Among the benchmarks of Fedora 20 I published on Phoronix last month were of Fedora 19 vs. Fedora 20, GNOME Wayland benchmarks on Fedora 20, Ubuntu 13.10 vs. Fedora 20, and then ultimately a six-way Linxu distribution comparison.
For sharing today via OpenBenchmarking.org are some straightforward results of testing Fedora 20 out-of-the-box on an ASUS Zenbook Prime Intel ultrabook, then updating the system to the latest Fedora stable updates packages sans the kernel upgrade, and then lastly the updated software including the Linux 3.12 kernel.
Fedora 20 shipped with Linux 3.11 and a zero-day update of Linux 3.12 was sent down the pipe. Fedora 20 updates also provide Mesa 9.2.5 over Mesa 9.2.3 (sadly there's no Mesa 10.0 for Fedora 20) and a newer GCC 4.8.2 compiler snapshot.
Those interested in these quick results from the Intel Core i7 Ultrabook can find them on OpenBenchmarking.org via 1401076-PTS-FEDORA2018. This was just some testing I had done for the heck of it out of curiosity while over in Russia so the system used was limited to one of the development ultrabooks I had on me besides my Retina MacBook Pro and Acer C720 Chromebook.
