Laptop buying guide: how to choose the right computer for your next computer

Choosing a laptop these days can be a real headache: there are hundreds of models, technical specifications full of acronyms, and a lot of marketing that doesn't always help. Take some time to understand what you need and what each component actually offers. It makes the difference between getting it right the first time or ending up with a team that falls short after a few months.

In this buying guide you will find everything you need to know to make an informed decision: What to look for when buying a laptop, which components are key depending on your use, which processor and graphics card ranges suit you, and what screen size is most comfortable. for work, study, play or travel, and also practical advice on battery, connectivity, stores to buy from and brands worth trusting.

First step: define what you want the laptop for.

Before talking about processors, RAM, or graphics cards, the wisest thing to do is to stop for a moment and ask the big question: "What am I really going to use the laptop for?"It seems obvious, but many people buy thinking "just in case" and end up paying more for power they will never use.

We can group the uses into three main categories: Content consumption (browsing, series, basic office tasks), light content creation (studies, office work, moderate editing) and demanding creation (video, 3D, gaming, heavy programming, AI, etc.). Each group needs a different type of machine.

If you just want something simple for internet, email, and video, You don't need a high-end laptop with a dedicated graphics card or 32 GB of RAMHowever, if you plan to edit 4K video or play modern AAA titles, buying very basic equipment will be a continuous source of frustration.

Therefore, the first filter you should apply is this: consume vs create vs create “like the beast”From there, you'll see that everything else makes more sense and you won't be swayed solely by price or design.

Types of equipment according to use: consuming or creating content

When the primary use is consuming content—browsing, video, social media, simple documents—it's important to be clear that You don't need a "bulky" laptop with Windows and high-end hardwareIn many cases, you're paying for compatibility and power that you never get to use.

Several alternatives fit this scenario very well: Chromebook (ChromeOS), tablet with keyboard and mouse Or a lightweight, simple Windows laptop, nothing fancy. Each has its advantages and limitations, but all are perfectly adequate for basic use.

However, if your goal is to create content in a more or less serious way —photo editing, video, audio, programming, design, 3D, gaming— the picture changes completely: Here, the processor, graphics card, RAM, type of hard drive, and above all, cooling, become extremely important.It's not enough for the equipment to be "fast" for the first five minutes; it needs to maintain that level for hours without any drop in performance.

In the field of creation, there are two very clear branches: lightweight laptops geared towards productivity and creativity (such as ultrabooks or MacBooks)and larger gaming or workstation-type machines, designed to provide sustained power and push the GPU to its limits with fewer thermal restrictions.

Key aspects to consider when buying a laptop

Once the use is clear, it's time to get down to the technical details. Processor, RAM, graphics card, storage, screen, battery, and connections These are the pillars that will determine the performance and lifespan of your equipment.

It's not about always going for the most expensive option, but about understanding what each element contributes: A weak processor or insufficient RAM can make a new laptop slow from day one.And an inadequate graphics card can hinder both games and certain professional applications or AI tasks.

Processor (CPU): the brain of the laptop

The processor is responsible for executing almost everything you do on the computer. It is one of the components that most influence the overall feeling of flow and, at the same time, one of the things that makes the equipment the most expensive.

Currently, three families are mainly in charge: Intel Core (i3, i5, i7, i9 and Core Ultra in the new nomenclature), AMD Ryzen (3, 5, 7, 9 and Ryzen AI) and Apple Silicon chips (M1, M2, M3, M4) in the case of MacBooks. Qualcomm is also starting to gain traction with its Snapdragon X processors in ultralight Windows-based ARM devices.

On classic Windows laptops, you can find guidance like this: An i3 or Ryzen 3 is suitable for office work and light use, while an i5 or Ryzen 5 is the sweet spot for most users.An i7/i9 or Ryzen 7/9 is designed for gaming, video editing, 3D modeling, or very demanding workloads. At Apple, even the entry-level M1/M2 processors offer respectable performance for general use, while the M3/M4 raise the bar for professional tasks.

