Is there any way to tell which AMD Opterons have the lzcnt feature? Backstory: I have a couple of 4 socket Tyan s4985g3nr motherboards that currently have Opteron 8216's in them. I can only upgrade to these models of the Opteron: 8346HE, 8347, 8347HE, 8350, 8350HE 8354, 8356, 8358SE, 8360SE (www.tyan.com/support_download_cpu2.aspx?socketid=16) Where can I find out if any of these models support lzcnt? According to Wikipedia, the Barcelona architecture has lzcnt. According to Tyan, those models listed above are Barcelona's. I just can't seem to find anything that says "These CPU models support lzcnt:" Thanks in advance! --Joseph _______________________________________________ rc5 mailing list rc5-Ra3b/QYEcJ3d140v2zMXi0fjHoOT/h/[email protected] http://lists.distributed.net/mailman/listinfo/rc5
