makes the cards hot. No wonder why most 1080 editions come with two or even three ventilatoren. You might practice warmth issues if you install all your 1080/1080Ti together on one single MoBo. Ter order to avoid that, you might want to use risers. This will permit you to keep the cards chic from each other, thus making warmth dissipation more effective.
Eventually, the GTX 1080 Founders Edition has rather low TDP (+20% increase limit), with power consumption limit of 216W. It is expected for third-party GTX 1080s have somewhat higher TDP, however opinions differ.
Before to proceed further, please share this 🙂 thanks!
GTX 1080/1080 Ti Price
Price-wise, the GTX 1080 and 1080 Ti are rather expensive. They do outperform the 1070 and 1060 when it comes to gaming, but spil you already noticed, they don’t do indeed well when it comes to mining.
What numbers can wij expect?
The GTX 1080 Ti Reference Founders Edition hovers around the $ 700 price mark. For the same price, you can but the PNY variation which comes with higher overclocking potential than the FE.
Clock-wise (no pun intended), the FE features 1,480MHz and 1,582MHz base and boost clocks, respectively, while the PNY comes with 1,531MHz base clock and 1,645MHz boost clock. Those toegevoegd 63 MHz might actually notably affect hashrate.
Now, the situation with the GTX 1080 is a bit more complicated since most of those GPUs are already sold. Most shops will either tell you that they ran out of stock or suggest you the GPU for $ 800+. The only place where I found a GTX 1080 with its original price tag is Best Buy – they suggest you the Nvidia Founders Edition for $ 550.

If you’re assembling a equipment from zero, then I will recommend you to check other cheaper GPUs for that purpose. You can either attempt to get some GTX 1070s, or wait for Nvidia and AMD to release their mining GPUs. Whatever is the case, the 1080 series are only justified to be used for mining if you already have one on your gaming PC and want to make an toegevoegd buck with it.
Thank you for reading. Spil always, your comments, suggestions and questions are welcome.

Here ter Switzerland, you can find many 1080’s on the market due to the price. One 1080 can almost buy Two or Trio RX cards. Superb postbode.
Good article, I just read it a bit late :p
Anyway, using linux and tuning OC and power settings nicely, I managed to get 23Mh/s on ethereum using 100W with a gigabyte gtx 1080 oc 8g (windforce).
Still a far sob from the 1070’s nice hash rates, but fairly blessed with power consumption.
hmm, I have a GTX1060 6GB that does 24mh/s @ 78W, at the wall…,
