4gb is bad, but to quantify – my son’s i3
Depends on the age/version of the processor.
Case in point, I recently bought an emergency replacement laptop for £400, latest gen i3 and fast 4gb ram… 128gb SSD not my first choice of spec but I had a budget and I had to have it next day.
It is very quick and responsive, in terms of general internetting, VPN, RDP, watching films etc.
I can tell it struggles a little when mulititasking – loads of apps open etc, but it’s actually really supprised me.
I’ve set it up very clean and light though, firefox with Ublock origin, removed the crapware that came whith it, minimal start up apps etc.
