Surface treatment
—
Glossy. A glossy surface improves the overall picture quality: other things being equal, the picture on such a screen looks brighter and more colorful than on a matte one. On the other hand, pollution is very noticeable on such a surface, and in bright external lighting, a lot of glare appears on it, which can greatly interfere with viewing. Therefore, instead of the classic gloss, laptops are increasingly using an anti-reflective version of such a coating (see below). Nevertheless, this option still does not lose popularity: it is somewhat cheaper than the “anti-glare”, and in soft, relatively dim lighting, it can even provide a more pleasing image to the eye.
—
Matte. Matte finish is inexpensive and does not form glare even from fairly bright lighting. On the other hand, the picture on such a screen is noticeably dimmer than on a similar glossy display. However, this moment can be compensated by various design solutions (primarily a good margin of brightness); so this option can be found in all categories of modern laptops — from low-cost models for working with documents to top gaming configurations.

Glossy (anti-glare). A variation on the glossy finish described above, designed to reduce glare from external light sources. Such screens really glare noticeably less than traditional glossy ones (or even do not give glare at all); at the same time, in
...terms of image quality, they are at least superior to matte ones. So it is this type of coating that is most popular nowadays.Colour gamut (NTSC)
The colour gamut of the laptop matrix according to the NTSC colour model.
Colour gamut describes the range of colours that can be displayed on the screen. It is indicated as a percentage, but not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the screen's capabilities, the better its colour reproduction.
Specifically, NTSC is one of the first colour models created back in 1953 for colour television. It is not used in the production of modern LCD matrices, but is used to describe and compare them. NTSC covers a wider range of colours than sRGB, which is standard in computer technology; therefore, even a small number of percentages in this case corresponds to a fairly wide coverage. For example, a value of
72% or more in NTSC is already considered a good value for use in design and graphics. At the same time, the same NTSC figures on different screens may correspond to different sRGB figures; so if accurate colour reproduction is decisive for you, these details should be clarified before buying.
Also note that among individual monitors, it is easier to find a screen with a wide colour gamut; while it will also cost less than a laptop with similar display characteristics. So choosing a laptop with a h
...igh-end screen makes sense mainly when portability is as important to you as high-quality colour reproduction.Passmark CPU Mark
The result shown by the laptop processor in the Passmark CPU Mark test.
Passmark CPU Mark is a comprehensive test that is more detailed and reliable than the popular 3DMark06 (see above). It checks not only the gaming capabilities of the CPU, but also its performance in other modes, based on which it displays the overall score; this score can be used to fairly reliably evaluate the processor as a whole (the more points, the higher the performance).
RAM
The amount of random access memory (RAM or RAM) actually installed in the laptop.
The amount of RAM is one of the most important indicators characterizing the overall flow Rate of the system. The more RAM installed in a laptop, the better it will cope with “heavy” resource-intensive programs, and the more tasks can be performed on it simultaneously without “brakes” and failures.
Today
, 4 GB of RAM is considered the minimum required. A capacity of
8 GB is usually enough for comfortable household use and simple games,
16 GB and
32 GB are enough for running resource-intensive applications and confidently launching modern games. And in advanced gaming and professional laptops there are also larger amounts of RAM -
64 GB or even more.
Note that many laptop models allow you to increase the available amount of RAM; For more details, see “Maximum installed volume”.
GPU TDP
The amount of heat generated by the graphics processing unit (GPU) during normal operation. TDP is expressed in watts. It allows you to evaluate the thermal characteristics of a laptop and determine its potential for working with high graphics loads. The higher the GPU TDP value, the more power the GPU consumes, which may require a more efficient cooling system to avoid overheating and ensure stable operation of the device. Laptops with higher GPU heat dissipation are better suited for gamers or graphics and video production professionals.
Additional M.2 connector
The number of
additional M.2 connectors on the laptop motherboard.
In this case, any free M.2 connector is called additional (if there is an installed drive, the connector is considered the main one and its characteristics are given above — see "M.2 connector interface" and so on). There may be
several such free slots — therefore, our catalog specifies the number of additional M.2 connectors, and not just their presence.
Anyway, this parameter will be useful primarily if the laptop is bought for an upgrade. It allows you to estimate how many M.2 SSDs (or other peripherals with such a connection) can be additionally installed in the device. At the same time, when choosing specific components, you should also take into account the interface and the size of free M.2 slots (see below for more details).
Addittional M.2 connectors interface
A connection interface supported by the laptops optional M.2 connector (see above). Recall that this connector is initially free; so this information allows you to evaluate the compatibility with additional components and, accordingly, the possibility of upgrading.
Two main types of interfaces can be implemented through the M.2 connector: SATA and PCI-E. SATA was originally created for hard drives, its support is inexpensive, but the speed of such a connection does not exceed 600 MB / s — this is very low by the standards of SSDs and other modern peripherals. Therefore, in the additional connector (s) M.2, one or another type of PCI-E is most often implemented. This interface has several variations that differ in version, number of lines and, as a result, speed; Here are the options most relevant for modern laptops:
— PCI-E 3.0 2x. Connecting using 2 lanes of PCI-E version 3.0 gives a maximum speed of just under 2 GB / s.
— PCI-E 3.0 4x. Connection using 4 lanes PCI-E version 3.0. Provides a maximum speed of about 4 GB / s.
— PCI-E 4.0 4x. Connected using 4 lanes PCI-E version 4.0, throughput is about 8 Mbps.
— PCI-E. Connection via PCI-E, for which the manufacturer did not specify the details (version and number of lines).
It is worth noting here that in the case of M.2, different versions of PCI-E are quite compatible with each other (except that the speed of work will be limited by the capabilities of the slower side —...the drive or connector). Therefore, even if the specific capabilities of such a connector are not specified, this is generally not critical (these capabilities will not hurt to clarify unless if high performance is fundamentally important to you).
Additional M.2 drive size
The size of an additional slot for a drive (or other peripherals) with an M.2 interface provided in a laptop.
We emphasize that in this case we are not talking about the actually installed drive, but about the size of the bay (recall, there is no drive in it initially — for more details, see "Additional M.2 connector"). Knowing this size, you can estimate the maximum dimensions of the SSD module (or other component) that can fit in this bay. It is worth noting here that the most widespread nowadays are M.2 boards with a width of 22 mm, slots in laptops are usually made for this standard width. Therefore, the main indicator that determines size compatibility is length.
For bays on laptop motherboards, the length is most often 80 mm (marking 22x80 mm). This allows you to install 22 mm M.2 boards with a length of 80 mm, 60 mm, 42 mm and 30 mm — that is, all types of such boards, except for the largest, at 110 mm. The latter, however, is not a disadvantage, since 110-mm components are rarely used in laptops. If there are several additional (free) M.2 slots and they differ in size, these data are also specified in this paragraph, for example, “22x80 / 22x42 mm”.
Lighthing sync
Backlight sync technology supported by the laptop.
For lighting in general, see above; here we recall that we are talking about a laptop keyboard. And synchronization allows you to "coordinate" the operation of this system with the illumination of other components connected to the laptop — a mouse, keyboard, speakers, etc. Thanks to this, you can simultaneously turn on and off the backlight, change the brightness, create various effects, etc. Separately, it is It should be noted that synchronization is used mainly in RGB systems, which can also change the hue of the glow — this provides even more extensive possibilities. However, proper backlight matching requires all components to support the same timing technology; This item just allows you to evaluate such compatibility. At the same time, each manufacturer, usually, creates its own technology — for example, Asus has Aura Sync, MSI has Mystic Light Sync, etc. So the easiest way to achieve compatibility is to buy components of the same brand for a laptop.
