True. However, I've always noticed that ARM has less Linux support than x86, and the main benefits ARM is known for are typically performance/watt, running cooler, and less legacy support.

Since this server seems to have pretty average performance/watt and cooling, I can't really see much advantage to ARM here, at least for typical server use cases.

Unless you're doing ARM development, but I feel like a Pi 4/5 is better for basic development.

The performance is not average when compared with other ARM-based cheap computers, because it is high in comparison with them. It is also not average when compared to cheap Intel/AMD computers, because compared to such computers it is low. It could be called average only when averaging cheap ARM-based computers with cheap x86-64 based computers.

This computer uses 8 Cortex-A720 cores (and 4 little cores with negligible performance), which have a performance similar to the older Intel E-cores, i.e. Gracemont or Crestmont from Alder Lake, Raptor Lake or Meteor Lake. They are much slower than the recent Intel E-cores, i.e. Skymont or Darkmont, from Arrow Lake or Panther Lake.

So the performance of the whole CPU is similar to the 8-core Intel N300 (Alder Lake N) or Intel N350 (Twin Lake), which are found in various mini-PCs that are cheaper than this ARM computer.

Even so, the performance of this ARM CPU is many times greater than that of a Raspberry Pi and greater than of any cheaper ARM CPU. For greater performance, you must buy a more expensive smartphone, or a Qualcomm or Apple laptop or mini-PC, or a very expensive development computer from NVIDIA.

Linux support for ARM is inferior for end users of desktop 3rd party software. Everything else is provided by the repos. I doubt this person runs Signal or Spotify on those servers.
