ufasoft cpu miner i have found gets the best mh out of intel cpu's i currently get 7-8 out of a 1.6ghz i7-720m, the theroetical limit of ufasoft is 1mh/1ghz per core on intel cpu's HT seems to be giving some form of benifit since that formula would put me at 6.4
Do you do this for academic purposes? I have a few HD 4850 cards that are putting out 80 Mhps and I am contemplating whether they should be turned off due to the inefficient Mhashps/joule ratio.
