Comparative test of all-in-one computers with a diagonal of 24". When you want elegance, space and a minimum of cables

Posted by


All-in-one computers are elegant computer solutions, whether at home or in the office. You have a much larger screen than a laptop, and you can do without a lot of cables and a computer case.

If you want a desktop computer that doesn’t take up more space on your desk than a regular monitor, an all-in-one PC is the ideal solution. With few exceptions, these computers are also very quiet, economical and, unlike laptops, offer a large screen located at a height ideal for comfortable work. Like a laptop, all you need to do is unpack your all-in-one computer and start using it.

In our test, the computers (except Umax) were also equipped with a keyboard and mouse, so you won’t have to buy anything. At the same time, there are a number of models on the market in different price categories and with different sizes of diagonals, you just have to choose. The biggest application of finding all-in-one computers in offices, offices and children’s rooms, but it will also serve well as home computers for multiple users.

Save space

They lack a computer case and all the electronics had to fit in the part behind the monitor, so you get rid of both the case and some cables. If you replace the wired keyboard and mouse with wireless and connect to Wi-Fi for the Internet, only one cable will run to your computer, the power cable.

Compared to laptops, all-in-one computers do not have a battery and you will also lose mobility, on the other hand, this can be an advantage in a family with children, because it does not harm the computer. You must also take into account that all-in-one computer manufacturers do not upgrade as fast as laptops, so modern processors arrive with some delay. Also, in the pursuit of thinner and quieter design, all-in-one computers no longer have desktop processors, but more often laptops.

Alphabetical list of tested models

  • Acer Aspire C24-1650
  • Asus V241EAK-BA056W
  • HP 24-cb0007nc
  • Lenovo IdeaCentre 3 24ALC6
  • Umax U-One 24GR Plus

You must be aware that it is impossible to replace the processor in such a computer, but as you can see in our test – memory, SSD or Wi-Fi modules can be upgraded if necessary. Even so, all-in-one computers take over the illness of laptops here – in the event of an unprofitable computer failure, you will also lose your monitor. In addition, you will no longer replace the monitor, you can connect another, secondary one.

All-in-ones are usually so quiet today that you won’t know about them. But there are exceptions

First of all, when choosing an all-in-one computer, you should focus on the diagonal of the screen. In e-shops you will find a range from the smallest 15.6 “models, which are already on the verge of extinction, to 32” models designed for the most demanding users. The best-selling diagonal is 23.8 “and there is also the largest selection among these computers. Another popular diagonal is 21.5”, but here the selection is becoming more and more limited. On the contrary, 27 “all-in-one computers are becoming more and more popular, the price of which has already fallen below twenty thousand, but unfortunately they are currently quite ill with stock availability.

You will also find higher resolution than Full HD, from QHD to 5K. However, the richer offer of 23.8 “models, which are also the most cost-effective, is the reason why we focused on them in our test. In our test you will meet only models with a classic matte IPS display, but there are also those on the market that they boast touch controls, but there are also fewer and fewer.

An important processor

In our test you can see two categories of processors: cheap SoC present in the Umax computer and classic full-fledged notebook processors from either AMD or Intel. The third category can still be seen, namely desktop processors with reduced TDP, which is indicated by the letter T at the end of their designation. Cheap SoCs are Pentia and Celerons, formerly known as Atoms. The newest family in this category is the Intel Jasper Lake with 6W processors such as the Celeron N5100, Celeron N5105 or Pentium Silver N6000. However, Umax in our test was equipped with an older Celeron N4020 from the previous Intel Gemini Lake family.

Jasper Lake offers quite a sharp increase in performance and, for example, hardware support for the webcam (eg keying a different background), while Gemini Lake is still obsolete – you can see how slow it is from comparing performance with conventional notebook processors. With Umax, however, this is offset by the low cost of the whole computer.

Disassembling the Lenovo IdeaCentre 3 24ALC6 all-in-one computer is very difficult, but you get to a free memory slot and M.2 Wi-Fi and M.2 PCIe SSD

With the classic Intel notebook processors, you will meet three generations: the oldest Core 10 from the Ice Lake and Comet Lake families, the Core 11 from the newer Tiger Lake family, and the Core 12 from the Alder Lake family, such as the Intel Core i5- 1240P. Intel has to try, because the 11th generation Core i5, which was used by most computers in our test, successfully humiliates the Ryzen 5 5500U, which boasts two extra cores and parallel processing of up to 12 threads simultaneously.

But all-in-one computers equipped with older Ryzens 4000 are not a bad choice either. But which processor should you choose in the end? Ideally the latest, with the Core i5 or Ryzen 5 being the optimal and overwhelming majority for most users.

All-in-one computers are generally not very suitable for gaming, except for narrowly specialized models. In the category up to CZK 20,000, you will find only integrated graphics, with the exception of a few models with Nvidia GeForce MX330 graphics, which, however, is sufficient only for the most basic 3D gaming. For gaming, it is simply better to reach for a gaming laptop or a classic desktop computer. Or, in the case of an all-in-one computer, reach deep into your wallet for a model with at least the Nvidia RTX 3060 graphics.

Disk, memory and other components

As you can see in our test, all-in-one computers have finally abandoned platters and only use SSDs for the system, so you can count on fast application and file loading and lower noise. In addition, both laptops have fast M.2 PCIe SSDs. Therefore, if you still encounter an all-in-one computer equipped with only a classic disk, you should avoid such a configuration. It’s better to reach for a model with a weaker processor than to compromise system storage.
