If you struggle to make the decision concerning which GPU (GTX1070 or GTX1070 Ti) is the best when it comes down to mining, you need to remember that there is a number of factors to take into account.
- Power usage and the budget you have.
- The number of PCIe slots on your motherboard.
- Whether the GPUs you’re interested in are available and you can buy them.
- The cryptocurrency that you plan to mine.
Power usage and the budget you have
Let’s compare GTX1070 and GTX1070 Ti in terms of power usage and the price you’re expected to pay for them. The first question you need to answer is whether the power usage of the GPU you’re interested in is important for you. There is a couple of approaches people take advantage of when mining. The first approach is when a miner is up to mining as many crypto assets as possible within a short period of time. In this case, he/she doesn’t care about the power usage. Such a miner believes strongly that the price of the crypto currency he/she wants to mine will increase very soon. That’s why he/she is aimed at accumulating as many crypto assets as possible. If you fall under this category of miners, the only thing you should pay attention to when buying a GPU is the hash rate you can get with it.
At the same time, if you’re the one who is going to mine as business, you’re to get the card with which you can return your investment as fast as possible. The thing is that when a person mines as a business, he/she doesn’t sell out his/her crypto assets at once. It’s more profitable for him/her to sell them out on a weekly or monthly basis. If you’re one of such like miners, the power usage of a GPU is very important for you. Consequently, the 1070 Ti GPU (4 Sol/watt) will be more attractive for you than the 1070 GPU (3,5 Sol/watt).
Have a look at the comparison chart provided below. The chart allows us to compare the cheapest 1070 Ti GPU (ZOTAC 1070 Ti Mini) that’s currently available at the market and one of the mid-range 1070 mining GPUs (ASUS Rog Strix).
As you can see, the blue and green cost lines are almost parallel. This is due to the fact that the power usage of the GPUs is almost the same. The blue line shows the power usage of the ASUS 1070 Rog Strix with which you can hash 450 Sol/s while using 120 watts. The green line shows the power usage of the ZOTAC 1070 Ti Mini with which you can hash 488 Sol/s while using 125 watts. It seems obvious that you’re to get the ZOTAC 1070 Ti Mini GPU especially considering the fact that it’ll allow you to save some money when mining. In particular, we are talking about the fact that you’ll have to pay a bit less per 100 Sols when you mine with ZOTAC Mini ($184 vs $196 with ASUS 1070 Rog Strix).
Comparing GPUs before making the final decision is very important. Currently, the prices you’re expected to pay for these GPUs are almost the same. However, in case the price of the card you’re interested in increases, it can affect your decision.
There is one more thing we shouldn’t forget. In case you live in a place where electricity is very expensive, your aim will be to find the most efficient GPU and then tune it so that it uses as little power as possible. However, if you’re lucky to live in a place where electricity doesn’t cost much, you’ll be interested in tuning the GPU you buy so that you have max hash rate with it. Actually, there are GTX1070 mining GPUs with which you can get the same hash rates as when mining with GTX1070 Ti (Equihash algorithm). If you’re the one who wants to mine Ethereum (or any other Ethash crypto assets), the hashrate you’re to expect with both the GPUs is approximately 30-32 MH/s.
The number of PCIe slots on your motherboard
You may wonder why it’s so important to take into account the number of PCIe slots on your motherboard when choosing a GPU. If you’ve already built a mining rig and you’ve only one slot available, your aim is to get the fastest GPU you can buy. Everything is simple here. 1070 Ti has a higher hash rate then the 1070 GPU. If you have enough money, you can have a look at the 1080 GPU (it hashes faster than the 1070 Ti GPU). The 1080 Ti is the fastest of them all (but its cost is considerably higher as well).
In case you have more than 1 slot available on your motherboard or you’re currently building a new mining rig (and have a new motherboard with 6-7 slots available), the hash rate of a GPU doesn’t really matter to you. You need to find the GPU that’ll allow you to get the money you invested back as fast as possible. In other words, you need to look for a GPU that hashes rather fast but has a rather low cost per Sol.
Since the prices on mining GPUs can be quite crazy at times, you need to check the comparison charts before deciding which card to buy. As a rule, the GTX1070 Ti GPU is cheaper per MH or Sols than the GTX1070. With GTX1070 you’ll have to pay $1.90 – $2.25 per Sol/s meanwhile with GTX1070 Ti you’ll have to pay approximately $0.30 per Sol. For instance, if you have the ZOTAC 1070 Ti Mini, you’ll have to pay $1.25 per Sol.
The more Sol/s your mining GPU can do, the more crypto assets you’ll be able to get. Consequently, the less you have to pay per Sol/s, the faster you’ll manage to get the money you invested in your rig back. That’s actually why there’re many miners out there who prefer buying 1050 Ti GPU. It’s not that much energy efficient. However, the thing that makes the graphic card worth paying attention to is that the cost per Sol is below $1.00. This is the card with which you’ll be able to get the money invested in 2 or 3 months. make sure that you have enough money to buy 6-7 1050 Ti cards so that to have a high hash rate.
Whether the GPUs you’re interested in are available and you can buy them
There are lots of miners out there who are crazy about getting this or that GPU. The fact is that you may have hard time trying to get the GPU you’re interested in because it may be sold out. This is the situation the majority of miners face with when looking for 1060 or 1070 GPUs. In fact, it so happens that miners have to buy 1050 Ti or even 970 GPUs because they don’t want to wait for the card they chose before to be delivered. They want to start mining as fast as possible.
If you don’t want to wait for your GPU for 2-3 months, have a look at the graphic cards that’re currently in stock. Of course, their performance may be way worse than the performance of the GPU you wanted to get before. Still, the crux of the matter is that these are the cards that you can easily get and start mining today!
The cryptocurrency that you plan to mine
It’s not a secret that different crypto assets have different algorithms that, in turn, have different needs. You should remember about these needs when buying a new GPU. For instance, if it’s about Ethash algorithm, keep in mind that it depends on memory speed. However, if you’re the one interested in such crypto assets as ZCoin, Bitcoin, etc. (that run on Equihash algorithm), don’t forget that this algorithm depends a lot on the GPU’s core clock speed.
Actually, when mining the crypto assets that run on Ethash algorithm, the max hash rate you can get with GTX1070 is almost the same as the one you get with GTX1070 Ti (even though it’s more expensive). GTX1070 Ti seems to be a great option if you’re interested in mining cryptocurrency that runs on the Equihash algorithm (You’ll get higher hash rate than with the GTX1070).
