When doing an 11-way Linux distro boot test they also found Clear Linux easily booted the fastest followed by the Clear-inspired Solus distribution. Clear Linux does work on AMD hardware and works on Intel CPUs back to Sandy Bridge but leverages its speed from optimized compiler settings, specially built libraries capable of AVX instructions on supported systems, a specially tuned kernel configuration, and other optimizations/patches.
Debian 9.2 and Fedora 27 "ended up being dropped from this article due to data overload," the article concludes, "and those distributions really not offering anything really different in terms of the performance."
Phoronix has more on the changes in Linux 4.14 -- and notes that its codename is still "Fearless Coyote."
The idea is that anyone in the world can send heavy workloads over the cloud to a Q.rad and have it render the task and heat a person's home in the process. The two industries that are targeted by Qarnot include movies studios for 3D rendering and VFX, and banks for risk analysis. Qarnot is opting in for Ryzen Pro processors over Intel i7 processors due to the performance gain and heat output. According to Qarnot, they "saw a performance gain of 30-45% compared to the Intel i7." They also report that the Ryzen Pro is "producing the same heat as the equivalent Intel CPUs" they were using -- all while providing twice as many cores.
While it's neat to see a company convert what would otherwise be wasted heat into a useful asset that heats a person's home, it does raise some questions about the security and profitability of their business model. By using Ryzen Pro's processors, OS independent memory encryption is enabled to provide additional security layers to Qarnot's heaters. However, Q.rads are naturally still going to be physically unsecured as they can be in anyone's house.
