Form factor
The form factor of a computer case characterizes, first of all, the internal volume. Main PC Form Factors:
—
Midi Tower. A representative of the tower family (tower cases) of medium size — about 45 cm in height with a width of 15-20 cm, with the number of external bays from 2 to 4. Most popular for middle-class home PCs.
—
Mini Tower. The most compact "vertical" case type, with a width of 15-20 cm, has a height of about 35 cm and (usually) less than 2 compartments with external access. Used mainly for office PCs that do not require high performance.
—
Full Tower. The tower case is one of the largest form factors for PCs today: 15-20 cm wide, 50-60 cm high, with up to 10 externally accessible bays. Most often in this form factor running advanced high performance PCs
—
Desktop. Enclosures designed for installation directly on the desktop. They often have the possibility of horizontal installation — in such a way that a monitor can be placed on top of the case — although there are also models that are installed strictly vertically. Anyway, "desktop" models are relatively small.
—
Cube Case. Cases having a cubic or close to it shape. They can have different sizes and are intended for different types of motherboards, this point in each case should be clar
...ified separately. Anyway, such cases have a rather original appearance, different from traditional "towers" and "desktops".Chipset
The model of the chipset used in the standard configuration of the PC.
A chipset can be described as a set of chips that provides the combined operation of the central processor, RAM, I / O devices, etc. It is this chipset that underlies any motherboard. Knowing the chipset model, you can find and evaluate its detailed characteristics; most users do not need such information, but for specialists it can be very useful.
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.
Geekbench 4
The result shown by the PC processor in the test (benchmark) Geekbench 4.
Geekbench 4 is a comprehensive cross-platform test that allows, among other things, to determine the efficiency of the processor in various modes. At the same time, according to the developers, the verification modes are as close as possible to various real tasks that the processor has to solve. The result is indicated in points: the more points — the more powerful the CPU, while the difference in numbers corresponds to the actual difference in performance ("twice the result — twice the power").
Note that the benchmark in Geekbench 4 is the Intel Core i7-6600U processor with a clock frequency of 2.6 GHz. Its power is estimated at 4000 points, and the performance of other tested CPUs is already compared with it.
Cinebench R15
The result shown by the PC processor in the test (benchmark) Cinebench R15.
Cinebench is a test designed to test the capabilities of the processor and graphics card. The creator of this benchmark, Maxon, is also known as the developer of the Cinema 4D 3D editor; this determined the features of testing. So, in addition to purely mathematical tasks, when using Cinebench R15, the processor is loaded with processing high-quality three-dimensional graphics. Another interesting feature is the extensive support for multithreading — the test allows you to fully check the power of chips that process up to 256 threads at a time.
Traditionally, for CPU benchmarks, the test results are indicated in points (more precisely, points — PTS). The more points scored by the CPU, the higher its performance.
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.
3DMark
The result shown by the PC graphics card in the 3DMark test (benchmark).
3DMark is a specialized test designed primarily to test the performance and stability of a graphics card in demanding games. The verification is carried out by running 3D videos created on various game engines using various technologies. The final result is evaluated both in terms of frame rate and in conditional points; in this paragraph, just the number of points is given. The higher it is, the more powerful and performant the graphics card is.
Note that 3DMark testing can be carried out for any type of graphics (see "Graphics card type"). At the same time (as of 2020) in integrated solutions, the final result rarely exceeds 1000 points; the most modest indicator for discrete adapters is about 1700 points; and in some high-end graphics cards, it can exceed 10,000 points.
Passmark G3D Mark
The result shown by the PC graphics card in the test (benchmark) Passmark G3D Mark.
Passmark G3D Mark is a comprehensive test to check the performance of a graphics card in various modes. Traditionally for such tests results are displayed in points, more points mean (proportionately) higher computing power. However, note that the graphics card is tested in different modes, and the final score is derived based on several results in specialized tests. Therefore, adapters with a similar overall result may differ slightly in actual performance in certain specific formats of operation. So if a PC is purchased for professional work with graphics, and high efficiency in some specialized tasks is critical, it will not hurt to clarify these nuances separately.
Note that with the help of Passmark G3D Mark, nowadays, all types of graphics adapters are tested (see "Graphics card type"). At the same time, for integrated solutions, a result of more than 1200 points is considered very good, and in discrete models this figure can vary from 2200 – 2300 points to 20,000 points or more.
2nd drive capacity
The capacity of the optional storage installed in the PC.
This parameter is relevant primarily for configurations with different types of media. So, in HDD + SSD and HDD + eMMC bundles, the hard drive is considered the main drive, and this paragraph indicates the capacity of the solid-state module. In SSD + eMMC configurations, eMMC is considered the second drive — less capacious and performing an auxiliary function. There are PC models with two hard drives, but in such cases, the drives usually have the same volume, and it does not matter for them which one is considered the main one.
If we talk about specific numbers, then the volume
up to 128 GB can be considered relatively small, and
128 GB or more is solid. For more information on volumes in general, see "Drive Capacity" above.
