Surface treatment

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.

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.

Series

Each series combines chips that are similar in general level, purpose, and often also in individual specific features. Moreover, 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 equipped almost exclusively with processors from AMD or Intel - until in 2020 Apple introduced its own Apple M1 chip (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). At the moment, the following series are mainly relevant in laptops:

-AMD Ryzen 3. The most inexpensive series of AMD chips in the Ryzen family (Ryzen 3, Ryzen 5, Ryzen 7 and Ryzen 9) using the Zen microarchitecture. In terms of the general design, Ryzen 3 is similar to its older brothers, but half of the computing cores are deactivated. However, it is quite advanced and is found even in ultrabooks.

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

— 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 increased, and the L3 cache capacity in Ryzen 7 chips is 16 MB as standard.

– Atom. Processors specifically designed by Intel for mobile devices (including smartphones). They are mainly used in ultra-compact laptops.

— Core M. Processors designed for portable equipment (in particular, ultra-compact laptops) and characterized by extremely low heat generation, allowing the use of passive cooling systems. They were presented in 2014 as the first production chips based on 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 performance to Celeron, but not up to the Core i3. Also carry integrated graphics.

Processor. The entry-level processor line that precedes the Core i3 family in the modern Intel hierarchy. Such chipsets are found in entry-level laptops designed for everyday household or office use, as well as undemanding games.

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

Intel Core i5 / Core 5. A line of mid-class processors - both in general and by the standards of the Core family in particular. Most often, the series processors 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 advent of the i9, it was the most advanced in the Core family, but then it lost the palm to the “nine”. Core 7 chips have at least 4 cores and integrated graphics.

Core i9. Top-level processors released in 2017; the most powerful line of consumer-grade laptop processors at the time of its introduction, displacing Core i7 chips from this position. They have 6 cores and a large 3-level cache.

Core Ultra 5. Transformation of the popular series of mobile processors of the strong mid-range Intel Core i5, which received the Ultra prefix from the end of 2023 - when the Meteor Lake generation of chipsets debuted. The main feature of Core Ultra 5 processors is a separate NPU, which provides 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 a new generation of Meteor Lake chipsets). A neural coprocessor responsible for accelerating the operation of artificial intelligence algorithms has become a mandatory attribute of Ultra models.

Core Ultra 9. A line of the most powerful laptop processors from Intel, released to replace the Core i9 family at the end of 2023. The premiere of models labeled Ultra took place in the generation of Meteor Lake chipsets. 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 along 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), an NVMe solid-state drive and some other components (in in particular, Thunderbolt 4 controllers).

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). 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. Detailed data on different code names can be found in special sources.

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).
