Colour gamut (NTSC)
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.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).
SuperPI 1M
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).
3DMark06
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.
M.2 drive interface
The connection interface used by the M.2 SSD installed in the laptop (see "Drive type").
One of the features of the M.2 connector and drives for it is that they can use two different connection interfaces: PCI-E (in one form or another) or SATA. We emphasize that this paragraph indicates the data of the SSD module; the connector itself may provide other interface options, including more advanced ones — see "M.2 connector interface" (for example, a drive with a PCI-E 3.0 2x connection can be placed in a connector that also supports the faster PCI-E 4.0 4x). However, anyway, the connection connector usually allows you to realize all the features of the installed drive; so this item allows you to quite reliably evaluate the capabilities of the standard M.2 module.
As for specific interfaces, nowadays you can mainly find the following options:
— SATA 3. The SATA interface was originally designed for traditional hard drives. The third version of this interface is the latest; it provides data transfer rates up to 600 Mbps. This is significantly less than PCI-E, and in general, very little by the standards of SSD drives. Therefore, M.2 connection using SATA is typical mainly for low-cost entry-level modules. However, even these media are generally faster than most HDDs.
— PCI-E. Universal interface for connecting internal peripherals. Provides generally faster speeds than SATA, making it better suited for SSD modules: theoretically, PC
...I-E allows you to realize the full potential of SSDs, even the fastest. In fact, the supported data transfer rate may be different — depending on the version of the interface and the number of lines (data transmission channels). Here are the options most relevant for modern laptops:
- PCI-E 3.0 2x. Connection using 2 lanes PCI-E version 3.0. This version provides speeds of about 1 GB/s per line; respectively, two lines give a maximum 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. Connection using 4 lanes PCI-E version 4.0. In this version, the throughput, compared to PCI-E 3.0, has been doubled — thus, 4 lines give a maximum speed of about 8 MB / s.
Note that in the case of M.2 connectors, different PCI-E variations are usually quite compatible with each other — except that the connection speed when working with a "non-native" connector will be limited by the capabilities of the slowest component. For example, when connecting a PCI-E 3.0 4x SSD module to a PCI-E 3.0 2x slot, this speed will correspond to the capabilities of the connector, and when connected to PCI-E 4.0 4x, to the capabilities of the drive.Additional 2.5" slot
The presence in the laptop of an additional compartment for an internal drive of the form factor 2.5 ".
Usually, to install or remove a drive in such a bay, it was not necessary to disassemble the entire laptop — just remove the cover or remove the plug. As for 2.5", this is the traditional form factor for hard drives (HDD) for "laptop" purposes, although other types of media (SSD and SSHD — see "Media Type") can be produced in this format. For connection 2.5 "storage drives normally use the SATA connector — it is not as fast as more modern standards like M.2 PCI-E (see "Drive Interface"), however, it is cheaper, and for HDD this connector is quite enough.
Thus, the
presence of an additional 2.5" bay allows you to quickly and cost-effectively increase the total volume of laptop drives.
Connection ports
Connection connectors provided in the design of the laptop.
This paragraph mainly indicates data on video outputs:
VGA,
HDMI(versions 1.4,
2.0,
2.1 and their varieties),
miniHDMI /
microHDMI,
DisplayPort,
miniDisplayPort). In addition, the presence of other types of connectors can be specified here: audio
S / P-DIF, service
COM port. But information about interfaces such as full-sized USB, USB-C, Thunderbolt and LAN is provided in separate paragraphs (see below).
— VGA. Analogue video output, also known as D-Sub 15 pin. Technically considered obsolete: it has low noise immunity, does not provide sound transmission, and the maximum supported resolution in fact does not exceed 1280x1024. However, VGA inputs are still quite common in monitors today, and are also found in other types of video equipment — in particular, projectors. Therefore, some modern laptops, mainly for multimedia purposes, are equipped with similar outputs — counting on connection to the mentioned video devices.
— HDMI. The most popular modern interface for working with HD content. Uses digital data transmission, allows you to transmit high-def
...inition video and multi-channel audio over one cable at the same time. Most modern monitors, TVs, projectors, and other HD-enabled video equipment have at least one HDMI input; so outputs of this type are extremely common in modern laptops.
— microHDMI and miniHDMI. Reduced varieties of the HDMI described above: they are completely similar in functionality and differ only in the size of the connector. They are installed mainly in the thinnest and most compact laptops, for which full-size HDMI is too cumbersome.
The HDMI and mini/microHDMI ports on modern laptops may correspond to different versions:
- v 1.4. The earliest of the commonly used standards, released in 2009. Allows you to transmit a signal in resolutions up to 4096x2160 at a frame rate of 24 fps, and with Full HD resolution, the frame rate can reach 120 fps; 3D video transmission is also possible.
