I've been using a Pentium II 450MHz processor and recently acquired a Celeron 633MHz processor. I was wondering what the difference is between a Celeron and a Pentium processor and which processor would be faster/would you recommend. Thanks.

I have heard Pentium processors are better than Celeron. Please give your opinion about Pentium V. Celeron :-)

Well... The Instruction sets of pentiums are better so they can do the work faster than celerons, even on the same clock speeds. Since the celeron you are talking about has a higher one, it will probably outrun a pentium for normal use (typing, internetting, emailing). But a pentium might perform better on the territory of multimedia and stuff..

I suggest you first try both of them to see which one is better. use sysmark or something.

Also, are you sure the celeron would FIT in your motherboard, since the p2 uses a special slot on the motherboard. So i doubt it if it would fit in the computer anyway.

For Pentium 4 compatable Celeron processors, the same die is used for both processors. The difference is that the Celeron processor in without as much level two cache. Usually half of the same Pentium 4 processor. Additionally, Intel continues to use an outdated Pentium 4 die as a new Celeron ie. .09 micron compared to .13 micron.

Still more, some Celerons were Pentium 4's that were either substandard or intentionally retarded to be packaged as Celerons. The longer a processor is made, the higher the yield of higher performance processors. As a result, Intel has to lock the clock on many 3.2GHz chips to be able to sell them as 2.0GHz chips. This is because as their process improves, the lower clock speeds are less predominant.

As far as instruction sets, my understanding is that they are the same although new versions of a chip will have better instructions than their predecessors.

I imagine that you will see an increase in performance by installing the higher clocked Celeron.

Happy upgrading,

Thnaks guys, maybe I will take the time to do a test, but I will probably just switch to the Celeron. I don't have to worry about the chipset because along with the Celeron came a computer. The reason I even asked this is I'd have to take compnents out of my current PII to max out things like memory on the Celeron (It only has 64MB).

I'm using Celeron 2.4GHz. I chose it becouse of low price. And it's enought for gaming, surfing and software (Okey okey, I know it's never enought... ).

Main differences between Celeron and Pentium (socket 478 models):

• Celeron has 128kb cache (Pentium usually has 2x or even 4x bigger one)
• Celeron doesn't support Hyper-Threading (faster multi-tasking technology)
• My Celeron is able tu use only DDR266 memory speed (I have one 512Mb DDR400 RAM module, so it's not running at full speed)

Celeron is about 20% slower than Pentium with same clock speed. In some software there are no big performance difference. So if you want cheaper CPU, choose Celeron, but know this: Pentium beats Celeron in every performance test.

P.S newer Celeron models (Celeron D) have 533Mhz bus (instead of old 400Mhz) and 256Kb cache (instead of 128Kb)...

Thanks it sounds like the Celeron is a better choice for me. If it is 20% slower than than the listed speed that makes it 506.3MHz processor which is still faster than 450MHz. I'm going to switch the stuff this weekend.

Hmm...I heard celerons were 33% less efficent then pentiums.

I'm thinking of upgrading from celeron to pentium...But would I have to get a completly new mother bother or no?.

My current celeron chip is: celeron ® 2.2ghz...Think A p4 with ht tech would fit in there?

It depends on what Celeron chip you have (do you know model number?) and what p4 with ht you want, but I would think probably. It looks like a no from the Intel site: http://www.intel.com/design/chipsets/mature/index.htm

We'll im not an intel guy, i use AMD but my Linux machine is a PIII. The celeron lets just say is a budget porcessor and is little outdated i suggest keeping the pentium!

i thinkn it really depends on what you want your processor to do, like office work and stuff, the easy stuff maybe you should go for the intel celeron.

but if your going to use it for the multimedia stuff like games, videos, music etc. your better off with the pentium as it is stronger and obviously more expensive.

if your thinking of buying a new processor try and get the AMDs. to me i think intel is just a brand. AMD was made atfer intel but much more better. its even made by a group of people that think intel are just slow. and EXPENSIVE.

so try to get amd althon 64 the newest processor out. it would last you for quite long maybe another eight years until its outdated, not like 2 years.
