Comparison MSI Cubi 2 025BEU-B3865UXX vs MSI Cubi 009BEU-B3805UXX

The general type (specialization) of the processor installed in the PC.

— Desktop. Processors originally designed for full-sized desktop computers. The specific characteristics of such CPUs can vary quite widely; however, in general, they have higher processing power than mobile chips, as well as a wider range of additional features and special solutions to improve efficiency. And with the same actual performance, desktop solutions are much cheaper than mobile ones. The downside of these advantages is the relatively high energy consumption and heat dissipation. However, for full-sized PCs, these shortcomings are not critical, so almost all traditional desktop computers, as well as most all-in-ones (see "Type") are equipped with this particular type of processor; and for powerful gaming models, a desktop CPU is mandatory by definition. On the other hand, this category also includes rather economical and "cold" low-power chips, which are suitable for compact computers that do not require high performance, such as nettops and thin clients.

— Mobile. This term in this case refers to processors originally designed for laptops. Most of these CPUs use the same basic architecture as desktop models — x86. Their main differences are: on the one hand, reduced energy consumption, reduced clock frequencies and low heat generation, on the other hand, less computing power in general. However the actu...al characteristics of such processors may vary from model to model, some laptop solutions are not inferior to fairly advanced desktop ones; however, with similar capabilities, a laptop processor will cost significantly more. Thus, this type of CPU is mainly used in nettops and individual models of monoblocks (see "Type"), where it is difficult to use powerful cooling systems.
A rarer variety of mobile processors used in modern PCs are chips based on the basic ARM architecture. Such processors have even lower heat dissipation and power, and are also often implemented in the System-On-Chip format, when the CPU itself, RAM, wired and wireless connection controllers, and other components are combined in one chip. ARM solutions can be found in Android touchscreen all-in-ones (which are effectively "desktop tablets"), as well as in individual thin clients.

The main manufacturers of processors nowadays are Intel and AMD, also in 2020, Apple introduced its M1 series CPUs (with further development as M1 Max and M1 Ultra), later showing the next generation M2(M2 Pro, M2 Max, M2 Ultra). The list of current Intel series includes Atom, Celeron, Pentium, Core i3, Core i5, Core i7, Core i9 and Xeon. For AMD, in turn, this list looks like this: AMD Athlon, AMD FX, Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9 and Ryzen Threadripper.

In general, each series includes processors of different generations, similar in general level and positioning. Here is a more detailed description of each of the options described above:

— Atom. Processors originally designed for mobile devices. Accordingly, they are distinguished by compactness, high energy efficiency and low heat dissipation, but they “do not shine” with performance. Perfect for microcomputers (see "Type"), among the more "large-format" systems are extremely rare — mostly in the most modest configurations.

— Celeron. Low-cost-level processors, the most simple and inexpensive consumer-level desktop chips from Intel, with the appropriate characteristics.

— Pentium. A family of low-cost desktop processors from Intel that is slightly more advanced than Celeron, but inferior to models from the Core i* series.

— Core i3. The simplest and most inexpensive series of desktop Core chips from Intel includes chips of the low-cost and inexpensive middle class, which, nevertheless, surpass Celerons and Pentiums in terms of performance.

— Core i5. Medium-level family among Intel Core processors; and in general, the chips of this series can be attributed to the average level by the standards of desktop systems.

— Core i7. A series of high-performance processors that has long been the top among Core chips; only in 2017 did it lose this position to the i9 family. However, the presence of an i7 processor still means a fairly powerful and advanced configuration; in particular, such CPUs are found in premium-level monoblocks, and are also quite popular in gaming systems.

— Core i9. The top series among Core processors, the most powerful among general purpose Intel desktop chips. In particular, the number of cores even in the most modest models is at least 6. Such chips are used mainly in gaming PCs.

— Xeon. High-end Intel processors, the capabilities of which go beyond the standard desktop chips. Designed for specialized applications, among PCs they are found mainly in powerful workstations.

— AMD FX. A family of processors from AMD, positioned as high-performance and at the same time inexpensive solutions, including for gaming systems. Interestingly, some models come standard with liquid cooling.

— Ryzen 3. AMD Ryzen chips (all series) are promoted as high-end solutions for gamers, developers, graphic designers and video editors. It was among these chips that AMD pioneered the Zen microarchitecture, which introduced simultaneous multithreading, which made it possible to significantly increase the number of operations per clock at the same clock frequency. And Ryzen 3 is the most inexpensive and modest family among the "ryzens" in terms of characteristics. Such processors are produced using the same technologies as the older series, however, half of the computing cores are deactivated in Ryzen 3. Nevertheless, this line includes quite performant models, designed, among other things, for gaming configurations and workstations.

