Cpu speed comparison

[MedRNurse]

Hello,
I need to replace my CPU, and have been trying to pick between 2.0 and a 2.4GHz, 400Mhz, 512KB I presently have a Pentium 4 1.6 Ghz, 400Mhz, 256KB and would like to go with either of the above.I'm I going to really see a difference?

What two CPUs are you looking at? Are they both Pentium 4's with the same code name? If they are not you cannot compare on clock speed alone.

What are your computer uses and what do you want to speed up? Let's make sure they would provide the performance improvement you need.

Can you at the very least give us the cache amount for the 2.0GHz p4, if not, the model numbers for all 3 processors?

Both CPU's are Northwood. The problem I having is finding a 2.2 or a 2.4 that are not 533MHz. I understand that I can not jump from 400MHz to a 533MHz.

We'd need your motherboard model to ensure compatibility. I have several pentium 4 motherboards that I've used as my server and recently had to ditch one. I'd gotten a 2.8GHz pentium 4 with HT but after reading I found out the motherboard only supported up to 2.4GHz 400MHz.

If you are in Canada, I have two 2A Pentium 4's just sitting on my desk and a celeron 2.4GHz that I believe is at 400MHz FSB.
If not, you could try searching the model numbers on ebay for the 2.4 with a 400MHz FSB:

^the above site can be used to find the model numbers.

Impossible to say without you telling us what tasks you want to see a difference in. And the rest of your system configuration.
If it is an OEM machine, the model number of the machine as well as the brand (hp etc) would be invaluable.
