@ all : hello !

 

I would like to know what is the best subarch for my computer. The fact is that i'm not a expert in the processors...

 

The informations :

# dmidecode --t processor
# dmidecode 2.12
SMBIOS 2.5 present.

Handle 0x0004, DMI type 4, 40 bytes

# cpuid | tail -n 1
   (synth) = Intel Pentium Dual-Core Desktop Processor E2000 (Allendale M0), 65nm

So, core2_64 or corei7 ? I think core2_64 but i'm not sure...

 

Thank you for the answer, and sorry for this question of beginner...

Thanks a lot !

 

When you know where to look, it's easier of course...

Gcc supports a "native" target where it detects what cpu its running on and then uses that for almost code generation options.

 

Unless you build on a host that is different from the target, why not use this feature?
