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).

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.

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).

TurboBoost / TurboCore frequency

Processor clock speed achieved in TurboBoost or TurboCore "overclocking" mode.

Turbo Boost and Turbo Core technologies are used by different manufacturers (Intel and AMD, respectively), but they have the same principle of operation: load distribution from more loaded processor cores to less loaded ones to improve performance. The "overclocking" mode is characterized by an increased clock frequency, and it is indicated in this case.

For more information about clock speed in general, see the relevant paragraph above.

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).

SuperPI 1M

The result shown by the laptop processor in the SuperPI 1M test.

The essence of this test is to calculate the number "pi" to the millionth decimal place. The time spent on this calculation is the final result. Accordingly, the more powerful the processor, the smaller the result will be (this SuperPI 1M is fundamentally different from many other tests).

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.
