Your link helped me narrow down at least one likely candidate.
The original question probably relates to some Joy Systems
refurbished off-lease machines. And the dual in that case
could be an E2200.

On single threaded

Intel Pentium E2200 @ 2.20GHz 798
Intel Pentium Extreme Edition 955 @ 3.46GHz 796

The IPC of the first processor, is about 1.5x the second
processor. Which is why the E2200 at 2.2GHz can do the
same amount of work as a P4 class processor at 3.46GHz.

That means the E2200 is like two Pentium 4 CPUs in a single socket.

On multi-threaded. the E2200 wins against its Hyperthreaded opponent.

Intel Pentium E2200 @ 2.20GHz 1203
Intel Pentium Extreme Edition 955 @ 3.46GHz 905

The E2200 will also support more OS possibilities and
meet more software requirements.

Where they differ, is it's possible for a Pentium 4 era CPU
to be better at floating point. But that's not normally
separately benchmarked for our enjoyment. So that remains
a research topic. The IPC factor of 1.5x applies to integer
code, and integer code dominates a lot of user activity
(but not all of it). As soon as a say that, somebody will only
run off and find some FPU-only code for me to test :-)
