Do you have more info on that? Try:
grep 'model name' /proc/cpuinfo
Well, $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.06GHz stepping : 9 cpu MHz : 3058.795 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm constant_tsc pebs bts pni monitor ds_cpl tm2 cid cx16 xtpr lahf_lm bogomips : 6117.59 clflush size : 64 power management: processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.06GHz stepping : 9 cpu MHz : 3058.795 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 apicid : 1 initial apicid : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm constant_tsc pebs bts pni monitor ds_cpl tm2 cid cx16 xtpr lahf_lm bogomips : 6118.20 clflush size : 64 power management: Does that mean two CPUs, each with two siblings, or what is the correct interpretation?
The original Pentium 4 (eg "Intel(R) Pentium(R) 4 CPU 3.00GHz") had hyperthreading which was actually pretty pathetic for parallelism.
The Core 2 Duos (eg "Intel(R) Core(TM)2 Duo CPU T9600 @ 2.80GHz") are far superior.
But probably also far more expensive :) I bought something cheap and was actually surprised when I discovered that it seemed to have two Cores/CPUs.
