Here are the most important similarities and differences between the Pentium 4 and the Celeron chips coming out today:

Core - The Celeron chip is based on a Pentium 4 core

Cache - Celeron chips have less cache memory than Pentium 4 chips do A Celeron might have 128 kilobytes of L2 cache, while a Pentium 4 can have four times that The amount of L2 cache memory can have a big effect on performance

Clock speed - Intel manufactures the Pentium 4 chips to run at a higher clock speed than Celeron chips The fastest Pentium 4 might be 60 percent faster than the fastest Celeron

Bus speed - There are differences in the maximum bus speeds that the processors allow Pentium 4s tend to be about 30 percent faster than Celerons
