Screen size
Diagonal of the screen installed in a monoblock (see "Type").
In general, the larger the diagonal, the more advanced both the screen and the computer as a whole are considered. The large display size is convenient for games, movies, and some special tasks like layout of large printed materials; in addition, a higher resolution can be provided for such a screen, and more space is available inside the case for advanced components. On the other hand, a larger monoblock will cost much more than a relatively small one, even if the other characteristics of such models are completely the same. In addition, the power of the hardware is not directly related to the size of the screen — high-end monoblocks can be quite small.
As for specific numbers, a
diagonal of 20" or less is considered very limited nowadays,
monoblocks of 21.5" are small,
a 24" screen is medium, and values of
27" and
32" indicate large sizes.
Resolution
Resolution of the screen installed in the monoblock (see "Type").
The higher the resolution, the clearer and more detailed image the screen can produce, but the more expensive it is. In addition, high resolutions require corresponding powerful graphics, which further affects the price of the entire computer. The minimum indicator for modern monoblocks is actually 1366x768 — this resolution allows, in particular, to play HD 720p video in proper quality. However, nowadays, the more advanced format is most widely used —
Full HD, providing a resolution of 1920x1080. And in high-end monoblocks with a large diagonal and powerful graphics, there are also more solid resolutions —
Quad HD(2560x1440, 3440x1440),
Ultra HD 4K(3840x2160, 4096x2304) and even
5K(5120x2880) standards.
Model
The specific model of the processor installed in the PC, or rather, its index within its series (see "Processor"). The full model name consists of the series name and this index — for example, Intel Core i3 3220; knowing this name, you can find detailed information about the processor (characteristics, reviews, etc.) and determine how suitable it is for your purposes.
Speed
Clock speed of the CPU installed in the PC.
In theory, higher clock speeds have a positive effect on performance because they allow the CPU to perform more operations per unit of time. However, this indicator is rather weakly related to real productivity. The fact is that the actual capabilities of the CPU strongly depend on a number of other factors - the overall architecture, cache size, number of cores, support for special instructions, etc. As a result, you can compare by this indicator only chips from the same or similar series (see “CPU”), and ideally, also from the same generation. And that's pretty approximate.
TurboBoost / TurboCore
Processor clock speed when running in TurboBoost or TurboCore mode.
Turbo Boost technology is used in Intel processors, Turbo Core — AMD. The essence of this technology is the same both there and there: if some of the cores work under high load, and some are idle, then some tasks are transferred from more loaded cores to less loaded ones, which improves performance. This usually increases the clock frequency of the processor; this value is indicated in this paragraph. See above for more information on clock speed in general.
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.
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.
