This is maximum number of logical processors per package, not the maximum number of cores. […]
Maximum number is not the same as actual number. The CPU vendor creates a single set of masks, and then probing what is actually working, burn some fuses to make a particular SKU. So you could have CPU ID saying maximum 8 cores, but only 4 are actually active...
