CPU cores for testing mt4

 
Dose more cores helps to do testing fast?
I have i7 4790k which has 4cores at 4.0 ghz with 16gb ram. It shows 700hrs for testing for 10yrs data on one pair. Will a CPU with more cores help reduce the timeing for this test? Or this is the max speed I will get with even 8 or 10 cores CPU?
 
If you had used this you would know that MT4 uses one core only.

Hi,

And on a single core basis how much faster could we backtest on mt4 if we switch from i7 4700-HQ to i9-9900K for example ?
