Comparison MSI Thin 15 B12VE [B12VE-1817XPL] vs Acer Nitro V 15 ANV15-51 [ANV15-51-55S5]

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 specific model of the processor installed in the laptop, or rather, the processor index within its series (see above). Knowing the full name of the processor (series and model), you can find detailed information on it (up to practical reviews) and clarify its capabilities.

The code name for CPU installed in the laptop.

This parameter characterizes, first of all, the generation to which the processor belongs, and the microarchitecture used in it. At the same time, chips with different code names can belong to the same microarchitecture/generation; in such cases, they differ in other parameters - general positioning, belonging to certain series (see above), the presence / absence of certain specific functions, etc.

Nowadays, the following code names are relevant in Intel processors: Coffee Lake, Comet Lake, Ice Lake, Tiger Lake, Jasper Lake, Alder Lake, Raptor Lake (13th Gen), Alder Lake-N, Raptor Lake (14th Gen), Meteor Lake (Series 1), Raptor Lake (Series 1), Lunar Lake (Series 2), Arrow Lake (Series 2). For AMD, the list looks like this: Zen 2 Renoir, Zen 2 Lucienne, Zen 3 Cezanne, Zen 3 Barcelo, Zen 3+ Rembrandt, Zen 3+ Rembrandt R, Zen 2 Mendocino, Zen 3 Barcelo R, Zen 4 Dragon Range, Zen 4 Phoenix Zen 4 Hawk Point, Zen 5 Strix Point, Zen 5 Strix Halo. Detailed data on different code names can be found in special sources.

Processor clock speed achieved in TurboBoost or TurboCore "overclocking" mode.

Turbo Boost and Turbo Core technologies are used by different manufacturers (Intel and AMD, respectively), but they have the same principle of operation: load distribution from more loaded processor cores to less loaded ones to improve performance. The "overclocking" mode is characterized by an increased clock frequency, and it is indicated in this case.

For more information about clock speed in general, see the relevant paragraph above.

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).

The maximum amount of RAM that can be installed on a laptop. It depends, in particular, on the type of memory modules used, as well as on the number of slots for them. Paying attention to this parameter makes sense, first of all, if the laptop is bought with the expectation of and the amount of actually installed memory in it is noticeably less than the maximum available. So laptops can be upgraded in RAM to 16 GB, 24 GB a>, 32 GB, 48 GB, 64 GB and even more - 128 GB.

Laptops mainly use different variants of DDR (so-called double data transfer memory). Here is a list of common types of such memory:

— DDR3. Third generation DDR RAM. Outperforms outdated DDR2 in terms of speed and power efficiency. However, it is also outdated against the background of the fourth version and new items - DDR5.

— DDR3L. A modification of DDR3 memory that supports operation at a reduced voltage - 1.35 V instead of 1.5 V (Low Voltage - hence the index L). Lower voltage contributes to both lower power consumption and better performance. Note that conventional DDR3 memory cannot be installed in such a slot, while the reverse option is quite possible.

— DDR4. A memory standard released in 2014. Introduced further improvements in speed (up to 25.6 GB / s in the future) and energy efficiency. The most popular among laptops of recent years of release.

— DDR5. The procession of the fifth generation of the DDR standard began at the turn of 2020-2021. It provides for approximately a twofold increase in memory subsystem performance and increased bandwidth compared to DDR4. Instead of a single 64-bit data channel, DDR5 uses a pair of independent 32-bit channels that work with 16-byte packets and allow 64 bytes of information to be delivered per clock on each channel. New memory modules require a voltage of 1.1 V, and the maximum volume of one DDR5 bar can rea...ch an impressive 128 GB.

It is worth noting that different types of RAM are not interchangeable.

Some laptops have LPDDR4, LPDDR4X, LPDDR5, LPDDR5X RAM. It was developed by a specialist for mobile devices and is non-expandable, since the corresponding memory modules are built directly into the motherboard. The use of "RAM" standards LPDDR is determined by the achievement of an optimal balance between the performance of the laptop, its size and battery life.

The clock speed of the RAM installed in the laptop.

The higher the frequency (with the same type and amount of memory) — the higher the performance of RAM in general and the faster the laptop will cope with resource-intensive tasks. However modules with the same frequency may differ somewhat in actual performance due to differences in other characteristics; but this difference becomes significant only in very specific cases, for the average user it is not critical. As for specific values, the most popular modules on the modern market are 2400 MHz, 2666 MHz, 2933 MHz and 3200 MHz. Memory at 2133 MHz or less is found mainly in outdated and low-cost devices, and in high-performance configurations this parameter is 2933 MHz, 3200 MHz, 4266 MHz, 4800 MHz, 5200 MHz, 5500 MHz, 5600 MHz, 6000 MHz, 6400 MHz and more.
