Stemming from Glibc semantics that effectively "cripple AMD"
while AMD CPUs with Glibc are not even taking advantage of Haswell era CPU

MATLAB is a popular math computing environment in use by engineering firms, universities, and other research institutes. Some of its operations can be made to leverage Intel MKL (Math Kernel Library), which is poorly optimized for, and notoriously slow on AMD Ryzen processors. Reddit user Nedflanders1976 devised a way to restore anywhere between 20 to 300 percent performance on Ryzen and Ryzen Threadripper processors, by forcing MATLAB to use advanced instruction-sets such as AVX2. By default, MKL queries your processor's vendor ID string, and if it sees anything other than "GenuineIntel...," it falls back to SSE, posing a significant performance disadvantage to "AuthenticAMD" Ryzen processors that have a full IA SSE4, AVX, and AVX2 implementation
