Does quad core is better than dual core for running multiple application each app doesn’t support multithreading?

Question

I have heard that in order to utilize multiple cores the application should design to support multiple threading

But what if applications are multiple, each application doesn’t support multithreading then in that situation dose multiple core is better than single core or not ? example MS Word, Skype, VLC Player, Avira, AVG and I am assuming each of this app doesn’t support multithreading and running parallel

Dual Core i5-6200U vs Quad Core i7-6700HQ

Does my battery will drain faster if I use quad core instead of dual core ?

Answer 1

Multithreading support helps improve the performance of some programs, by letting the programs distribute their workload among many cores. However, even if you don't have a lot of multithreaded programs, it's still useful to have multicores, simply because all modern day versions of Windows are multitasking, i.e. running many separate programs all at once. Windows can distribute each of the programs around separate cores too, so there is still an advantage you can gain.

Answer 2

If you have a core dedicated to the operating system, a core dedicated to your application, then you have two additional cores to process data online, or run a media player in the background. Also quite of a few of those applications support multi core processing. The only thing I can think of that doesn't utilize multi-core usage is VP9 encoding.

Answer 3

you need single core buddy.
