Um, Larry, the P4 is a very old Pentium and new Celerons and Pentiums have very little in common with chips that old. Intel releases a new series of CPUs every 18 months or so and in that series there will be several Celerons and several Pentiums. Newer Celerons are 10 times faster than the P4 ever was, but of course newer Pentiums are faster yet. A CPU that scores over 1200 at Passmark benchmarks will do most anything but anything less and things like video don't work well. If you are considering anew computer, get the exact chip model number and look up the performance score before you buy.
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.Â
