Phoronix published a review on the Open-Source Linux Graphics: A10-7870K Godavari vs. i7-4790K Haswell vs. i7-5775C Broadwell
A quote from the article:
his latest i7-5775C Linux comparison is comparing the socketed Broadwell system to an AMD A10-7870K Kaveri Refresh / Godavari system and to an Intel Core i7 4790K Devil's Canyon rig. The i7-4790K is Intel's top-end Haswell desktop processor while the A10-7870K is AMD's recently released minor upgrade over the A10-7850K Kaveri. All three systems were running with 2 x 8GB of DDR3-2133MHz memory, solid-state storage, and running Fedora 22 Linux. The Fedora 22 installations all had their stable release updates installed at the time of testing plus the Rawhide Nodebug Kernel repository was enabled for using the Linux 4.2.0-rc2 x86-64 kernel. Mesa 10.6.1 from Fedora 22 supplied the stable user-space Intel/Radeon open-source graphics support. GNOME Shell 3.16.3 was the desktop in use during testing.Open-Source Linux Graphics: A10-7870K Godavari vs. i7-4790K Haswell vs. i7-5775C Broadwell @ Phoronix