In addition to the processor "family", it's worth noting the letters in the model (the suffix): The U and Y series prioritize efficiency (better battery), while the P series balances performance and power consumption. And the H or HX ranges focus on maximum performance, very common in gaming laptops and workstations.

RAM: Multitasking and the future of the computer

RAM is the memory that the system uses to keep the applications you are using open and running smoothly. The more RAM, the better the laptop performs with many tabs, programs, or heavy projects.and the jerking will be less noticeable.

Today they are considered 4 GB is barely enough and only suitable for very basic uses8 GB as the reasonable minimum for browsing, office work and multimedia, and 16 GB as the ideal point for those who work with several apps, do some editing or play games with some enthusiasm.

For highly demanding profiles —professional video editing, 3D modeling, virtual machines, local AI, high-level gaming— 32 GB starts to make a lot of sense to avoid reaching the limit.Beyond that figure, it is only recommended for very specific and highly professional cases.

Another important detail is the type of memory: the DDR5 seeks maximum performance, while LPDDR5/LPDDR5X stands out for its lower power consumptionThese latter ones are usually soldered in ultrabooks and MacBooks: they consume less power and provide better battery life, but they cannot be expanded later, so you have to get the amount of RAM right from the start.

Graphics card (GPU): integrated or dedicated

The GPU handles everything visual: from moving the desktop to video games or rendering 3D scenes. If you're only going to write, browse the web, and watch TV series, a modern integrated graphics card is more than enough.Current integrated GPUs (Intel Xe, AMD Radeon integrated, Apple M, Snapdragon) handle high-resolution videos and basic tasks without problems.

If you want to play seriously, work with video editing programs, 3D, CAD/BIM, or AI tools that heavily utilize the GPU, A dedicated graphics card becomes practically mandatory.NVIDIA (GeForce RTX) and AMD (Radeon) dominate here, with a catalog ranging from modest models to true monsters for gaming and advanced work.

It's important to understand that in a laptop, a GPU "from the same series" as in a desktop computer It doesn't perform the same because the size, cooling, and power consumption are much more limited.That's why there are specific "Laptop" ranges with different power configurations (TGP), designed to balance performance, consumption and temperature.

The difference between integrated and dedicated graphics is important: The integrated graphics share memory with the RAM and consumes less power, but performs worse under heavy graphics loads.The dedicated graphics card has its own video memory (VRAM) and is designed to handle heavy loads, even if it means more heat, more noise, and a higher price.

Storage: SSD, HDD and recommended capacities

The disk is where the operating system, programs, and files are stored. Virtually all modern laptops now use SSD drivesmuch faster and quieter than the old mechanical hard drives (HDD).

SSDs can be SATA (cheaper and somewhat slower) or NVMe (mounted in M.2 format, with much higher speeds). For a modern laptop, a NVMe SSD drive as the main unit, since it greatly speeds up system startup and program opening.

Regarding capacity, 256 GB may be sufficient if you use little local storage, but it fills up faster than you might think. Today, it's recommended to start with 512 GB for comfortable general use.and upgrade to 1 TB if you're going to handle a lot of videos, high-resolution photos, heavy games, or large databases.

Mechanical hard drives have almost disappeared in new laptops; at most they are seen in very cheap computers or in desktops as a high-capacity add-on. If you need more space, an external SSD or the cloud can be a great help. without having to overpay for a model with much more internal storage.

Screen: size, resolution, panel and format

You're going to spend hours in front of the screen, so it's not a minor detail. Size influences both working comfort and portability.While resolution, panel type, and finish determine sharpness and color fidelity.

The most common sizes range from 13 to 17 inches. Between 13 and 14 inches you have very lightweight and easy-to-carry laptopsIdeal for travel and everyday use. The 15,6-inch screen is the classic middle ground: a good surface for working without sacrificing too much portability.

