Passmark CPU Mark
The result shown by the PC processor in the test (benchmark) Passmark CPU Mark.
Passmark CPU Mark is a comprehensive test that allows you to evaluate CPU performance in various modes and with a different number of processed threads. The results are displayed in points; the more points, the higher the overall performance of the processor. For comparison: as of 2020, in low-cost solutions, the results are measured in hundreds of points, in mid-range models they range from 800 – 900 to more than 6,000 points, and individual top-end chips are capable of showing 40,000 points or more.
RAM
The amount of random access memory (RAM, or RAM) that came with your computer.
The overall performance of the PC directly depends on this parameter: ceteris paribus, more RAM speeds up work, allows you to cope with more resource-intensive tasks, and facilitates the simultaneous execution of numerous processes. As for specific numbers, the minimum volume required for the stable operation of a general-purpose PC nowadays is
4 GB. Smaller amounts are enough for microcomputers and thin clients, and at least
8 GB is installed in gaming systems, on the contrary.
16 GB and even more so
32 GB are already very solid volumes, and in the most powerful and performant systems there are values \u200b\u200bof
64 GB and even more. Also on the market you can find configurations
without RAM at all — for such a device, the user can choose the amount of memory at his discretion; for a number of reasons, this configuration is especially popular in nettops.
Note that many modern PCs allow for an increase in the amount of RAM, so it does not always make sense to purchase an expensive device with a large amount of "RAM" — sometimes it is more reasonable to start with a simpler model and expand it if necessary. The possibility of upgrading in such cases should be clarified separately.
Number of slots
The number of slots for RAM modules provided on the PC motherboard. In this case, we are talking about slots for removable strips; for a PC with
built-in memory, this parameter is irrelevant.
The slots available on the "motherboard" can be occupied all, partially or not occupied at all (in models
without RAM). Anyway, you should pay attention to their number if the initially installed amount of RAM does not suit you (or ceases to suit you over time), and you plan to upgrade the system. The smallest amount found in a PC with removable memory is
1 slot ; if it is busy, you will only have to change the bar when upgrading. More connectors for RAM are always paired, this is due to a number of technical nuances; most often this number is
2 or
4, but it can be large — up to 16 in powerful workstations.
Note that when planning an upgrade, you need to take into account not only the number of slots and type of memory (see above), but also the characteristics of the motherboard. All modern "motherboards" have restrictions on the maximum amount of RAM; as a result, for example, the presence of two DDR4 slots does not mean that two strips of maximum capacity can be installed in the system at once, 128 GB each.
Max. memory support
The maximum amount of RAM that can be installed on a computer. 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 PC is bought with the expectation of upgrading RAM and the amount of actually installed memory in it is noticeably less than the maximum available
So the amount of maximum installed memory depends on the number of slots in the PC and can be from
16 GB(a modest PC) to
64 GB and above. The most popular on the market are
PCs with a maximum installed 32 GB of memory.
Graphics card model

AMD,
NVIDIA and Intel, and each has its own specifics. NVIDIA produces primarily discrete solutions; Among the most common are
the GeForce MX1xx,
GeForce MX3xx,
GeForce GTX 10xx series (in particular
GTX 1050,
GTX 1050 Ti and
GTX 1060),
GeForce GTX 16xx,
GeForce RTX 20xx,
GeForce RTX 30xx(
GeForce RTX 3060,
GeForce RTX 3060 Ti,
GeForce RTX 3070,
GeForce RTX 3070 Ti,
GeForce RTX 3080,
GeForce RTX 3080 Ti, GeForce RTX 3090,

Quadro series. AMD offers both discrete and integrated graphics - including the popular
Radeon RX 500,
Radeon RX 5000,
Radeon RX 6000,
Radeon RX 7000 and
AMD Radeon Pro series. And Intel deals exclusively with modules integrated into processors of its own production - these can be HD Graphics, UHD Graphics and Iris.
Note that many configurations with discrete graphics also have an integrated graphics module; in such cases, the name of the discrete video card is indicated as more advanced.
