Single core vs Multiple core

[sai97]

Is it better to run a device on a single core or to run in a multiple core. Will it have any change in my power utilization and working speeds. I basically use my laptop(dell inspiron 7559 i7) for CAED modelling and mediocre  games like Arkham Knight and Witcher 3 .

yes its better to get a multi core system. i dont think anything modern can work on a single core system, let alone playing games and CAD modeling.

it will change in working speeds, in a negative way. single core will make the system lag and it will slow down whenever you're doing something in the background.

CPU? set affinity? what exactly do you mean?

[sai97]

I am asking whether  is it useful to change it to run in all 8 hyperthreaded 4 cores or else just 1 core

there was a transitional period where this actually did matter. not so sure it does any more......... maybe pre 2008 software once in a while?

Why not just benchmark it if you care so much?
