Processor
- the "Central Processing Unit" (CPU); the principal integrated circuit used for
doing the "computing" in "personal computer"
Front Side Bus Frequency -
The working frequency of the motherboard, which is generated
by the clock generator for CPU, DRAM and PCI BUS.
CPU L2 Cache -
The flash memory inside the CPU, normally Pentium III CPU has 256K or
above, while Celeron CPU will have 128K.
The way to recognize the specification of CPU from the packing Pentium
III 370 pins FC-PGA
On the surface of the CPU as shown on the right picture, under the word of
“PENTIUM III” the code is:
RB 80526 P2 866 256
RB :
FC–PGA packing
P2 :
P2–133MHz front side bus frequency
PY–100MHz front side bus frequency
866 :
CPU internal frequency, where here is
866MHz
256 :
the size of L2 cache, where here is 256K
Celeron FC–PGA
On the surface of the CPU as shown on the right picture, under the word of “Celeron” the
code is:
566/128/66/1.5V
566 :
CPU internal frequency, where here is 566MHz
128 :
the size of L2 cache, where here is 128K
66 :
front side bus frequency, where here is 66MHz
1.5V :
the voltage for the CPU
