i am trying to compare between single core 3.4GHz and dual core 1.8GHz processor.i hv the idea there is no definite answer to this...but which one is faster? how is the best way the two processors

What are the models? Its not really about GHz, Dual core, single core, quad core and so on.

Most of the time a dual will be better. But we would need to know what models they are to check whats better.

Its more about how they were built.

Just going by the way technology has gone, the dual-core is most likely faster then the single-core. Since the Pentium 4 / Athlon 64's, very few single cores were faster then the dual-core's being released at the time, regardless of Ghz.

Neither, they will both be atrocious. I don't care what you are trying to do, a single core @ 3.4 GHz is likely a Prescott P4 and a Dual core @ 1.8 is probably an Atom D525, you don't want either. Its likely not a Core 2 or a Nehalem based chip as they would come in at 1.86 GHz

In the hypothetical scenario: If you had a dual core, and a single core, that are identical up to the physical core count... neither one would really be better than the other, unless you gave a specific scenario. Certain tasks would benefit from splitting the load across two cores, while others won't. Some tasks don't even use enough resources to yield a noticeable difference.

If you are trying to compare CPUs that have been sold, then knowing which CPUs you are comparing would help immensely.

Both Pentium 4 and Core2duo would fit and function inside of an LGA775 motherboard making it the most likely two processors being compared. The above Core2duo is almost certainly the one being looked at as it is the only Core2duo that runs at 1.8Ghz even and also is made for LGA775.

In addition, Atom is available as integrated units, and thus not able to be changed making it very unlikely to be the one asked about.
As for performance, while it wouldn't be good for gaming my work still uses systems with 1.8Ghz and 1.87Ghz Core2duo CPUs and they work fine for office work and web browsing. Its still a viable option at a very low cost for a basic system.

Depends on what you are doing. Generally you will not notice a performance difference between the 2 when single core tasks are done, there may be some exceptions on certain low end cpus. Dual cores will be better if you are doing multi thread tasks as the number of cores makes a difference..
