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.
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).
3DMark06
The result shown by the laptop processor in 3DMark06.
This test is primarily focused on testing performance in games — in particular, the ability of the processor to process advanced graphics and artificial intelligence elements. Test scores are reported as scores; the higher this number, the higher the performance of the tested chip. Good 3DMark06 results are especially important for
gaming laptops.
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).
GPU TDP
The amount of heat generated by the graphics processing unit (GPU) during normal operation. TDP is expressed in watts. It allows you to evaluate the thermal characteristics of a laptop and determine its potential for working with high graphics loads. The higher the GPU TDP value, the more power the GPU consumes, which may require a more efficient cooling system to avoid overheating and ensure stable operation of the device. Laptops with higher GPU heat dissipation are better suited for gamers or graphics and video production professionals.
Backlight
The presence of
a backlight in the laptop keyboard. This feature not only gives the device a stylish look, but also makes the keys more visible than on
non-backlit laptops. The specific implementation of the backlight may vary - it depends both on the price category and on the general purpose of the laptop. For example, single-colour lighting is found in both inexpensive laptops and professional ultrabooks. And gaming models may provide
advanced RGB backlighting and even the ability
to synchronize the backlight.
The backlight colour is usually chosen by the manufacturer taking into account the general specialization of the laptop. Thus,
white backlighting is popular in
“office” devices - it fits well into a restrained business style and at the same time looks good on its own.
Yellow (golden) colour is noticeably less common - mainly among
fashion laptops, although there are exceptions. In turn, among gaming models the most advanced type of backlighting is often found - RGB: it allows you to choose the shade as you wish, and besides, a change in colour can signal different gaming and system events. A number of top gaming laptops feature multi-zone RGB backlighting - each zone can be illuminated indiv
...idually or in combination with other areas of the keys. One of the simplest options is a 3-zone backlight highlighting the “WSAD” keys and another additional area. A more advanced implementation is the 4-zone RGB backlighting of the keyboard, and the most chic is the 24-zone backlighting or even customizable backlighting for each individual key, visually distinguishing the buttons from others. Gaming devices are also produced with simpler, single-colour backlighting systems - in such cases, the keyboards usually glow red, green or blue. It is these shades that are best combined with the characteristic design of gaming laptops; Moreover, the red glow is usually used in devices with a rather catchy and “aggressive” appearance (and in itself is an important element of such a style), while blue and green are typical for a more restrained design.Battery capacity
The capacity of the included laptop battery in milliamp-hours (mAh).
Higher capacity allows the laptop to work longer on a charge, all other things being equal. However, keep in mind that the actual battery life will depend not only on the battery, but also on the power consumption of the laptop itself — and it is determined by both the hardware platform and the installed software. Therefore, only models with similar characteristics can be compared with each other according to this indicator. And if you need a
“long-playing” laptop or
laptop with very good battery life, you should choose it not by battery capacity, but by directly stated operating time.
Regarding milliamp hours, it is also worth noting that this is not a very reliable (although the most popular) unit of capacity: the actual amount of energy stored in a battery depends not only on milliamp hours, but also on the operating voltage. A more correct unit in this sense is watt-hours, for details on them, see p. "Battery capacity" below. As for specific numbers, the most modest models in this regard are equipped with batteries of
3000 – 4000 mAh and even
less.
4000 – 5000 mAh can be called an average,
5000 – 6000 mAh is above average, and the most capacious laptop batteries can hold
6000 -7000 mAh or
more.
