Brightness

The maximum brightness that a laptop screen can provide.

The brighter the ambient light, the brighter the laptop screen should be, otherwise the image on it may be difficult to read. And vice versa: in dim ambient light, high brightness is unnecessary — it greatly burdens the eyes (however, in this case, modern laptops provide brightness control). Thus, the higher this indicator, the more versatile the screen is, the wider the range of conditions in which it can be effectively used. The downside of these benefits is an increase in price and energy consumption.

As for specific values, many modern laptops have a brightness of 250 – 300 nt and even lower. This is quite enough for working under artificial lighting of medium intensity, but in bright natural light, visibility may already be a problem. For use in sunny weather (especially outdoors), it is desirable to have a brightness margin of at least 300 – 350 nt. And in the most advanced models, this parameter can be 350 – 400 nt and even more.

Contrast

The contrast of the screen installed in the laptop.

Contrast is the largest difference in brightness between the lightest white and darkest black that can be achieved on a single screen. It is written as a fraction, for example, 560:1; while the larger the first number, the higher the contrast, the more advanced the screen is and the better the image quality can be achieved on it. This is especially noticeable with large differences in brightness within a single frame: with low contrast, individual details located in the darkest or brightest parts of the picture may be lost, increasing the contrast allows you to eliminate this phenomenon to a certain extent. The flip side of these benefits is an increase in cost.

Separately, we emphasize that in this case only static contrast is indicated — the difference provided within one frame in normal operation, at constant brightness and without the use of special technologies. For advertising purposes, some manufacturers may also provide data on the so-called dynamic contrast — it can be measured in very impressive numbers (seven-digit or more). However, you should focus primarily on static contrast — this is the basic characteristic of any display.

As for specific values, even in the most advanced screens, this indicator does not exceed 2000: 1. But in general, modern laptops have a rather low contrast ratio — it is assumed that for tasks that require more advanced image characteristics, it is more...reasonable to use an external screen (monitor or TV).

Colour gamut (sRGB)

The colour gamut of the laptop matrix according to the Rec.709 colour model or according to sRGB.

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, sRGB and Rec.709 are the most popular of today's colour models; they have the same range and differ only in the scope (sRGB is used in computers, Rec. 709 is used in HDTV). Therefore, the closer the colour gamut is to 100%, the more accurately the colours on the screen will match the colours that were originally intended by the creator of the film, game, etc. At the same time, note that such accuracy is not particularly needed in everyday use — it critical only for professional work with colour; and even in such cases, it is more convenient to buy a separate monitor with a wide colour gamut for a laptop, rather than looking for a laptop with a high-quality (and, accordingly, expensive) matrix.

Colour gamut (Adobe RGB)

The colour gamut of the laptop matrix according to the Adobe RGB 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.

The Adobe RGB colour model was originally developed for print applications; the range of colours covered by it corresponds to the capabilities of professional printing equipment. Therefore, theoretically, the extensive coverage of this model will be useful to those involved in the design and layout of high-end printed products. However most laptop screens have very limited Adobe RGB values, rarely exceeding 74%; however, you can also find high-end models where this figure approaches 100%. Of course, the cost of such laptops will also be appropriate; therefore, it makes sense to pay attention to them, first of all, when the ability to work with colour “on the go” is of key importance. If this is to be done in one place, it may be more justified to buy a separate monitor with a wide colour gamut (especially since a monitor with such characteristics is easier to find than a laptop).

NVIDIA G-Sync

Laptop support for NVIDIA G-Sync technology.

This feature is only found on models equipped with discrete NVIDIA graphics cards. It is used to match the frame rate of the screen and the frame rate of the signal arriving at it — so that these frequencies match. This avoids flickering, twitching, and other image artifacts that can occur due to out-of-sync. This feature is especially useful for games where the frame rate of the video signal can "float" depending on the load on the graphics core; in fact, most laptops with G-Sync are specifically for gaming.

A similar solution for AMD video cards is called FreeSync.

Model

The specific model of the processor installed in the laptop, or rather, the processor index within its series (see above). Knowing the full name of the processor (series and model), you can find detailed information on it (up to practical reviews) and clarify its capabilities.

Code name

The code name for CPU installed in the laptop.

This parameter characterizes, first of all, the generation to which the processor belongs, and the microarchitecture used in it. At the same time, chips with different code names can belong to the same microarchitecture/generation; in such cases, they differ in other parameters - general positioning, belonging to certain series (see above), the presence / absence of certain specific functions, etc.

Nowadays, the following code names are relevant in Intel processors: Coffee Lake, Comet Lake, Ice Lake, Tiger Lake, Jasper Lake, Alder Lake, Raptor Lake (13th Gen), Alder Lake-N, Raptor Lake (14th Gen), Meteor Lake (Series 1), Raptor Lake (Series 1), Lunar Lake (Series 2). For AMD, the list looks like this: Zen 2 Renoir, Zen 2 Lucienne, Zen 3 Cezanne, Zen 3 Barcelo, Zen 3+ Rembrandt, Zen 3+ Rembrandt R, Zen 2 Mendocino, Zen 3 Barcelo R, Zen 4 Dragon Range, Zen 4 Phoenix Zen 4 Hawk Point, Zen 5 Strix Point. Detailed data on different code names can be found in special sources.

CPU speed

The clock speed of the processor installed in the laptop (for multi-core processors, the frequency of each individual core).

Theoretically, a higher clock speed has a positive effect on performance, as it allows the processor to perform more operations per unit of time. However, in fact, the capabilities of the CPU depend on a number of other characteristics — primarily on the series to which it belongs (see above). It even happens that of the two chips, the more performant in the overall result is the slower one. With this in mind, it makes sense to compare by clock frequency only processors of the same series, and ideally, also of the same generation; and the laptop as a whole should be judged by the complex characteristics of the system, as well as by the results of tests (see below).

TurboBoost / TurboCore frequency

Processor clock speed achieved in TurboBoost or TurboCore "overclocking" mode.

Turbo Boost and Turbo Core technologies are used by different manufacturers (Intel and AMD, respectively), but they have the same principle of operation: load distribution from more loaded processor cores to less loaded ones to improve performance. The "overclocking" mode is characterized by an increased clock frequency, and it is indicated in this case.

For more information about clock speed in general, see the relevant paragraph above.
