These budget systems typically won't include a lot of gamer bling like customizable RGBs and multi-zone keyboard lighting. Many will cut necessary cost corners by using a plastic chassis instead of aluminum, and you won't see sexy thin bezels like those on the MateBook Pro or Dell XPS 13. You'll also get, at minimum, 3 USB ports, an HDMI output and standard headphone jacks.
Gaming laptops need to have the necessary processing power to run high-end games. Laptops with good processing speed help run your games seamlessly without any lag. When it comes to a CPU, the important elements to be considered are the number of cores it contains and its processing speed. A laptop with a powerful CPU ensures a lag-free gaming experience.
Processors are the next biggest difference. You'll likely get a capable Core i5 instead of a faster Core i7. Still, some of the benefits of an i7 machine aren't a major factor for gaming, but instead benefit video editing and other creative uses, so an i5 will do the job. The newest generation of these chips are fast and efficient at a base level, and won't be too much of a bottleneck for gaming. On the AMD side of the fence, in the rare gaming laptops you'll find based wholly on AMD core technology, gamers will see mostly graphics solutions based on the now-aging Radeon RX 560, RX 570, and RX 580 paired with one of several AMD FX or Ryzen CPUs. Outside of the graphics card and processor, the other components should actually be closer to more expensive machines than you'd expect.
That said, a maxed-out Core i7 CPU is less crucial for gaming than it is for processor-intensive tasks such as video editing and media-file production work. With current-generation Intel CPUs, you'll get plenty of pep even from a four-core "Coffee Lake"/8th Generation Core i5. A Core i7 of the same generation is actually a hefty six-core/12-thread processor that, we'd argue, is overkill for casual gamers who need to mind what they spend. So, our bottom line: Opt for a Core i5 or i7 chip with four true cores if you can; a six-core chip is gravy.
One of the typical features that sets apart a gaming laptop is a colorful, backlit keyboard. These vary quite a bit from model to model, with more elaborate backlighting going hand-in-hand with higher prices and a higher general level of other components. Almost all budget gaming laptops will employ single-color backlighting (most often, red or white) to keep costs down. The next step up is lighting programmable by zone, with three or four blocks of the keyboard independently customizable in different colors, but this is not common in budget machines. Keyboards with per-key, individually programmable lighting are the province of high-end machines only.
