7-Way Linux Laptop Comparison From Sandy Bridge To Broadwell
The ASUS i3-5010U laptop led again with the OpenSSL test for delivering the best performance-per-Watt. This 15.6-inch laptop had an average power draw of just 14.3 Watts.
Lastly is a look at the power use for these seven laptops on Ubuntu Linux when carrying out all of the power-monitored tests. The Core i3 5010U laptop had an average power draw of 15.8 Watts as the lowest average while it bottomed out at 7.4 Watts during the brief moments of idling. The Core i5 5200U Broadwell had an average power draw of 19.8 Watts with it bottoming out at 8.4 Watts.
Well, if you've been curious about the evolution of Intel ultrabook/laptop performance over the past few years, hopefully you found this fresh data insightful. If you would like to compare your own Linux system(s) against this data if you've been thinking about a possible upgrade, you can compare your own laptop's performance to this data by installing the Phoronix Test Suite and run phoronix-test-suite benchmark 1512142-GA-LAPTOPSDO70.
If you want to do a power efficiency comparison with your laptop running on battery power, run PERFORMANCE_PER_WATT=1 MONITOR=sys.power phoronix-test-suite benchmark 1512143-GA-POWERDONE28.
