What is the diffrence between Pentium and Celeron proccessors?

Question

I got confused. I have 2 PCs, one in my home and the second in my office.

Processor: Intel(R) Celeron(R) CPU 3.06GHz, ~2.3GHz

Processor: Intel(R) Pentium(R) 4 CPU 2.20GHz, ~2.2GHz

As u see the frequencies of processors are nearly the same but why the Celeron (R) is running slower than Pentium(R)?
RAMs are the same in both,512MB

Answer 1

In summary, the main differences between Celerons and Pentiums are in the areas of bus speed and L2 cache features. Both Pentium-II's and -III's ship with 512kB of secondary (L2) CPU instruction cache. This allows the CPU to store recently used instructions close by and is responsible for much of their high performance.

The Celerons that Intel first introduced as a low-cost CPU alternative (266 & 300MHz versions) were basically just Pentium-II's without any L2 cache at all. This deficiency really punished Celeron performance when compared to competitive AMD and Cyrix chips. In response, subsequent Celeron versions (300A and up) were provided with 128kB of L2 cache. Though only one-quarter the size of the Pentium cache, it was built to run at the full speed of the respective CPU, rather than at half-speed as in the Pentiums. Due to its higher manufacturing cost and technical issues, the larger Pentium cache memory has always been set to run at only half the speed of the CPU itself. For a full-speed L2 in a Pentium design, you need to get into Intel's (much more expensive) Xeon line.

What Intel plays down-- but nearly everyone knows-- is that the full-speed, quarter-size Celeron cache gives them almost the same performance as the half-speed, full-size cache gives Pentiums. Thus you'll find that, for most applications, Celerons rated at the same MHz will equal or better an equivalent Pentium-II, for a much lower price.

For example:

Celeron @ 466MHz x 128kB L2 @ 466MHz =>
Pentium-II @ 450MHz x 512kB L2 @ 225MHz

Pentium-III's are given an added boost with an inherently faster system bus speed (100MHz vs. 66MHz for the Celerons) and Intel's new SSE 3D instruction set. This combination of hardware and firmware enhancements gives Pentium-III's a significant edge over the Celeron's smaller cache and slower bus.

Answer 2

The Celeron is an 'efficiency' chip. It run's slower, burns hotter than a Pentium. It also will sit on a different type of motherboard. It also doesn't have the 'cache' of the Pentium so accessing information takes longer.

Answer 3

ur question is differentation within celeron and pentium 4. that processors is developed by Intel. processors is like a brain that generate everything on pcs. just celeron is slower from p4, look at the year it developed.
types of processors:
* AMD K5
* AMD K6
* AMD K7
* AMD Athlon
* AMD Duron
* AMD Opteron
* AMD Athlon 64
* AMD Sempron
* AMD Turion 64
* Intel Pentium
* Intel Pentium MMX
* Intel Pentium Pro
* Intel Pentium II
* Intel Pentium III
* Intel Pentium 4
* Intel Pentium D
* Intel Pentium Extreme Edition
* Intel Celeron
* Intel Xeon
* Intel Pentium M
* Intel Core
* Intel Core 2
* Cyrix 586
* Cyrix 686

i sugest u use intel core, hehehehehe, if u r a gamer ;p

Answer 4

It's the stepping speed of a processor. Celeron's are slower and not good for gaming, whereas Pentium 4's cruise the fast lane...

Answer 5

Celeron have lesser Level2 Cache. So, this is a cheaper version of Pentium 4.

Pentium have higher 2nd level cache. Thus it can process instructions faster.

Answer 6

I can only explain as simple as I understood it. A pentium has more on-chip cache memory than a celeron. That's why it's faster.

Answer 7

celeron is slower... I think it's based off of the pentium 3. Anyways, p4 and higher are better.

Answer 8

Celeron is basically a neutered pentium chip its the same with amd's sempron to there amd64.

Answer 9

P4 is faster than the celeron.
