Notebook for a girl,

Looking for notebook below RM3, 000 (range 2,500 - 3,000)

Lady use, prefer :

Light weight
Efficient to dissipate heat
For studies only (non technical)

SSD - 500gb (or either 250gb)
Windows 10
RAM - 16gb (enough?)

Can ask, what's between Intel core 8th vs core 10th?
Intel or AMD doesn't matter. (right?)
Wanna ask... What's the best display size 13", 14" or 15"
Prefer non touch display. Or touch better?

Please help to recommend. Tqvm ya gaiss....
