i havent mined Bytom for a bit, but i just grabbed that latest "Nebu_Tech" miner and tried it. id say 1000h/s is surely doable
mine did 950 out the gate @ a simple 1950 clock, im sure if others got their core to 2050-2100 it would be over 1000h/s  

@ 72% PL it does 825 still, this is matched with an 8700k, in a desktop workstation, not a rig , and i believe x8 pci-e
(MSI FE 1080ti)
