Yesterday we have posted some first impressions and initial results from AMD Radeon RX VEGA 64 with Ethash and Equihash and now it is time to get some more results. We ran a quick benchmark using the latest NiceHash Miner Legacy version 1.8.1.1 Pre-release 3. While the VEGA 64 may not perform outstanding for more memory intensive algorithms like the ones used by Ethereum (ETH) and Zcash (ZEC) it does perform very well in more GPU intensive algorithms. As expected dual-mining does work well and provides a nice bit of extra profit when compared to single Ethereum or Zcash only mining. As you can see however some of the miners included in the NiceHash Miner Legacy pack are having trouble working on the AMD Radeon RX VEGA 64 for the moment as not all of them apparently support properly the new GPU.

AMD’s new Radeon RX VEGA 64 GPU is now officially out in the wild and we have some first impressions from it to share regarding crypto mining. There were various pieces of information and rumors regarding the mining performance of the new AMD VEGA, but since we got out hands on one we are going to share what are the actual out of the box results that we got from it. The new HBM2 memory used in the AMD VEGA GPUs is probably the most interesting part in the new product line, but unfortunately out of the box it does not do great in memory intensive algorithms. Of course we all know from AMD’s Polaris range that with some tweaks and modifications extra performance will most likely be available to miners, but that could take some time.

Probably the most important performance that people what to know about is the hashrate for mining Ethereum (ETH) and other crypto coins based on the Ethash algorithm. Unfortunately the out of the box performance from Radeon RX VEGA 64 using the latest Claymore Dual Eth miner that comes with official support for Vega is just around 31-32 MHS. We’ve seen claims of much higher performance being theoretically possible, but we are yet to confirm if it is and if these claims are actually real or just speculation. The not so great thing is that this hashrate is achieved with pretty high power consumption and the higher the temperature of the GPU goes, the lower the performance drops and it is really easy for the air cooler VEGA 64 to get hot.

Here is the situation with Zcash (ZEC) mining using the new Radeon RX VEGA 64 GPU from AMD, just about 475-480 H/s. The not so great performance in these two more memory intensive algorithms, even with HBM2 memory is not what is the most concerning thing however. What we are more concerned with AMD’s new Radeon RX VEGA 64 GPUs is the fact that they are power hungry GPUs and quickly get hot, so cooling them properly for 24/7 mining might be a bit of a challenge, at least for the air cooled model. The amount of power used does not justify the level of performance we get for mining out of the box at this point…

You can say that the new Radeon RX VEGA 64 GPU out of the box at stock settings does manage to perform very similar in terms of performance to what a well overclocked Nvidia GTX 1070 can also deliver for ETH and ZEC mining. The AMD GPU however does it with significantly more power used when compared to what the Nvidia card requires to provide very similar performance for mining (double the power for the VEGA). As far as gaming goes, the Radeon RX VEGA 64 is apparently closer to GTX 1080 in terms of performance, but then again it still consumes more power than the Nvidia card.

What remains to be seen is what the initial availability is going to be and what the actual pricing of the new VEGA GPUs will be considering the fact that the demand from miners might not be that high, though you never know… with market prices of Polaris GPUs at the level they are available now the official recommended price of the VEGA 64 does seem unreasonably low, so expect higher initial prices for sure. On the other hand the Radeon RX VEGA 64 could also do better in more GPU intensive algorithms than it is doing for memory intensive ones. The option for dual mining with one memory-intensive and one GPU-intensive algorithm may also turn out to be pretty attractive alternative, even wiht the not so great performance in memory-intensive mining algorithms alone.

If you were surprised by yesterday’s announcement from Bitmain with their 15 GHS X11 ASIC miner, then the new X11 ASIC from Innosilicon will surprise you even more. The Innosilicon A5 DashMaster is claimed to be capable of delivering up to 30.2 GHS X11 hashrate with just 750W of power usage, that is double the performance with lower power usage compared to Antminer D3. Of course we’ve seen before Innosilicon pre-anounce specifications of ASIC miners that end up too much with the actual product not able to deliver what was initially offered, still even if they deliver slower hashrate and higher power usage than what is currently cited it could still be an interesting product. What is really important here is what the price will be as Bitmain did manage to offer a really sweet deal price wise for their 15 GHS X11 miner, no word on pricing for the A5 DashMaster yet though.

For the moment there are still not that much details about the A5 DashMaster ASIC, the information about it is published only on the copany’s Chinese version of the website, nothing on the English site yet. Innosilicon A5 DashMaster should start shipping in early September according to the information on the website, so you can expect that around September time the difficulty of DASH will be already sky high. Other manufacturers of X11 ASIC miners such as Baikal, iBelink and PinIdea are also working on new products or have recently launched such. Of course they are not with the performance of the latest announcements from BitMain and Innosilicon, but could still be interesting products. For example Baikal’s miners support multiple algorithms and not just X11 like most others do.

Update: The information about the new Innosilicon A5 DashMaster X11 ASIC has been published on the English website of Innosilicon as well and there is another interesting piece of information also available. It seems that the miner is capable of achieving about 38 GHS when overclocked with a power usage of about 1250W. The company is taking pre-orders with the shipping expected to start on September 20th and the miners will come with 6 months of warranty.
