AMD Ryzen Machine Crashes on a Sequence of FMA3 Instructions
Intel's AVX2 instructions don't crash the machine, but lead to an extreme increase in voltage and, thus, temperature. Sustained use of these instructions (say, for example, in signal processing and iterative parameter estimation algorithms implemented using routines in Intel's MKL) requires cooling way beyond what the usual boxed cooler that comes with an i7 CPU can deliver in order to prevent throttling.
