    Phoronix: Ethereum Ethminer Performance With Radeon & GeForce OpenCL - August 2017

    Here are my latest Ethereum Ethminer benchmarks for those interested in mining this cryptocurrency using OpenCL on AMD Radeon and NVIDIA GeForce GPUs...

    I find this a little confusing - I thought AMD cards were significantly better than Nvidia for Ethereum, but aside from the 290, none of the AMD cards really stand out as being a whole lot better than their Nvidia counterparts. Not that AMD is performing poorly in these tests, but not good enough to warrant being sold out.
    Perhaps the closed-source drivers or the Windows drivers are what miners are using? Maybe there's a regression with ROCm?

    Also, are the H/s per dollar based on current GPU values or their original MSRP?

    EDIT:
    Kind of makes me feel I should've attempted selling my 290. I probably could've got back what I paid for it.

      In article: "A Phoronix Test Suite module also provided the current performance-per-dollar for Ethereum GPU mining, but this is a bit of a mess considering the lack of availability currently for most Radeon Polaris graphics cards... Prices for both NVIDIA and AMD were based on selections at Amazon."

        In these older test, Michael used the AMDGPU-Pro's OpenCL instead of ROCm, where AMD is in better shape against Nvidia:

        Also, AMD said that they are looking into performance issues with ROCm and some specific workloads

          I assume Michael ran cards with their out-of-the-box clocks and standard BIOS? That's the only way these numbers make any kind of sense even when you factor in for the slower AMDGPU-PRO OpenCL. From what I've read actual miners tend go trough with plenty of tweaks including things like overclocking and tweaking the timings of the RAM along with, almost paradoxically, lowering the voltage and GPU clocks for better power efficiency as Eth mining is generally memory bound.

            1070 is faster than 1080 and consuming more power?

              It's due to the memory configuration or something like that why for some crypto mining the GTX 1070 does better.

                Of course.

                  ROCm is not optimized for mining yet

                  UPD: and the latest comment on this issue:
                  "I did not realize that --cl-... flags matter so much till now. When setting --cl-local-work 256 and --cl-global-work 8192 I did get around 21 Mh/s, which is same as AMDGPU-pro."

                    Interesting!! thanks for the article Michael. It's always good to have hard numbers, I was intrigued on RoCm, if it could beat standard amdgpu pro. I want to squeeze every inch of performance of my Ryzen box. So we can conclude rocm is not yet mining ready. It 's something to keep an eye for miners with multi-core ryzen cpu prices going down, if RocM can beat opencl in the upcoming months, it would be a good alternative, many miners will switch to ryzen IMHO.
