Comparison HP Victus 15-fb0000 [15-FB0016NQ 6M2R2EA] vs Lenovo Ideapad 320 15 [320-15IAP 80XR00VJRA]

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.

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.

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.

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.

Each series combines chips that are similar in general level, purpose, and often also in individual specific features. At the same time, most series include processors of several generations at once, which can differ significantly in actual characteristics. It is worth noting that until recently, laptops were almost exclusively equipped with processors from AMD or Intel - until in 2020, Apple introduced its own chip Apple M1(with updated versions of Apple M1 Pro and Apple M1 Max), Apple M2(2022) with productive chips M2 Pro, M2 Max and Apple M3, M3 Pro, M3 Max(2023). Then Qualcomm entered the arena with its Snapdragon processors.

At the moment, the following series are mainly relevant in laptops:

— AMD Ryzen 3. The cheapest series of AMD chips in the Ryzen family (Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9 and Ryzen AI), using the Zen microarchitecture. In ter...ms of general design, Ryzen 3 is similar to its older brothers, but half of the computing cores are deactivated. Nevertheless, it is quite advanced and is even found in ultrabooks.

— Ryzen 5. The second series on the Zen architecture is a more affordable alternative to the Ryzen 7 chips. Ryzen 5 chips have slightly more limited performance characteristics (in particular, a lower clock frequency and, in some models, L3 cache volume). Otherwise, they are completely similar to the "sevens" and are also positioned as high-performance chips for gaming and workstations. For more details, see "Ryzen 7" below.

— Ryzen 7. The first series of processors from AMD, built on the Zen microarchitecture. It was introduced in March 2017. In general, Ryzen chips (of all series) are promoted as high-end solutions for gamers, developers, graphic designers and video editors. One of the main differences between Zen and previous microarchitectures was the use of simultaneous multithreading, due to which the number of operations per clock was significantly increased at the same clock frequency. In addition, each core received its own floating-point calculation unit, the speed of the first-level cache memory increased, and the L3 cache volume in Ryzen 7 chips is 16 MB by default.

— Ryzen 9. AMD Ryzen 9 processors on the Zen microarchitecture debuted in 2019. The series became the top among all Ryzens, displacing Ryzen 7 from this position. First of all, the CPU line is usually used for professional tasks (design, video editing, 3D rendering), games, streaming and other high-load applications. The first Ryzen 9 models had 12 cores and 24 threads, in later ones this number was increased to 16 and 32, respectively.

— Ryzen AI. The Ryzen series of processors with artificial intelligence was launched in 2024. The first in the lineup was the AMD Ryzen AI 300 subfamily. It introduces the new Zen 5 computing core architecture, has integrated RDNA 3.5 graphics, and a powerful XDNA 2 neural processor with a performance of up to 50 TOPS (trillion operations per second). The Ryzen AI chips are perfect for a wide range of tasks — from everyday work to complex calculations using AI algorithms.

— Atom. Processors specially developed by Intel for mobile devices (including smartphones). Used mainly in ultra-compact laptops.

— Core M. Processors designed for portable devices (in particular, ultra-compact laptops) and featuring extremely low heat generation, allowing the use of passive cooling systems. They were introduced in 2014 as the first serial chips using the 14 nm process technology.

— Celeron. The most budget series in the modern line of desktop processors from Intel. However, the latest generations are equipped with integrated graphics.

— Pentium. Budget desktop processors from Intel, slightly superior in characteristics to Celeron, but not up to the Core i3. Also have integrated graphics.

— Processor. A line of entry-level processors that precedes the Core i3 family in Intel's modern hierarchy. These chipsets are found in entry-level laptops designed for everyday home or office use, as well as undemanding games.

— Intel Core i3 / Core 3. A series of entry-level and mid-range processors, the most budget-friendly in the Core family. However, in terms of characteristics and computing power, the processors of this line are superior to the Pentium and Celeron series (see above).

— Intel Core i5 / Core 5. A line of mid-range processors — both in general and by the standards of the Core family in particular. Most often, the processors of the series contain from 4 to 10 cores, and in terms of performance, they are between the relatively inexpensive i3 (Core 3) and the powerful i7 (Core 7).

— Intel Core i7 / Core 7. A series of high-performance processors from Intel. Before the i9, it was the most advanced in the Core family, but then it gave way to the "nine". Core 7 chips have at least 4 cores and integrated graphics.

— Core i9. Top-end processors released in 2017; the most powerful line of consumer-grade notebook processors at the time of their release, displacing Core i7 chips from this position. They have 6 cores and a large L3 cache.

— Core Ultra 5. A transformation of the popular series of mobile processors of the strong mid-range Intel Core i5, which received the Ultra prefix since the end of 2023 — when the Meteor Lake generation of chipsets debuted. The main feature of the Core Ultra 5 processors is a separate NPU, which gives advantages when working with AI models.

— Core Ultra 7. A pre-top series of high-performance mobile processors from Intel, which replaced the Core i7 family at the end of 2023 (with the advent of the new generation of Meteor Lake chipsets). A mandatory attribute of the Ultra models has become a neural coprocessor, responsible for accelerating the operation of artificial intelligence algorithms.

— Core Ultra 9. The most powerful line of laptop processors from Intel, released to replace the Core i9 family at the end of 2023. The premiere of models with the Ultra addition took place in the Meteor Lake chipset generation. A distinctive feature of Intel Core Ultra 9 is the presence of a separate NPU to improve the efficiency of using artificial intelligence models.

— Apple. A series of processors from Apple, which debuted in November 2020 with the release of the next generations of MacBook, MacBook Air and MacBook Pro. In the initial configurations, they are equipped with 8 cores - 4 productive and 4 economical; the latter, according to the creators, consume 10 times less energy than the former. This, combined with the 5 nm process technology, made it possible to achieve very high energy efficiency and, at the same time, performance. It is also worth noting that the processors of this series are made according to the system-on-chip scheme: a single module combines a CPU, a graphics adapter, RAM (in the first models - 8 or 16 GB), a solid-state NVMe drive and some other components (in particular, Thunderbolt 4 controllers).

— Snapdragon. Snapdragon processors are essentially mobile solutions — they are traditionally installed in smartphones and tablets. Separate lines of Snapdragon chips have been released specifically for laptops (for example, X Elite on ARM architecture). Many laptops based on such processors are equipped with built-in LTE or even 5G modules. Their advantage is also high energy efficiency.

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 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.

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.

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).
