Maybe this can help you:

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.

The average programmer productivity is 4-5 hours per day. Peak performance 72 hours for short bursts. MTBF is 1 second or less.

Some CPUID uses have been preprepared in the cpu unit:

Code: Pascal  [Select][+][-]
  1.  
  2.     { returns true, if the processor supports the cpuid instruction }
  3.     function cpuid_support : boolean;
  4.  
  5.     { returns true, if floating point is done by an emulator }
  6.     function floating_point_emulation : boolean;
  7.  
  8.     { returns the contents of the cr0 register }
  9.     function cr0 : longint;
  10.  
  11.     function InterlockedCompareExchange128Support : boolean;
  12.     function AESSupport : boolean;inline;
  13.     function AVXSupport: boolean;inline;
  14.     function AVX2Support: boolean;inline;
  15.     function AVX512FSupport: boolean;inline;    
  16.     function AVX512DQSupport: boolean;inline;    
  17.     function AVX512IFMASupport: boolean;inline;    
  18.     function AVX512PFSupport: boolean;inline;    
  19.     function AVX512ERSupport: boolean;inline;    
  20.     function AVX512CDSupport: boolean;inline;    
  21.     function AVX512BWSupport: boolean;inline;    
  22.     function AVX512VLSupport: boolean;inline;    
  23.     function FMASupport: boolean;inline;
  24.     function POPCNTSupport: boolean;inline;
  25.     function SSE41Support: boolean;inline;
  26.     function SSE42Support: boolean;inline;
  27.     function MOVBESupport: boolean;inline;
  28.     function F16CSupport: boolean;inline;
  29.     function RDRANDSupport: boolean;inline;
  30.     function RTMSupport: boolean;inline;
  31.     function BMI1Support: boolean;inline;
  32.     function BMI2Support: boolean;inline;
  33.  
  34.     var
  35.       is_sse3_cpu : boolean = false;
  36.  
  37.     function InterlockedCompareExchange128(var Target: Int128Rec; NewValue: Int128Rec; Comperand: Int128Rec): Int128Rec;
  38.
