I Dont know how this works, but i works thanks to someone on Experts Exchange (dont remember who).

A good advise :

Check some of the previos answered questionon this side:
There is a lot of good stuff (Cheap)

function tmainform.GetCPUSpeed: String;
var
t: DWORD;
mhi, mlo, nhi, nlo: DWORD;
t0, t1, chi, clo, shr32: Comp;
begin
try
shr32 := 65536;
shr32 := shr32 * 65536;

t := GetTickCount;
while t = GetTickCount do begin end;
asm
DB 0FH
DB 031H
mov mhi,edx
mov mlo,eax
end;

while GetTickCount < (t + 1000) do begin end;
asm
DB 0FH
DB 031H
mov nhi,edx
mov nlo,eax
end;

chi := mhi; if mhi < 0 then chi := chi + shr32;
clo := mlo; if mlo < 0 then clo := clo + shr32;

t0 := chi * shr32 + clo;

chi := nhi; if nhi < 0 then chi := chi + shr32;
clo := nlo; if nlo < 0 then clo := clo + shr32;

t1 := chi * shr32 + clo;

Result := Format('%.0f MHz', [(t1 - t0) / 1E6])

except
Result := 'Ukendt';
end;
end;

Another version, it's not my code, but may be useful.

function GetCPUSpeed: Double;
const
DelayTime = 500;
var
TimerHi : DWORD;
TimerLo : DWORD;
PriorityClass : Integer;
Priority : Integer;

begin
PriorityClass := GetPriorityClass(GetCurrentProcess);
SetPriorityClass(GetCurrentProcess, REALTIME_PRIORITY_CLASS);

Sleep(10);

asm
DW 310Fh
MOV TimerLo, EAX
MOV TimerHi, EDX
end;

Sleep(DelayTime);

asm
DW 310Fh
SUB EAX, TimerLo
SBB EDX, TimerHi
MOV TimerLo, EAX
MOV TimerHi, EDX
end;

SetPriorityClass(GetCurrentProcess, PriorityClass);

Result := TimerLo / (1000.0 * DelayTime);
end;

//USAGE:

Label1.Caption := Format('CPU speed: %f MHz', [GetCPUSpeed]);
