7950 @ 1080/100 and drivers 13.12 = 11 Mh/s
7850 @ 1100/100 and drivers 14.6b = 12.5 Mh/s
7950 @ 1080/100 and drivers 14.6b = 21 Mh/s
I heard people with 280x have approx 30 Mh/s...
EDIT : Myriadcoin-groestl
Yes, this seem quite low for the optimized kernel. I'm not sure about 30MH/s on R9 280X (I have 33MH/s on R9 280), but 21MH/s on 7950 seem to be low.
Please send your command line.
You are using -k myriadcoin-optimized, right?
Because if you are using just the normal -k myriadcoin-groestl, that's pretty much what you should be getting.
Thanks

On the last miner i was using i had 17 Mh/s instead of 21 Mh/s for my 7950.
