All About BItcoin and Litecoin mining and other alternative crypto currencies
Nvidia has just introduced their new high-end Maxwell-based GPUs the GTX 980 and GTX 970 and the expectations from them in terms of performance for crypto mining are pretty high. After earlier this year we saw what the mid-range GTX 750 Ti, the first Maxwell card was capable of, we already had high hopes for the upcoming faster models. Apparently we are not going to be disappointed by the performance we are going to get, below you can see a chart with the hashrate that the new GeForce GTX 980 (GM204) provides in various crypto algorithms. These were actual tests ran using the latest versions of CudaMiner and ccMiner with support for Compute 5.0 with no special optimizations that could possibly benefit the new cards any further.
In the table you can see the algorithm, the hashrate you get with the GTX 980 and the TDP usage percentage. The GeForce GTX 980 has a TDP rating of just 165 Watts, so with this maximum power consumption you can see that not all algorithms are utilizing it at 100%, meaning the actual power usage is lower. The performance you can expect to get from the GTX 980 is roughly about three times higher with about three times more power usage as compared to the GTX 750 for crypto mining. The initial price of the GTX 980 however could be a reason for miners to go to the slightly slower GTX 970 model for crypto mining as you should be able to get two GTX 970s for a price a bit higher than for a single GTX 980 and the performance you will get from the two cards should be significantly better than from a single GTX 980.
The results posted above are with a reference GTX 980 card running at stock frequency, considering that the GM204 does overclock really good, higher results can be attained when the card is overclocked. The second set of results (the OC ones) are achieved with the card overclocked to GPU at 1520 MHz, Video RAM to 8250 MHz and TDP limiter set to the maximum 125%. This is really pushing the GTX 980 to its stable maximum limits as the card really does handle serious overclock pretty well. Unfortunately we do not have access to a GTX 970 GPU for the moment, so we cannot yet test to see the difference in performance, though it should not be that high, but the 970 should be available at a much more attractive price, so it could be the more obvious choice for crypto mining rigs. The GTX 750 Ti still seems like a good more budget oriented solution for mining.
You should be well aware of the fact that some ccMiner forks are nor working very well with the GTX 980, we’ve had some weird results showing like way too little load and low hashrate or the miner crashing, also one of the reasons that not all available algorithms are listed. The GTX 980 and GTX 970 does support Compute 5.2 and not all forks of ccMiner we have used for testing are compiled to even support the Compute 5.0, the CudaMiner has not been updated for a while and we have used the latest official release for the Scrypt testing… not that you would use a GPU nowadays to mine Scrypt crypto coins anyway.
Bitmain has just posted a teaser about an upcoming product in the form of a Bitcoin ASIC miner – AntMiner S4. The new miner is supposed to offer 2 THS hashrate, but no other specifications or price is yet revealed. The tester does say however that the new miner should be available for order by the end of the week and it should start shipping to customers by the end of September. So it seems that the company is returning back to their previous way of doing business – announcing new miner and starting to ship it soon after orders are accepted and paid. Unlike with their recent announcement of a pre-order Scrypt ASIC miner – Bitmain Antminer L1 that did get not so positive feedback from users that are not happy with pre-orders that they have to wait for months.
We have already mentioned the recently lowered prices and lifetime contracts of Genesis Mining a few days ago. Now we can also take a look at what you can expect to earn if you purchase a cloud mining contract based on actual hashrate at the service and what it is earning on a daily basis. Starting with Bitcoin cloud mining and 10 THS hashrate that can currently earn you $80-$90 USD per day, that is if you are ready to pay $9790 USD price for the contract.
BTC earnings per day for 10 THS SHA256:
14.09.2014 – 0.18290000 BTC
13.09.2014 – 0.20100000 BTC
12.09.2014 – 0.21401850 BTC
11.09.2014 – 0.16451335 BTC
Here is how the situation looks like if you decide to purchase 100 MHS worth of Scrypt mining hashrate and want to be paid in Bitcoins. What you will get is about $20-$25 USD per day in terms of earnings based on the current exchange rate for BTC. At the moment the price of 100 MHS Scrypt cloud mining hashrate is $1499 USD. It is interesting to note that the ROI of Scrypt cloud mining is currently faster in the current market situation, however Scrypt mining is also a bit harder to predict and riskier. If you invest the same amount of cash in Scrypt mining hashrate at the moment as you would need for the 10 THS SHA-256D cloud mining contract in short term you can expect to get about $130-$160 USD per day, or close to double that of the same investment in Bitcoin cloud mining. The only problem is that in just a few weeks time the profitability of Scrypt might not be as good as it is at the moment as compared to Bitcoin.
BTC earnings per day for 100 MHS Scrypt:
14.09.2014 – 0.04798480 BTC
13.09.2014 – 0.05282940 BTC
12.09.2014 – 0.04697350 BTC
11.09.2014 – 0.04349110 BTC
So if you decide to invest in Genesis Mining in either Scrypt or SHA-256D cloud mining contracts make sure that you do the math using also the above numbers of actual earnings that you can currently expect to get. Do note that the numbers cited above are with the fees already deducted, so they reflect the actual amount of coins that you will receive on a daily basis as earnings. If you have already decided to get some cloud mining hashrate we have a bonus for you, a promo code – “CryptoMiningBlog5” that will give you an extra 5% discount on every purchase, valid for both Scrypt and SHA-256 cloud mining hashrate at Genesis Mining.
