https://community.intel.com/t5/Software-Archive/Using-EIST-Enhanced-Intel-SpeedStep-Technology-can-I-change-the/m-p/864964#M7893 <P>Hi, I'm looking for a multi-core Intel processor which supports frequency scaling of each CPU core individually.<BR />I found thatthe EIST(Enhanced Intel SpeedStep Technology) supports frequency scaling of the CPU dynamically, but is it also possible to scale the frequency of each CPU core dynamically on multi-core Intel processors (e.g., Xeon, core2-quad, i7)?<BR /><BR />So, my question is,<BR />1. Is there any processor model that supports per-core frequency scaling (DVFS) among Intel's multi-core processors? <BR />2. If there exists, Is the latest Linux kernel implements per-core frequency scaling through ACPI-competable device drivers (e.g., cpufreq-acpi)?<BR /><BR />Any answer will be appreciated.<BR />Thanks.</P> Tue, 07 Apr 2009 08:30:03 GMT buriburi205 2009-04-07T08:30:03Z https://community.intel.com/t5/Software-Archive/Using-EIST-Enhanced-Intel-SpeedStep-Technology-can-I-change-the/m-p/864964#M7893 <P>Hi, I'm looking for a multi-core Intel processor which supports frequency scaling of each CPU core individually.<BR />I found thatthe EIST(Enhanced Intel SpeedStep Technology) supports frequency scaling of the CPU dynamically, but is it also possible to scale the frequency of each CPU core dynamically on multi-core Intel processors (e.g., Xeon, core2-quad, i7)?<BR /><BR />So, my question is,<BR />1.
