Rodinia's OpenCL Myocyte test started off with a very poor showing for the AMD Radeon GPUs in relation to the NVIDIA GeForce graphics cards. Some NVIDIA GPUs though failed to properly run this scientific test-case.

Rodinia's Heartwall test at least was able to have a good showing for the ten graphics cards tested with the Radeon HD 7950 and R9 270X and NVIDIA GTX 680 graphics cards doing the best.

Rodinia Leukocyte was another test where the NVIDIA performance was much better than on the Radeon side being very slow and virtually showing no performance difference between the hardware tested.

With the OpenCL Particle Filter in Rodinia, the Radeon hardware was finally competitive and the three higher end AMD GPUs were able to outperform the GeForce GTX 680 Kepler.
