I first discussed processor speed in tip 1949.
To retrieve processor make, model, and speed, I have scripted CPUMMS.BAT,
using REG.EXE on Windows 2000, from the Windows 2000 Support Tools,
or REG.EXE built into Windows XP.
The syntax for using CPUMMS.BAT is:
call cpumms \[cpu\]
where cpu is an optional CPU number. If you have a multi-processor,
the first processor is 0, the second is 1, etc...
If the cpu parameter is omitted, 0 is used.
The routine returns:
Environment Variable Name | D E S C R I P T I O N |
---|---|
vendor | The manufacturer's identification, like GenuineIntel. |
model | The model information, like x86 Family 6 Model 8 Stepping 1. |
MHZ | CPU speed, like 800. This is an arithmetic environment variable. |
If you enter a cpu parameter that does NOT exist on this computer,
the environment variables are NOT set.
The easiest way to test for this is:
if not defined MHZ goto label
CPUMMS.BAT contains:
@echo off if \{%1\}==\{\} set cpu=0&goto find set cpu=%1 :find call :look >>nul 2>>&1 set cpu= goto :EOF :look set vendor= for /f "Skip=3 Tokens=2*" %%i in ('reg QUERY "HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\%cpu%" /v VendorIdentifier') do set vendor=%%j set model= for /f "Skip=3 Tokens=2*" %%i in ('reg QUERY "HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\%cpu%" /v Identifier') do set model=%%j set MHZ= for /f "Skip=3 Tokens=2*" %%i in ('reg QUERY "HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\%cpu%" /v ~MHZ') do set /a MHZ=%%j set cpu=
