If you bench against Claymore 11.3 look at the hashrate reported by the pool, because on my HD7950 rig i have a lower hashrate on screen (559 JCE against 585 Claymore per card) but a better pool hashrate.
on 2G cards (HD7850, 7870) i'm better, even on screen. i never tested on 730
On my Pitcairn 270X 4Gb Claymore 11.3 gives 550 H/s (manual modded bios with OC), JCE after start gives 500-525 H/s. After 10-15 min JCE gives 555-560 H/s.
