Here's the information from my dual-core athlon processor. Again, the format is CPUID proc_id core_id (sibling mask) (core mask): CPUID proc_id core_id sibling_mask core_mask 00 00 00 (00) (00,01) 01 00 01 (01) (00,01) As you can see, the processor ID refers to a single package (with ID 0), and the core ID is different for each CPU, as expected.
