Comparison HP 250 G6 [250G6 2XZ27ES] vs Lenovo IdeaPad 300 15 [300-15ISK 80Q701JERK]

The technology by which the matrix of the laptop is made.

Matrices of the TN+film, IPS and *VA types are most widely used nowadays; less common are screens like OLED, AMOLED, QLED, miniLED, as well as more specific solutions like LTPS or IGZO. Here is a more detailed description of all these options:

— TN-film. The oldest, simplest and most inexpensive technology currently in use. The key advantages of this type of display are low cost and excellent response time. On the other hand, such matrices are not of high image quality: brightness, colour fidelity and viewing angles of TN-film screens are at an average level. These indicators are quite enough for working with documents, web surfing, most games, etc.; however, for more serious tasks that require a high-quality and reliable picture (for example, design or photo / video colour correction), such screens are practically unsuitable. Thus, TN-film matrices are relatively rare nowadays, mainly among low-cost laptops; more advanced devices are equipped with better screens, most often IPS.

— IPS (In-Plane Switching). The most popular type of matrix for laptops in the middle and top price range; however, it is increasingly common in low-cost models, and for trans...formers and 2-in-1 devices (see "Type") it is almost a standard option. Screens of this type are noticeably superior to TN-film in terms of the quality of the “picture”: they provide a bright, reliable and rich image that hardly changes when the viewing angle changes. In addition, this technology allows to achieve extensive colour gamuts in various special standards (see below) and is suitable for creating displays with advanced features such as HDR support or Pantone / CalMAN certification (also see below). Initially, IPS matrices were expensive and had a slow response time; however, nowadays, various modifications of this technology are used, in which these shortcomings are fully or partially compensated. At the same time, different modifications may differ in practical characteristics: for example, some are created based on the maximum reliability of the picture, others differ in affordable cost, etc. So it's ok to clarify the actual characteristics of the IPS screen before buying — especially if you plan to use a laptop for specific applications where image quality is critical.

— *V.A. Various modifications of matrices of the "Vertical Alignment" type: MVA, PVA, Super PVA, ASVA, etc. The differences between these technologies are mainly in the name and the manufacturer. Initially, matrices of this type were developed as a compromise between IPS (high-quality, but expensive and slow) and TN-film (fast, inexpensive, but modest in image quality). As a result, *VA screens turned out to be more affordable than IPS and more advanced than TN-film — they have good colour reproduction, deep blacks and wide viewing angles. At the same time, it is worth noting that the colour balance of the picture on such a display changes somewhat when the viewing angle changes. This makes it difficult to use *VA matrices in professional colour work. In general, this option is designed mainly for those who do not need perfect colour accuracy and at the same time want to see a bright and colorful image.

— OLED. Matrices based on the so-called organic light-emitting diodes. The key feature of such displays is that in them each pixel is a source of light in itself (unlike classic LCD screens, in which the backlight is made separately). This design principle, combined with a number of other solutions, provides excellent brightness, contrast and colour reproduction, rich blacks, the widest possible viewing angles and a small thickness of the screens themselves. On the other hand, laptop OLED matrices for the most part turn out to be quite expensive and “gluttonous” in terms of energy consumption, and they wear out unevenly: the more often and brighter a pixel glows, the faster it loses its working properties (however, this phenomenon becomes noticeable only after several years of intensive use). In addition, for a number of reasons, such screens are considered poorly suited for gaming applications. In light of all this, sensors of this type are rare these days — mostly in individual high-end laptops designed for professional colour work and with appropriate features such as HDR support, wide colour gamut and/or Pantone / CalMAN certification (see below).

— AMOLED. A kind of matrices on organic light-emitting diodes, created by Samsung (however, it is also used by other manufacturers). In terms of its main features, it is similar to other types of OLED matrices (see above): on the one hand, it allows you to achieve excellent image quality, on the other hand, it is expensive and wears out unevenly. At the same time, AMOLED screens have even more advanced colour performance combined with better power optimization. And the low prevalence of this technology is mainly due to the fact that it was originally created for smartphones and only recently began to be used in laptops (since 2020).

