[fpc-pascal] Will moving from due core CPU to 6 Core CPU of the same clock speed improve the speed of FPC compiling?

[Dennis]

I have been using Intel i3 Dual Core CPU @3.4 GHz for a few years.
If I upgrade my computer and CPU to Intel Core i5 6-core @3.6GHz,
will the speed of FPC compilation improve noticeably?

Since FPC seems to be single threaded, I wonder whether 0.2GHz increase 
in clock speed will make any noticeable improvement in speed.
