Hardware accelerated SIMD operations are almost necessary today for writing high-performance code. Prior to .NET Core 2.1, the only way to use the power of vectorization in .NET was via System.Numerics package, and Vector<T> type in particular (see the post SIMD with C# for the best introduction to this topic). Vector<T> provides great performance boost when applicable, but it offers fairly limited set of operations. Modern CPUs have hundreds of complex SIMD instructions, but Vector<T> offers on...
