AMD announced the Vega 10 based GPUs today (on sale August 14). https://news.ycombinator.com/item?id=14889357 https://news.ycombinator.com/item?id=14889357 Apparently they are going to bundle most of them with games and hardware discounts initially, to discourage buy ups by the miners. http://www.anandtech.com/show/11680/radeon-rx-vega-unveiled-amd-announecs-499-rx-vega-64-399-rx-vega-56-launching-in-august/2 http://www.anandtech.com/show/11680/radeon-rx-vega-unveiled-... The RX Vega 56 part has 50% higher SP compute per watt than the RX 580 and 570 (50 SP GFLOP/watt), and is only $399 MSRP.

EDIT: I see these bundles are definitely to limit demand on the early cards. I expect they will keep miners at bay until they start having volume on the single cards. That's fine. Single Point calculations per watt or per second are not really the relevant measure for miners, it's all about memory bandwidth. We will see how these stack up.

  OK. Memory bandwidth for the Vega 56 part is 410GB/s, vs. 256 and 224 for the RX 580 and 570 respectively.
  - rothbardrand 9y ago
    Right, those are good numbers for the price, comparable to the 1080 Ti, so this bodes well for using them for mining... however we will have to see if there are any gotchas (the access patterns for mining are different than for games, so for instance GDDR5X was less effective than GDDR5 despite being theoretically faster.)
    - dbcooper 9y ago
      Was that due to increased latency?
      - rothbardrand 9y ago
        That would be my guess, that the bandwidth was very high but the latency was higher than the cheaper part, maybe not all the time, but in a way that affected this hashing algorithm.

        No, that because you upgraded to Windows 10.

  Well the results are already available since FE has been out for a while. It was pretty bad tbh but the price on these versions are better. the 100$ is not really enough to matter just an unclassy way to upsell. guess ill have loads of free hardware