— MiniLED. Screen backlight system on a substrate of miniature LEDs with a size of about 100-200 microns (µm). On the same display plane, it was possible to increase the number of LEDs several times, and their array is placed directly behind the matrix itself. The main advantage of miniLED technology can be called a large number of local dimming zones, which in total gives improved brightness, contrast and more saturated colors with deep blacks. MiniLED screens unlock the potential of High Dynamic Range (HDR) technology, suitable for graphic designers and digital content creators.

— QLED. Matrices on "quantum dots" with a redesigned LED backlight system. In particular, it provides the replacement of multilayer colour filters with a special thin-film coating of nanoparticles. Instead of traditional white LEDs, QLED panels use blue ones. As a result, a set of design innovations makes it possible to achieve a higher brightness threshold, colour saturation, improve the quality of colour reproduction in general, while reducing the thickness of the screen and reducing power consumption. The reverse side of the QLED-matrices coin is an expensive cost.

— PLS. A type of matrix developed as an alternative to the IPS described above and, according to some sources, is one of its modifications. Such matrices are also characterized by high colour rendering quality and good brightness; in addition, the advantages of PLS include good suitability for high-resolution screens (due to high pixel density), as well as lower cost than most IPS modifications, and low power consumption. At the same time, the response speed of such screens is not very high.

— LTPS. An advanced type of TFT-matrix, created on the basis of the so-called. low temperature polycrystalline silicon. Such matrices have high colour quality, and are also well suited for screens with high pixel density — in other words, they can be used to create small displays with very high resolution. Another advantage is that part of the control electronics can be built directly into the matrix, reducing the overall thickness of the screen. On the other hand, LTPS matrices are difficult to manufacture and expensive, and therefore are found mainly in premium laptops.

— IGZO. An LCD technology that uses a semiconductor material based on indium, gallium, and zinc oxides (as opposed to more traditional amorphous silicon). This technology provides fast response time, low power consumption and very high colour quality; it also achieves high pixel densities, making it well-suited for ultra-high resolution screens. However, while such displays in laptops are extremely rare. This is explained both by the high cost and by the fact that rather rare metals are used in the production of IGZO matrices, which makes large-scale production difficult.

— Glossy. A glossy surface improves the overall picture quality: other things being equal, the picture on such a screen looks brighter and more colorful than on a matte one. On the other hand, pollution is very noticeable on such a surface, and in bright external lighting, a lot of glare appears on it, which can greatly interfere with viewing. Therefore, instead of the classic gloss, laptops are increasingly using an anti-reflective version of such a coating (see below). Nevertheless, this option still does not lose popularity: it is somewhat cheaper than the “anti-glare”, and in soft, relatively dim lighting, it can even provide a more pleasing image to the eye.

— Matte. Matte finish is inexpensive and does not form glare even from fairly bright lighting. On the other hand, the picture on such a screen is noticeably dimmer than on a similar glossy display. However, this moment can be compensated by various design solutions (primarily a good margin of brightness); so this option can be found in all categories of modern laptops — from low-cost models for working with documents to top gaming configurations.

— Glossy (anti-glare). A variation on the glossy finish described above, designed to reduce glare from external light sources. Such screens really glare noticeably less than traditional glossy ones (or even do not give glare at all); at the same time, in...terms of image quality, they are at least superior to matte ones. So it is this type of coating that is most popular nowadays.

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.

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).

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.

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).

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).

— 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.

A series of video cards installed in a laptop. Different models of video cards within the same series can vary significantly in performance, but their key features are usually the same.

— Intel HD Graphics. Integrated graphics cards, the first solution in the Intel line to be built directly into the processor (before that, integrated graphics were part of the motherboard).

— AMD Radeon. A family of video cards from AMD, used primarily in laptops with processors from the same brand. Includes solutions of various types (integrated and discrete) and level (from low-cost to high-end).

— Qualcomm Adreno. Integrated graphics found in Qualcomm's Snapdragon processors (see "Processor Series"). It is primarily a solution for mobile gadgets, so it does not differ in performance, but it is very efficient in terms of power consumption.

— Apple. Usually, in this case, it means the graphics core built into the Apple M1 processor (see "Processor series"). The first generation of these processors used eight-core (rarely seven-core) integrated GPUs with support for up to 25,000 threads simultaneously.
