Which one of those is the best to download and what are the differences?
The short answer -- the one that fits what your hardware can use.
Most AMD hardware has at least AVX support; some, AVX2.
Most recent Intel Hardware has AVX2 support; some has AVX512f -- use it if yours does.
Check with your CPU manufacturer (Intel Ark for instance shows all hardware features for each Intel CPU) to see which extensions you can use.
All hardware should be able to run the generic. Some older hardware with AVX support might run faster using "generic" -- the plain arionum-miner-java.exe which is for any Windows system.
Please note that there is a hard requirement for 64bit JRE for all versions.
As to what is better -- AVX is a kind of vector operation extension. AVX2 doubles the size of the vectors useable. AVX512f as used in this lib, doubles the size of the vector again. Each _can_ represent about 20% speedboost; although sometimes due to other hardware optimizations AVX isn't faster then Generic build.
Thanks for a good explanation!
Having some issues though trying to run it with more than 4 hashers.
Trying to run with 7 hashers gives me the following issue:
You have 8 processors vs. 7 hashers.

Also puts my hashrate at around 5.9 with the i7 7700k which should apparently produce 8-11 H/s.
Any idea how to fix this?
