Intel is the exclusive designer of Intel CPUs and the exclusive owner/operator/user of Intel silicon fabs. Intel's on-die
Digital Thermal Sensors (DTS) and Platform Environmental Control Interface (PECI) use numerous Intel-patented technologies (like
these) which are unavailable to anyone else. Intel maintains the lead through an aggressive synergy of research and engineering (and marketing). Intel has essentially enjoyed (and milked) a dominant monopoly on x86/x64 tech for years while the competition has lagged woefully behind (until the launch of AMD Ryzen, anyhow, lol).
AMD is just design. They rely entirely on Samsung and GlobalFoundries (and perhaps TSMC) for fab. Each of them has a lot of innovative proprietary tricks and patents of their own, but I think the sad reality is that they currently suffer great deficiencies in some areas (like on-die thermal monitoring sensors/circuits) when compared vs Intel. My understanding is that the Intel sensors are smaller and more accurate and more responsive and better integrated (embedded "within" active circuitry) than their AMD/Samsung/etc counterparts (which are more like add-ons mounted "nearby" the circuitry).
And of course, in the end, we see whatever the firmware and software tells us. Mobo makers are eagerly embracing AM4. OS makers are eagerly embracing Ryzen SDKs. Game makers are even shifting from DirectX to Vulkan. But it will take time before everybody learns how to attain proper compatibility with AMD code, how to optimize for it, how (for companies like ROG!) to innovate and improve on it. Until that time we all have to accept whatever kludged workarounds we've been given, lol.
