GPGPU Performance

Next up, we have a couple of GPGPU benchmarks with SiSoft SANDRA 2012 SP4 and Computemark. We tested all of the cards represented here with SANDRA's GP (GPU/CPU/APU) Processing benchmark, using the OpenCL GP Processor option and have the aggregate and native double-shader scores for you reported below.

GPGPU Performance

The Radeon HD 7900 series cards simply dominated all of the GeForces in this SANDRA GPGPU benchmark. According to this benchmark, the Radeon's offer 2x - 4x the performance of NVIDIA's GeForce GTX 600 series offerings.

Compute Shader Benchmark

The cards were much more tightly grouped in the Computemark test. The Radeon HD 7970 cards still take top honors, but in this test the Radeon HD 7950 trails the GeForce GTX 690 cards, while the GeForce GTX 670 brings up the rear.
