For "Pentium D"s yes, they're dual core. However, Intel also offers a "Celeron D" processor, which is not dual core. > Sorry, I not trying to hijack your thread, but I am still confused. > > It has two processor cores, so I assume you'd want to run an SMP kernel. correct > > What's this about running 64-bit Linux? Surely, just because it'll do 2 > x 32, that does not mean it'll also do 1 x 64. ??? I believe almost all of Intel's new chips have their 64-bit extensions, called EM64T. This is where the 64-bit stuff is coming from. Both processor cores will have the 64 bit extensions. If you look at /proc/cpuinfo on a running system, the presence of the 'lm' flag indicates a chip (both Intel and AMD) has 64-bit extensions. For example, from my Sempron64 system: processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 44 model name : AMD Hammer Family processor - Model Unknown stepping : 2 cpu MHz : 1607.987 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni bogomips : 3219.18 -- David W.
