Identifying genuine core i5(new generation) laptops

[Harleystephen43]

I bought a used hp 650 core i5 laptop only to find out that it was an upgraded laptop(I.e an old generation laptop whose processor was upgraded). So I want to know how to identify a genuine core i3, i5, i7 laptop. By genuine i mean it should have all functionality of new generation laptops, not just the processing speed of core series laptops.

The HP 650 goes back quite a few years. It is able to use up to an i3-2370M CPU. This is an i3 processor and perhaps an i5 from the same generation (2d) could be installed and used. But the current most recent generation of the Intel Core processors are 10th gen and most laptops for sale in stores and the internet as new are at least 8th generation Intel Core processors. Whenever I see laptops advertised, the processor is generally one of the things prominently mentioned. What is it you need to do with your laptop? We can certainly help you figure out the processors installed in any specific model you may be looking at. 

Don't settle for just knowing it is an i3 or i5 or i7; you need to know the exact processor type installed so its capabilities can be compared.

I don't know much about laptop but I need the one that will allow me multitask without slowing down in terms of speed. And it should not be upgraded laptops.(I.e older generation laptops)

I am not really clear where you bought the 650 or how it was marketed to you. I see you are in Nigeria and I am not familiar with your purchasing options. What is your budget for a new laptop?

$250. If I could get a list of some laptops that are resent generation I'd appreciate it

This whole website sells laptops. You will not find much with an Intel Core for $250 I fear. You might want to consider refurbished or a newer used laptop.

A newer used laptop we be good. Any recommendation? As per website for purchase or a model.
