Screen size

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.

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).

Max. RAM

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.

RAM type

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 Outperforms outdated DDR2 in terms of speed and power efficiency. However, it is also outdated against the background of the fourth version and new items - DDR5.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

RAM speed

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 and more.

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.

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.

Drive capacity

The capacity of the drive installed in the laptop. If there are several separate drives (for example, HDD + SSD, see "Drive type") — this item indicates the volume of the most capacious drive (in our example — HDD).

A larger drive allows you to store more data, but it also comes at a higher cost. At the same time, it is worth remembering that the price also depends on the type of media: for example, SSDs are much more expensive than hard drives of the same volume. So it is best to directly compare drives of the same type with each other. As for specific volumes, the most modest figures are typical for configurations with pure solid-state memory — SSD of one type or another or eMMC (see "Drive type"): among them you can find solutions for 240 – 360 GB and even 128 GB or less . Hard drive capacity actually starts at 480 – 512 GB ; 1TB storage capacity is average, and the most capacious modern laptops are equipped with storage of 2TB or even more.

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.
