Hey, Spexx - I saw your challenge posted, but didn't really like it because you stated that modifying the miner code itself is disallowed. So, just for fun, I worked on my own, cross compiled it from Linux, and then ran it on my laptop, which dual boots Windows and Linux. (I figured I should benchmark both miners on Windows to be fair.)
The laptop has an i7-4700HQ CPU, clocked at 2.40Ghz. I took the hashrate of each miner and rounded to the nearest quarter kilohash.
Your AVX2 miner: 28.75kh/s
My AVX2 miner: 51.50kh/s
Difference: ~79.13%

On Linux, it can reach just under 60kh/s, but I don't think that's a fair comparison.
Give it to us now
