Pentium 4 vs. Celeron D

Although you would have to look at the steppings, in the end Intel was selling Celerons as renamed older P4 cores *IE the Northwood Cores/Prescott*, which is probably what your old P4 is.

the Celeron D *which is not a dual core, tricky marketing* is to differentiate the Celeron built using the Prescott core from the one that utilizes the Northwoord Core. The Prescott Celeron *Celeron D* Has twice the memory l2 cache compared to it's older Celeron *Northwood core* Brother, and also supports stuff like EMt64 etc...

In other words, the Celeron will be faster, as while it is stripped down slightly, it is based on the newer Prescott Core, while your P4 is probably Northwood. Had your P4 had HT or something, it would make the winner unclear, but since it doesn't it's safe to say the Celeron D wins.

Jam it back in, in the dark.

I'd stick with the P4 because if there's any gain, it's very little gain. Prescotts get very hot anyways, so I wouldn't do it, not worth it to take apart your computer just to fit a processor that is marginally, if at all, better.

I found that out here if you want to look it up.

Ah, so I was mistaken about the EMT64 support, I was going by memory on that one. We also don't know how much cache his current P4 has, or what FSB it boasts etc.. *although it would help if he wanted to check via Cpu-Z when he gets a chance, probably 512 and 533fsb though*. While the extra l2 cache is nice, it does only help in certain situations *mostly video and sound rendering etc..*. If he wants to OC, then yes, his P4 would probably be the better choice. If not, the Celeron D might be a slightly better choice.

There's nowhere I can't reach.

Ah, it's a Northwood. You might as well stick with your P4. As the others said, the difference in speed is very minor, and the p4 with even just a bit of ocing will come out on top easily. also, you have one of the later Northwood core's that have the 800FSB and Ht *before, the northwood only had 533fsb, and only the top of the line 3ghz+ had HT*.

The Voltage is somewhat high on your p4, but that's to be expected.

This thing is sticky, and I don't like it. I don't appreciate it.
