Hi everyone,

I've got two computers, a Pentium PC and an Intel Celeron laptop. (The first one is five years old and the second is one year old).
I tend to use the laptop for the whole of my translation work (because using the family computer to work wouldn't be that safe), but now I've been contacted by a translating/subtitling company and their software has got some system requirements that don't match any of my computers.
It requires a Pentium 4 processor and they have told me to avoid installing their software in a computer with Intel Celeron processor. My question is, do you think it's possible to install a Pentium 4 processor in my laptop, swapping it with the Celeron? I've been told by a friend that it's impossible and that the only solution to this is buying a new computer (since it's also impossible to change a Pentium into a Pentium 4). What do you think? I've tried to get professional help, but it looks like every place I've been to is closed lol. So meanwhile, I've decided to ask you, because I don't have that much experience in terms of hardware.

Cheers from Portugal and I hope this doesn't sound too silly! lol

better try it first Feb 15, 2007

I worked with thousands of programs before, but I never heard any application-level program that can work with Pentium 4 but not Celeron. It's not a typical requirement for a translation program.

If it does not hurt trying, then I suggest you try it on your computer first.

The only possible situatoin I can imagine to differ between Pentium and Celeron is an unfortunately badly written evaluation module of the program. Sometimes programmers use kernel-level codes here. But also, the worst thing to happen is the program itself crashes, rather than anything in your computer is badly influenced.

You cannot upgrade a processor in a laptop Feb 15, 2007

or at least not at reasonable cost.
The same is with your older PC, where you cannot install Pentium IV without replacing the mainboard.

I also have not heard, that an application running on P IV wouldn't do that on Celeron, but one never knows...
So just ask that you would try it.
If it works, than you have no problem. If it doesn't, you will need a new laptop (or PC).

AFAIK, Celeron is just slightly slower Feb 15, 2007

Hi Teresa,

When I bought my newest PC about 2 years ago, I did a little research about the pros and cons of Pentium vs. Celeron PCs.

In this article, you will find a quick explanation:

So it seems basically that Celeron PCs are slightly slower, but they are capable of running pretty well for most of the programs we use for translation, as you must have confirmed yourself with your Celeron laptop.

So unless the application you need to install for your translation is very heavy, say in graphics (like videogames), I don't think it should be a problem. I have installed, for example, AutoCAD-related programs when localizing some related software and I never had a problem.

Celeron's got less cache Feb 15, 2007

Celeron and P4 are the same processor except that Celeron has got less fast memory (cache) on it and thus runs slower. As far as the on-chip instruction set is concerned they are the same. Qualitatively the software runs on P4 also runs on Celeron, but quantitatively slower on Celeron.

Just sharing experience Feb 15, 2007

As a Bussines & System Consultant I've had the experience that Celeron processors some times do "weird" thing. In the last four years I've registered in my log book155 problems regardind the performance of different applications, solved by means of changing the processor. Out of the total, 74 were Celeron's, 14 Pentium, 22 AMD and the rest other brands.

As a result of this -and comments from hardware specialists- I avoid celeron in my computers and switched to AMD Athlon which turned out to be far cheaper and quite reliable.

It's just a personal experience.

On the other hand, it is usually true that you can not upgrade your processor without changing the motherboard, as well as the fact that there are applications that won't run well under certain processors. I call it "programmer's idiosyncratics"

Hope you can solve it without a great expenditure!

Not exactly true..... Feb 15, 2007

I'm no computer expert but the motherboard I put in my PC three years ago is compatible with both Celeron and Pentium processors, although sadly not with the new dual-core processors that are now on the market. When I upgrade later this year I plan on changing my Celeron processor, which has worked perfectly fine all these years, for a Pentium 4, which have come down a heck of a lot in price, and giving the old computer to the kids. As far as I'm aware the only major difference between the two is that a Pentium is faster.

I would not do it Feb 16, 2007

Pentium 4 energy requirements will overheat your lapotop.
My experience with a Toshiba Satellite A60 with pentium 4:

- First you notice more fan noise,
- Then your fingers get unconfortable from heat
- Computer shuts down for overheating with increasing frequence
- Your HD gets damaged.

My advise is keep your Celeron or switch to a PC or to a new Notebook with a low energy processor like Centrino Duo or similar.

You cannot replace processor, but you can install the programm Feb 16, 2007

Hello Teresa,

Don't worry.. Any application that runs on Pentium processor will run on Celeron.. the main difference between both processors is the way each one deals with arithmatic problems, which Pentium is much faster than Celeron. Other features includes cache memory...

BUT this doesn't mean that you can't install your application, as Intel processors are nearly same, i.e this is not G3 processor for example that is used with Macintosh systems.

So, you can install it without any doubt.

regarding updating your laptop, you can only if your motherboard accepts this. Yet, in view of the fact that you own your laptop since a year, I doubt that you can upgrade the processor to Pentium. You know what? The processor is the most expensive piece in a computer/laptop. My advice then is: Buy a new laptop and enjoy new speeds

Kind regards,

A new PC on the way Feb 16, 2007

Thanks everyone, for your help and advice.
I cannot indeed update nor my laptop, nor my old PC. It would be almost impossible and even more expensive than buying a new computer. It's an investment and I'll do it, because I don't want to lose contact with this company.

I forgot to say that the company will only send me the software if I prove to have a suitable computer to install it, (a Pentium 4, at least) therefore buying a new equipment is inevitable.

Late comer Feb 25, 2007

My comment is probably too late to make any difference now but my advice would be to follow the advice of Luca Tutino, go for a laptop with an Intel Centrino Duo processor. It will keep you going for a few years.

Good Luck