— Ryzen 5. A family related to the middle level among Ryzen processors. The second series on this architecture, released in April 2017 as a more affordable alternative to Ryzen 7 chips. Ryzen 5 chips have slightly more modest performance characteristics (in particular, lower clock speeds and, in some models, L3 cache size). Otherwise, they are completely similar to the "sevens" and are also positioned as high-performance chips for gaming and workstations.

— Ryzen 7. Historically the first series of AMD processors based on the Zen microarchitecture (for more details, see "Ryzen 3" above). One of the older families among the "ryzens", in terms of performance it is second only to the Threadripper line; many PCs based on these chips are gaming.

— Ryzen Threadripper. Specialized Hi-End processors designed for maximum performance. They are mainly installed in gaming systems and workstations.

— Apple M1. A series of processors from Apple introduced in November 2020. They belong to mobile solutions (see "Type" above), are performed according to the system-on-chip scheme: a single module combines a CPU, a graphics adapter, RAM (in the first models — 8 or 16 GB), an NVMe solid-state drive and some other components (specifically Thunderbolt 4 controllers). Accordingly, among PCs, the main scope of such chips are compact nettops. As for the characteristics, in the initial configurations, the M1 processors are equipped with 8 cores — 4 performant and 4 economical; the latter, according to the creators, consume 10 times less energy than the former. This, combined with the 5nm process technology, has made it possible to achieve very high energy efficiency and at the same time performance.

— Apple M1 Max. An uncompromisingly powerful SoC with a focus on maximizing Apple desktop productivity for complex tasks. The Apple M1 Max line was introduced in the fall of 2021, it debuted on board Mac Studio computers.

Apple M1 Max consists of 10 cores: 8 of them are productive, and 2 more are energy efficient. The maximum amount of built-in combined memory reaches 64 GB, the “ceiling” of its bandwidth is 400 GB / s. The graphics performance of the Max version of the M1 single-chip system is about twice that of the Apple M1 Pro. The chip contains over 57 billion transistors. An additional accelerator for the professional ProRes video codec has also been introduced into its design, which allows you to easily play multiple streams of high-quality ProRes video in 4K and 8K frame resolutions.

— Apple M1 Ultra. Formally, the M1 Ultra chip consists of two Apple M1 Max processors on a single UltraFusion substrate, which allows information transfer at speeds up to 2.5 Tbps. In the language of "dry" numbers, this bundle consists of 20 ARM computing cores (16 high-performance and 4 energy efficient), a 64-core graphics subsystem and a 32-core neural computing unit. The system-on-chip supports up to 128 GB of combined memory. About 114 billion transistors are packed into the processor package. The main purpose of the Apple M1 Ultra is to confidently work with complex resource-intensive applications in the manner of processing 8K video or 3D rendering. In life, the processor can be found on board Mac Studio desktop computers.

In addition to the series described above, in modern PCs you can find the following processors:

— AMD Fusion A4.... The entire Fusion processor family was originally created as integrated graphics devices, combining a central processing unit and a graphics card in one chip; such chips are called APU — Accelerated Processing Unit. Series with the index "A" are equipped with the most powerful integrated graphics in the family, which in some cases can compete on equal terms with inexpensive discrete video cards. The higher the number in the series index, the more advanced it is; A4 is the most modest series among Fusion A.

— AMD Fusion A6. A series of processors from the Fusion A line, relatively modest, but somewhat more advanced than the A4. For common features of all Fusion A, see "AMD Fusion A4" above.

— AMD Fusion A8. A rather advanced series of Fusion A processors, the middle option between the relatively modest A4 and A6 and the high-end A10 and A12. For common features of all Fusion A, see "AMD Fusion A4" above.

— AMD Fusion A9. Another advanced series from the Fusion A family, slightly inferior only to the A10 and A12 series. For common features of all Fusion A, see "AMD Fusion A4" above.

— AMD Fusion A10. One of the top series in the Fusion A line. See "AMD Fusion A4" above for general features of this line.

— AMD Fusion A12. The top series in the APU Fusion A line, introduced in 2015; positioned as professional-level processors with advanced (even by APU standards) graphics capabilities. For general features of the Fusion A range, see "AMD Fusion A4" above.

— AMD E-series. This series of processors belongs to the APU, like the Fusion A described above, however, it is fundamentally different in specialization: the main scope of the E-Series are compact devices, in the case of PCs, mostly nettops (see "Type"). Accordingly, these processors have compactness, low heat dissipation and power consumption, but their computing power is also low.

— Athlon X4. A series of low-cost consumer-level processors, originally released in 2015 as relatively inexpensive and at the same time relatively performant solutions for the FM + socket.

— AMD G. A family of ultra-compact and energy-efficient processors from AMD, made on the principle of "system on a chip" (SoC). Unlike many similar chips, it uses the x86 architecture, not ARM. Positioned as a solution for devices with an emphasis on graphics, in particular, gaming. However, we are not talking about gaming PCs: like most processors of a similar "weight category", AMD G is found mainly in thin clients (see "Type").

