A laptop is already very portable so to a large extent, the processor is not considered very important. There are laptops that do not have any and others that have even an old clunker sitting alongside them with no issue. Here is a simple way to tell a difference between a normal CPU and an Intel Core i7 in a laptop: Figure out if your computer wants to POST when you power on it. Same like How do Laptop Cooling Pads Work

If it does, then that is perfect. The majority of Intel Core i7 laptops will do just fine without one unless you want something more advanced then you can always buy another desktop computer later on! Pentium 4 3.2um processors are rather slow too but if yours were the starting one you would use anyway to build up machines then those are perfectly good for garage PC builds. See how far you can get with switching processor(s) Suits A basic budget user who needs limited performance and wait for things to slowly trickle through Convert as many video formats as possible without having issues Despite limited Read and write speed, Quad-core applications generally perform well. High on enthusiast list.
What is the Best Processor to Have?
The best processor to have depends on many factors. If you are looking for a fast machine, you would opt for a high-end processor. looking for a cheap and good value, then the support from an Intel Core i3 or i5 is good enough. If you are looking for something in between, then the choice is yours to make. Overall, the processor you have at home is not going to be very impressing nor important. One thing we can recommend though is to check out what this makes your computer do. A motherboard with a dual-core processor will perform the same as a quad-core processor but it will work slower and has smaller memory capacity. If you need more memory, look into upgrading that first and if you are still lacking then consider getting a processor upgrade in the wider range of options that is available
How do I Know Which CPU to Get?
It all depends on your budget, how much power your want and what use you intend on putting this computer to.
For Gaming

An Intel i5 4690 or AMD FX-8350 processors are great for most games like League of Legends or Call of Duty Black Ops 3 . The i5 4690k will give a higher boost but the FX 8350 hits the speed ceiling which makes it an excellent choice for gamers. If you are looking for great value, a Phenom II x4 965 will hit the same figures as the FX-8350 but at a lower cost and is much more efficient for gaming.
For General Use
If a program needs such high processing power, then go for the Intel i7 5960x. It is extremely fast and can be an improvement over regular i5 processors when it comes to things like multi-tasking and power consumption. Likewise, if you need extra memory for your programs and want to multitask efficiently, then an i7 6920x will be the solution.
For Video Editing

If video editing is a priority on your list, then go with a Core i7 7740k or any of the others in that range including the 7700k and 7700. The 7740k has a higher turbo frequency than other processors in that range so you’re getting more power out of this one. If you go for a higher-speed processor, then you might need to upgrade your motherboard first.
Conclusion
In the end, it is all about your budget and the use you intend on putting it to. However, if you are a gamer then your best bet would be an i5 4690k. The device runs cooler than an i7 5960x and has more memory than an i7 6920x.
