When looking for a new laptop, the processor is one of the most critical specifications. Here’s what you need to know about them:

The processor is the brain of the laptop. It determines how fast your computer can run and how many tasks it can handle simultaneously.

Processors are ranked by their clock speed. The higher the number, the faster the processor. However, other factors, such as the type of chip and the amount of cache memory, also affect performance.

Some processing units are designed to perform specific tasks, such as graphics rendering or game development. If you know what you will be using your laptop for, look for a specifically tailored processor for those activities.

Not all processors are alike. Some are more powerful than others, and some have even greater functionalities. Be sure to compare different processors before making your decision.


Most processors have multiple cores. A core is simply another processor on the chip. Dual-core processors feature two cores, and quad-core processors feature four cores. It performs the calculations and instructions that make your computer work. In light of your desktop computer having more cores, it can complete more tasks simultaneously, thus working more quickly.

So when you’re looking at processors, be sure to check how many cores it has.

Quad-Core vs. Dual Core: Which is more suitable?

Dual-core processors can easily handle basic tasks like web browsing and email. They also use less power, which is excellent for devices that need to be portable. Quad-core processors are ideal for more laborious tasks, such as video gaming and editing. They also tend to use more power, so they may not be ideal for devices that need to be battery-powered. 

If you’re looking for a device that can do basic tasks well, go with a dual-core processor.

What is Turbo Boost

Turbo Boost is a technology used by Intel processors that allows for a temporary increase in the processor’s clock speed. It can be helpful for tasks that require more processing power, such as gaming or video editing.

Core i3

The Core i3 is the entry-level processor and 2 cores. It has decent performance for basic web browsing and word processing tasks. It doesn’t have as many features as the higher-end processors, but it’s a good option for budget-minded buyers. 

Core i5

The Core i5 is an excellent all-around processor and 2 or 4 cores. It has better performance than the Core i3 and more features than the Core i3. It is a wise option for people who need a versatile processor to handle different tasks.

Core i7

The Core i7 is the most potent processor Intel offers and 2-8 cores. It was developed for professional gamers, video editors, and other power users who require the best image quality possible.

What do the 6600, 7700, 7500, and 7200 numbers mean?

The first number, 6600, 7700, 7500, or 7200, is the processor’s model number. The more influential the ability is, the higher the number is.

The second number is SKU (stock keeping unit) numeric digit means nothing in and of itself. It is simply a unique identifier for a product.

The last number is usually just a suffix and doesn’t have a specific meaning. It may indicate that the processor is designed for use in a laptop or mobile device or a low-power version of a more powerful chip.

Ram, also known as Random Access Memory, is vital for any laptop. It allows your computer to keep track of what is open and running at any given time. When buying a laptop, it is essential to understand the different specifications associated with the ram. 

The first specification to look at is the type of ram. There are five types: DDR1, DDR2, DDR3, DDR4, and DDR5. 

DDR1 and DDR2

DDR1 and DDR2 have been with us and are slowly being phased out. They are both relatively slow and can only handle up to 128 Mb (Here, there were no modules with more than 1 GB.) and 256 MB (Here, 2 GB per module).


The third type of RAM, DDR3, is much faster than the first two and can handle up to 8GB of data. It is commonly used in laptops today.


The fourth type of RAM, DDR4, is even faster than DDR3 and can handle up to 64GB of data per module. The second specification to look at is the speed of the ram. This can be measured in megahertz, or gigahertz can be indicated. The larger the number, the faster the memory will be. Therefore DDR4 Ram speed starts from 2400MHz to 3600MHz.


DDR5 is the next primary memory standard, thanks to its improved performance and lower power requirements. DDR4 is great, but DDR5 has the potential to completely change the gaming landscape. DDR5 also offers some terrific advantages over DDR4, such as higher bandwidth and excellent compatibility.

DDR5 memory is a new type of memory developed by Intel and Samsung. DDR5 can run at speeds of up to 4800 to 7200 MHz. DDR5 also can support more than two billion operations per second. This makes DDR5 the fastest type of memory currently available.

RAM Technologies

SDRAM, or synchronous DRAM, was the first type of RAM used in laptops. It is still used in some laptops today because it is cheap and provides enough memory for basic tasks. However, SDRAM is not as fast as other types of RAM and can’t handle as many processes at once. 

