The Intel whitepaer[1] recommends using the RDSEED over RDRAND whenever present. libstdc++ from GCC 10 will also use it in std::random_device. [ChangeLog][QtCore][QRandomGenerator] The system() random generator will now use the RDSEED instruction on x86 processors whenever available as the first source of random data. It will fall back to RDRAND and then to the system functions, in that order.