- v 1.4a. The first addition to version 1.4, in which, in particular, two additional 3D video formats were added.
- v 1.4b. The second update of the HDMI 1.4 standard, which introduced only minor clarifications and additions to the v 1.4a specifications.
- v2.0. Global HDMI update introduced in 2013. Also known as HDMI UHD, it allows you to stream 4K video at frame rates up to 60 fps. The number of audio channels can reach 32, and up to 4 audio streams can be broadcast simultaneously. In addition, support for the 21:9 aspect ratio and some improvements regarding 3D content have been introduced.
- v2.0a. First HDMI 2.0 update. A key innovation was compatibility with HDR content (see "HDR support").
- v2.0b. Second update of version 2.0. Key innovations have affected mainly work with HDR — in particular, support for HDR10 and HLG has been added.
- v2.1. One of the newest versions, released in the fall of 2017. Further increases in bandwidth have made it possible to support 4K and even 8K video at frame rates up to 120 fps. In addition, key improvements include enhanced HDR capabilities. Note that to use the full capabilities of HDMI v2.1, HDMI Ultra High Speed cables are required, although basic functions are available with regular cables.
— Display port. Digital high-speed port, allows you to transfer both video and audio in HD quality. It is similar in many respects to HDMI, provides a higher data transfer rate and allows the use of longer cables, but is less common, mainly used in computer technology.
— miniDisplayPort. A smaller version of the DisplayPort described above, designed to make the connector more compact; except for the dimensions, it is no different from the original interface. Some time ago it was a regular video connector for Apple laptops; and even the Thunderbolt interface that replaced it, in versions 1 and 2 (see below), uses a connector identical to the miniDisplayPort connector.
Both full-size DisplayPort and its smaller version may be different versions. Here are the most popular options today:
- v 1.2. The earliest version common in laptops, released in 2010. Among the most important innovations presented in this version are 3D support, the ability to work simultaneously with several video streams for serial connection of screens (daisy chain), as well as the ability to work through the miniDisplayPort connector. Bandwidth v 1.2 is enough to fully support 5K video at 30 frames per second and 8K video — with certain limitations.
- v 1.2a. Update version 1.2, released in 2013. One of the most noticeable innovations is the ability to work with AMD FreeSync (see above). Bandwidth and supported resolutions remain unchanged.
- v 1.3. DisplayPort version released in 2014. Compared to the previous version, the throughput has been increased by 1.5 times for 1 line and almost 2 times for the whole connector (8.1 Gbps and 32.4 Gbps, respectively). This, among other things, made it possible to provide full support for 8K video at 30 fps, as well as increase the maximum frame rate in 4K and 5K standards to 120 and 60 fps, respectively. In daisy chain mode, this standard makes it possible to work with two 4K UHD (3840x2160) screens at a frame rate of 60 Hz, or with four 2560x1600 screens at the same frequency. In addition, Dual-mode support was introduced in this version, providing compatibility with HDMI and DVI interfaces through the simplest passive adapters.
- v 1.4. Version introduced in March 2016. Bandwidth, compared to the previous standard, remained unchanged, but some important features were added — in particular, support for Display Stream Compression 1.2 compression, HDR10 standard and Rec. 2020, and the maximum number of supported audio channels has increased to 32.
- v 1.4a. An update released in 2018 "quietly" — without even an official press release. The main innovation was the update of Display Stream Compression technology from version 1.2 to version 1.2a.
— S/P-DIF. Output for digital audio transmission, including multi-channel. It has two varieties — optical and electrical; the first is absolutely insensitive to interference, but uses rather delicate cables, the second does not require special care in handling, but can be subject to pickups (although the wires are usually made shielded). Laptops use mainly optical S/P-DIF, while for compactness this connector is combined with a mini-Jack jack for connecting headphones. However, anyway, it's ok to clarify the specific features of this interface separately.
— COM port. Universal interface for connecting various external devices — in particular, dial-up modems — as well as for direct connection between two computers. Also known as RS-232 (after the connector). Nowadays it is considered obsolete due to the spread of more compact, faster and more functional interfaces, primarily USB. However, many types of equipment, including specialized ones, use the COM port as a control interface. Such equipment includes uninterruptibles, satellite receivers and communication devices, security and alarm systems, etc. Thus, COM ports, although almost never used in consumer-level laptops, are still found in some specialized models.DisplayPort version
— DisplayPort 1.4b. Interface for connecting external displays with resolutions up to 8K. Each of the four DisplayPort 1.4b lanes is up to 8.1 Gbps, each serving a specific segment of the display. Compared to version 1.4a, the Selective Update protocol has been changed, which simplifies the interface circuitry and reduces the capacity of the temporary frame buffer.
