The PCI interface and its importance for lightning-fast Mini PCs

21.10.2024

Choosing the right hardware components is crucial to optimally equip Mini PCs for their area of application. In particular, the interface via which components such as graphics cards, SSDs and network cards communicate plays a central role. One of the most important technologies in this area is the PCI or PCIe interface. We explain what PCIe is, why it is so important for modern mini PCs and where developments are currently heading.

What is PCI and PCIe?

The PCI interface (Peripheral Component Interconnect) was developed in the 1990s as a standard for connecting various expansion cards to a computer system. It enabled efficient communication between hardware components. However, as technological development progressed, the original PCI interface became a bottleneck for modern, high-performance devices.

This is where the Express version comes into play. PCIe (Peripheral Component Interconnect Express) is a further development of the previous technology, which offers much higher data transfer rates and better scalability. While PCI once worked with parallel data buses, PCIe relies on serial data transmission and offers several "lanes" that can be used in parallel. This leads to a drastic improvement in the speed and efficiency of data transmission.

Of course, you will also find one or two PCIe interfaces in our spo-comm product catalog. In addition to this port, our NOVA R680E offers some other interesting features!

Advantages of the interface for mini PCs

Higher data transfer rates
Mini PCs benefit from the high bandwidth of the PCIe interface. Whether connecting a graphics card or an NVMe SSD for lightning-fast data storage, this connection is now the standard for fast, stable connections. The latest version, PCIe 5.0, enables data rates of up to 32 GT/s (gigatransfers per second) per lane, giving Mini PCs unprecedented performance.

Outlook: It will be even more powerful with the upcoming PCIe 6.0 version, which is already within reach and promises transfer rates of up to 64 GT/s.
Flexibility and scalability
The interface has a modular structure. This means that there are different configurations, such as x1, x4, x8 or x16, which support different numbers of data channels. Mini PCs, which are usually designed to be compact, can thus be flexibly adapted to different requirements without having to compromise on performance.

Compatibility and future-proofing
Another advantage of PCIe technology is its backwards compatibility. This means that older devices with this interface can also be operated on newer PCIe slots. This makes the interface a future-proof solution that is ideal for mini PCs, as these are often in use for many years.

The next generation of data transmission

The next stage in the evolution of the PCIe interface is imminent with PCIe 6.0. This new version not only brings twice the data transfer rates of PCIe 5.0, but also more efficient error correction methods and even lower latency. For Mini PC users who need maximum performance in the smallest possible space, this is an absolute game changer. The newer version will make it possible to transfer even more data in less time, which is a clear advantage especially in data-intensive applications such as 3D graphics processing, machine learning and high-performance computing.
