Question related to Single and Multi Core

Most applications today use just one core of the CPU like older games and some software etc. So if an application cannot use the processing power of all the cores and uses just one core then will an old Pentium processor @ 3 GHz run that program faster than a i7 @ 2.2 GHz?

Remember I'm talking about an application that is built to use just one core of the processor. Of course the i7 is faster but using only one core will the old Pentium processor be faster in running that program?

Can you mention the app's name ??

BTW, a app ( even if it uses single core only ) will perform much faster on a core i7 @ 2.2 Ghz.

Single core Pentium 4 running at 3.0 Ghz was not even faster than single core AMD Athlon 64 2.0 Ghz of that era.

Forget about the current processors.

Here is an example: (lower time is better)

Athlon 64 3500+ ran at 2.2 Ghz. 3200+ and 3000+ ran at 2.0 Ghz. 2800+ at 1.8 Ghz.

Pentium 4 clock speeds are mentioned.
