The last time I bought an AMD/ATI card was in 2011, I spent dozens of hours trying to find out why it was buggy and slower than my older Nvidia card of 2008... and finally I sent it back to reseller and buy an NVidia again...

Open source drivers or not, those AMD/ATI hardwares are now banished in my home and business as I only use Linux.

Michael, you should try testing one of the older mid range Radeon GPUs that are known to work ok on Catalyst, not only the newest/fastest ones that are known to be not implemented properly. Most people don't buy 500? GPUs anyway.

I posted this in another thread, but it fits here better:
Graham Sellers (AMD's OpenGL guy) said this in a recent tweet (about the Phoronix article with the benchmark):

My lesson learned... "Don't tell developers how to optimize their applications unless you also beat NV."

It would be childish, not balanced to include benchmarks intended to expose weaknesses of one specific vendor with the aim to "destroy" them. This particular set is obviously not out to assassinate anyone.

I am tired of appologizing for AMD
Originally posted by tusharkant15 View PostYou know I felt the same when I upgraded from a GT 630 to an R7 260X starting of the year. However I soon realized that it's got a lot to do with the games as well. I have all of the source games from valve and they work exceptionally well on my AMD card but when I run games from other vendors (Metro LL for example) they seem to be crap. Instead of people being so quick on pointing figures at AMD, should instead try and answer the question, why do games from valve span so perfectly on the entire GPU spectrum while most games from other vendors behave horribly? Valve clearly took their time to port their games and it clearly shows! I can say the same thing about games build using unity.
Smaller devs probably don't get the same level of support - be it API fixes or hardware for testing or development. Nvidia is famously good for providing support to even small vendors, even if that just means providing a free Shield or 750Ti to test against. Look how Michael has to buy all the AMD cards he tests, whereas all the NVidia provides test hardware, often on the first day shipping. Which one seems most committed to success?
Providing the best driver experience is a complex task that requires commitment on many levels. A good start is to provide consistent, high performance, stable drivers. Another important facet is providing support to the developers that use those drivers. AMD has proven inferior on both fronts. How is this not their fault?Last edited by deppman; 16 June 2014, 10:34 AM.

"This micro benchmark its thus irrelevant!"
This code represent (as official, and anything short of specification release can us get for OpenGL) FAST & RELIABLE alternative to DX12/Mantle.
If its not fast nor reliable, then something is wrong. Thus phoronix.com results represent valid and important data point to the GPU vendors (and game devs, and Valve which will probably start swinging their whips again at GPU vendors - if they haven't already).
Also since now we get that test integrated into PTS and thus openbenchamarking, game devs can get idea what works and what not.