If you're barely going to take your computer out of the house or office and want a kind of "portable desktop", You can look at 16 or 17,3-inch models, which often even include a numeric keypad. and they provide more space for multitasking, editing, and gaming, at the cost of weight and volume.

In terms of resolution, Full HD (1920×1080) is the minimum reasonable standard today. For design, editing, intensive text use, or demanding gaming, higher resolutions such as 2K or 4K are recommended. They can be very useful, provided the GPU is up to the task. Higher resolutions mean more work for the graphics card and higher power consumption.

As for the panel, the most common types are TN (cheaper, worse viewing angles), IPS (very balanced in color and angles) and OLED (pure blacks, brutal contrast and very vivid colors). IPS is the most versatile option; OLED is spectacular for film and creation.although it usually makes the equipment quite expensive.

The finish also matters: Matte screens are generally less tiring on the eyes and produce fewer reflections.Glossy screens offer a more vibrant color experience but suffer in direct sunlight. Touchscreens are almost always glossy and increase the price, but they can be very useful on 2-in-1 convertibles.

Aspect ratio and refresh rate

It's not all about size and resolution; screen aspect ratio also matters. The 16:9, 16:10, and 3:2 aspect ratios indicate how much vertical height you have. with respect to width.

16:9 is the classic standard for film and TV: Perfect for watching videos, a bit less ideal for working with long documents.The 16:10 aspect ratio adds a little height and feels more comfortable for productivity and multitasking. The 3:2 aspect ratio is even more square, highly valued in photography and tasks where vertical space is crucial.

The refresh rate, measured in hertz (Hz), indicates how many times the image is updated per second. The standard 60 Hz is suitable for office applications and general use.But for gaming, 120, 144 or even 240 Hz are appreciated, providing noticeable fluidity in movement.

Battery and real autonomy

Battery life is critical if you work away from home or move around a lot. Official data from manufacturers is usually very optimistic.These figures are calculated under light usage conditions. In normal, the actual figure will be considerably lower in everyday use.

As a general rule, if you're going to be working or studying away from home often, look for laptops that promise at least 8 hours of battery life with light office useThere are ranges, such as some LG gram or MacBook models, that easily exceed 15-20 hours in certain scenarios, while many gaming models are limited to 2-4 hours if you play games or push the GPU to its limits.

If battery life is your priority, look for efficient processors (U series or equivalent, ARM chips like Snapdragon or Apple M) and low-power memory. It also helps that the device can be charged via USB-Calthough don't expect the fast charging speeds of some mobile phones.

And no, it's perfectly fine to use your laptop plugged in all the time: Modern batteries no longer charge to 100% and the device is powered by the chargerIf you want to take even better care of the battery, many manufacturers offer software to limit the maximum charge to 80%.

Ports, connections and webcam

Laptops are increasingly coming with fewer physical ports, so it's a good idea to check this aspect carefully before buying. The minimum reasonable requirement today is to have several USB-C ports, some "traditional" USB-A ports, and a video output (HDMI or USB-C with DisplayPort mode)..

Thunderbolt is a high-speed standard that uses the USB-C connector but offers much more versatility: It allows you to connect monitors, very fast storage, and even external GPUs. via a single cable. Not all USB-C ports are Thunderbolt, so check the specifications.

In terms of wireless connectivity, almost all new models now feature at least Wi-Fi 6, which is sufficient for most users. Wi-Fi 6E adds less congested bands and a bit more headroomwhile Wi-Fi 7 looks more to the future and to scenarios of low latency and high bandwidth (VR, 8K streaming, etc.).

An Ethernet port is still highly recommended if you're going to play online or need the most stable connection possible. It's also useful to have an SD or microSD card reader. If you work with cameras, you can always use adapters if your laptop doesn't include them.

Finally, don't underestimate the webcam: For professional video calls, it's best to look for models with a Full HD (1080p) camera and at least 30 fps.Many built-in webcams are still very basic, so check this point if you spend your day on Zoom, Teams or similar.

