Open-Source ATI R600/700 Mesa 3D Performance

,----[ Quote ]
| Our test system was made up of an Intel Core 
| i3 530 clocked at 3.31GHz, an ECS H55H-M 
| motherboard, 2GB of OCZ DDR3-1333MHz memory, 
| and a 64GB OCZ Vertex SSD. On the software 
| side we were running a snapshot of Ubuntu 
| 10.04 "Lucid Lynx" that included the Linux 
| 2.6.32-12 (x86_64) kernel, GNOME 2.29.6, X 
| Server 1.7.4 RC2, xf86-video-radeon 6.12.99, 
| Mesa 7.7, and an EXT4 file-system. Many other 
| distributions this quarter and next are 
| shipping with Mesa 7.7 and the Linux 2.6.32 
| kernel so this should provide an overall look 
| at what to expect in terms of the open-source 
| R500/600/700 3D performance. Besides the 
| already mentioned plans for future articles, 
| we will also be delivering fresh ATI Radeon 
| benchmarks from Fedora 13 to see how the 
| latest bleeding edge code is performing.



MD R600/700 2D Performance: Open vs. Closed Drivers

,----[ Quote ]
| From the three different test profiles we used and the two
| graphics cards that were tested, nearly every time the open-
| source driver stack wound up being faster than the Catalyst 9.10
| driver. Past tests of other graphics cards and drivers have shown
| the 2D performance to be better on the open-source side, albeit
| these 2D tests are not very real-world representative (nor do
| they reflect the CPU usage) and on the 3D side the proprietary
| Catalyst driver is significantly faster and more feature-rich
| than the current open-source code.

Version: GnuPG v1.4.9 (GNU/Linux)