— VIA. Processors from the company of the same name, mainly related to energy-efficient "mobile" solutions — in particular, many VIA models are directly compared with Intel Atom. However, despite the modest performance, such CPUs are found even among desktop systems; and in the future, the company plans to create full-fledged desktop chips, competing with AMD and Intel.

— ARM Cortex-A. A group of processors from ARM, the creator of the microarchitecture of the same name and the largest manufacturer of chips based on it. A feature of this microarchitecture compared to the classic x86 is the so-called reduced instruction set (RISC): The processor operates with a simplified instruction set. This somewhat limits the functionality, but allows you to create more compact, "cold" and at the same time performant chips. For a number of reasons, the ARM architecture is mainly used in "mobile" processors designed for smartphones, tablets, etc. This is also true for the ARM Cortex-A series; in PCs, such CPUs are rarely installed, and usually we are talking about a compact, modest device like a “thin client” (see “Type”).

— Nvidia Tegra. Initially, these processors were created for portable devices, but recently they have also been installed in PCs, mainly in monoblocks. They are "system-on-chip" devices that do not use the "desktop" x86 architecture, but the "mobile" ARM architecture, which requires the use of appropriate operating systems; the most commonly used is Android (see "Preinstalled OS").

— Armada. Another type of ARM architecture processors, positioned as high-performance solutions for cloud computing and home servers, including NAS. It is found in single models of "thin clients" (see "Type").

— Tera. A specialized family of processors designed specifically for "thin clients" (see "Type") and fundamentally different from classic CPUs (both full-size and compact). Tera-based systems are usually full-fledged "zero clients" (zero client), absolutely not capable of autonomous operation. In other words, these are devices designed to create a "virtual desktop": the user works with the interface and terminal equipment (monitor, keyboard, mouse, etc.), but all operations take place on the server. This allows you to provide increased security when working with sensitive data. But in more traditional PCs, Tera processors are practically inapplicable.

Of the outdated series of processors that can still be found in use (but not for sale), we can mention the Sempron, Phenom II and Athlon II from AMD, as well as the Core 2 Quad and Core 2 Duo from Intel.

Note that on the market there are configurations that are not equipped with a processor — in the expectation that the user can pick it up on his own; however, this is a rather rare option.

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.

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.

The type of RAM used in the computer. This indicator describes both the general level of "RAM" and the possibilities for replacing and upgrading it: different types of RAM are not compatible with each other.

Here are the types of memory that are relevant for modern PCs:

— DDR3. The third generation of RAM with the so-called double data transfer. Some time ago, this standard was the most popular in computer technology, but now it is increasingly losing ground to newer and more advanced standards, primarily DDR4. In compact computers, there is a "mobile", energy-saving version of this memory standard — LPDDR3.

— 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 improves performance. These modules are compatible with classic DDR3 slots.

— DDR4. Further, after DDR3, the development of the DDR standard, released in 2014. It features both increased performance and increased volumes — the capacity of one bar can be from 2 to 128 GB. Thus, the maximum amount of RAM in most PCs is limited more by the capabilities of the motherboard than by the characteristics of existing brackets. DDR4 is very popular in modern computer technology, including desktop PCs.

The clock speed of the RAM that comes with the PC. This is one of the parameters that determine the capabilities of RAM: with the same amount and type of memory (see above), a higher clock frequency will mean faster performance. However such details are rarely required by an ordinary user, but they are important for enthusiasts and professionals.

Also note that this indicator can be used to determine the possibilities for upgrading the system: the motherboard will be able to work normally with brackets that have the same or lower clock frequency, but compatibility with faster memory should be specified separately.

The main manufacturers of video cards nowadays are 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, GeForce RTX 3090 Ti), GeForce RTX 4060 , GeForce RTX 4060 Ti, GeForce RTX 4070, GeForce RTX 4070 SUPER, GeForce RTX 4070 Ti, GeForce RTX 4070 Ti SUPER, Ge Force RTX 4080, GeForce RTX 4080 SUPER, GeForce RTX 4090 and separate 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.

The type of storage device that is installed in the computer.

Note that many PCs allow you to add a complete drive or even completely replace it, but it is more convenient to buy a suitable configuration initially and not bother with re-equipment. In terms of types, traditional hard disk drives ( HDD) are increasingly losing ground to SSD solid-state modules nowadays. In addition, HDD + SSD combinations are quite popular (including those using advanced Intel Optane and Fusion Drive technologies). But solutions such as SSHD and eMMC have practically fallen into disuse. Let's take a closer look at these options:

— HDD. Classic hard disk. The key advantage of such drives is their low cost per unit of volume — this allows you to create capacious and at the same time inexpensive storage. On the other hand, HDDs are noticeably inferior to SSDs in terms of speed, and they also do not tolerate shocks and shocks. Thus, this type of media is less and less used in its pure form — it is much more common to find a combination of a hard drive with an SSD module (see below).

