Comparison HP Pavilion 15-cw1000 [15-CW1008UA 8BP47EA] vs Acer Swift 3 SF314-41G [SF314-41G-R267]

General device type.

In addition to traditional laptops, nowadays you can find varieties such as netbooks, ultrabooks, 2 in 1 tablet laptops and transformers. Here are their main features:

— A laptop. Laptops of a more or less traditional format that do not belong to any of the specific categories described below. The classic, most popular screen size in these models is 15.6 ". 13.3" and 14" laptops are considered compact, laptops with a 17.3" screen are large-format, and larger displays are found in advanced gaming models. At the same time, devices from this category are also very diverse in terms of characteristics and capabilities: they range from “typewriters” designed for education and home tasks, to high-end gaming solutions, and workstations and multimedia complexes.

— Ultrabook. High-end laptops that combine compactness, light weight and advanced features. The diagonal in ultrabooks ranges from 11 "to 14", the thickness of the case does not exceed 21 mm, while the internal equipment usually includes powerful processors, a large amount of RAM, fast drives like SSD and other similar solutions. In addition, many devices from this category are made in a characteristic stylish design and are also designed for...the role of fashion accessories.

— Transformer 360°. Another type of laptop that can turn into a tablet. However, unlike the laptops-tablets described above, in this case, not a removable keyboard is used, but a special swivel connection of the upper and lower blocks. The design of this connection is such that the top of the device can be rotated 360° and placed face up on the keyboard. Thus, the transformer can be converted from a laptop to a tablet without removing the bottom half; this is the fundamental difference between such models and the “2-in-1” described above. This format of work is generally more convenient — no need to look for a place for the removed keyboard, there is no risk of forgetting or losing it; in addition, the mounting design usually allows you to use the device in the format of a “photo frame” — an inclined tablet on a stand without a keyboard. Thus, transformers have become more widespread today than collapsible laptops-tablets. Their disadvantages include the inability to reduce weight by removing the keyboard. The diagonal of such devices can be from 12" to 17".

— 2 in 1 (laptop-tablet). Laptops that can turn into tablets. In such models, the entire “hardware” (or at least its key components) is placed in the upper half, the screen is made touch-sensitive, and the lower half with the keyboard can be completely separated. From traditional tablets, which can also be equipped with keyboards, such devices differ in three main points. The first is more powerful hardware: in particular, most 2-in-1 models carry full-fledged laptop processors (up to and including Core i7), while tablets mainly use CPUs similar to smartphone chips. The second point is a larger screen size, usually 13 – 15". The third caveat is that the keyboard of a laptop-tablet can include not only a set of keys and a spare battery, but also some system components: a discrete graphics card, an additional drive, etc. .
In general, 2-in-1 models are more versatile than traditional laptops; however, nowadays they are much less common than another similar type of laptop — transformers (see below). This is due to the fact that the removable keyboard is not always convenient: when using a device in tablet format, it usually has to be removed; it is not always possible to find a place nearby for the removed keyboard; besides, it can be forgotten or lost through inattention. However, this design also has advantages: for example, if there is enough tablet on the road, there is no need to carry additional cargo in the form of the lower half of the device.

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.

— 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.

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 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.

The total number of slots for RAM modules provided in the laptop; in fact — the maximum number of slats that can be installed simultaneously in this model.

Features for upgrading RAM directly depend on this indicator. So, in low-cost models, there is often only 1 slot, and the only upgrade option is to replace the "native" bar. In more advanced devices, two or even four slots may be provided, while some of them may be free in the initial configuration.

A special case is embedded RAM; it is more compact and cheaper than removable modules, but does not imply replacement at all. At the same time, in some laptops, the “RAM” is only built-in, in others it can be supplemented with one or even two slots for interchangeable strips.

— Integrated(built-in). Video cards that do not have their own memory and use the general system RAM during operation. In modern laptops, such video cards are usually part of the processor. Their main advantages are low cost and power consumption, as well as low heat generation. However, the performance of integrated graphics is noticeably lower than that of discrete graphics, and besides, at high loads it “eats” a significant part of the RAM, which negatively affects the overall system performance. Integrated graphics will be perfect for lighter tasks like document work, web surfing, and light gaming, but for more serious applications, more advanced solutions are worth choosing (see below).

— Discrete. Graphics card as a separate module with its own processor and specialized memory dedicated exclusively to video processing. Such graphics are more expensive than integrated ones, but they significantly outperform them in terms of performance. In addition, even at high loads, it does not take up the total RAM, and some laptops are even able to allocate part of the video memory in addition to RAM if the graphics card is idle. So if you want to play modern games at least at medium settings, or plan to use a laptop for "heavy" graphic tasks like video editing or 3D design, you should definitely choose a model with discrete graphics (or one of its advanced options — Dual Graphics or SLI/Crossfire, see bel...ow).
It is worth noting that most models with such video cards also have a built-in graphics core in the processor. So discrete graphics in modern laptops most often work in hybrid mode: an integrated module is used for simple tasks, and when the load increases, the system switches to discrete graphics.

— Dual Graphics. AMD proprietary technology used in systems equipped with Fusion integrated graphics processors and discrete Radeon graphics cards (originally stated to be compatible with the Radeon 6000 series). The difference between this mode and discrete graphics with automatic switching (see above) is that both video adapters are used not in turn, but simultaneously. Thus, their capacities are combined, which provides a significant increase in video performance. At the same time, Dual Graphics provides ample features for choosing a combination of processors and video cards, because. allows you to combine video cores with different operating frequencies without sacrificing a faster one. The main disadvantage of this technology is the inability to work with Direct X below version 10.

— SLI/CrossFire. Initially, SLI and CrossFire are proprietary technologies used by nVidia and AMD, respectively, to combine the power of several discrete graphics cards. This allows for very high graphics performance. On the other hand, installing several video adapters (even compact ones) in a laptop is associated with serious difficulties: such equipment significantly increases the dimensions of the case and significantly increases power consumption, not to mention the cost. As a result, there are very few laptops with SLI / Crossfire nowadays, and they all belong to the top gaming solutions.

GeForce graphics cards from NVIDIA: RTX represented by RTX 2060, RTX 2060 Max-Q, RTX 2070, RTX 2070 Max-Q, RTX 2070 Super, RTX 2070 Super Max-Q, RTX 2080, RTX 2080 Max-Q, RTX 2080 Super, RTX 2080 Super Max-Q, RTX 3050, RTX 3050 Ti, RTX 3060, RTX 3060 Max-Q, RTX 3070, RTX 3070 Max-Q, RTX 3070 Ti, RTX 3080, RTX 3080 Ti, RTX 4050, RTX 4060, R TX 4070, RTX 4080, RTX 4090 ; MX1xx represented by MX110, MX130 and MX150, MX2xx(MX230 and MX250), MX3xx(MX330 and MX350), MX450, GTX which represent GTX 1050, GTX 1060, GTX 1060 Max-Q, GTX 1070, GTX 1070 Max-Q, GTX 1080, GTX 1080 Max-Q, GTX 1650, GTX 1650 Max-Q, GTX 1650 Ti, GTX 1660 Ti, GTX 1660 Ti Max-Q and.

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.

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.
