Type
General device type.
In addition to traditional laptops, nowadays you can find varieties such as netbooks,
ultrabooks,
2 in 1 tablet laptops and
transformers. Here are their main features:
— A laptop. Laptops of a more or less traditional format that do not belong to any of the specific categories described below. The classic, most popular screen size in these models is
15.6 ".
13.3" and
14" laptops are considered compact,
laptops with a 17.3" screen are large-format, and larger displays are found in advanced gaming models. At the same time, devices from this category are also very diverse in terms of characteristics and capabilities: they range from “typewriters” designed for education and home tasks, to high-end gaming solutions, and workstations and multimedia complexes.
— Ultrabook. High-end laptops that combine compactness, light weight and advanced features. The diagonal in ultrabooks ranges from 11 "to 14", the thickness of the case does not exceed 21 mm, while the internal equipment usually includes powerful processors, a large amount of RAM, fast drives like SSD and other similar solutions. In addition, many devices from this category are made in a characteristic stylish design and are also designed for
...the role of fashion accessories.
— Transformer 360°. Another type of laptop that can turn into a tablet. However, unlike the laptops-tablets described above, in this case, not a removable keyboard is used, but a special swivel connection of the upper and lower blocks. The design of this connection is such that the top of the device can be rotated 360° and placed face up on the keyboard. Thus, the transformer can be converted from a laptop to a tablet without removing the bottom half; this is the fundamental difference between such models and the “2-in-1” described above. This format of work is generally more convenient — no need to look for a place for the removed keyboard, there is no risk of forgetting or losing it; in addition, the mounting design usually allows you to use the device in the format of a “photo frame” — an inclined tablet on a stand without a keyboard. Thus, transformers have become more widespread today than collapsible laptops-tablets. Their disadvantages include the inability to reduce weight by removing the keyboard. The diagonal of such devices can be from 12" to 17".
— 2 in 1 (laptop-tablet). Laptops that can turn into tablets. In such models, the entire “hardware” (or at least its key components) is placed in the upper half, the screen is made touch-sensitive, and the lower half with the keyboard can be completely separated. From traditional tablets, which can also be equipped with keyboards, such devices differ in three main points. The first is more powerful hardware: in particular, most 2-in-1 models carry full-fledged laptop processors (up to and including Core i7), while tablets mainly use CPUs similar to smartphone chips. The second point is a larger screen size, usually 13 – 15". The third caveat is that the keyboard of a laptop-tablet can include not only a set of keys and a spare battery, but also some system components: a discrete graphics card, an additional drive, etc. .
In general, 2-in-1 models are more versatile than traditional laptops; however, nowadays they are much less common than another similar type of laptop — transformers (see below). This is due to the fact that the removable keyboard is not always convenient: when using a device in tablet format, it usually has to be removed; it is not always possible to find a place nearby for the removed keyboard; besides, it can be forgotten or lost through inattention. However, this design also has advantages: for example, if there is enough tablet on the road, there is no need to carry additional cargo in the form of the lower half of the device.Screen size
Diagonal size of laptop display.
The larger the screen, the more convenient the laptop for watching high-definition movies, modern games, working with large-format graphic materials, etc. Large screens are especially important for multimedia and gaming models. On the other hand, the diagonal of the display directly affects the size and cost of the entire device. So if portability is key, it makes sense to pay attention to relatively small solutions; especially since most modern laptops have video outputs like HDMI or DisplayPort and allow connection of large-format external monitors.
In light of all this, the actual maximum for laptops these days is
17"(17.3"); however
larger devices (18") reappeared at the beginning of 2023. The standard option for general purpose laptops is
15"(15.6"), less often
16", a diagonal of
13"(13.3") or
14" is considered small by the standards of such And smaller screens can be found mainly in specific compact varieties of laptops — ultrabooks, 2 in 1, transformers, netbooks; among such devices there are solutions for
12 ",
11" and even
10" or less.
Screen resolution
The resolution of the screen installed in the laptop — that is, the size of the screen in pixels horizontally and vertically.
Higher resolution, on the one hand, gives a sharper, more detailed image; on the other hand, it increases the cost of the laptop. The latter is connected not only with the cost of the displays themselves, but also with the fact that in order to work effectively at high resolutions, you need the appropriate filling (primarily a graphics card). This is especially true in games; so if you are looking for a laptop with a high-resolution screen that can effectively "run" modern games — you should pay attention not only to the characteristics of the display, but also to other data (the type and parameters of the graphics card, test results, the ability to work with certain games — see everything below). On the other hand, if the device is planned to be used for simple tasks such as working with documents, surfing the Internet and watching videos, you can not pay much attention to the “hardware” parameters: anyway, they are selected so that the laptop is guaranteed to be able to cope with such tasks on full resolution of the "native" screen.
As for specific numbers, the resolution options that are relevant today can be divided into 4 groups:
HD (720),
Full HD (1080),
Quad HD and
UltraHD 4K. Here is a mor
...e detailed description of them:
— HD (720). This category includes all displays that have a vertical size of less than 1080 pixels. The most popular HD resolution in modern laptops is 1366x768; in devices larger than 15.6 ", 1600x900 is also often found. Other values quite exotic and are rarely used. In general, screens of this standard are now typical mainly for entry-level laptops.
