I remember Cestballot updated the AMD miner, and months later, he did the same to the green team, but it didn't end up working.
Now the AMD guys are getting another update?
Quite the BS I smell....
Not so fast, the AMD (R9) implementation is just now catching up to NVidias (Maxwell) implementation for Niro mining in terms of Performance per Watt.
Wolf0 has done an amazing job optimizing/vectorizing the OpenCL kernel for AMD. Its well written, clean, and easy to follow: 62 MH/s on my R9 280X. If we use his code on NVidia with some minor tweaks, we should see some decent performance gains and retain the Performance per Watt crown. So in a way, he is also indirectly optimizing the code for NVidias Maxwell.
Thanks to Wolf0 and Viz.
