this is GatelessGate:


I have also SGMiner-GM that gives higher rate (2-3%) but it produces way more rejects on XMR dwarf(even with no stale shares submitted), while it could do just fine with monero clones on other pools.
Had no time to check whether these rejects are of any substance, but it hurts my eyes:)

EDIT: Note that Samsung mem on 470 is set to 1750MHz, it's because it gives higher rates than on 2000MHz and this is a complete mystery to me... No mem errors and same GPU mem timings. Algo seems to be getting a boost from some "good sync" issue.
