Why aren't the CPU core numbers in sensors output consecutive?

The core number is 0,4,8,.....39 in the sensors command. Why not 0,1,2,3,4.....?

foo@foo-linux:~$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +73.0°C  (high = +80.0°C, crit = +100.0°C)
Core 0:        +46.0°C  (high = +80.0°C, crit = +100.0°C)
Core 4:        +50.0°C  (high = +80.0°C, crit = +100.0°C)
Core 8:        +52.0°C  (high = +80.0°C, crit = +100.0°C)
Core 12:       +47.0°C  (high = +80.0°C, crit = +100.0°C)
Core 16:       +73.0°C  (high = +80.0°C, crit = +100.0°C)
Core 20:       +50.0°C  (high = +80.0°C, crit = +100.0°C)
Core 24:       +58.0°C  (high = +80.0°C, crit = +100.0°C)
Core 28:       +52.0°C  (high = +80.0°C, crit = +100.0°C)
Core 36:       +48.0°C  (high = +80.0°C, crit = +100.0°C)
Core 37:       +48.0°C  (high = +80.0°C, crit = +100.0°C)
Core 38:       +48.0°C  (high = +80.0°C, crit = +100.0°C)
Core 39:       +48.0°C  (high = +80.0°C, crit = +100.0°C)

**update again** This is a 12th Gen Intel(R) Core(TM) i7-12700 This is a PC, not a server, with only 1 CPU socket. **update**
