Power & Performance Tests With Fedora 24 Beta, Linux 4.6 Kernel
Next are some more numbers from the ASUS UX301LAA Zenbook with Core i7 4558U processor, 8GB RAM, and 2 x 128GB SSDs.
The Xonotic numbers didn't change much from Fedora 23 to 24, similar to the Lenovo Broadwell tests.
The power consumption numbers have improved since the debut of Fedora 23, but not by much.
Fedora 24 Beta had an issue with consuming noticeably more power on average than Fedora 23 while compiling the Linux kernel on this Haswell system, but the issue seems to be largely resolved with Linux 4.6 (but it's peak power use is still higher than found under F23).
When looking at the system power consumption data for this ASUS Zenbook over the course of many benchmarks, Fedora 24 beta with Linux 4.6 is roughly on par with Fedora 23. For this notebook under Fedora 24 Beta with the default Linux 4.5 kernel at the time, it regressed power-wise compared to F23 but it's good to see that those regressions appear corrected by Linux 4.6.
If you wish to dig through more of this data, you can find all the raw individual numbers for the Thinkpad X1 Carbon and Zenbook via OpenBenchmarking.org. With few exceptions, the numbers are close to the same between Fedora 23 and the current state of Fedora 24.
