2-1.1 To Identify a Pentium 4 CPU

Intel
pentium 4
2.4 GHz / 512 / 533 / 1.5V
2) CPU L2 Cache
1) CPU Working Frequency
On the heatsink side of a Pentium 4 CPU, there printed is a line of
figures to identify its specifications. The line consists of 4 parts:
1) CPU Working Frequency: This part depicts the working frequency
of the CPU. For example:
2.4 GHz depicts that this CPU is locked to 2.4 GHz working frequency
(multiplier 18 x 133MHz CPU clock);
2A GHz depicts that this CPU is an A version, locked to 2.0 GHz
working frequency (multiplier 20 x 100MHz CPU clock);
2) CPU L2 Cache: This part depicts the L2 Cache size. For Example:
512 stands for 512 MB L2 Cache; 256 stands for 256 MB L2 Cache;
3) System Clock: This part depicts the System Clock (Front Side Bus)
to be provided by the CPU. For example:
533 stands for a 533MHz system bus provided by this 133MHz CPU
times 4;
400 stands for a 400 system clock provided by a 100 MHz CPU x 4;
(Note: P4 CPU is a quadpumped CPU. The system bus is provided by
the CPU clock x 4. Therefore, user can figure out the P4 CPU clock
from the System Clock devided by 4.)
4) CPU Voltage Vcore: This part depicts the CPU Voltage. For example:
1.5V stands for a CPU of 1.5Vcore.
