That'd be MHz, and no, it's not where the performance rating is derived
from. It's quite an easy matter to google this.

No, he's saying it doesn't utilise it at all. It's written to use a
single core/single CPU, and that's all it will use.

Only one core is running the application, yes.

You really need to do some reading as to what the 3600+ really means.
It'll explain to you why you may be in error here, too. Speed in GHz is
no longer a valid measure of CPU performance. CPUs are changing, and the
refinements in how they work are what is brining performance up more
than just raw speed. Use benchmarks to compare CPUs now, not GHz.

Have a look at how your new CPU compares to your old CPU in gaming
benchmarks. There are too many other factors, such as RAM type and
speed, motherboard, etc, to make the conclusion you're heading towards.