Recommended settings according to user type

With all the concepts on the table, let's specify a little more what type of configuration makes the most sense for each typical profile. It's not about specific brands, but about combinations of processor, RAM, graphics card, screen, and battery that fit better depending on the use.

Laptop for studying, office work and home use

If the laptop is going to be used for studying, browsing, doing work, occasional video calls and watching series, you can adjust the budget quite a bit. A recent-generation Intel Core i3 or i5 processor or a Ryzen 3/5 It will give you plenty of leeway.

For RAM, ideally you should go for at least 8 GB, or better yet 16 GB if your budget allows. A 512GB SSD is a very balanced figure so you don't run out of space.especially if you're saving notes, PDFs, photos, and some multimedia content.

The graphics card can be integrated without any problem. The screen is a 14″ or 15,6″ Full HD display with an IPS panel and good brightness. It will give you a comfortable experience both at home and in class. Battery life is key here: look for something that can withstand a full day of studying without any problems.

Lightweight laptop for serious work and creation

If you work with advanced productivity tools, do some photo/video editing, code, or project management, and highly value mobility, Mid-to-high-end ultrabooks and MacBook Air/Pro are the top contenders.

The sensible thing to do is look at modern Intel Core i5/i7 or Ryzen 5/7 processors, or Apple's M chips (M2, M3, M4 depending on budget). In these profiles, 16 GB of RAM has practically become the standard. to have plenty for years.

For storage, 512 GB or 1 TB is better if you handle a lot of large files. Integrated graphics can be used if your work doesn't depend on 3D or demanding gaming.since the current integrated graphics offer a good boost for moderate editing and light AI tasks.

Look for 14-16″ screens with good resolution (at least Full HD, ideally 2K or similar) and an IPS or OLED panel. A battery that lasts around or above 10-12 hours of mixed use It makes a big difference in this segment.

Gaming laptop and for demanding professional use

For serious gaming, working with 3D, CAD/BIM, rendering or advanced video editing, the ideal profile is very close to a gaming laptop or a mobile workstation. These systems sacrifice some lightness in exchange for sustained power and more robust cooling systems..

For CPUs, it's common to look for H or HX series from Intel and AMD, or high-performance equivalents. 16 GB of RAM is the minimum for this profile, and 32 GB becomes highly recommended. if you are going to open large projects or use virtual machines.

In this case, installing a powerful dedicated graphics card is almost mandatory: GeForce RTX-type ranges in their Laptop or Radeon RX versions with at least 6-8 GB of VRAM to play at 1080p with good quality, going up to 12-16 GB of VRAM if you're aiming for 1440p, 4K or professional AI and intensive rendering loads.

15,6″ or 16″ screens are usually the norm, with 1080p or 1440p resolutions and high refresh rates (144 Hz, 165 Hz or more) that enhance the gaming experience. Battery life is not usually the strong point of these laptops.So it's best to assume that they perform best when plugged in.

Other factors that influence the experience: keyboard, design, and cooling

Beyond the pure specifications, there are details that many technical data sheets overlook and that, in everyday life, matter (a lot). The keyboard, the trackpad, the cooling system, and the build quality They can make the difference between a nice laptop and one that drives you crazy.

The keyboard is your main tool. It's worth checking that it has a Spanish layout (with ñ), comfortable key travel, and, if possible, backlighting. to write in low light; for example, you can consult an analysis of Logitech Keys To Go portable keyboardOn large laptops, a dedicated numeric keypad can be useful.

Cooling is key, especially in powerful equipment: Poor design means more heat, more noise, and performance losses due to thermal throttling. (The CPU/GPU slows down when it gets too hot.) Using a cooling pad with fans helps a lot here, especially with gaming or high-performance laptops.

It's also worth looking at the quality of the chassis: Materials like aluminum tend to offer more rigidity and a feeling of solidity.Although some plastics are of good quality, a well-designed body and hinges can extend the device's lifespan and improve the user experience.

