Maybe this can help you:
https://stackoverflow.com/questions/13874152/porting-assembler-x86-cpu-id-code-to-amd64#13876674
You forgot to declare the type of TCPUID.

TCPUId is not declared. You are probably missing a unit.
OTOH the
cpuid instruction
is available for supported Intel/AMD processors.

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.