— SSD. Solid state drives based on flash memory. With the same volume, an SSD is much more expensive than an HDD, but this is justified by a number of advantages. First, such drives are much faster than hard drives; specif...ic performance may be different (depending on the type of memory, connection interface, etc.), however, even inexpensive SSDs outperform advanced HDDs in this indicator. Secondly, solid-state memory has no moving parts, which offers several advantages at once: lightness, compactness, shock insensitivity and low power consumption. And the cost of such memory is constantly decreasing as technology advances. So more and more modern PCs are equipped with just such drives, and these can be configurations of any level — from low-cost to top ones.

— HDD+SSD. The presence in one system of two drives at once — HDD and SSD. Each of these varieties is described in more detail above; and their combination in one system allows you to combine the advantages and partially compensate for the shortcomings. For example, an SSD (which usually has a fairly small capacity) can store system files and other data for which speed of access is important (for example, work applications); and HDD is well suited for large volumes of information that do not require particularly high speed (a typical case is video files and other multimedia content). In addition, the solid-state module can be used not as a separate storage, but as an intermediate cache to speed up the hard drive; however, this usually requires special software settings (whereas the "two separate drives" mode is most often available by default).
We also emphasize that in this case we are talking about “ordinary” SSD modules that do not belong to the Optane and Fusion Drive series; the features of these series are detailed below.

HDD + Optane. Combination of a traditional hard drive with an Intel Optane series SSD. For more information about the general features of this combination, see "HDD + SSD" above. Here, we note that “optains” differ from other SSD drives in a special three-dimensional structure of memory cells (3D Xpoint technology). This allows you to access data at the level of individual cells and do without some additional operations, which speeds up the speed and reduces latency, and also has a positive effect on memory life. The second difference is that Optane is usually used not as a separate drive, but as an auxiliary buffer (cache) for the main hard drive, designed to increase speed. Both drives are perceived by the system as a single device. The disadvantage of this type of SSD is traditional — a rather high cost; it is also worth noting that its superiority is most noticeable at relatively low loads (although it does not disappear completely with increasing load).

— HDD + Fusion Drive. A kind of HDD + SSD bundle (see above), used exclusively in Apple computers and optimized for the proprietary macOS operating system. However, it would be more correct to compare this option with the “HDD + Optane” combination (also described above): for example, both drives are perceived by the system as a single unit, and the Fusion Drive module is also used as a high-speed cache for the hard drive. However, there are also significant differences. Firstly, Fusion Drive has significant volumes and is used not only as a service buffer, but also as part of a full-fledged drive — for permanent data storage. Secondly, the total volume of the entire bundle approximately corresponds to the sum of the volumes of both drives (minus a couple of "service" gigabytes). This type of drive is expensive, but the efficiency and convenience are well worth the price.

— SSHD. The so-called hybrid drive: a device that combines a hard drive and a small SSD cache in one case. Some time ago, this solution was quite popular, but now it is almost never found, having been supplanted by a more practical option — various types of HDD + SSD.

— eMMC. A type of solid-state memory originally developed for portable gadgets such as smartphones and tablets. It differs from SSD, on the one hand, in lower cost and low power consumption, on the other hand, in relatively low speed and reliability. Because of this, this type of drive is used extremely rarely — in particular, in single models of microcomputers and thin clients (see "Type").

— HDD + eMMC. Combination of hard disk drive (HDD) and eMMC solid state module. These types of drives are described in detail above; here we note that this option is extremely rare, and in rather specific devices — monoblocks (see "Type") with a transformer function, where the screen is a removable tablet that can be used autonomously. In such a tablet, an eMMC module is usually installed, and a hard drive is placed in the stationary part. However, another option is also possible — a bundle similar to HDD + SSD (see above), where eMMC is used to reduce cost and/or power consumption.

— SSD + eMMC. Another combination of the two types of drives described above. It was used in single monoblocks and nettops — mainly to reduce the cost; Today, this variant is almost non-existent.

The number of full-size USB 3.2 gen1 connectors(previously labeled USB 3.1 gen1 and USB 3.0) provided on the front panel of the PC.

USB is the most popular modern interface for connecting peripherals. And the number of connectors is, accordingly, the number of devices that can be simultaneously connected to the front panel without the use of splitters. As for version 3.2 gen1, it has speeds up to 4.8 Gbps). USB 3.2 gen1 connectors are also compatible with USB 2.0 peripherals. Thus, 2 or more such connectors are often provided on the front panel at once.

Separately, it is worth noting that similar ports are most often available on the back of the case. However, the front panel is closer to the user, the connectors on it are optimally suited for peripherals that need to be connected and disconnected frequently, such as flash drives.
