3.8 GHz P4-570 and E0 Stepping To End Intel's Performance Crisis
How To Find Your CPU
You will find the SL-SPEC numbers on the processor box label. There is also a little window that allows you to inspect the processor yourself.
We recommend putting together a list of the features you personally consider mist important. We believe you shouldn't go without Thermal Monitoring 2 and the Enhanced Halt Mode C1E, since these are what make the P4 Prescott really interesting for the first time. Then, simply check the SL-SPEC number that matches your favorite version and insist on that one when buying.
