Any difference between Pentium III and IV

Any difference between Pentium III and IV?

Answer:

There have been a number of Pentium processor lines starting with the base Pentium in 1993.The of the recent Pentium entries are Pentium III and Pentium 4.

a)     In a Pentium III processor, the bus speed is generally 133 MHz (although there were a few with 100 MHz). The lowest bus speed on a Pentium IV is 400 MHz, and there are versions with much higher speeds (topping at 1066 MHz for the "extreme edition").

b)    The Pentium 4s are smaller than the Pentium IIIs

c)     Pentium III processors had (for the most part) about 512 KB of cache. Pentium 4 processors, on the other hand, start at 512 KB.

20) What are the differences between Intel Celeron and Pentium family of Processors?

Celeron

• According to Build Gaming Computers, Celeron processors are the low-end processor intended for standard home computer use. SciNet reports the best Celeron processor has an L2 Cache of 128kb, a clock speed limit of about 2.0 GHz and runs at a core voltage of 1.75V. These are useful numbers for comparison.

Pentium

• The top Pentium processor is the Pentium 4 Prescott. CPU Scorecard reports it has an L2 cache of 1MB (1024kb), a potential 3.0 GHz clock speed and runs at about 1.4V. The lowest performing Pentium 4 processor, the Willamette, has an L2 cache of 256kb, a potential 2.0 GHz clock speed and runs at about 1.7V.
