NVIDIA GeForce GTX 970 Offers Great Linux Performance
Before getting to the OpenCL compute benchmarks are some of the synthetic GpuTest OpenGL benchmark results.
The Radeon R9 290 with Catalyst does rather favorably for several of these synthetic tests.
With Furmark the Radeon R9 290 is running just a small step ahead of the GeForce GTX 970.
The NVIDIA GPUs are back to blasting past the Catalyst Linux driver when it comes to the TessMark tessellation benchmark.
