Comparison HP 260 G9 DM 9M9K2AT vs HP Pro Mini 260 G9 883X8EA

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 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.

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.

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.

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.

The number of internal bays in the computer for components of the form factor 2.5 ". This form factor is popular, in particular, among SSD drives, as well as compact ("laptop") hard drives.

Paying attention to the number of internal 2.5" bays makes sense, first of all, if you purchase a configuration without drives or plan to upgrade your PC in the future. It is worth noting that it is recommended to install drives not in a row, but through one slot — for cooling efficiency; so that ideally the number of slots should be twice the number of devices installed.

Number of USB-C 5Gbps ports (previously labeled as USB-C 3.2 gen1 and USB-C 3.0) provided on the front panel of the PC; accordingly, the number of devices with such plugs that can be simultaneously connected to the front panel without using hubs.

USB-C was created as an improvement over the classic USB plug: it is noticeably smaller and has a reversible design, allowing the plug to be connected either way. And version 3.2 gen1 allows for data transfer speeds up to 4.8 Gbps; in fact, it is the most modest version of USB connectivity used in modern USB-C ports, but even such specifications are more than sufficient for most external devices with this type of connector.

It is worth noting separately that USB-C ports can also be provided on the rear side of the case. However, the front panel is closer to the user, and connectors on it are ideally suited for peripherals that need to be frequently connected and disconnected, such as flash drives.

The number of USB-C 10Gbps ports (previously labeled as USB-C 3.2 gen2 and USB-C 3.1) provided on the front panel of the PC; accordingly, the number of devices with such connectors that can be simultaneously connected to the front panel without using splitters.

USB-C was created as an improvement over the classic USB connector: it is noticeably smaller and has a reversible design, allowing the plug to be connected either way. Version 3.2 gen2 is an enhancement over 3.2 gen1, which achieves speeds of up to 10 Gbps and power delivery up to 100W (due to the USB Power Delivery feature). These capabilities are sufficient even for the most demanding modern devices with USB-C connections; however, peripherals with USB-C 3.2 gen1 can also be connected to ports of this type.

It is worth noting that USB-C ports can also be provided on the back of the case. However, the front panel is closer to the user, and the connectors on it are ideally suited for peripherals that need to be frequently connected and disconnected, such as flash drives.
