Re: [ANN] sgminer v5 - optimized X11/X13/NeoScrypt/Lyra2RE/etc. kernel-switch miner
what is the current expected speed on QUBIT for 7950s and 280x?
I have 3x 7950s and 2x 280x...just dont know whats "normal"
pertinent settings are:
Any advice for improvement would be appreciated

Just ran a couple of quick tests, the first on SGMiner 5, right from Github. The source I used was a bit old, because I forgot to pull before I did the test, so for reference, I used commit f27f8dd544a107523435363e7b26bfc294719542, pushed on Tue Jan 13 11:00:57 2015 +0100. I highly doubt anything in Qubit has changed since then, however. Anyways, the rig I tested on, Freya, currently has a 270X, 280X, 290X, and 7950. The cards are OC'd - card types, clocks, and memory types are in the notepad.

I also spent maybe 2 - 3 hours or less on Qubit a while ago one afternoon. As such, the results are approaching barely acceptable in my opinion, but I did it just for the hell of it. Maybe I'll finish up with all the more obvious hashrate increases to be had at some point, then clean and polish the code, but not now. Nevertheless, here it is:

DAMN!!!
Wolf0, thats more than 50% increased hashrate!
You are definetely doing some real magic on that code...
