AMD gambled on HBM2 and it paid off in ways they never expected. They were simply getting dominated by Nvidia and threw a hail mary pass on memory bandwidth and speed, knowing they couldn't compete on compute loads.
Enter the CryptoNight and Dagger-Hashimoto algorithms, and well, the rest is recent history for the RX architecture, primarily the Vega line.

- washadjeffmad 9y agoVega 64 has improved since launch, beating the GTX 1070 in efficiency this past Sept 2017 by achieving 0.20 mHash/W over the 1070's 0.18 mHash/W. They're still within 10%, so it's not a great margin unless you're very focused on density.
