Calculating Uncore power consumption for sandybridge processors
Calculating Uncore power consumption for sandybridge processors
I am currently using sandybridge servers with E5-2670 chips. RAPL is being used for power measurements. The 3 domains provided are Package, Core and DRAM.
Calculating Uncore power consumption for sandybridge processors ...
It does not seem like Intel wants to go into great detail in describing the RAPL interfaces -- they are intended to be good enough for power control, ...
How does Intel's RAPL estimate the power consumption
