Laptop shopping has always been a very tedious job. The sheer number of options available in the market coupled with the long list of laptop specifications makes it a tough job for a user to find the most suitable one. The advancing technology has led to newer innovations which has caused an uproar among users when they are trying to buy laptop online.
Check out the five common queries addressed here to solve the issues experienced by users when buying laptops:

What is better : dual-core or quad-core processor?
The dual core processor is the one that comes with two processing cores, while the quad-core has four processing cores. To be precise, the number of processing cores determine the number of programs that can be run on a particular computer. So, a computer having a processor with more number of cores will allow users to run more programs at the same time. This is mostly true for content creation softwares such as 3D modelling or even video editing tools which need additional processor cores. In such a case, the quad core processor would be a better option as it will run faster than the dual-core version.
Although it is preferable to buy laptops online that have processors with more cores, the dual-core chip is considered to be adequate for an average user. The processing cores are mostly required for running high-end games and content creation models. So, the quad core processors are usually opted by gamers and content creation industry. It is known that quad-core processors are expensive, but it is also possible that it can become warmer and reduce the battery life of the laptop.
How much RAM is needed?
RAM is nothing but computer memory which is used by CPU to store data and programs. The optional memory to RAM is hard disk (HDD) which stores data when RAM is not enough. Usually, RAM is depicted as a work table that is full of data that is currently needed by the CPU. In such a case, the HDD poses as a bookshelf as it is quite slower than RAM.
It is evident that insufficient RAM can cause the CPU to stay idle for longer time till the data is being fetched from the hard disk. Instead, it is desirable to have ample RAM storage that can save on lots of processing time and deliver better.
The amount of RAM storage required by a particular computer is solely dependent on the operating system being used in it. It is evident that a 32-bit OS can access only 4 GB of memory which includes even the graphics card. Technically, a 64-bit OS can use almost 16 exabytes though Windows 8 is capped at 512 GB for Pro version and 128 GB for standard version.
Usually, a 4 GB RAM is adequate for a laptop that runs on a 32-bit OS while laptops using a 64-bit OS should have RAM of 4 GB or more. This is the reason for most laptops to come with a minimum of 4 GB RAM though there are some latest laptops that have 6 GB or even 8 GB of RAM.
People who need to run programs that use large amounts of data need to opt for higher RAM storage. The laptop size becomes a big constraint due to which they offer a maximum of 32 GB for highest-end models.

Is it necessary to upgrade to discrete graphics?

Most of the modern laptops have CPUs with integrated graphics which means the built-in processing elements they have render the display screen of the notebook. Even though integrated graphics have improved and allow the users to play 1080p videos, they are still not ideal for gaming.
There are some games that can be run by using integrated graphics though it is not recommended to do so. The best way to ensure that the users can play the latest games would be to get a discrete graphics chip from AMD or Nvidia.
Even though the discrete graphics chip enables users to play games, it drains the laptop battery faster and needs extra cooling. The extra cooling kit leads to a bulkier chassis on the laptop.
Is it preferable to get an SSD storage?
The solid-state drives, also known as SSDs work on the NAND Flash technology which is used in thumb drives. The SSD drives are known to be faster than the normal mechanical hard drives. They are also more durable and resistant to drops.
Even though the SSD prices have dropped significantly, it still remains more expensive than the hard disk drives (HDD). Yet, it is preferable to opt for an SSD which can boost the laptop’s performance as it works as the biggest upgrade for it. It boosts performance far more than that achieved by switching to quad core processor or upgrading RAM.
The only glitch with this is that SSD gives storage space of approximately 512 GB which is limited when compared to HDDs that can go up to terabytes. The best option would be to store most of the data on an external hard disk and use the SSD only for the regularly used apps and data.

Does screen resolution play a major role?
The screen resolution of a laptop depicts the number of pixels that can be seen on the display. The pixels are nothing but small circular dots that fill up the screen of the laptop. When all the pixels are combined together, they form an image on the screen. Usually, the typical resolution of 1,366 x 768 pixels depicts that the screen has 1,366 pixels for width and 768 pixels for height.
In order to get a better looking screen, it is preferable to increase the number of pixels on the fixed screen size. It is a bit difficult to fit more pixels into the same area as they will have to be smaller giving smoother and sharper images. So, the screen resolution is always coupled with the size of the screen.
The pixel density is determined by combining the screen resolution and screen size and is denoted as the number of pixels per inch (PPI). So, it is preferable to have a laptop with high pixel density as it gives a sharper screen that looks better. A great example would be Apple’s 13.3-inch MacBook Pro with Retina Display which has 2,880 x 1,800 pixels screen resolution with 220.5 pixel density.
Although it always proves useful to know about pixel density and screen resolution, it is usually the user’s preference that matters. So, it maybe possible that some users prefer lower resolution screen while there are others who might find jagged edges unacceptable. Apart from pixel density, there are many more factors that contribute towards screen quality including viewing angles and accuracy of colour reproduction.
