Intel Ivy Bridge CPU Performance Per Watt Some system power consumption monitoring of Intel Core i5 2400S, i5-2500K, i5-3470, and i7-3770K processors under Linux. Plus CPU temperature monitoring too. Different workloads along with Linux performance-per-Watt for these Intel Sandy Bridge and Intel Ivy Bridge processors. Benchmarking by Michael Larabel for a future article on Phoronix.com for Ivy Bridge power efficiency / performance-per-Watt under Ubuntu Linux.
