Intel brings Pentium 4 and Celeron with only 1.475 volts

Intel announced today that all Intel Pentium 4 and Celeron processors, which are manufactured in 0.13 µm and are based on the Northwood core, will soon be offered with three different Vcore settings. The range extends from 1.475 to 1.525 volts.

This means nothing other than that Intel now uses each processor individually tests and determines the appropriate operating voltage based on the stability results. Only the best of them get the honor of being allowed to operate with 1.475 volts. So 0.050 volts less than the 1.525 usual for the Pentium 4 with C1 stepping . Due to the lower operating voltage, the processor's power loss is also lower. From December 6th, the current top model, the 2.8 GHz Pentium 4, as well as the 2.66 GHz variant with 'multiple' voltages will go on sale. On January 24th, the complete Northwood portfolio (currently Pentium 4 1.8A to 2.8 GHz, Celeron 2.0 GHz) will be available with different voltages.

Along with this change, Intel has launched the new S -Spec codes for the processors, which are as follows.

S-Spec code for multiple VID processors
C1 Stepping (Fixed VID) C1 Stepping (Multiple VID ) Pentium 4 0.13µm, 512kb L2 1.80A SL6LA SL6S6 2.00A SL6GQ SL6S7 2.20 SL6GR SL6S8 2.26 SL6DU SL6RY 2.40 SL6GS SL6S9 2.40B SL6DV SL6RZ 2.50 SL6GT SL6SA 2.53 SL6DW SL6S2 2 , 60 SL6GU SL6SB 2.66 SL6DX SL6S3 2.8 SL6HL SL6S4 Celeron 0.13µm, 128kb L2 2.0 SL6HY SL6RV

Because Intel has the S-Spec code for all processors with a clock frequency has forgiven, hide them ch behind this code three different onesProcessors. Ultimately, you will only know with a look at the heat speader whether you caught the model with 1.475, 1.5 or 1.525 volts.
