Could an Arionum miner be more optimized for Ryzen? Using SHA or so?

The great performer I have is a mobile i7 7500U. With 15W / 3 threads / 2 cores / 4 Mb L3 / 3.1 Ghz sustained speed it hashes as high as 8-9 H/s using Java Miner with AVX2. Truly amazing.

My Ryzen gives the aforementioned 15-16 H/s with 14 threads / 8 cores / 16 Mb L3 / 3.2 Ghz sustained speed. A little shallow compared with the tiny 2 core mobile i7 at around same clock frequencies.

Ryzen truly excels in Cryptonight / lite algos.

But something tells me it arionum mining could be more optimized for Ryzen.
