Response time

Screen response time to a control signal — in other words, the time between the receipt of such a signal on the matrix and the switching of pixels to a given mode.

Theoretically, the lower the response time, the better the screen handles with dynamic scenes, the higher the frame rate on it can be achieved. At the same time, it is worth noting that almost all modern matrices have sufficient response speed to effectively process the classic frame rate of 60 Hz — and, recall, it is quite enough for most cases. So paying attention to this parameter makes sense, first of all, if you are purchasing an advanced gaming model, the screen of which operates at a frame rate of more than 60 Hz. In other cases, the response time is often not indicated at all.

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.

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.

Processor cores

The number of cores in the laptop CPU.

The core is a part of the CPU designed to process one thread of instructions (and sometimes more, for such models, see "Number of threads"). Nowadays, in laptops you can find dual-core, quad-core, six-core, eight-core, ten-core, 12-core, 14-core CPUs. Also note that recently configurations with different types of cores as part of a single CPU are gaining popularity. Such chips are built on a hybrid architecture that combines high performance and energy-efficient cores. They operate at different clock speeds, have different amounts of pre-installed cache memory and are designed to solve different problems. In particular, such CPUs are found in Intel CPUs (from the 12th generation) and Apple.

Theoretically, more cores means higher performance, especially in parallel computing tasks or when processing multiple resource-intensive tasks at the same time. However, in practice this is true only all else being equal – that is, with a similar microarchitecture, clock frequency, cache volumes and other key parameters. Modern CPUs can vary greatly on these parameters – in itself, a greater number of cores does not mean superiority. This is especially true for dual- and quad-core chips: a mobil...e-level CPU (for example, Snapdragon, see "CPU series") with 4 cores may well be inferior in capabilities to a dual-core desktop series chip (like Core i3 or i5, which are often used in universal laptops with the "optimal" set of specifications for different tasks). When evaluating CPUs with two or four cores, it is necessary to look, first of all, at the general set of characteristics. But the presence of six, eight or more cores is almost certainly a sign of a powerful CPU. Such equipment is typical mainly for advanced gaming and professional laptops.

Total threads

The number of threads supported by the laptop processor.

A thread is a sequence of instructions executed by a processor. Initially, each processor core was designed for one such sequence, and the number of threads was equal to the number of cores. However, in modern CPUs, multithreading technologies are increasingly being used, which allow loading each core with two instruction sequences at once. Such technologies have different names for different manufacturers, but the principle of their operation is the same: during the inevitable pauses in the execution of one of the threads, the kernel does not idle, but works with a different sequence. Accordingly, the total number of threads in such processors is twice the number of cores; such a scheme of work significantly increases productivity (although, of course, it also affects the cost).

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).