Where to buy and which brands to trust

Once you've decided on the type of laptop and configuration, it's time to choose where to buy it. Trust in the store is almost as important as the model itself.especially regarding returns, warranties, and potential future problems.

Online stores have evolved tremendously: nowadays it's common to find Prices between 10% and 50% lower than in many physical storeswith fast shipping and good customer service. Many large chains even offer in-store pickup and returns for online purchases.

When choosing a store, pay attention to the return policies, customer reviews, and after-sales service. A store that makes things easy when something goes wrong is worth more than saving a few euros. in the initial purchase.

Regarding brands, almost all major manufacturers (HP, Lenovo, Dell, ASUS, Acer, Apple, LG, etc.) have good, medium, and poor ranges. Each brand usually has a "strong point": robustness, lightness, autonomy, design, value for money…that's why it's advisable to compare specific models and not just focus on the logo.

Frequently asked questions and common doubts

Finally, it is worth addressing some of the most common questions that arise when someone considers buying a new laptop. These are recurring questions about upgrades, batteries, soldered RAM, Wi-Fi, and operating systems. which should be clear.

Can a laptop be upgraded (RAM and SSD)?

It depends on the model. It's still possible on many devices. replace the SSD and upgrade the RAM if there are free slots.But in others (especially ultralights and some MacBooks) the memory is soldered to the motherboard and cannot be modified afterwards.

Before buying, carefully review the specifications or technical manuals: If the laptop doesn't allow RAM upgrades and you know you might need more in the future, it's best to buy it with enough room to spare.The SSD is usually easier to replace, even in slim models, but this is not a universal rule.

Intel or AMD? And what about ARM?

Today, both Intel and AMD offer very competitive product lines. Intel typically excels in per-core performance and ecosystem.While AMD has gained a lot of fame for its good results in gaming, multi-core and efficiency in some Ryzen series.

In practice, the choice between one or the other usually depends more on the specific model, the offer, and the design of the laptop than on the brand. For the average user, with equivalent processors of the same generation, the real difference is usually not dramatic..

Meanwhile, Windows on ARM with chips like the Snapdragon X has improved considerably. It offers very good battery life and good performance in light and moderate use.However, you still need to carefully check the compatibility of specific programs and drivers if you depend on professional software or specific games.

Is it bad to use a laptop that's always plugged in?

No, with current batteries there's no problem using it plugged in almost all the time. When the battery reaches 100%, the system stops charging and starts drawing power directly from the charger.It is not being constantly "overloaded".

If you're obsessed with maximizing battery life, some manufacturers include options for limit the maximum load to 80% or 90%which can help extend its lifespan a little, especially if the laptop spends almost all day plugged into the desk.

What screen size is best for working, studying, and traveling?

For moving around a lot with your laptop (travel, daily commutes), the most comfortable options are usually 13-14 inch devices that fit in almost any backpack and weigh very littleIf you're going to study at home and will hardly be carrying it around, a 15,6″ screen might be perfect.

For professional use (office or studio) and tasks such as editing, design, or gaming, The 16-17 inch screens offer an experience closer to a desktop computer.However, it's worth acknowledging that they aren't the most comfortable to travel with every day.

Is a Chromebook worth it or is Windows/Linux better?

Chromebooks make sense if your usage is almost entirely online: browsing, cloud-based office applications, video, networking, and little elsewith the advantage of a very simple, fast and economical system.

If you know you'll need specific desktop programs, professional tools, or want room for games and native applications, A low/mid-range Windows or Linux laptop is usually a more versatile option. in the medium and long term.

Ultimately, buying a decent laptop is about making sense of all the information: being very clear about its main use, understanding the difference between processor ranges, how much RAM you'll really need, what type of graphics card suits you best, and what screen and battery fit your daily needs; if you add to that some care when choosing a store and brand, and pay attention to practical details like the keyboard, cooling, or available ports, It's much easier to end up with a laptop that will last you for several years without giving you any trouble and that adapts to your actual way of working, studying, playing and enjoying time in front of the screen.
