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.
Here are the official specifications of the new AMD Radeon 300 Series GPUs that should start appearing on the market any moment now, as expected they are essentially re-branded 200 Series GPUs. The more disappointing thing however is that specification wise and even price wise they are the same as their 200 Series counterparts, aside from a bit higher clocks maybe and possibly a bit lower power usage achieved with some optimizations of the manufacturing process. The new 300 Series GPUs come with the same amount of Stream Processors, the same number of TMUs and ROPs, even with the same memory bus width… so essentially we are getting pretty much the same thing, but with a new name and as a new product. So the AMD Radeon R9 390X is essentially an 8 GB version of AMD Radeon R9 290X, the AMD Radeon R9 390 is AMD Radeon R9 290 with 8GB VRAM, the AMD Radeon R9 380 is essentially an AMD Radeon R9 285, the AMD Radeon R7 370 is AMD Radeon R7 265 and the AMD Radeon R7 360 is essentially an AMD Radeon R7 260. Disappointing? Well we are, because we expected to actually see some more improvements that could actually lead to increase in performance, other than what you can do by overclocking the older GPUs yourself. So do not expect to get much different hashrate from these “new” AMD Radeon 300 Series GPUs for crypto mining…
Then comes the AMD Radeon R9 Fury X, based on the new Fiji GPU with HBM Technology – the only actually new GPU coming from AMD this time. With it we are getting a new smaller, but powerful video card with 4096 Stream Processors and efficient and silent water cooling. What we expect from this new GPU from AMD is to offer crypto currency mining performance that is very close to that of the recently introduced Nvidia GeForce GTX 980 Ti, and the price also seems to be the same. However the integrated water cooling of the AMD Fury X cards that is more silent and more effective than traditional air cooling solutions is making it the ore attractive choice for GPU mining needs. Of course we need to see how the new GPU will actually perform, but as we’ve already said our expectations are for very similar performance to that of the GTX 980 Ti. So if you are looking for new high-end GPUs from AMD to use for building GPU-based crypto currency mining rigs, than the Fury X could be a good choice, unlike the “new” 300 Series that are actually nothing new.
