Refresh rate

The frame rate supported by the laptop screen. In fact, in this case we are talking about the maximum frequency; the actual frame rate may be lower than this value, depending on the content being displayed — but not higher.

Theoretically, the higher the frame rate, the smoother the movement on the screen will look, the less moving objects will be blurred. In fact, the situation is such that even in relatively modest modern laptops, 60 Hz matrices are installed — in general, this is quite enough for the human eye, since a further increase in speed ( 90 Hz and higher) does not significantly improve the visible “picture”. However, in high-end gaming and multimedia models designed for demanding users, higher values — 120 Hz, 144 Hz, 165 Hz and even higher, namely 240 Hz and 300 Hz.

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.

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 (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.

HDR

HDR technology format supported by the laptop.

This technology is designed to expand the range of brightness reproduced by the laptop screen; Simply put, an HDR screen will display brighter whites and darker blacks than a regular matrix. In fact, this can significantly improve image quality. First, the expansion of the dynamic range contributes to the brightness and fidelity of colours on the screen; secondly, the visibility of individual details in very bright or very dark areas of the frame is preserved (whereas on a normal screen such details often “sink” in solid white or black).

Note that in order to fully use this function, you need not only a laptop with HDR, but also the corresponding content (video files recorded in HDR, games where this technology is implemented, etc.). In addition, the laptop must support the HDR format used by the content being played. Nowadays, you can find such options:

— HDR10. Historically the first of the consumer HDR formats, less advanced than those described below, but extremely widespread. In particular, HDR10 is supported by almost all streaming services that provide HDR content at all, and it is also common for Blu-ray discs. Allows you to work with a colour depth of 10 bits (hence the name). At the same time, devices of this format are also compatible with content in HDR10 +, although its quality will be limited by the capabilities of the original HDR10.

...— HDR10+. An improved version of HDR10. With the same colour depth (10 bits), it uses the so-called dynamic metadata, which allows transmitting information about the colour depth not only for groups of several frames, but also for individual frames. This results in an additional improvement in colour reproduction.

Dolby Vision. An advanced standard used particularly in professional cinematography. Allows you to achieve a colour depth of 12 bits, uses the dynamic metadata described above, and also makes it possible to transmit two image options at once in one video stream — HDR and normal (SDR). At the same time, Dolby Vision is based on the same technology as HDR10, so in laptops it is almost guaranteed to be combined with at least HDR10, and even with HDR10 +.

AMD compatibility

The laptop supports AMD FreeSync technology and its more advanced varieties (FreeSync Premium, FreeSync Premium Pro). Here are more details about them:

– AMD FreeSync. This function is found only in models equipped with discrete AMD graphics cards. It serves to match the frame rate of the screen and the frame rate of the incoming signal so that the frequencies match. This allows you to avoid flickering, jerking and other image defects that occur due to signal desynchronization. This function 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 FreeSync are specifically gaming laptops.

– AMD FreeSync Premium. An intermediate option between the core AMD FreeSync technology and the advanced FreeSync Premium Pro implementation. The Premium version does not have HDR support (unlike Pro), but it works at the same frame rate (at least 120 fps at a resolution of 1920x1080) and uses LFC low frame rate compensation technology.

– FreeSync Premium Pro. The most advanced version of FreeSync technology, formerly known as AMD FreeSync 2 HDR. As the original name suggests, one of the highlights of this edition is HDR support. FreeSync Premium Pro claims a frame rate of at least 120 fps at Full HD resolution, as well as a low frame rate compensation (LFC) function. According to the creators, FreeSync Premium Pro works espec...ially well in games; and many modern games are initially created to work with this technology.

NVIDIA video cards use a similar technology called G-Sync.

Series

Each series combines chips that are similar in general level, purpose, and often also in individual specific features. At the same time, most series include processors of several generations at once, which can differ significantly in actual characteristics. It is worth noting that until recently, laptops were almost exclusively equipped with processors from AMD or Intel - until in 2020, Apple introduced its own chip Apple M1(with updated versions of Apple M1 Pro and Apple M1 Max), Apple M2(2022) with productive chips M2 Pro, M2 Max and Apple M3, M3 Pro, M3 Max(2023). Then Qualcomm entered the arena with its Snapdragon processors.

At the moment, the following series are mainly relevant in laptops:

AMD Ryzen 3. The cheapest series of AMD chips in the Ryzen family (Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9 and Ryzen AI), using the Zen microarchitecture. In ter...ms of general design, Ryzen 3 is similar to its older brothers, but half of the computing cores are deactivated. Nevertheless, it is quite advanced and is even found in ultrabooks.

— Ryzen 5. The second series on the Zen architecture is a more affordable alternative to the Ryzen 7 chips. Ryzen 5 chips have slightly more limited performance characteristics (in particular, a lower clock frequency and, in some models, L3 cache volume). Otherwise, they are completely similar to the "sevens" and are also positioned as high-performance chips for gaming and workstations. For more details, see "Ryzen 7" below.

