Screen size
Diagonal size of laptop display.
The larger the screen, the more convenient the laptop for watching high-definition movies, modern games, working with large-format graphic materials, etc. Large screens are especially important for multimedia and gaming models. On the other hand, the diagonal of the display directly affects the size and cost of the entire device. So if portability is key, it makes sense to pay attention to relatively small solutions; especially since most modern laptops have video outputs like HDMI or DisplayPort and allow connection of large-format external monitors.
In light of all this, the actual maximum for laptops these days is
17"(17.3"); however
larger devices (18") reappeared at the beginning of 2023. The standard option for general purpose laptops is
15"(15.6"), less often
16", a diagonal of
13"(13.3") or
14" is considered small by the standards of such And smaller screens can be found mainly in specific compact varieties of laptops — ultrabooks, 2 in 1, transformers, netbooks; among such devices there are solutions for
12 ",
11" and even
10" or less.
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.
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).
Addittional M.2 connectors interface
A connection interface supported by the laptops optional M.2 connector (see above). Recall that this connector is initially free; so this information allows you to evaluate the compatibility with additional components and, accordingly, the possibility of upgrading.
Two main types of interfaces can be implemented through the M.2 connector: SATA and PCI-E. SATA was originally created for hard drives, its support is inexpensive, but the speed of such a connection does not exceed 600 MB / s — this is very low by the standards of SSDs and other modern peripherals. Therefore, in the additional connector (s) M.2, one or another type of PCI-E is most often implemented. This interface has several variations that differ in version, number of lines and, as a result, speed; Here are the options most relevant for modern laptops:
— PCI-E 3.0 2x. Connecting using 2 lanes of PCI-E version 3.0 gives a maximum speed of just under 2 GB / s.
— PCI-E 3.0 4x. Connection using 4 lanes PCI-E version 3.0. Provides a maximum speed of about 4 GB / s.
— PCI-E 4.0 4x. Connected using 4 lanes PCI-E version 4.0, throughput is about 8 Mbps.
— PCI-E. Connection via PCI-E, for which the manufacturer did not specify the details (version and number of lines).
It is worth noting here that in the case of M.2, different versions of PCI-E are quite compatible with each other (except that the speed of work will be limited by the capabilities of the slower side —...the drive or connector). Therefore, even if the specific capabilities of such a connector are not specified, this is generally not critical (these capabilities will not hurt to clarify unless if high performance is fundamentally important to you).
Additional M.2 drive size
The size of an additional slot for a drive (or other peripherals) with an M.2 interface provided in a laptop.
We emphasize that in this case we are not talking about the actually installed drive, but about the size of the bay (recall, there is no drive in it initially — for more details, see "Additional M.2 connector"). Knowing this size, you can estimate the maximum dimensions of the SSD module (or other component) that can fit in this bay. It is worth noting here that the most widespread nowadays are M.2 boards with a width of 22 mm, slots in laptops are usually made for this standard width. Therefore, the main indicator that determines size compatibility is length.
For bays on laptop motherboards, the length is most often 80 mm (marking 22x80 mm). This allows you to install 22 mm M.2 boards with a length of 80 mm, 60 mm, 42 mm and 30 mm — that is, all types of such boards, except for the largest, at 110 mm. The latter, however, is not a disadvantage, since 110-mm components are rarely used in laptops. If there are several additional (free) M.2 slots and they differ in size, these data are also specified in this paragraph, for example, “22x80 / 22x42 mm”.
Additional keys
The number of additional keys provided on the laptop keyboard.
Additional are called keys that do not belong to the standard set and perform various specific functions: calling the browser, controlling the media player, switching power and cooling modes, etc. Such equipment facilitates quick access to certain settings and applications. On the other hand, additional keys require additional space, and there is not much of it in laptops; in addition, some specific functions can be implemented through the Fn key, pressed simultaneously with one of the standard buttons. Therefore, this function is relatively rare in modern laptops, mainly among gaming models.
Weight
The total weight of the laptop — the device itself, without additional accessories (wires and power supply, mice, bags, etc.). For 2 in 1 models (see "Type"), the weight is indicated when assembled, with a keyboard connected.
Nowadays, models weighing
less than 1 kg are found even among fairly large devices — 14 – 15 ", not to mention smaller solutions. Laptops weighing
1 – 1.4 kg are also considered very light,
1.4 – 1.7 kg — light, weight
from 1.7 to 2.1 kg(more precisely, even up to 2.5 kg) can be called average,
up to 3.5 kg — more than average, and a mass of
more than 3.5 kg means that this is an advanced gaming or multimedia laptop designed primarily for power, not portability.
It is also worth remembering that when assessing the weight, the diagonal (size) of the device must also be taken into account. For example, 1.7 kg for a 13" laptop is a lot, and a 17" model can be considered very light if its weight does not reach 2.1 kg.
