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.
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).
Adaptive-Sync
Laptop screen support for
VESA Adaptive-Sync technology.
The feature aims to synchronize the refresh rate of the display with the frame rate of the GPU to reduce latency, minimize artifacts, and eliminate visual tearing in the image. Adaptive-Sync-certified screens should run at refresh rate of 120Hz by default, and the frame rate should be able to drop to 60Hz. The actual response time of such displays should be less than 5 ms.
It is important to note that VESA Adaptive-Sync technology is only available for DisplayPort 1.2a or higher.
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”.
RAM type
Laptops mainly use different variants of DDR (so-called double data transfer memory). Here is a list of common types of such memory:
— DDR3. Third generation DDR RAM. Outperforms outdated DDR2 in terms of speed and power efficiency. However, it is also outdated against the background of the fourth version and new items - DDR5.
— DDR3L. A modification of DDR3 memory that supports operation at a reduced voltage - 1.35 V instead of 1.5 V (Low Voltage - hence the index L). Lower voltage contributes to both lower power consumption and better performance. Note that conventional DDR3 memory cannot be installed in such a slot, while the reverse option is quite possible.
—
DDR4. A memory standard released in 2014. Introduced further improvements in speed (up to 25.6 GB / s in the future) and energy efficiency. The most popular among laptops of recent years of release.
—
DDR5. The procession of the fifth generation of the DDR standard began at the turn of 2020-2021. It provides for approximately a twofold increase in memory subsystem performance and increased bandwidth compared to DDR4. Instead of a single 64-bit data channel, DDR5 uses a pair of independent 32-bit channels that work with 16-byte packets and allow 64 bytes of information to be delivered per clock on each channel. New memory modules require a voltage of 1.1 V, and the maximum volume of one DDR5 bar can rea
...ch an impressive 128 GB.
It is worth noting that different types of RAM are not interchangeable.
Some laptops have LPDDR4, LPDDR4X, LPDDR5, LPDDR5X RAM. It was developed by a specialist for mobile devices and is non-expandable, since the corresponding memory modules are built directly into the motherboard. The use of "RAM" standards LPDDR is determined by the achievement of an optimal balance between the performance of the laptop, its size and battery life.Graphics card model
