Obviously, and though Hardware is a very important feature to consider when buying a laptop, there are other factors you may want to consider, such as screen size, that light is able to move you from one place to another, etc. Those things are your choice, because they will depend on what you need.
For example buying a laptop for gaming is no different unusual from your site and where your dedicated artwork is more important than weight and size, the one who intends to take you on an endless journey because in this case you will be interested in light and gain good battery life.
The processor is the brain of the machine, so it's certainly one of the most important things to consider when buying a laptop. It goes without saying that portable processors want to have low usage to improve battery independence and do not require cooling systems as big as desktop PCs, and yet we can get powerful portable controllers. good performance
Depending on your needs, with a "dual core" processor it may be sufficient, although it is very common today for all types of applications (including games) quad core processors. In any case, you should carefully consider which processor is best equipped for the laptop because it is very common to integrate it HyperThreading or SMT technology of these. In other words, two basic processors may appear to have four parallel threads at once, being "equal" to non-core quad core processors.
To check how many cores and threads a processor has, we recommend that you find them on the manufacturer's website (Intel or AMD). If the manufacturer tells you that it has an Intel Core i5 processor it won't tell you much, but if you look at the processor on the manufacturer's website you will find all the details.
As a general rule, and unless you use a laptop for professional or editing purposes, The amount of RAM to look for is 8 GB. Today 4 GB will be enough, so don't think about it, and 16 GB might be worth it if you're going to use heavy equipment and games, but again, 8 GB is a valid number for a large number of users.
Running away from laptops with non-4 RAM values (8, 16, 32, 64 …) because in that case either using RAM is sold on board or using different modules, which can eventually lead to problems. Unfortunately, it is common to see manufacturers that want to sell you a laptop with 12 GB of RAM, and that usually has 4 GB soldiers at the plate
Depending on what you are going to use for the laptop, integrated graphics may be important or not. Obviously if you want to use a laptop for gaming you will need to search for AMD or NVIDIA graphic on your laptop, which will greatly increase its price. But if this is not the case, with the integrated graphics coming to the processor you will have everything, even simple games if you intend to play occasionally.
Don't warm your head: if you can't play (or give a video, etc.), a composite image will do its job well in a variety of areas.
Today it doesn't make much sense to buy a laptop without an SSD, so the recommendation is that if the laptop has a regular hard drive, don't consider your purchase because you will know that it is slow from day one. Even those laptops with the SATA 3 SSD will give you the best performance and power times, so the recommendation here is to keep an eye on options with SSDs
Whether SSD is more or less powerful, whether it is SATA or NVMe will depend on what you need and what you want to use, but always choose SSD.
Note the screen resolution
In the end, screen adjustment is also a factor to consider. Some manufacturers are still selling (or rather intending to get them out) laptops with screens resolution 1366 x 768, and it's something to avoid. This decision is very low, and today many web pages are made for full HD resolution. We're not talking about games or if you want to watch a series on Netflix.
We also have the opposite selection, which manufacturers want to sell 4K screens. Why? With the screen size you have on laptops, 4K resolution doesn't make sense unless you're a professional. In addition, and especially for laptops that use integrated graphics, this will make everything slower because most system resources will be "deployed" to be able to deploy that decision.
Our recommendation is to keep an eye on it Full HD resolution screens.