Graphics memory
The amount of native memory provided by the discrete graphics card (see "Graphics card type").
The larger this volume, the more powerful and advanced the video adapter is, the better it handles with complex tasks and, accordingly, the more expensive it is. Nowadays,
2 GB and
3 GB are considered quite modest,
4 GB are not bad,
6 GB and
8 GB are very solid, and more than 8 GB means that we have a specialized PC built for maximum graphics performance.
Memory type
The type of graphics memory used by the discrete graphics card (see "Video Card Type").
In most of these adapters, GDDR graphics memory is installed — a kind of regular DDR "RAM", optimized for use with graphics tasks. This memory is available on the market in several versions; in addition, there are other varieties. Here is a more detailed description of the different options:
— GDDR3. At one time — a fairly common type of graphic memory; today, however, it is considered obsolete and is not used in new PCs.
— GDDR5. The most popular (for 2020) type of GDDR graphic memory. At a reasonable cost, it provides good performance, due to which it is found in computers of different price categories.
— GDDR5X. Modification of the above-mentioned GDDR5, characterized by a 2-fold increased throughput. Accordingly, the performance of such memory (with the same volumes) is noticeably higher; on the other hand, such modules are expensive.
— GDDR6. The newest of the GDDR standards for 2020 — the first video cards based on this type of memory were introduced in 2018. It differs from its immediate predecessor — GDDR5X — in both increased bandwidth and lower operating voltage, which provides both increased efficiency and reduced power consumption. It is also worth noting that GDDR6 was developed with specific applications in mind, such as VR or work with resolutions above 4K UHD.
— HBM2. The original HBM is a type of RAM d...esigned to maximize the speed of data exchange; HBM2 is the second version of this technology, in which the bandwidth compared to the original HBM has been doubled. Such a memory is fundamentally different from DDR in terms of device — in particular, the memory cells in it are placed in layers and allow simultaneous access. Thanks to this, HBM is several times faster than the fastest versions of GDDR, which makes this technology perfect for high workloads such as processing UltraHD graphics and virtual reality. At the same time, the clock frequency of such modules is low and, accordingly, power consumption and heat dissipation are small. The disadvantage of this option is traditional — the high price.
— DDR3. Memory that does not have a specialization for graphics — in other words, the same DDR3 that is used in RAM sticks (see "Memory Type" above). In the case of video cards, such solutions are completely obsolete and are almost never used nowadays.
VR
Support for virtual reality technologies by a PC graphics card, in other words, the ability to use VR glasses and helmets with a computer. Such equipment gives a powerful effect of immersion in what is happening — the image in front of the eyes changes when the head moves, as if the user is looking at it live. However, processing such graphics requires high performance, as well as support for some special technologies. So if you intend to use VR, you should choose a system for which this feature is directly stated.
VR support is found primarily in professional gaming PCs, but it can also be useful for developers involved in VR applications.
Drive capacity
The volume of the main drive supplied with the PC. For models with combined storages (for example, HDD+SSD, see "Drive type"), in this case, the main one is considered to be a more capacious hard drive; and if there are two HDDs in the kit, then they usually have the same capacity.
From a purely practical point of view, the more data the drive holds, the better. So the choice for this indicator rests mainly on the price: a larger capacity inevitably means a higher cost. In addition, we recall that SSD-modules in terms of gigabytes of capacity are much more expensive than hard drives; so you can only compare carriers of the same type by the combination of volume and cost.
As for the specific capacity, a volume of
250 GB or less in modern PCs can be found mainly among SSDs. Hard drives of this size are almost never found, for them a capacity
of 250 to 500 GB is still considered quite modest.
501 – 750 GB is a pretty good value for an SSD, and among them it is also mainly used.
751 GB — 1 TB is an impressive figure for an SSD and an average for hard drives,
1.5 – 2 TB is a very solid capacity even for an HDD. And a very high capacity —
more than 2 TB — paradoxically, is found even among pure SSDs: such drives are installed in high-end workstations, where speed
...is no less important than capacity.
