AMD's random number generator can't generate a 0?

A forum post alleges that certain AMD processors may fail to generate a zero value with RDRAND/RDSEED when requesting 16-bit outputs, while Intel systems do not show the same behavior. For CIOs and technology leaders, the key takeaway is less about this specific claim and more about the operational risk of relying on hardware random-number generators without validation: if true, it could affect cryptography, test reliability, and platform consistency across mixed-vendor fleets. IT organizations should treat hardware entropy sources as one input among several, verify behavior across CPU families, and stay current on firmware and microcode updates.
