An ARM based server almost sounds like an oxymoron.

Why so? Even cloud giants are moving in that direction[1]. When next generation Mac Mini with Apple Silicon comes out, data centers using that would be running Apple Server packages on that. In fact I've been running my production applications on ARM servers for ~a year and it has resulted in greater capital efficiency. I've been using Pi 2 with USB storage as a publicly hosted git server for over 5 years used by multiple users. [1]https://aws.amazon.com/ec2/graviton/ https://aws.amazon.com/ec2/graviton/

Heh, the fastest HPC cluster on the top 500 list is arm. Amusingly #2, #3, and #4 aren't x86-64 either. Number 5 is, but mainly because the xeons are handling I/O for the real heavy lifting on the matrix-2000 accelerators. The first pure x86-64 cluster is #8. So the performance story is changing quickly, and arm is just getting started.

  Japan Captures TOP500 Crown with Arm-Powered Supercomputer https://top500.org/news/japan-captures-top500-crown-arm-powered-supercomputer/ https://top500.org/news/japan-captures-top500-crown-arm-powe... (June 2020) > The new top system, Fugaku, turned in a High Performance Linpack (HPL) result of 415.5 petaflops, besting the now second-place Summit system by a factor of 2.8x. > Fugaku is powered by Fujitsu’s 48-core A64FX SoC, becoming the first number one system on the list to be powered by ARM processors. In single or further reduced precision, which are often used in machine learning and AI applications, Fugaku’s peak performance is over 1,000 petaflops (1 exaflops). > The new system is installed at RIKEN Center for Computational Science (R-CCS) in Kobe, Japan.

I got a Raspberry Pi 4 and naively thought that because it was ARM it used little power and didn't need fans. In a few weeks the board melted and now won't turn on. Was only running a few programs.

  How did the cpu throttling not kick-in and prevent this from happening? Mine gets hot and gets slow. It does not melt.

  I just got a Pi 4 and for a year now I've known it gets very very hot. I ordered this heatsink case for it https://smile.amazon.com/gp/product/B07VWM4J4L/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 https://smile.amazon.com/gp/product/B07VWM4J4L/ref=ppx_yo_dt... Should solve the problem. :)

For a home server, ARM is very nice as it has a better power to watt ratio than x86. So less heat to dissipate in your bedroom/home office.
