When you’re choosing a new laptop or desktop computer, it’s important to understand the specs and features you’ll see listed by each model. That way, you can be sure to choose the right laptop for your own particular needs.

Knowing what processor to go for, how much Ram you’ll need and whether or not you require a graphics card are all questions will have a bearing on your setup, and your budget.

We explain some of the key components to look for when picking up your new laptop.

What are Good Laptop Specs?

  • Processor – The brains of the laptop, the better the processor, the faster your computer will run. For a dependable laptop, an Intel i3 is fine, but an i5 will guarantee good speeds. Laptops with i7 chips cost a lot more, and are more suited to those running design software or games.
  • Screen – Size and resolution of screen will have a big impact on your experience. It’s best not to go smaller than a 13-inch screen, though you can live without 4K displays unless you’re a professional designer or photo-editor. Full HD resolution is fine.
  • Storage Space – The amount of space you can use to store your files. It’s best not to accept less than 256GB for a solid state drive (SSD, which helps laptops run faster), or less than 1TB for a traditional hard drive (not as fast, but more generous with the storage).
  • Ram – Used for juggling multiple applications at once. More Ram can give you a speed boost. These days, 8GB Ram is the minimum to aim for. 16GB or 32GB is only needed for high-end machines.
  • Graphics card – An additional graphics card is used for gaming and image editing. If you only need to browse the web, email and stream video, you can live without an advanced graphics card.


Processor

There are two main players in the laptop space, Intel and AMD, although the vast majority of the models you’ll find on store shelves with feature an Intel chip. These typically come in the flavour of i3, i5 or i7. In the most basic terms, the bigger the number, the better the processor.

An Intel Core i3 processor will be fine for anyone not looking to do much on their laptop outside basic tasks. But, for those needing raw power and a chip that can handle heavy workloads, the i7 is the best choice. It’s also important to check the generation of your Intel processor. Receiving regular upgrades, an i7 processor from 2014 is a totally different beast to one in 2018. Know the latest generation of Intel when shopping around (it’s currently 8th, with 9th on the way), and don’t get duped into picking up something that is already dated.

While AMD may have struggled with its offerings in the past, its latest Ryzen processors can certainly hold their own against Intel, providing a viable alternative at a cheaper price.

The processor, effectively the brains of the laptop, is seen by many as being the most important part of a laptop, and while that’s true to some degree, it’s also important to match it to hardware that will allow it to work to the best of its abilities, such as RAM and a graphics card. Don’t just buy the most powerful processor you can find and expect to be set.

Screen

There are couple of key points to consider when you’re looking at a laptop screen. Firstly, size. How big do you want it to be? A small screen is great for portability, but you might struggle to make out the finer details of a spreadsheet or Netflix blockbuster. Go larger, and you’ll bag a sizeable screen, but it may no longer fit in your bag.

Screen resolution is also something to watch out for. It signifies the number of pixels that are shown onscreen – the bigger the number, the higher the detail. Most laptops will have an HD resolution of 1920 x 1080, which is good enough for daily work and movies, but if you’re looking to do some gaming or carry our some image editing, then you’ll benefit from a higher resolution. The MacBook Pro range for example has its famous Retina screens, which boast a resolution of 2880 x 1800, making for pin sharp images.

You should also consider whether a matt or glossy screen will suit you better. Glossy can look nice, but can be problematic outside when used in bright sun due to screen glare.

Storage – Hard Drive or Solid State Drive?

Storage space on a laptop can be a tricky thing to work out. Do you want all your files accessible locally, or are you happy to make use of the practically infinite space of the cloud?

Do you go for a traditional hard disk (HDD) or a solid state (SSD) one?

It all depends on your needs. If you mainly use your laptop for surfing the web, emailing and writing the odd document, then you won’t need too much space, and chances are it will take you a long time to fill up a fairly typical 500gb hard drive. The rise in digital streaming and loud storage mean that most of us don’t need as much room as we once did.

However, if you’re the sort of person who hoards movies, music and want all your games installed at once, then you’re going to want to go with a pretty large hard drive. The best way to gauge how much space you need is to look at what’s on your current laptop, how much of it you’ll want to transfer over, and then at least double that space.

You’ll have noticed that you get less storage space on an SSD for your buck compared to a HDD. This is because SSDs are faster and can really ramp up the time it takes to load your programs, or even your operating system. The best solution is a SSD/HHD combination, which gives you speed start up times coupled with loads of storage.

RAM

RAM is vitally important in laptops, as it controls the number of functions the machine can do it at once. You might not think it, but your laptop is constantly multi-tasking, juggling your requirements and keeping a several operations running at the same time. With RAM, the more the better, but decking out your laptop with 32GB of RAM can get not only expensive, but also excessive. Get a laptop with not enough RAM though, and it’ll chug its way through every action, and almost weep at being asked to carry out anything vaguely complex.

Most users will find that 8GB of RAM is fairly standard, and will serve them perfectly well for day to day duties. If you think you might need a bit more grunt down the line, look for a laptop which enables you to add your own RAM in the future. This is an easy operation of undoing a few screws and slotting it in – you don’t need to be a tech wizard to speed up your laptop.

Graphics Card

Do you need a graphics card? If you’re an avid gamer or someone who wants to edit a lot of images and video, then the answer is yes. If you’re mainly emailing, surfing and writing the odd office document, then no.

There’s two things to know about graphics cards on laptops. Unlike desktops PCs, they’re practically impossible to retrofit, and they’re expensive. This means that if you want one, not only do you need to buy a laptop top with one installed from the off, you also have to make sure that it’s future proof and will stand you in good stead for a few years. Thanks to the 21st century gold rush for bitcoin, prices for graphics cards, which are a core component for mining, are now inflated.

While this is bad news for gamers and media editors, it’s an important reminder that picking the right laptop with the right graphics card is key, because if it’s struggling a year down the line, you’ll most likely need to replace the whole unit to upgrade.