— Full HD (1080). Initially, the Full HD standard provides a frame size of 1920x1080, and it is this resolution that is most often used in laptop screens from this category. However, in addition to this, other resolution options are also included in this format, where the vertical size is at least 1080 pixels, but does not reach 1440 pixels. Examples include 1920x1200 and 2560x1080. In general, Full HD displays provide a good balance between cost, image quality and laptop hardware requirements. Because of this, nowadays they are extremely widespread; matrices of this standard can be found even in low-cost devices, although they are mainly used in more advanced technology.
— Quad HD. A transitional option between the popular Full HD 1080 (see above) and the high-end and expensive UltraHD 4K. The vertical size of such screens starts from 1440 pixels and can reach 2000 pixels. Note that QuadHD resolutions are especially popular in Apple laptops; most often, such devices have 2560x1600 screens, although there are other options.
— Ultra HD 4K. The most advanced standard used in modern laptops. The vertical size of such screens is at least 2160 dots (up to 2400 in some configurations); the classic resolution of a modern UltraHD matrix is 3840x2160, but there are other values. Anyway, a 4K display allows for high image quality, however, it costs accordingly — including due to the corresponding requirements for a graphics adapter; in addition, to work with high resolutions, it can be more convenient to connect an external monitor to the laptop. Thus, such screens are used relatively rarely, and mainly among premium laptops.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).
Light sensor
A sensor that monitors the intensity of ambient light when working with a laptop. Mainly used for automatic brightness control. So, in a darkened room, the backlight of the screen is dimmed, which reduces eye fatigue and helps save energy; and in bright light, the brightness of the display also increases so that the image remains visible.
Note that, technically, a webcam can be used to estimate ambient light and adjust screen brightness (see below). However, most often this is not a regular way to use it; so the presence of a light sensor is indicated mainly for those devices where a separate specialized sensor is responsible for this function.
Touch
A display with a touch-recognizing sensor, similar to those used in modern tablets.
The touch screen significantly expands the possibilities for managing a laptop: in some situations — for example, when viewing maps — it is most convenient to control the device precisely by touching the display.
Note that by definition, all transformers and 2-in-1 models are equipped with touch screens (see "Type"), but in more traditional laptops this feature is extremely rare — in such devices it is usually more convenient to use a keyboard and mouse.
Gorilla Glass
The presence
of Gorilla Glass in the design of the laptop display; the specific version of such material may also be specified in this paragraph.
The Gorilla Glass brand produces special tempered glass, which, despite its small thickness, has excellent characteristics of strength, transparency and scratch resistance. In general, this coating is more advanced than more traditional materials used in laptops (such as matte or glossy plastic), but it is also more expensive; therefore, it is found mainly in fairly expensive models with high-quality displays, including touch ones.
As for the different versions of this coating, they differ both in protective properties and in a number of other characteristics. Here are the main options relevant today:
- Gorilla Glass v3. The oldest current version was released in 2013. However, even this coating is noticeably superior to traditional glass (not to mention plastic) in terms of transparency and scratch resistance.
- Gorilla Glass NBT. The same age as the v3 version described above, released in 2013. The main feature is that the NBT coating was originally developed specifically for laptops with touch screens (while v3 was created mainly with smartphones in mind). The manufacturer claims, in particular, 8 to 10 times greater scratch resistance than conventional glass (including retention of strength when scratches occur and reduced visibility of such damage)
..., as well as impact resistance and low sensitivity to fingerprints. However, there is no data on the fundamental differences between such glass and regular v3.
- Gorilla Glass v4. Version released in 2014. A key feature is that the design of this coating focused on impact resistance (whereas previous generations focused primarily on scratch resistance). As a result, the glass turned out to be twice as strong as in version 3, despite the fact that its thickness was only 0.4 mm.
- Gorilla Glass v5. An improvement to the "gorilla" released in 2016 that aims to further improve impact resistance. According to the developers, the v5 glass turned out to be 1.8 times stronger than its predecessor; it remained intact in 80% of drops from a height of 1.6 m “face down” onto a rough surface.
- Gorilla Glass v6. Version introduced in 2018. This coating claims to have a 2-fold increase in strength compared to its predecessors, as well as the ability to withstand multiple drops on a hard surface (in tests, v6 glass successfully withstood 15 drops from a height of 1 m).
- Gorilla Glass v7. Gorilla Glass v7 provides reliable protection for your laptop screen from impacts, drops and scratches. This generation promises an increase in drop resistance by approximately 150%, and scratch resistance by as much as 200%.
- Gorilla Glass DX. A version originally created for smart watches and other compact gadgets; It is extremely rare among laptops - in some “2-in-1” models. It was introduced in 2018 along with Gorilla Glass v6. The key improvements in this version include, in particular, increased anti-reflective properties and an increase in the contrast level of the visible image by 50%; the latter, among other things, makes it possible to reduce the actual brightness and, accordingly, the power consumption of screens without compromising image quality.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.
