Windows users have nothing like this. Too bad for them. Although the Phoronix test suite is actually coming to Windows. The Windows version is very alpha right now. Be an interesting twist if Windows users can take advantage of this in the future.
To quote Phoronix.
"The Phoronix Test Suite support on Windows is very early in development and is not targeted for normal end-users with most areas not yet being implemented but will be later on in the Phoronix Test Suite 2.4 development cycle. At this time the Phoronix Test Suite client is dependent upon PHP being installed to C:\Program Files (x86)\PHP\php. The Phoronix Test Suite also uses CPU-Z for much of the hardware detection support on Windows and is dependent upon CPU-Z being installed to C:\Program Files\CPUID\CPU-Z\cpuz.exe."
