28-Way Radeon GPU Comparison Under Linux
An anonymous reader writes "Phoronix has conducted a 28-way Radeon graphics card comparison under Linux that illustrates the differences among the open-source and closed-source graphics drivers."

the fact that in TFA they say it's AMD comparison on Oktoberfest. These people don't take breaks!
I rarely respond to comments. Also, don't ask for clarifications: a brain and Google are faster, believe me!
well assuming there were a gallium or similar driver for them...

Is my internet sucking again or did the site already get slashdotted?
Thank you Phoronix, but I'll pass on that one...
30+ pages filled images or graphs. The gist of it: 3D capabilities of open source drivers still suck, and the newer cards suck worse.

Just reading the title in my RSS and I knew it would be another terrible Phoronix article. How many years has it been that slashdot has been funnelling eyeballs and thus revenue to this awful site. It has legitimized them amongst those who don't know any better... Disgraceful.
Another Phoronix article, what will it include:
1) A comparison done ignoring an obviously major changing piece of software
2) A comparison done with no regard to common hardware
3) Utter and complete nonsense proved to newbies using flashy charts
Sadly its usually all 3.
Yeah they deserve to be slashdotted for the design madness that multiplies readers by x38 or more.

I have a better solution: no one should be able to post the first post!

I am a proud AdBlock user. I think I speak for the rest of the AdBlock users when I say that if your publication cannot survive without annoying and intrusive advertisement, we would prefer that it go the fuck away and stop making an ugly hole in the internet.
I hope Phoronix tanks, and soon. I prefer my articles in an essay format. For those of you who slept through elementary school, such a format involves an introduction, a body, and a conclusion. Crying about how much it cost you to develop an article that people aren't willing to pay for is what losers do. Winners go home and fuck the prom queen.

On the subject of AMD drivers, they stink. Both the closed source ones and the open source ones. The flgrx drivers do not appear to like gnome-shell AT ALL and the open source drivers aren't exactly speed demons.
compare all these cards, but jesus christ after 40 pages of clickthrough i dont really care what conclusion the guy came to.
its a general waste of my time and effort.
Good people go to bed earlier.
Let he/she who is without sin post the first post!
Your modest proposal is unworkable. Let me make it a bit less satiric: No one should be able to keep the first post for a whole discussion. Randomize the order of the top-level posts that come in within the first few minutes of posting. This would also make another practice less effective: replying to the first post to make your own comment more visible.
FTIW, I like Phoronix!
They are the only ones testing a wide variety of hardware using Linux.
There is no contender and I have based many buying decisions on their articles. I still read articles testing hardware on Windows, but their results not necessarily translate to Linux.
So, FTIW, I like Phoronix!
With the very light workload of idling and video playback, the graphics cards when using the Radeon driver already tended to be warmer than the Catalyst driver, which properly supports PowerPlay and other power management technologies by default. The open-source power management options must be toggled manually and even then the mileage may vary. Some of these graphics cards were easily 8~10+ Celsius warmer when using the open-source driver! The Radeon HD 5830 was more than 20C warmer with the open-source driver. (The temperature in my office during all of this testing was maintained at about 23.3C.
To not a lot of surprise, the system power consumption was greater with the open-source driver over Catalyst. This in part due to the lack of GPU core / memory re-clocking by default and other missing or disabled power management options where as the Catalyst driver is able to effectively handle this in a seamless manner.
When running Warsow and monitoring the system metrics, the CPU usage remained much lower with the open-source driver over Catalyst. This CPU usage difference is perhaps due to a bottleneck in the driver code and needing to wait on the GPU to finish slowly execute its operations. The CPU usage difference was also similar when running Nexuiz.
When the GPU under test is experiencing full load, each of the tested graphics cards -- the ones with thermal sensors at least -- tended to have around the same core temperature.
When the system was idling, the GPU temperature was higher and the system was burning through more power with each of the graphics cards. However, with the load provided by Warsow on each of the GPUs, there was not much of a power consumption difference since each of the GPUs are running at their maximum power states (the Radeon always does by default, where as the Catalyst driver clocks down on newer hardware and has its other power management features when not experiencing complicated loads). In fact, the power consumption with the open-source stack tended to be slightly less for some of the tested graphics cards with Warsow 0.61, but this is the game where barely any of the Radeon graphics cards can run at a playable frame-rate with Gallium3D.
Hopefully you enjoyed this very extensive look at the ATI/AMD Radeon Linux drivers across a large selection of hardware with valuable information on each of the pages. Each driver has its own distinct advantages and disadvantages depending upon your hardware/software configuration, intended workload, and what features are most important to your needs. Neither driver, however, is perfect. The open-source Radeon Linux driver is also arguably the best open-source Linux driver for discrete graphics cards and at least it has the backing of AMD -- unlike NVIDIA that provides no open-source support, but the community relies upon reverse-engineering to produce a driver with mixed-results. If the open-source driver works on your system and meets all of your needs, great, but otherwise there is the Catalyst Linux driver.
FWIW, I like Phoronix...

Your point is rather invalid since your post is not the first. JavaBear's idea would only prevent the first post being created by an AC, not replies to that post.

Not really, since the putz didn't even make FP anyway.
I don't hate Phoronix either, but he's in a bad place trying to monetize eyeballs connected to brains capable of tracking more moving objects than the Chicago-Washington corridor after a threat level upgrade from orange to burnt lavender. The mental airspace is crowded enough without adding biplanes with banners.
Why do the people crowing "use NVidia" put me in mind of Jack Nicholson shouting "You can't handle the documentation!" Damn straight, ya bunch of cowards.
Apparently, with enough documentation, no programming task is shallow after all. Didn't prominent memes in the open source camp put forward the notion that the only thing holding us back was lack of technical disclosure? Where are those voices now?
When the going gets tough, the tough get Binary Blobs. Not the banner I originally unfurled.

ATI keeps promising to provide enough specs for proper support, and it keeps not happening until well after the fact. That, or the developers are a bunch of douches. I don't believe THAT, though, because the driver actually does work super-well for antique (well-known) hardware. Until the situation resolves itself (and ATI drivers have always been trash - I was getting crashes from ATI Mach32 drivers in Windows 3!) there is nVidia. Or maybe someday Intel will figure out how to make a GPU worth using for more than a navigation system.
