The difference is night and day. An i3 is slow. We have NO i3 machines at clients. i5 high end is excellent and of course, i7 for a price is excellent. I have an i7 on my ThinkPad X1 machine. I have an i5 on my ThinkCenter Desktop at home and it is plenty fast.

If you can spring for an i7, do it. If a high end i5 fits your budget, that will be fine. Stay away from i3.

Beware that some machines need i7 for 16 GB of memory. My ThinkPad X230 had an i5 with 16 GB but my new X1 must have an i7 or it is limited to 8 GB.

An i7 CPU will give you a noticeable boost in CPU speed. Overall speed is dependent of other factors, also what you are using the machine for. Before looking at an i7, for "general" "office work" under Windows, make sure you have an SSD and at least 8Gb of ram.  If you play video intensive games, make sure you have a discreet, gaming orientated video card.  

The downsides of going for an i7 are increased cost, increased heat, shorter battery life, increased noise, and increased weight.

An i7 is about 20% faster than a high end i5 according to benchmarks I looked at. So you have to spend the extra deliberately.

I have a PCI-e NVM-e SSD card and it is faster than SATA, again at a price.

A 7200-rpm hard drive is not speedy but it will do yeoman service. My X230 above has a 500 GB 7200-rpm hard drive.

i5 high end model means what other parameters i have to check. i have one other laptop that is i5 which is 17 inch bit big one which i do not use often

i7 16 GB large PCI-e SSD drive is NOT a budget model.

Budget model means i5 8 GB and a hard drive (to have decent space).

You need to understand what Games. Some need an i7 and SSD but as I said that is not cheap and not budget.

Your wants and costs are colliding.

My X230 was a super machine and not noisy. 3 - 4 hour battery life.

My X1 is quiet, super fast start up (30 seconds to fully start) and 6 - 7 hour battery life.

Depends on the laptop. The maximum on my X1 is 16 GB. 8 GB suffices for almost all usage. I want to run multiple machines at the same time and virtual machines chew up memory. That is why I have 16 Gb.

Windows 10 and its related software runs happily in 3 GB. 8 GB provides headroom and 16 GB will not add speed.

You can try C|Net but I use manufacturer's site. The comparisons are not always apples and apples, so be prepared to keep your own record of important points.

Laptops that run a Xeon CPU, 64GB of RAM and a RAID array exist, with a price tag similar to a small car. Gets a bit impractical though.  

16Gb of RAM will only be useful if you are running atypically memory hungry applications, like virtualising several machines at once.

i have a desktop i-7 with 16 GB ram, and found it not faster than my previous i-5 system with 8 GB ram, for normal use
imo - you'll see noticeable differences only with high cpu loads

Hi.
"any cheap and best laptops with good configuration" - cheap and best - haha. So you are willing to invest how much ins US$?
To find out, what your laptop is lacking (CPU power, amount of RAM, hard drive speed), we would need info on resource consumption while the slowness shows. This can be read out by resource monitor which you can start from task manager. Do you feel fit to provide these details?

I7 CPU (just the CPU) is about $500. The computer is on top of that.

how do we measure laptop performance to find is it optimal or not?

There is no such think as an optimal CPU.   i7 is faster than high end i5 is faster than low end i5 is faster (much faster) than i3.

I have been using the fastest i5 Lenovo would supply on any give desktop or laptop and that has serviced me well. The X230 I mentioned above is a fine machine. Works great, is fast when running, has hard drive, takes 5 minutes to fully start and is now my spare. It is in its fourth year and I wanted a new machine and a decent spare.

The X1 Carbon comes high end i5 or i7. You need to fork out for i7 to get 16 GB of memory, which I use. Between the i7 and fast CPU it is a very fast machine.

Instead of optimal, you need to look at load. Simple games and most everything else will run on an i5. High end games need an i7 and high end graphics. I do not run such games.

"how do we measure laptop performance to find is it optimal or not?" - I told you twice that I suggest to use resource monitor.
So while your machine acts slow, resmon can record how many resources are in use.
To start it, just press windows key and r together and there, at the prompt, type
resmon

At your price point, the systems will be cheap and slow. I do not see a point on you trying to buy a new machine until you can save some more money toward it.

A MAC similarly configured as a good Windows laptop will be about the same price.  Cheaper ones are fine for Apple Quality but will have a slower CPU, less memory, and a smaller SSD drive
