i currently have an old slot 1 300A celeron overclocked to 450, and have been looking for a new cpu. the real question that i have is that my friend told me that even if i get a 700 celeron, i wont see much of a speed difference performance-wise. is this true?

>, i wont see much of a speed difference performance-wise.
**DISCLAIMER: I'm far from an expert in proc changing. Usually I'll just get a whole new mobo.**

Okay, with that out of the way...
If you have a BIOS that allows you to change your front side bus (usually it'll have it listed after the speed of the processor, something like 300(100) or 500(133). The speed in parenthesis is the FSB speed. If you can upgrade your processor *and* the FSB, you can have a noticable speed improvement (at least, so has been my experience), but if you have to keep your old FSB, you're likely to get better performance from a new mobo + proc.

the FSB is actually the memory speed. even if your mobo does support 133 FSB, your memory might not and well it just gets quite confusing and i dont know much about all that stuff but every time ive upgraded my comp, i've upgraded to a completely different CPU so i needed new a Mobo.

a 133 Pentium
to a 300 P2
to a 1.2 GHz Athlon

but i could tell the diferance substantially between my comp and my brother's who has a 900 Athlon it starts up faster and runs smoother although he has a better graphics card and running unreal tourney has sharper images mine still runs smoother

The higher the frequency, the higher the speed (AUTOMATICALLY!!).
But I wouldn't recommend a celeron anyway; if you're looking for a low-cost processor, get an AMD Duron 850 or 900 on a new motherboard.
If you have enough money, I would recommend to get one of the new C-Athlon with 266 MHz FSB and DDR-RAM.

 

[campaign2016]

thats not always 100% true
at these higher frequencies of today, memory speed was becoming a bottle neck. it just couldnt get enough information to the prossecor to show that much improvement when upgrading

DDR ram as you stated is 266 while the memory in most current systems is either 100 or 133

 

[strider999]

what if i just got a 700 p3 instead of a celeron? (i really dont feel like getting a new mobo) how much of a performance increase would i get. currently running a p2 300A celeron overclocked to 450.

 

[bobotns]

You get three things when you use a pIII:
1) you get a faster FPU
2) you get a larger memory bandwith (especially when you use 133MHz processors, like the 667 or 733)
3) you get a larger and faster cache
Estimated performance: min +50% in comparison with your celeron

CONCLUSION: if you can install a PIII processor, do it!

NB: the PIII's with 100 MHz have a better overclocking potential.

Don't forget that Intel cut a LOT of corners with the Celeron processor, so a P III would be much better. That's one of the reasons why the Duron processor is beating the tar out of Celeron processors right now (cheaper prices and fewer limitations=big bucks for AMD).

As campaign2016 said that's not always true,the best ex. is the P4,it's faster than the Athlon but It doesn't perform as well as the Athlon(for the moment).
Bye.

 

[bobotns]

I ment: for a definite processor class!!!!!

 

[Raziel]

OK,excuse me bobotns but it wasn't really obvious(is that the right word?).
Bye.

I also thought you meant a higher processor cycle is faster, regardless of the kind of processor. The problem is that what some people may assume will be known when saying something (particularly online) is not necessarily what others will assume.

The 66Mhz fsb is probably the most limiting factor, it's a shame intel only recently started to ship celerons rated for 100 fsb. If you have an intel mobo and limited cash it may be cheaper to buy a celeron 633 and put it at 100 fsb, the resulting 950Mhz clock rate is highly attainable for most celeron 633's it seems. Also, the pci and agp clock divisors will produce in spec frequencies at 100fsb, so as long as the cpu can handle it, the overclock will be stable.

I didn't have alot of cash when my last processor blew, so my friend helped me get a celeron 600 going at 900 and it was only $60 US. That was back at the beginning of the year though so its probably even cheaoer now.
