Note that all the above models are discrete. Actually, for a configuration with discrete graphics, it is the model of a separate video adapter that is indicated; if it is supplemented by an integrated module, the name of this module can be clarified by the official characteristics of the processor.
It is also worth mentioning that this paragraph does not give the full name of the model, but only its name within the series (the series itself is given separately - see above). However, knowing the series and model, one can easily find detailed information about the graphics card.
Video memory
The amount of native video memory installed in the laptop's graphics card. Only discrete video adapters and their advanced varieties like SLI or Dual Graphics have such memory (see "Video card type").
The more memory, the more powerful the graphics card and the better it can handle complex graphics. Of course, the specific capabilities of the adapter depend on a number of other parameters (primarily the characteristics of the graphics processor); however, the difference in the amount of memory, as a rule, is quite consistent with the difference in the overall level. In terms of specific numbers, solutions with
2 GB are entry-level,
4 GB and
6 GB are intermediate, and
8 GB - to advanced, and
12 GB and
16 GB can be found in top-end gaming laptops and high-end workstations.
GPU TDP
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.
VR
Support
for virtual reality technologies with a laptop graphics card.
This marking means that the video adapter is optimized for use with virtual reality glasses and helmets. The most popular way to use such devices is games, so most laptops with VR support are gaming models. However, this feature can also be useful for more “serious” tasks – from the development of VR applications to scientific, educational and even medical projects.
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.
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”.
Battery capacity
The capacity of the complete laptop battery in watt-hours.
Higher capacity allows the laptop to work longer on a charge, all other things being equal. However, keep in mind that the actual battery life will depend not only on the characteristics of the battery, but also on the power consumption of the laptop itself — and it is determined by both hardware characteristics and installed software. Therefore, only models with similar characteristics can be compared with each other according to this indicator. And if you need a
“long-playing” laptop, you should choose it not by battery capacity, but by directly stated operating time.
As for watt hours, this is a less popular unit of capacity than milliamp hours, but more physically correct: it accurately describes the amount of energy stored by a battery. Thanks to this, in terms of capacity in Wh, it is possible to compare batteries with different nominal voltages (whereas this is not allowed for mAh — additional calculations must be carried out using special formulas). At the same time, Wh can be easily converted to mAh if the battery voltage is known: for this, the capacity in Wh must be divided by the voltage and multiplied by 1000.
Operating time
Maximum laptop operating time on a single battery charge, without recharging. In this case, usually, the operating time in the maximum energy saving mode is implied: disabled wireless modules, minimum screen brightness, a small load on the processor, etc. Accordingly, the time of actual work on a charge is usually noticeably less than this indicator. Nevertheless, it can be used both for a general assessment of the battery life of a laptop, and for comparing it with other models. And choose work laptop (
from 7 operation hours) or
with more powerful battery (from 11 operation hours).