— Ryzen 7. The first series of processors from AMD, built on the Zen microarchitecture. It was introduced in March 2017. In general, Ryzen chips (of all series) are promoted as high-end solutions for gamers, developers, graphic designers and video editors. One of the main differences between Zen and previous microarchitectures was the use of simultaneous multithreading, due to which the number of operations per clock was significantly increased at the same clock frequency. In addition, each core received its own floating-point calculation unit, the speed of the first-level cache memory increased, and the L3 cache volume in Ryzen 7 chips is 16 MB by default.

— Ryzen 9. AMD Ryzen 9 processors on the Zen microarchitecture debuted in 2019. The series became the top among all Ryzens, displacing Ryzen 7 from this position. First of all, the CPU line is usually used for professional tasks (design, video editing, 3D rendering), games, streaming and other high-load applications. The first Ryzen 9 models had 12 cores and 24 threads, in later ones this number was increased to 16 and 32, respectively.

— Ryzen AI. The Ryzen series of processors with artificial intelligence was launched in 2024. The first in the lineup was the AMD Ryzen AI 300 subfamily. It introduces the new Zen 5 computing core architecture, has integrated RDNA 3.5 graphics, and a powerful XDNA 2 neural processor with a performance of up to 50 TOPS (trillion operations per second). The Ryzen AI chips are perfect for a wide range of tasks — from everyday work to complex calculations using AI algorithms.

— Atom. Processors specially developed by Intel for mobile devices (including smartphones). Used mainly in ultra-compact laptops.

— Core M. Processors designed for portable devices (in particular, ultra-compact laptops) and featuring extremely low heat generation, allowing the use of passive cooling systems. They were introduced in 2014 as the first serial chips using the 14 nm process technology.

Celeron. The most budget series in the modern line of desktop processors from Intel. However, the latest generations are equipped with integrated graphics.

Pentium. Budget desktop processors from Intel, slightly superior in characteristics to Celeron, but not up to the Core i3. Also have integrated graphics.

Processor. A line of entry-level processors that precedes the Core i3 family in Intel's modern hierarchy. These chipsets are found in entry-level laptops designed for everyday home or office use, as well as undemanding games.

Intel Core i3 / Core 3. A series of entry-level and mid-range processors, the most budget-friendly in the Core family. However, in terms of characteristics and computing power, the processors of this line are superior to the Pentium and Celeron series (see above).

Intel Core i5 / Core 5. A line of mid-range processors — both in general and by the standards of the Core family in particular. Most often, the processors of the series contain from 4 to 10 cores, and in terms of performance, they are between the relatively inexpensive i3 (Core 3) and the powerful i7 (Core 7).

Intel Core i7 / Core 7. A series of high-performance processors from Intel. Before the i9, it was the most advanced in the Core family, but then it gave way to the "nine". Core 7 chips have at least 4 cores and integrated graphics.

Core i9. Top-end processors released in 2017; the most powerful line of consumer-grade notebook processors at the time of their release, displacing Core i7 chips from this position. They have 6 cores and a large L3 cache.

Core Ultra 5. A transformation of the popular series of mobile processors of the strong mid-range Intel Core i5, which received the Ultra prefix since the end of 2023 — when the Meteor Lake generation of chipsets debuted. The main feature of the Core Ultra 5 processors is a separate NPU, which gives advantages when working with AI models.

Core Ultra 7. A pre-top series of high-performance mobile processors from Intel, which replaced the Core i7 family at the end of 2023 (with the advent of the new generation of Meteor Lake chipsets). A mandatory attribute of the Ultra models has become a neural coprocessor, responsible for accelerating the operation of artificial intelligence algorithms.

Core Ultra 9. The most powerful line of laptop processors from Intel, released to replace the Core i9 family at the end of 2023. The premiere of models with the Ultra addition took place in the Meteor Lake chipset generation. A distinctive feature of Intel Core Ultra 9 is the presence of a separate NPU to improve the efficiency of using artificial intelligence models.

— Apple. A series of processors from Apple, which debuted in November 2020 with the release of the next generations of MacBook, MacBook Air and MacBook Pro. In the initial configurations, they are equipped with 8 cores - 4 productive and 4 economical; the latter, according to the creators, consume 10 times less energy than the former. This, combined with the 5 nm process technology, made it possible to achieve very high energy efficiency and, at the same time, performance. It is also worth noting that the processors of this series are made according to the system-on-chip scheme: a single module combines a CPU, a graphics adapter, RAM (in the first models - 8 or 16 GB), a solid-state NVMe drive and some other components (in particular, Thunderbolt 4 controllers).

— Snapdragon. Snapdragon processors are essentially mobile solutions — they are traditionally installed in smartphones and tablets. Separate lines of Snapdragon chips have been released specifically for laptops (for example, X Elite on ARM architecture). Many laptops based on such processors are equipped with built-in LTE or even 5G modules. Their advantage is also high energy efficiency.

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.
