The main thing to keep in mind, when it comes to compatability, is that the
Celeron D runs on a 533 MHz frontside bus, instead of the 400 MHz frontside
bus that the earlier Celerons used. Whether your motherboard will correctly
identify the processor, as compared to whether it can simply handle the
Celeron D, will depend on a BIOS update being available.
AnandTech's review of the Celeron D
(http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2093&p=1) compared an
original Celeron (Northwood core) to the Celeron D, when both were running
at 2 GHz on a 400 MHz, and they noted an improvement in performance from
3-25%, depending on the benchmark. Most of the benchmarks showed at least a
10% increase in performance. When the Celeron D is running on the 533 MHz
bus that it was intended for, the performance increase will be even better,
due to the increased memory bandwidth available.
Anandtech didn't include a Pentium 4 2.0A processor in their comparison, but
they did use a Pentium 4 1.8A (which runs on a 200 MHz frontside bus), and
the Celeron Ds they looked at (ranging in speed from 2.53 MHz to 2.8 MHz)
were all faster than the Pentium 4 1.8A.
You can find other reviews of the Celeron D at other hardware review
websites, which may help narrow down the comparison between the Celeron D
and a full-fledged Pentium 4.

Subject: [PCBUILD] Celeron Dprocessor requirements
I have a doubt: will the Celeron 2.4 GHZ Dprocessors fit and work in a mobo
formerly working with a Celeron 2.4 GHZ processor?
Will the mobo detect it as a P4?
is its performance comparable to a P4 letīs say 2 ghz?
