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.

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).

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.

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).

Max. RAM

The maximum amount of RAM that can be installed on a laptop. It depends, in particular, on the type of memory modules used, as well as on the number of slots for them. Paying attention to this parameter makes sense, first of all, if the laptop is bought with the expectation of and the amount of actually installed memory in it is noticeably less than the maximum available. So laptops can be upgraded in RAM to 16 GB, 24 GB a>, 32 GB, 48 GB, 64 GB and even more - 128 GB.

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.

RAM speed

The clock speed of the RAM installed in the laptop.

The higher the frequency (with the same type and amount of memory) — the higher the performance of RAM in general and the faster the laptop will cope with resource-intensive tasks. However modules with the same frequency may differ somewhat in actual performance due to differences in other characteristics; but this difference becomes significant only in very specific cases, for the average user it is not critical. As for specific values, the most popular modules on the modern market are 2400 MHz, 2666 MHz, 2933 MHz and 3200 MHz. Memory at 2133 MHz or less is found mainly in outdated and low-cost devices, and in high-performance configurations this parameter is 2933 MHz, 3200 MHz, 4266 MHz, 4800 MHz, 5200 MHz, 5500 MHz, 5600 MHz and more.

AMD also offers video cards Radeon 520, Radeon 530(535), Radeon 540X, Radeon 610(625, 630), Radeon RX 550 (550X, 560), Radeon RX 640, Radeon RX 5500M, Radeon RX 6800M and Radeon Pro.

Note that all the above models are discrete. Actually, for a configuration with discrete graphics, it is the model of a separate video adapter that is indicated; if it is supplemented by an integrated module, the name of this module can be clarified by the official characteristics of the processor.

It is also worth mentioning that this paragraph does not give the full name of the model, but only its name within the series (the series itself is given separately - see above). However, knowing the series and model, one can easily find detailed information about the graphics card.
