It can tell you specified topology, like cores, threads, NUMA nodes. But it can’t tell you the physical locations of cores. Processors are binned based on what cores are functional after fabrication, thus your 12 core processor is probably a 16-18 core processor, and the 4 disabled cores are “random” based on manufacturing defects. Knowing this is completely unimportant, but cool. Ultimately yes, cpuid will tell you and relevant topology, since anything beyond this requires likely trillions of iterations to even detect.
