Comparison Lenovo LOQ 15ARP9 [83JC007KUS] vs Asus TUF Gaming A15 2023 FA507NUR [FA507NUR-LP016W]

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 Adobe RGB 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.

The Adobe RGB colour model was originally developed for print applications; the range of colours covered by it corresponds to the capabilities of professional printing equipment. Therefore, theoretically, the extensive coverage of this model will be useful to those involved in the design and layout of high-end printed products. However most laptop screens have very limited Adobe RGB values, rarely exceeding 74%; however, you can also find high-end models where this figure approaches 100%. Of course, the cost of such laptops will also be appropriate; therefore, it makes sense to pay attention to them, first of all, when the ability to work with colour “on the go” is of key importance. If this is to be done in one place, it may be more justified to buy a separate monitor with a wide colour gamut (especially since a monitor with such characteristics is easier to find than a laptop).

Laptop display certification for safe blue light emission levels and panel flicker rates. The presence of a TÜV Rheinland certificate confirms that the screen is comfortable for the eyes.

TÜV Rheinland is a large international concern headquartered in Cologne, Germany, providing a wide range of audit services. The company's specialists have developed and approved a number of tests for the compliance of the screens of mobile devices, monitors and TVs with the required level of eye protection from the harmful effects of display radiation on the user's vision on the other side of the screen. The authoritative opinion of TÜV Rheinland is respected in the tech community. Certificates from this body are issued to successfully tested electronics for the implementation of blue light filtering and screen flicker suppression technologies.

The amount of heat generated by the graphics processing unit (GPU) during normal operation. TDP is expressed in watts. It allows you to evaluate the thermal characteristics of a laptop and determine its potential for working with high graphics loads. The higher the GPU TDP value, the more power the GPU consumes, which may require a more efficient cooling system to avoid overheating and ensure stable operation of the device. Laptops with higher GPU heat dissipation are better suited for gamers or graphics and video production professionals.

In laptops, the image processed by a discrete video card first passes through the graphics built into the CPU, and only then is transmitted to the display. The MUX Switch on the motherboard of gaming laptop models allows you to choose between using integrated or discrete graphics. One of its advanced varieties is the Advanced Optimus intelligent system, which works in conjunction with video adapters from NVIDIA. It allows you to literally choose on the fly the most suitable GPU for data processing, depending on the intensity of the tasks being performed.

The result shown by the laptop's graphics card in 3DMark06.

This test primarily determines how well a graphics card handles intensive workloads, in particular, with detailed 3D graphics. The test result is indicated in points; the more points, the higher the performance of the video adapter. Good 3DMark06 scores are especially important for gaming laptops and advanced workstations. However, it is difficult to call them reliable, since measurements are made on video cards with different TDPs and an overall average score is given. Thus, your laptop can have either more or less than the specified result - it all depends on the TDP of the installed video card.

The size of the M.2 SSD module (see "Drive Type") installed in the laptop. Specified in the format "width x length".

This parameter primarily allows you to evaluate the amount of space allocated for the drive, and the possibility of replacing it with a module of a different size. It is worth noting here that the M.2 standard itself allows several options for length and width, but boards with a width of 22 mm are most widely used. The length of such a board usually corresponds to one of the standard options: 30 mm, 42 mm, 60 mm, 80 mm and 110 mm.

In general, the installation of a shorter module of the same width (for example, 22x42 mm instead of 22x60 mm) does not cause problems, but the possibility of using larger components should be clarified separately — not every case allows the installation of M.2 drives with a larger one than the standard module , length. As for specific dimensions, the most common in modern laptops is M.2 22x80 mm SSDs: this size is guaranteed to allow you to change the “native” drive to almost any 22 mm standard module (except for the largest, 22x110 mm — and even for them there can be a place ). There are also smaller sizes — 22x60 mm, 22x42 mm and even 22x30 mm — but much less frequently. And here it is worth saying that the shorter the length of the SSD module, the smaller its capacity, usually.

Note that modern laptops also use M.2 modules of a different width — usually 16 mm with a length of 20 mm (16x20 mm). H...owever, this is a very rare option.

The number of additional M.2 connectors on the laptop motherboard.

In this case, any free M.2 connector is called additional (if there is an installed drive, the connector is considered the main one and its characteristics are given above — see "M.2 connector interface" and so on). There may be several such free slots — therefore, our catalog specifies the number of additional M.2 connectors, and not just their presence.

Anyway, this parameter will be useful primarily if the laptop is bought for an upgrade. It allows you to estimate how many M.2 SSDs (or other peripherals with such a connection) can be additionally installed in the device. At the same time, when choosing specific components, you should also take into account the interface and the size of free M.2 slots (see below for more details).

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).
