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.
AMD's Catalyst 14.6 for Linux improves some GL4 support that affects APITest, which is now leading to more of the APITest problems properly running outside of NVIDIA's binary driver. However, AMD still has more work to do as these results will show. Graham Sellers of AMD explained in an email to Phoronix, "We're working on the APITest suite and have made a number of improvements in the last little while. I don't think much of it has hit the public driver yet, and we still have some ways to go, but we're getting there. Expect to see performance improve over the next little while."
