Enabling HyperZ Is Still An Easy Way For Faster RadeonSI Performance

With this week's Catalyst vs. RadeonSI Gallium3D driver comparison for the A10-7800 Kaveri APU with Radeon R7 Graphics, the default driver settings were used since after all it's what most Linux gamers and desktop users will utilize when running either driver. However, for those wanting to tune their open-source driver to get a bit higher number, enabling HyperZ is still an easy win.

AMD Kaveri: Catalyst vs. RadeonSI Gallium3D On Linux

With the recently released AMD A10-7800 Kaveri APU I carried out some new benchmarks comparing the open and closed-source Linux GPU driver performance for AMD with their Catalyst and RadeonSI Gallium3D solutions. When running the open-source Ubuntu driver tests, multiple versions of Mesa and the Linux kernel were used.

AMD Catalyst 14.6 Does Slightly Better With APITest OpenGL Tests

Last month I published some benchmarks where NVIDIA slaughtered AMD's Catalyst driver in APITest benchmarks, a set of OpenGL 4.x test cases. While these are just micro-benchmarks of modern OpenGL and designed for showing off potential solutions for problems to leading to lower driver overhead, there's been some improvements within the Catalyst 14.6 Beta on Linux. Up today are some new benchmarks of APITest using the latest AMD and NVIDIA drivers.

Even With Re-Clocking, Nouveau Remains Behind NVIDIA's Proprietary Linux Driver

Starting out the last week of July's Linux benchmarking on Phoronix is a fresh comparison of several NVIDIA GeForce graphics cards when comparing the performance of the latest open-source Nouveau driver against the latest NVIDIA proprietary Linux graphics driver. While the Kepler cards now support GPU re-clocking, the results aren't quite ideal yet.
