http://lists.freedesktop.org/mailman/listinfo is where most of the phoronix articles are from along with http://planet.freedesktop.org/
If you use RSS aggregation and subsribe to some planets like freedesktop or fedora and subscribe to some of the above mailing lists (filtered in gmail) you'll find you get all the info of this site
Michael doesn't pull these articles out of his ass (even though sometimes they may read like they have)
While following the lists does get you the same info, the volume is rather huge. I appreciate how Michael filters the important bits for us.
This is not the only article where Michael mentions AdBlock. So let's open a seperate topic for it and use this one for discussions about Radeon cards on Linux.
I expect the higher CPU usage with Catalyst is mostly due to just pushing a lot more data to the GPU because of the higher performance, but it's also possible that it does more work optimizing everything in the driver and that ends up costing it more than the simpler OSS driver.