LP or low-power RAM is a newer type of RAM that uses less power than SDRAM. This makes it ideal for laptops that need to stay powered on for long periods. LP RAM also runs more excellent than other types of RAM, making it a good choice for laptops that get hot quickly.

Storage Device

There are two types of storage devices- hard disk drives (HDD) and solid-state drives (SDD). HDDs use spinning disks to store data, while SDDs use flash memory much faster. An HDD will be fine for most people, but if you plan to do a lot of video editing or need faster boot times, go with an SDD. 

eMMC(Embedded Multimedia Card): 

An embedded Multimedia Card (eMMC) is a storage device used in portable electronic devices, such as smartphones and tablets. The eMMC is a smaller alternative to the traditional solid-state drive (SSD). It offers faster read and writing speeds than an SSD, but it is also less durable.

Which one should you buy? 

That depends on your needs and budget. If you need a fast and reliable laptop, go with an SSD.

Another possibility is a hybrid hard drive with a solid-state drive. This gives you the best of both worlds: fast read and writes speeds from the SSD combined with large storage capacity from the HDD.


1080p (also called full HD) is the standard resolution for most laptops these days, and it provides good image quality. If you want something even better, you can go with Quad HD or 4K, but keep in mind that those resolutions will require more powerful hardware and may not be available on all laptops.

Second, consider how the laptop will be used. If you need portability, consider getting a smaller screen size model.

IPS display

IPS displays offer wider viewing angles than TN displays, making it easier for more people to see the display. They also offer better color reproduction and contrast ratios, resulting in a more pleasing picture. 

UWVA Brightview

UWVA Brightview displays offer even wider viewing angles than IPS displays, making them excellent for group settings.


WLED-backlit displays provide significantly better power efficiency and brightness than CCFL-backlit displays. 

Retina Displays

Retina Displays have a very high pixel density, resulting in incredibly sharp images. 

Glossy displays

Glossy displays produce brighter and more vibrant colors than matte displays.

Graphics Card


Graphics cards are an essential part of a laptop. They come in three types: integrated, dedicated, and vRAM. 

Integrated graphics cards

Integrated graphics cards are the weakest type and are integrated into the motherboard.

Dedicated graphics cards

Dedicated graphics cards are much more robust and have their chip. 


vRAM is a new graphics card that is even stronger than dedicated cards. It can work faster than other machines due to its sizable memory storage space.

When choosing a graphics card, you should consider your laptop’s power and what you will be using it for. If you need a powerful card for gaming or video editing, you should choose a dedicated or vRAM card. An integrated card will be fine if you only need something essential for surfing the web or watching movies.



Make sure the laptop you’re considering has the ports you need. If you want to connect an external hard drive or printer to the laptop, make sure the computer has USB ports. If you want to be able to connect your computer to a TV, look for one with an HDMI port.


This is an older port that connects laptops to projectors or older TVs. Most new laptops don’t have VGA ports, so if this is something you need, make sure to double-check before buying.


This is the most common port for connecting laptops to TVs.

USB 3.0

This port is used for transmitting data and can transfer up to 5 Gbit/s. It is also backward compatible with USB 2.0 gadgets.

RJ-45 Ethernet Port

This port is used for networking and can reach speeds of up to 1 Gbps. 

Thunderbolt Port

This port is used for data transfer, video output, and charging devices. It can reach speeds of up to 40 Gbps.

SDXC Card Reader: 

This port is used for reading and writing SDXC cards. 

Mini DisplayPort: 

This port is used for video output and can connect to displays with a Mini DisplayPort connection.


One of the most common types of connectivity is BlueTooth. You can connect to other devices wirelessly, such as headphones or a mouse. This option allows you to be untied to your device by wires.

Another common type of connectivity is 802.11 A-C and 802.11 bgn. A wireless connection typically allows you to access the Internet. The main difference is that 802.11 A-C offers faster speeds than 802.11 b/g/n.

Even, The laptop also has 6th gen wifi chipsets, and laptops are starting to come with built-in support for 802.11ax. This new standard can create significantly more network interference than the older 5Ghz frequencies, so if you’re looking to buy a laptop in the near future that supports 802.11ax, be aware that there may not be many options available.
