Xeon X3220 Dual-Core 2.4 GHz - which march setting for gcc?
- by hurikhan77
Should I use -march=nocona or -march=core2 when compiling binaries for this processor with gcc 4.3?
vendor_id : GenuineIntel
cpu family : 6

I cannot really find if this CPU is already core2 architecture... Only find information about the quad core variants, but this CPU is only dual core.
