… However, it should theoretically apply to almost all modern CPUs because it works by observing the power algorithms behind the Dynamic Voltage Frequency Scaling (DVFS) technique, a staple of modern processors. As such, this isn't a microarchitecture-specific attack — any processor with dynamic power and thermal management is potentially impacted. Intel says this has prompted it to share its findings with other chipmakers so they can assess any potential impact.
Apple Cinnamon uses a more-or-less fixed clock speed, without the "turbo to 5GHz" common on Intel processors.
