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.
Colour gamut (NTSC)
The colour gamut of the laptop matrix according to the NTSC 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.
Specifically, NTSC is one of the first colour models created back in 1953 for colour television. It is not used in the production of modern LCD matrices, but is used to describe and compare them. NTSC covers a wider range of colours than sRGB, which is standard in computer technology; therefore, even a small number of percentages in this case corresponds to a fairly wide coverage. For example, a value of
72% or more in NTSC is already considered a good value for use in design and graphics. At the same time, the same NTSC figures on different screens may correspond to different sRGB figures; so if accurate colour reproduction is decisive for you, these details should be clarified before buying.
Also note that among individual monitors, it is easier to find a screen with a wide colour gamut; while it will also cost less than a laptop with similar display characteristics. So choosing a laptop with a h
...igh-end screen makes sense mainly when portability is as important to you as high-quality colour reproduction.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.
Code name
The code name for CPU installed in the laptop.
This parameter characterizes, first of all, the generation to which the processor belongs, and the microarchitecture used in it. At the same time, chips with different code names can belong to the same microarchitecture/generation; in such cases, they differ in other parameters - general positioning, belonging to certain series (see above), the presence / absence of certain specific functions, etc.
Nowadays, the following code names are relevant in Intel processors:
Coffee Lake,
Comet Lake,
Ice Lake,
Tiger Lake,
Jasper Lake,
Alder Lake,
Raptor Lake (13th Gen),
Alder Lake-N,
Raptor Lake (14th Gen),
Meteor Lake (Series 1),
Raptor Lake (Series 1),
Lunar Lake (Series 2).
For AMD, the list looks like this:
Zen 2 Renoir,
Zen 2 Lucienne,
Zen 3 Cezanne,
Zen 3 Barcelo,
Zen 3+ Rembrandt,
Zen 3+ Rembrandt R,
Zen 2 Mendocino,
Zen 3 Barcelo R,
Zen 4 Dragon Range,
Zen 4 Phoenix
Zen 4 Hawk Point,
Zen 5 Strix Point.
Detailed data on different code names can be found in special sources.
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).
Graphics card type
—
Integrated(built-in). Video cards that do not have their own memory and use the general system RAM during operation. In modern laptops, such video cards are usually part of the processor. Their main advantages are low cost and power consumption, as well as low heat generation. However, the performance of integrated graphics is noticeably lower than that of discrete graphics, and besides, at high loads it “eats” a significant part of the RAM, which negatively affects the overall system performance. Integrated graphics will be perfect for lighter tasks like document work, web surfing, and light gaming, but for more serious applications, more advanced solutions are worth choosing (see below).
—
Discrete. Graphics card as a separate module with its own processor and specialized memory dedicated exclusively to video processing. Such graphics are more expensive than integrated ones, but they significantly outperform them in terms of performance. In addition, even at high loads, it does not take up the total RAM, and some laptops are even able to allocate part of the video memory in addition to RAM if the graphics card is idle. So if you want to play modern games at least at medium settings, or plan to use a laptop for "heavy" graphic tasks like video editing or 3D design, you should definitely choose a model with discrete graphics (or one of its advanced options — Dual Graphics or SLI/Crossfire, see bel
...ow).
It is worth noting that most models with such video cards also have a built-in graphics core in the processor. So discrete graphics in modern laptops most often work in hybrid mode: an integrated module is used for simple tasks, and when the load increases, the system switches to discrete graphics.
— Dual Graphics. AMD proprietary technology used in systems equipped with Fusion integrated graphics processors and discrete Radeon graphics cards (originally stated to be compatible with the Radeon 6000 series). The difference between this mode and discrete graphics with automatic switching (see above) is that both video adapters are used not in turn, but simultaneously. Thus, their capacities are combined, which provides a significant increase in video performance. At the same time, Dual Graphics provides ample features for choosing a combination of processors and video cards, because. allows you to combine video cores with different operating frequencies without sacrificing a faster one. The main disadvantage of this technology is the inability to work with Direct X below version 10.
— SLI/CrossFire. Initially, SLI and CrossFire are proprietary technologies used by nVidia and AMD, respectively, to combine the power of several discrete graphics cards. This allows for very high graphics performance. On the other hand, installing several video adapters (even compact ones) in a laptop is associated with serious difficulties: such equipment significantly increases the dimensions of the case and significantly increases power consumption, not to mention the cost. As a result, there are very few laptops with SLI / Crossfire nowadays, and they all belong to the top gaming solutions.
