Really quick quest about processors. (PC)

[Sicarius]

Would a 1.5 dual core processor run better, similar, or worse than a computer with a 2.20GHz single core processor?

I -think- the formula is

cores*ghz

so, using that formula, the 1.5 processor is faster as long as you use the extra cores.

I -think- the formula isso, using that formula, the 1.5 processor is faster as long as you use the extra cores.

that's the formula I use

No, it's just two cores working at 1.5 GHz.  They're near equal.

Just for future reference, that formula is incorrect.

No, it's just two cores working at 1.5 GHz.  They're near equal.

Would only benefit programs and games that support more than one core, otherwise you're effectively running 1.5GHz single core.

Also, speed isn't the only thing that matters. Architecture matters too. What models are they? For instance, a cruddy Athlon single core 2.2GHz is way worse than a Core 2 Duo 1.5GHz.

Saw that coming.
Anyways, what is the 'formula' if there is one?

There isn't really one.
The best way to think about it is that there is 2 processors working at 1.5GHz instead of a single at 3GHz. They don't add together, they divide work between themselves. It would be similar to the formula you used, but only for multithreaded applications.

Those are really terrible processors.
