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 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
(18 x 133MHz CPU clock);
2A GHz depicts that this CPU is an A version, locked to 2.0 GHz
working frequency (20 x 100MHz CPU clock)
3.06GHz depicts that this is a 3.06GHz hyper-threading CPU
2. CPU L2 Cache: this part depicts the L2 Cache size. For example,
512 stands for 512 KB L2 Cache; 256 stands for 256 KB L2 Cache
3. System Clock: this part depicts the System Clock (Front Side Bus)
provided by the CPU. For example,
533 stands for a 533MHz system clock provided by a 133MHz CPU
times 4;
400 stands for a 400 system clock provided by a 100 MHz CPU x 4.
4. CPU Voltage Vcore: this part depicts the CPU Voltage. For example,
1.5V stands for a CPU of 1.5V Vcore.
Note: System Clock vs CPU Clock
P4 CPU is a quadpumped CPU. The system bus is provided by
the CPU clock x 4. Therefore, users can figure out the P4 CPU
clock by the System Clock divided by 4.
