The Bitcoin Foundation(TBF) Founding Director Jon Matonis explains the $4.6m loss in 2014. Funds were drained by exorbitant monthly expenses, conferences and the falling price of bitcoin. Today the ex-VISA employee advises Bitcoin entrepreneurs on funding. The role of the organization that introduced lobbying to Bitcoin and attempted to meme-ify titles for Bitcoin developers remains ambiguous. Despite recent announcements purpotting a change in focus towards development, questions remain unanswered. Like, what happened to the 5800 bitcoin mentioned in their 2014 transparency documents? A lot of the funds that did not go towards funding core development actually went towards sponsoring annual conferences for the […]

There are many factors to consider when monitoring the value of something such as Bitcoin. There is a certain psychology of markets that must be understood before making too many predictions. One is that positivity breeds more positivity. When people are feeling good about Bitcoin, they place more buy orders for it. When they are feeling negative or less hopeful about Bitcoin, they place more sell orders. Either case can affect the price in a significant way. There are many, surprisingly in wider mainstream outlets, who have attributed the recent relatively small gains of the Bitcoin valuation to the crisis […]

Hours after Greece had officially defaulted on its bailout loan from the International Monetary Fund; Eurozone ministers were already discussing terms of a new bailout loan to keep the country afloat. Officials today will decide whether or not an emergency loan to Greece from the European Central Bank. The meeting where ECB ministers will decide as much is only the first of two meetings that are to happen this afternoon, the other being in regards to Greece's request for a new bailout amounting in nearly 30 billion Euros and lasting two years. Many expect a tidy end to a short-lived […]

The latest high-end GPU from AMD, namely the Radeon R9 Fury X, that has been just recently announced has managed to provide performance high enough to be equal to the competition in the form of the Nvidia GeForce GTX 980 Ti… at least hen we are talking about using video cards based on these GPUs for gaming. We already did some benchmarks to see how fast the GeForce GTX 980 Ti is for mining, so it is time to see if the Fury X will be able to compete with these results like it does for gaming. An interesting advantage that the Fiji GPUs used in the Fury X video cards is that they come with HBM memory and both the video memory and the GPU are water cooled. In theory this means that you get lower temperatures and silent operation and the Fury X does manage to provide that. One more thing that you would normally expect from a water cooled GPU is to have a lot of potential for overclock, but unfortunately this does not hold true for the Fury X or at least not with the first card out on the market at least. We barely managed to squeeze out just about 75 MHz extra from the GPU and there is no option to overclock the video memory for the moment.
So off to do some tests with some of the popular and more profitable algorithms for mining lately, we have used the latest sgminer along with some of the optimized forks available for different algorithms such as the one optimized for Quark and Qubit. Note that there are not yet specially optimized kernels for the Fury X or settings that work best, so we were trying to use ones that we are familiar with already from the 280 and 290 series from AMD. So some of these worked really well, while others not so well and the generally available OpenCL kernels did provide quite disappointing results actually…
AMD Radeon R9 Fury X Results:
– X11 default: 6.778 MHS
– X11 Wolf0 Mod: 8.123 MHS– X13 default: 5.614 MHS
– X13 Wolf0 Mod: 7.176 MHS– X15 default: 4.69 MHS
– X15 Wolf0 Mod: 6.335 MHS– Quark modified: 22.37 MHS
– Qubit modified: 21.15 MHS– Neoscrypt default: 147 KHS
– Lyra2RE default: 287 KHS
– Lyra2RE Pallas Mod: 450 KHS
As you can see the results are a bit disappointing at this point, everything apart from the Quark and Qubit performance using the modified 280X kernels where the performance is really good and similar to that achieved on the GTX 980 Ti. Other modified/optimized kernels such as the ones for the X algorithms from Wolf0 or the Pallas mod for Lyra2Re do increase the performance a bit, but it it still disappointingly low. In fact on some algorithms you can expect to get worse results with Fury X than with a 280X for example, so we need to find better settings and maybe get optimized kernels especially for Fury X in order for that card to be viable for crypto currency mining. The only thing it is good for at the moment is for mining coins using the Quark and Qubit algorithm with the modified kernels, but then again buying a GTX 980 Ti instead could be the wiser choice for generally better mining performance for any algorithm supported… at least for the moment.
